[Portal vein: variations of its branches (about 32 dissections)].

PURPOSE: The aim of this study is to precise the variations of portal vein branches and also to elucidate anatomic basis of partial hepatectomy. MATERIAL AND METHODS: Thirty-two post-mortem specimens, with ages ranged from one day to sixty-five years in both two sexes, were dissected. Latex and Rhodopas were used for visualizing and drawing the portal vein course and its branches. RESULTS: Nine types of different variations of portal vein branches were observed. Most of cases were similar to those previously reported in literature. But four types must be especially noted, because they were not available in literature. DISCUSSION: this study updates the anatomy of portal vein and its tributaries, and also finds out four types of distribution which must be known by surgeons with regards to partial hepatectomy.

[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).

[Acute nontraumatic limb ischemia].

Twenty four patients (18 males, 6 females, Mean age 50 years) with acute non traumatic limb ischemia were operated on in our institution. The ischemia has been observed after 24 hours in 15 patients (62,5 % versus 7 patients (37,5 %) within 24 hours. The arterial femoral was often (54,1 %) the site of occlusion. Embolism (29,2 %) and thrombosis (54,2 % were the cause of acute limb ischemia. All patients were treated by embolectomy or thrombectomy. The overall mortality was 29,2 % with a limb salvage rate of 45,8 % and secondary amputation rate of 29,2 %. According to our experience, the diagnosis of acute non traumatic limb ischemia is not instituted early and the rate of hospital mortality and morbidity remain high.

Surgical treatment of patent ductus arteriosus (PDA). Analysis of 145 cases operated on in Abidjan (Cote D'Ivoire).

This retrospective study aims to analyse our surgical procedures and our results after surgery of patent ductus arteriosus (P.D.A.) in children. Since 1978 to 1992 we have reported Abidjan Cardiology Institute 145 children operated cases. The average age was 4.7 years, the average weight 16 kg. There was female predominance with a sex ratio of 2.3/1. All patent ductus arteriosus had been confirmed by two dimensional echocardiography (2D echocardiography) and cardiac catheterization. Type 11a of NADAS' Classification was the most frequent (50%). Double or triple ligation supported on teflon felt was the most frequent technique used (86 times ie 59.3%). This technique gave good results in view of the absence of hospital mortality, only 4 cases of ductus "recanalization" supervened, a low rate of ductus arteriosus recurrence patency at long follow up of all patients from one to 10 years (mean 5 years). Double or triple ligation on teflon felt according to Wright procedure seems to be a securising technique alternative in our countries.

[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.
