Summary
The present work deals with a study of the supraduodenal a. in 30 specimens. It was present in 28 cases: when absent it was substituted by the right gastric a. Its origin is discussed, the most frequent being the gastroduodenal a., with 2 cases in the pericholedochal plexus. Distribution to the distal two thirds of the upper portion of the duodenum was constant, extending to the supra- and retroduodenal portions of the common duct. Its anastomosis with the gastric right a. and the posterior superior pancreaticoduodenal a. was established in half the cases, being more frequent with the former.
Résumé
Ce travail rapporte les résultats d'une étude de l'a. supraduodénale effectuée sur 30 dissections cadavériques. Présente 28 fois sur 30, elle est remplacée par l'a. gastrique droite lorsqu'elle manque. Son origine n'est pas constante: elle naît dans la plupart des cas de l'a. gastroduodénale, mais dans 2 cas elle provient d'un plexus péricholédocien. Elle s'anastomose dans la moitié des cas avec l'a. gastrique droite et moins fréquemment avec l'a. pancréatico-duodénale postérieure et supérieure.
