Bilateral branching variants ofinternal and external iliac arteries

ABSTRACT

During a routine female cadaveric dissection, we found an unusual bilateral pelvic branching pattern of the internal and external iliac arteries. The vaginal and middle rectal arteries had a common origin from the right internal pudendal artery. An aberrant obturator artery arises from both external iliac arteries. A right aberrant obturator artery gives a small branch to the back of the pubic bone. The left inferior epigastric artery arises from the common trunk of the external iliac artery with the aberrant obturator artery. Knowledge of arterial variations helps to reduce the internal hemorrhage during abdominal and pelvic surgeries
