Summary
In this anomaly, observed in the right pelvic region of a female newborn cadaver among 100 studied (1%), a common arterial trunk arose from the medial side of the external iliac a. 1 cm proximal to the inguinal ligament. The trunk first divided into an ascending branch, which finally divided into the obturator and inferior epigastric arteries, and a descending branch, the profunda femoris a. from which arose the medial circumflex femoral a. The origin of the profunda femoris, obturator and inferior epigastric aa. is explained on the basis of the embryologic development and their course and variations are compared with reports in the literature.
Résumé
L'anomalie rapportée a été observée dans la région pelvienne droite du cadavre nouveau-né d'une petite fille sur 100 cadavres étudiés (1 %). Le tronc artériel commun naissait de la face médiale de l'a. iliaque externe, 1 cm proximalement au ligament inguinal. Le tronc se divisait d'abord en une branche ascendante, qui se divisait ensuite en aa. obturatrice et épigastrique inférieure, et une autre branche descendante, l'a. profonde de la cuisse, dont naissait l'a. circonflexe fémorale médiale. L'origine des aa. profonde de la cuisse, obturatrice et épigastrique inférieure pourrait être expliquées par le développement embryonnaire. Leur trajet et leurs variations sont étudiés à la lumière de la littérature.
