Third, the efficacy and safety of the system for the remedy of bifurcation aneurysms remains unsure women's health clinic roseburg oregon cheap 60mg raloxifene amex. In reality, the safety of crossing or jailing major bifurcation or department vessels with the gadget (regardless of the placement of the treated aneurysm) stays uncertain breast cancer 000 negative ductal purchase raloxifene 60mg amex. However, till a bigger knowledge set is available, the amount of protection that may be safely applied in these anatomic locations stays unsure breast cancer network of strength generic raloxifene 60 mg overnight delivery. Flow Diverters: Summary Flow diverting gadgets symbolize a new treatment paradigm for intracranial aneurysms menopause journal buy raloxifene canada. Many advanced aneurysms that were once regarded as untreatable or to require a deconstructive therapy with mother or father vessel occlusion may be amenable to reconstruction with these newer gadgets. Moreover, the most important shortcomings of endosaccular aneurysm therapies-incomplete aneurysm occlusion and aneurysm recurrence-may be decreased with this technique of circumferential reconstruction of the mother or father vessel. Further investigation will higher define the security, efficacy, and ultimately the appropriate role for these units within the armamentarium of units used for endovascular aneurysm remedy. Flow modifications attributable to the sequential placement of stents across the neck of sidewall cerebral aneurysms. A novel endovascular treatment of a wide-necked basilar apex aneurysm by using a Y-configuration, double-stent method. Lavine Hunterian ligation refers to one of the oldest successful interventions for arterial aneurysms-ligation of the femoral artery to treat a popliteal aneurysm by John Hunter in 1785. Because refinements within the coiling expertise used to deal with cerebral aneurysms have continued to broaden the scope of intracranial aneurysms that might be repaired by coiling, hunterian ligation is extra incessantly relied on as a last resort to treat only probably the most surgically inaccessible and tough aneurysms. Historically, hunterian ligation has referred to the everlasting sacrifice of a father or mother artery to forestall access of blood to the aneurysm. This method has additionally been known as "deconstructive" remedy, in contrast to "reconstructive" remedy, which refers to the focused occlusion of a vascular abnormality without impairment of blood move in the parent vessel. Hunterian ligation most often targets complicated aneurysms, but sacrifice of the mother or father artery has also been used for the treatment of a extensive range of neurosurgical entities, together with hemorrhagic stroke, vascular tumors, arteriovenous malformations, fistulas, and arterial dissections. Since the event of endovascular balloons within the early Nineties, father or mother vessel occlusion has turn out to be potential by way of transfemoral entry, paradoxically the identical vessel that Hunter first ligated in 1785. Certain traumatic pseudoaneurysms and infectious aneurysms by which the danger related to endovascular intervention is excessive may be good candidates. Surgeons have noticed that as many as two thirds of giant intracranial aneurysms may not be amenable to clip reconstruction or endovascular remedy because of the situation of the aneurysm or its morphology. The major treatment question when contemplating endovascular hunterian ligation is whether to carry out an arterial bypass earlier than everlasting vessel occlusion. Whenever attainable, complex ruptured aneurysms that require hunterian ligation are treated in delayed trend or temporized with partial endovascular occlusion. The determination rubric behind testing for cerebrovascular reserve and performing endovascular hunterian ligation varies amongst establishments; some surgeons advocate a common reconstructive method with bypass, whereas others apply selective endovascular hunterian ligation. His pioneering try resulted in stroke, thus leaving the primary successful carotid ligation to Astley Cooper in 1808. Carotid ligation, both common or inside, was a typical form of treatment of ruptured aneurysms until the late 1960s. In addition, special clamps had been developed that allowed treatment within the awake state so that if neurological impairment happens with gradual occlusion, circulate might be restored quickly. Nevertheless, it was discovered to be effective in stopping rebleeding over the quick term (6 months) in a randomized trial comparing abrupt frequent carotid occlusion with mattress relaxation in sufferers with a ruptured posterior communicating aneurysm. Development of the Drake tourniquet permitted the surgeon to briefly occlude an artery the day after surgical procedure, when the patient had absolutely recovered from anesthesia, and therefore observe whether or not sacrifice of the father or mother vessel could probably be tolerated. As beforehand mentioned, this system simultaneously occludes the mother or father vessel proximal and distal to the vascular lesion. The case sequence of 11 patients by Kai and colleagues reported good neurological outcome with only one transient adverse outcome. Outcomes have been reported at a mean follow-up of 76 months, with three patients dying throughout treatment, transient ischemia growing in six, delayed infarction creating in two, and the aneurysms of 1 patient enlarging after endovascular occlusion and requiring surgical clipping.

With respect to biologic remodeling, solely a single case is out there within the literature describing the histopathologic appearance of an implanted Neuroform stent at autopsy women's safety and health issues at work purchase cheap raloxifene online. After this patient died of unrelated causes four months later, an analysis of the explanted aneurysm demonstrated de novo fibroelastic tissue rising across the aneurysm neck and average intimal thickening along the stented segment of the parent vessel menopause periods buy raloxifene now. Clinical Evidence the available knowledge from clinical case sequence have offered some further, albeit preliminary, proof that stenting might improve the durability of endovascular aneurysm therapy breast cancer 6s discount raloxifene 60mg visa. Stent placement theoretically could enhance r the hemodynamics by straightening the angulation of the vessel (B) to direct the dominant move jet into the nativebasilarartery(large arrow)ratherthantheaneurysm and the struts of the stent disrupting the move jet intotheaneurysm(smaller arrows) womens health magazine careers generic raloxifene 60mg line. These traits would predict a really high price of recurrence with standard coiling techniques. Evaluation of mid- and long-term follow-up results from the collaborative Barrow Neurological Institute�Cleveland Clinic database demonstrated a stunning degree of long-term durability in aneurysms treated with stent-support. Of the 28% aneurysms that demonstrated recanalization, outlined as any amount of elevated filling compared to the immediate postcoiling end result, many have been either very massive or big aneurysms. Procedural problems encountered by operators performing aneurysm coiling through in situ stents caused some to begin aneurysm coiling utilizing a balloon-assist technique with stent deployment carried out afterward-not only to stabilize the coil mass throughout the aneurysm but in addition in an attempt to rework the mother or father vessel and thereby improve the long-term durability of the initial treatment. This technique avoids displacement or injury of the stent that can be inadvertently created during the manipulation of a microcatheter both into the stented section of the father or mother vessel or by way of the stent tines and into the aneurysm. High Metal Surface Area Stents (Flow Diverters) the idea of mother or father vessel reconstruction is shortly advancing with the recent development of dedicated flow-diverting endovascular constructs designed for intracranial use. Currently, these flow-diverting units are high steel surface space protection, stent-like constructs. The preliminary angiogram was interpreted as regular;nevertheless,inretrospect,theremay be a tiny bleb arising in the area of a midbasilar perforator. A, Conventional angiography following the preliminary stent-supported embolization demonstrates residual filling alongside the whole aneurysm neck and into the aneurysm fundusinferiorly(arrow). A B endovascular remodeling to induce aneurysm thrombosis with out the usage of further endosaccular occlusive units. At the identical time, the pore size of the constructs is large sufficient to permit for the continued perfusion of branch vessels and perforators arising from the reconstructed segment of the parent vessel. The balloon catheter on which the device is mounted could either be designed for over-the-wire delivery, whereby the microwire exits the proximal hub of the delivery catheter, or monorail delivery, whereby the microwire exits the side wall of the distal aspect of the catheter. Over-the-wire delivery allows for the transmission of greater forward stress from the proximal microcatheter to the distal facet. In most circumstances, entry across the targeted landing zone for stent deployment is achieved with a regular microcatheter and 0. These units not solely facilitate the therapy of complex lesions but additionally have the potential to reinforce the sturdiness of traditional endosaccular aneurysm occlusion. At some point in the future, stand-alone flow-diverting constructs may provide a definitive means by which to realize a durable cure of selected aneurysms, utterly obviating the necessity for endosaccular implants in these cases. The microcatheter is manipulated properly past the targeted touchdown zone into the distal intracranial vasculature and the microwire is eliminated. An injection of contrast material through the microcatheter or guiding catheter can be carried out to verify an sufficient intravascular position of the microcatheter. When the stent is in enough place, an angiographic run may be performed to verify optimal positioning and to evaluate for any problems of stent navigation or wire manipulation. When the operator is happy with the stent positioning, the stent is deployed through balloon inflation. The balloon catheter can then be fully deflated and eliminated, leaving the deployed stent behind within the artery. Once deployed, the units present a much greater degree of metallic surface area coverage in comparison with the self-expanding devices (10% to 20% metalto-artery ratio in contrast with 6. Although difficult to visualize underneath fluoroscopy, these devices are more radiopaque than the self-expanding stents. A newer technology of balloon-mounted stents are being designed for intracranial use. These devices have been engineered to be more deliverable and less traumatic than the predicate devices designed for coronary functions. These units could have indications for the remedy of each cerebral aneurysms and intracranial atherosclerosis. In comparison Current Applications the rigidity of the devices and their supply systems poses important limitations to the navigation of those gadgets to the targeted father or mother artery landing zone. To navigate the tortuous cerebrovasculature, the operator was often required to attain aggressive guiding catheter positions to place stiff exchange-length wires into the distal branch vessels and apply important ahead pressure to the delivery system to attain movement.

The time has passed when the primary target was on the rhetoric of figuring out whether or not clipping or coiling was the superior choice. Our understanding of those lesions and problems of therapy has taken us to some extent at which cases could be analyzed critically and decisions highly individualized. Critical variables embrace patient age and subsequently years of exposure to recurrence, medical grade, neck width, measurement of the aneurysm, associated thrombosis, and anatomic variance. If a surgical strategy is determined to be optimum for the person affected person, enormous concentration should be targeted on every element of the operation as a result of the margin for error is nonexistent. The surgeon ought to be skilled, relaxed, and psychologically ready for surprising problems of anatomy or intraoperative rupture. During occasions of short-term arterial occlu- Full references could be discovered on Expert Consult @ McDougall the past 30 years have witnessed landmark advances within the endovascular administration of intracranial aneurysms. The technical nuances, potential complications, and embolic units employed differ from one aneurysm location to the opposite. Knowledge of those techniques and of how they apply to particular aneurysm places is the one most essential means of stopping issues. Several research have validated the efficacy and safety of coiling these aneurysms. Nonetheless, they continue to be a difficult subgroup of lesions to treat21 because of a quantity of factors: issue catheterizing the A1 segment, tortuosity at the A1-2 junction, and suboptimal imaging attributable to multiple arterial branches arising close to the aneurysm site. Improvements in catheter and microwire technology and refinement of threedimensional (3-D) angiography have decreased these limitations to a certain degree. Inferiorly and posteriorly projecting lesions are harder to coil because visualization is often suboptimal and catheter stability inside the aneurysm could be tenuous. Steam shaping the catheter tip or using an appropriately angled catheter can reduce the tendency of catheter "sit back" while coiling. The operator may be pressured to reposition the catheter and to recatheterize the aneurysm a number of times before a secure coil mass is achieved within the lesion. These repeated efforts improve the probability of those aneurysms rupturing in the course of the process. The smaller caliber of the balloon catheter microwire and the relative stiffness of the device itself can preclude navigation alongside this phase. A microcatheter exchange, during which a extra supple and navigable microcatheter is first directed into the anterior cerebral circulation after which exchanged for the balloon catheter over a protracted microwire, can be used when balloon remodeling is required. Nevertheless, this exchange approach is technically difficult and poses a excessive danger of devastating issues, similar to vessel perforation and thrombosis. Another elegant, but technically difficult, means of balloon remodeling is to navigate a microcatheter into the aneurysm from one A1 and the balloon catheter from the contralateral A1. Finally, the so-called kissing balloon technique, in which balloons are navigated from both sides and inflated while a 3rd catheter is used to coil the aneurysm is maybe essentially the most challenging catheter approach used to treat these lesions. The risks of stenting, together with the technical elements related to catheterization and the need for long-term single and sometimes twin antiplatelet medical therapy, must be weighed against the comparative dangers of clip ligation. Placement of an oversized stent on this region may encourage in-stent stenosis or thrombosis.

The group of the colon is somewhat just like that of the intestine; the difference is that it lacks villi and Paneth cells women's health clinic overland park ks order generic raloxifene line. This balance is determined by the presence of adverse suggestions loops, and Hh signaling has been proven to play a significant role on this loop women's health center southington ct order raloxifene 60 mg otc. During growth, each Shh and Ihh are expressed within the intestinal epithelium; conflicting knowledge exist on the expression of Shh in the grownup gut menopause uterus pain generic 60mg raloxifene. Shh in the grownup mouse intestine was not detected by in situ hybridization,182 nevertheless it has been shown by using an ShhGfp reporter mouse that low levels of Shh could also be expressed by uncommon cells on the crypt base menstruation migraine cheap 60 mg raloxifene visa. Hh-responsive cells within the adult intestine embrace easy muscle precursor cells, clean muscle cells, myofibroblasts, and pericytes. Other mesenchymal factors have been instructed, similar to Hh responsive cells Villus Ihh Enterocyte Goblet cell Entero-endocrine cell Paneth cell Stem cell Transit amplifying cell Crypt Mesenchymal cell Shh In the grownup gut, transit-amplifying cells either transfer downward to type Paneth cells (only in the small intestine), or upward to form the opposite intestinal cell lineages. Ihh is the predominant Hh expressed within the grownup intestine and alerts to the mesenchyme. Chapter 10 Hedgehog Signaling in Gastrointestinal Morphogenesis and Morphostasis 317 Ihh Mature cell Mesenchymal goal cells Wnt Ihh secreted by the differentiated cells acts on the mesenchymal cells, such as clean muscle cells, which secrete elements that subsequently negatively regulate precursor cells at the base of the crypt. Activin signaling is mediated by way of pSmad2,three, which is energetic in regular crypts, however lost in Ihh mutant mice. Therefore, lack of Activin signaling could also be the purpose for increased Wnt signaling and epithelial proliferation in mice with lowered Hh signaling, however this risk nonetheless needs to be additional investigated. The authors discovered that myeloid cells, together with dendritic cells, are direct targets of Hh signaling during each homeostasis and beneath inflammatory conditions. In this mannequin loss of Ihh expression could probably be induced particularly in the small intestinal epithelium by injections with -naphthoflavone. Both models confirmed enlargement of the proliferative crypt area with lengthening of the crypts, loss of easy muscle cells from the villous core, and, ultimately, villous atrophy and irritation in the lamina propria. By adding recombinant Hh protein, Hh signaling could presumably be reactivated within 24 hours and the levels of proinflammatory cytokines have been lowered, suggesting Hh is a vital anti-inflammatory sign within the intestine. After extended lack of Ihh expression, progressive irritation was noticed with inflow of macrophages, T-cells, and neutrophils into the intercrypt areas and the event of in depth intestinal fibrosis. Thus, lack of Ihh expression, which would usually outcome from damage to the intestinal surface epithelium, seems to initiate an intestinal wound healing response, which if unresolved (such as within the Ihh mutant mice during which Ihh is permanently lost), results in the development of continual irritation and fibrosis. In each fashions the noticed villous atrophy strongly resembles histology noticed in sufferers with celiac disease. However, no improve in intraepithelial lymphocytes was noticed, whereas accumulation of those cells is a hallmark of celiac disease. This makes loss of Ihh as a causal position for the development of celiac illness unlikely. Unresolved lack of Ihh from the intestinal epithelium in the end leads to loss of easy muscle cells from the villi, mucosal damage, villous atrophy, and chronic enteritis with intestinal fibrosis. Other cells within the liver embrace the Kupffer cells, stellate cells, endothelial cells, and lymphocytes. Kupffer cells are the macrophages of the liver and are located inside gaps between sinusoidal endothelial cells. In people, liver progenitor cells are sometimes described as intermediate hepatobiliary cells. The origin of oval cell precursors remains to be unclear: nevertheless, it has been advised that oval cells are bipotential transient-amplifying cells derived from stem cells that reside within the biliary tree. Bile ductular cells had been the predominant source of Ihh, whereas oval cells, immature ductular cells, and myofibroblasts were the Hh responsive cells. They secrete inflammatory cytokines, chemoattractant proteins, and inhibitors of apoptosis. In addition, reactive cholangiocytes lose some of their epithelial phenotypic traits. In conclusion, the studies discussed beforehand describe a job for Hh signaling in regeneration and fibrosis of the liver. However, to achieve more perception into the role of Hh signaling in the (damaged) liver, more in vivo research can be useful. Since lots of the antibodies used for immunohistochemical staining of the Hh pathway have been shown to be unreliable,seventy nine the utilization of different strategies, such as in situ hybridization, are necessary extra instruments to suppose about.

T his m em brane separates the upper a half of the anal canal, derived from endoderm, from the decrease part, called the proctodeum, which is form ed by an invaginating pit lined by ectoderm. The m em brane breaks down in the seventh week to create the opening for the anus. A nother im portant result of cephalocaudal progress and lateral folding is partial incorporation of the allantois into the body of the em bryo, the place it kind s the cloaca. Pharyngeal pouches, epithelial lining of the lung buds and trachea, liver, gallbladder, and pancreas. The urinary bladder is derived from the cloaca and, a t this stage of development, is in open connection with the allantois. Part I � General Embryology the distal portion of the allantois rem ains in the connecting stalk. By the fifth week, the yolk sac duct, allantois, and um bilical vesseis are restricted to the um bilical regi�n. It may operate as a nutritive organ during the earliest levels of development prior to the establishment of blood vessels. It additionally contributes a variety of the first blood cells, though this role could be very transitory. One of its major functions is to accommodate germ cells that reside in its posterior wall and later migrate to the gonads to kind eggs and sperm (see Chapter 16). Henee, the endodermal germ layer initially forms the epithelial lining of the primitive intestine and the intraembryonic parts of the allan tois and vitelline duct. Thus, each cluster lies on a separate chrom osom e, and the genes in every group are numbered 1 to 13. Genes with the identical num ber, but belonging to completely different clusters, kind a paralogous group, similar to H zero X A four, H zero X B four, H zero X C 4, and H 0X D 4. The pattern of expression of these genes, along with evidence from knockout experim ents during which m ice are created that lack a quantity of of these genes, supports the hypothesis that they play a job in cranial-to-caudal patterning of the derivatives of all three germ layers. During the second m onth, the exterior appearance of the embryo is modified by a rise in head measurement and formation of the limbs, face, ears, nose, and eyes.

A dissection plane is then developed between the temporalis fascia and muscle, below the second fats pad breast cancer chemotherapy generic 60 mg raloxifene otc. Next, the frontozygomatic and temporal zygomatic processes and superior orbital rim are exposed by elevating the temporalis fascia off the respective bony surfaces with a periosteal elevator menstrual anxiety raloxifene 60 mg lowest price. After the temporalis muscle is elevated and retracted from the squamous temporal bone, a standard pterional craniotomy is performed, followed by the orbitozygomatic osteotomy breast cancer north face generic raloxifene 60mg on-line. The temporalis muscle is again launched and placed over the craniectomy defect in preparation for the orbitozygomatic osteotomy 1st menstrual cycle buy generic raloxifene 60mg on-line. For the conventional orbitozygomatic method, an oscillating noticed is used to make six osteotomies. The first osteotomy is made at the base of the zygoma by placing the saw on the zygomatic root just above the temporalis muscle. It must not be placed too deep to keep away from violating the capsule of the temporomandibular joint. The second minimize begins just anterior and inferior to the temporal process of the zygomatic bone and proceeds laterally to medially while directed slightly inferiorly. It stops within the midportion of the malar eminence on the zygomaticofacial foramen, which is connected with the third reduce. This latter cut extends from the inferior orbital fissure from throughout the orbit through the orbital surface of the temporal bone and connects the second reduce at an apex. An inverted V is thus created on the malar eminence; the left and right hyperlinks are the second and third cuts, respectively. The fourth cut extends by way of the orbital surface of the frontal bone posteriorly towards the superior orbital fissure. If extra medial entry is required, the supraorbital nerve can be mobilized from its foramen with an osteotome. If the foramen is high above the orbital rim, the nerve may be sacrificed, but brow numbness will outcome. It extends posteriorly from the inferior orbital fissure across the larger wing of the sphenoid bone and through the posterior orbit. Alternatively, it might possibly join the fourth and fifth cuts simply proximal to the superior orbital fissure. A rongeur can be used to take away the residual bony island of the larger wing of the sphenoid till the dural fold of the superior orbital fissure is identified. Importantly, the orbitozygomatic strategy may be tailored to go well with particular person circumstances (modified orbitozygomatic approach) when a lesion requires much less rostral visualization. However, for most deep-seated lesions, full elimination of the orbital roof and zygoma is indicated. To guarantee precise reapproximation at closure, holes could be drilled for a cranial fixation plate earlier than the osteotomy is eliminated. Tacking sutures are positioned deep towards the orbital apex and anchored around the secure fishhooks. The working microscope is then brought into the sector, and a transsylvian or subtemporal strategy is undertaken in atraumatic fashion. The working distance to lesions within the parasellar region and the interpeduncular fossa is about three cm shorter with an orbitozygomatic method than with a standard frontotemporal approach. A more upward and oblique view of the sylvian fissure, third ventricle, and higher brainstem could be achieved with less retraction on the temporal and frontal lobes. Patients ought to be forewarned of serious postoperative periorbital edema and diplopia, which usually resolve inside a week. On postoperative day 1, sufferers can start jaw workout routines to avoid restricted vary of motion of the temporomandibular joint as a outcome of scarring of the temporomandibular ligament and joint capsule. Atrophy of the temporalis muscle can be minimized through the use of monopolar cauterization judiciously and by reapproximating the superior aspect of the temporalis muscle to a small muscle cuff of fascia left along the superior temporal line. The affected person could be positioned lateral, susceptible, or supine with a sandbag beneath the ipsilateral shoulder.

Initially, the atrioventricular canal gives access only to the primitive left ventricle and is separated from the bulbus cordis by the bulbo (cono) ventricular flange menopause insomnia treatment buy raloxifene 60mg with visa. Near the tip of the fifth week, nevertheless, the posterior extremity of the flange terminates almost midway alongside the bottom of the dorsal endocardial cushion and is much much less promenade inent than before menstruation diarrhea purchase 60mg raloxifene otc. Because the atrioventricular canal enlarges to the best, blood passing via the atrioventricular orifice now has direct access to the primitive left as well as the primitive right ventricle questions menstrual cycle generic 60mg raloxifene with visa. In addition to the dorsal and ventral endo cardial cushions, two lateral atrioventricular cushions seem on the proper and left borders of the canal women's health clinic victoria texas cheap raloxifene 60mg fast delivery. The dorsal and ventral cushions, within the meantime, project further into the lumen and fuse, resulting in an entire divisi�n of the canal into right and left atrioventricular ori�ces by the end of the fifth week. A trioventricular Valves After the atrioventricular endocardial cush ions fuse, each atrioventricular ori�ce is surrounded by native proliferations of mesenchymal tissue derived from the endocardial cushions. At this stage of growth, blood from the atrial cavity enters the prim itive left ventricle in addition to the prim itive right ventrlcle. Finally, muscular tissue within the cords degenerates and is changed by dense connective tissue. They are related to thick muscular trabeculae in the wall of the ventricle, the papillary muscles, by the use of chordae tendineae. In this fashion, two valve leaflets, constituting the bicuspid (or m itral) valve, kind in the left atrioventricular canal, and three, constituting the tricuspid valve, type on the best facet. The valves are hollowed out from the ventricular side however remain hooked up to the ventricular wall by the chordae tendineae. It m ay be caused by excessive cell d ea th and res o rp tio n of th e septum prim u m. On the right, the ventricle may be very small, the pulm onary artery is affected and may be atretic or stenosed and the atrium may be small; on the left, the ventricle could be very small, the aorta may be atretic or stenotic, and the atrium may be reduced in size. The laterality related v/ith these defects suggests an opposed effect on specification of the le ft and right cardiac progenitor cells at an early stage of cardiac morphogenesis. Common atrium, or cor triloculare biventriculare, resulting from full failure of the septum primum and septum secundum to kind. This abnorm ality is always accompanied by a septum defect within the atrial in addition to within the ventricular portion of the cardiac partitions. Ostium prim um defect brought on by incom plete fusi�n of the atrioventricular endocardial cushions. These ridges, the truncus swellings, or cushions, He on the proper superior wall (right superior truncus swelling) and on the left inferior wall (left inferior truncus swelling). The proper superior truncus swelling grows distally and to the left, and the left inferior truncus swelling grows distally and to the proper. Henee, whereas rising towards the aortic sac, the swellings twist around one another, foreshadowing the spiralcourse ofthe future septum. After full fusi�n, the ridges kind the aorticopulmonary septum, dividing the truncus into an aortic and a pulmonaiy channel. When the truncus swellings appear, similar swellings (cushions) develop alongside the proper dorsal and left ventral walls of the conus co r �is. The conus swellings develop toward one another and distally to unite with the truncus septum. When the two conus swellings have fused, the septum divides the conus into an anterolateral portion (the outflow tract of the proper ventricle). Cardiac neural crest cells, originating in the edges of the neural folds within the hindbrain regi�n, migrate via pharyngeal arches 3, 4, and 6 to the outflow regi�n of the guts, which they invade. In this location, they contribute to endocardial cushion formation in both the conus cordis and truncus arteriosus. Proliferations of the right and le ft conus cushions, mixed with proliferation of the anterior endocardial cushion, ci�se the interventricular foramen and kind the membranous portion of the interventricular sep tum. The conus septum Is complete, and blood from the le ft ventricle enters the aorta. In this location, they con tribute to septation of the conus cordis and truncus arteriosus. This is achieved by steady development of the myocardium on the skin and steady diverticulation and trabecula formation on the within. The medial waUs of the expanding ventricles turn into apposed and progressively merge, forming the muscular interventricular septum.
