[Renal artery vascularization in the African black. Report of 44 dissections].

Studies on the anatomy of the renal arteries in Black Africans being scarce, the authors have made their contribution to the knowledge of the renal arteries. They have provided a comparison between the anatomy of the renal arteries studied in the literature in relation to a white patient and black patient. It is a prospective study based on the change in the number of the renal arteries of 44 Black Africans' maccabees quite fresh, not yet embalmed that have been dissected in order, as received in the anatomy laboratory of Abidjan. That work has allowed to notice some results that are more or less similar to those revealed in the literature, i.e. in 80% of the cases, the kidney is irrigated by an artery, and in 20% of the cases, we have more than one artery for one kidney. No kidney is vascularized by more than two arteries. These results underline how important it is to have good anatomical knowledge of this region in renal surgery. This is possible thanks to medical imagery and arteriography which helps in preventing operative accidents and in preserving the kidney.

[Internal iliac artery: functional anastomosis value and pelvic surgery application].

The vascularization of the intra and extra pelvic organs of adults, children and neonates (male and female) is studied in 17 pelvis, in which the vascular system has been injected with colored Altufix p10 and gelatinous india ink. The pelvic region constitute a true vascular crossroad of two anastomotic networks, one arterial, originate from the visceral and parietal branches of iliac internal and external arteries, femoral and abdominal aorta by inferior mesenteric artery; the other one, which morphology is incompletely superposable in diameter. Each organ is tributary of characteristic vascular system from adventitious to mucosa with direct or recurrential manner between striated muscle fibers and mucosal layers. This duality of two systems, vascular and anastomotic provides the anatomic direction of vascular suppliance after troncular iliac artery binding and determines the vitality of the organ.

[Sinus node vascularization in the black African].

The aim of this study is to identify in 43 adults African hearts the different arteries of the sinus node. The method used is the injection corrosion technic of the coronary vessels. This study conclude that the right coronary system is the principal way of irrigation of sinus node in Africans (46.6% of cases).

[The left renal retro-aortic vein: report of three cases].

This study investigated the congenital retro-aortic left renal vein in three subjects, observed in dissection practice. Comparative morphometric analysis is made about vein and artery and their collaterals. The importance and the contribution of this left retro-aortic renal vein are discussed with reference to his embryologic and clinical aspect implication.

[The musculo-fascial graft from the elevator muscle of the anus. Importance for plastic surgery of the bladder in the treatment of obstetric vesico-vaginal fistulas].

The levator ano-muscle and fascia are studied by females pelvis. The muscle is composed of three groups of fibres: the puborectalis muscle, the ilococcygeus and the ischiococcygeus muscles. The muscular fascial graft is dissected from the superior fibers of puborectalis muscle and placed in front of the lateral face of the bladder. In this regard, the anatomical and clinical knowledges are provided and morphometric and morphologic studies proposed this graft as the inter-vesico-vaginal plasty in treatment of vesico-vaginal fistulae.

[Coronary veins and coronary sinus tributary veins in Africans].

This anatomical study carried out on 40 African adults hearts studied branches of the coronary sinus. By using of injection of the coronary arteries and corrosion of the myocardium, the study identified certain peculiarities of the small coronary vein and the posterior descending interventricular vein in Africans.
