Variations of anterior and posterior division of internal iliac artery: A systematic review and clinical implications

Abstract

The distribution pattern of internal iliac artery (IIA) implies its bifurcation to two branches, the anterior and the posterior trunks. According to previous research, IIA indicates several anatomical variations. The purpose of this study is to evaluate the types of these variations. The presence of these variations in the arteries is an important topic to urologists, gynecologists, radiologists, and general surgeons because they can be ruptured during surgical procedures in the perineal and pelvis region. Three databases were searched for the period from 1810 to January 2018 and a total of 75 studies were investigated. This study evaluated the branching of the internal iliac artery in several literatures and compared it with Adachi's classification. This finding can lead to improve surgical technique and safety in medical practice.
