[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.

Anatomical study of the variations in innervation of the orbicularis oculi by the facial nerve.

While the divisions of the facial nerve in the face are well known, the innervation of the orbicularis oculi by the different distal branches of the facial nerve is poorly described. To determine which branches of the facial nerve play a role in this innervation, the facial nerve was dissected in 30 fresh cadavers. The innervation of this muscle was in the form of two plexuses, a superior one, most often (93%) formed by the union of the temporal and superior zygomatic branches, and an inferior one, usually formed (63%) by the union of the inferior zygomatic and superior buccal branches. This new mode of innervation explains how, without damage to both plexuses, innervation of orbicularis oculi by the facial nerve remains functional. It also explains the often unsatisfactory results of treatment of primary blepharospasm, and the unusual character of palsies of this muscle in cervicofacial lifts.

[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).

[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.
