Abstract

Internal iliac artery (IIA) is one of the terminal branches of the common iliac artery and is the prime artery of pelvis. The artery has many parietal and visceral branches and hence the variations are frequently noted. The larger branches, namely, the inferior gluteal artery, the superior gluteal artery, and the internal pudendal artery, show sufficient regularity in their patterns of origin to allow typing. The variability of the IIA and its branching pattern were studied by dissecting sixty-eight male pelvic halves (34 right and 34 left) and forty-eight female pelvic halves (24 right and 24 left sides). In significant number of specimens, IIA terminated without dividing into 2 trunks as against the usual description. There was also considerable interchange of branches between the 2 terminal divisions. The patterns of branching noted were grouped as per Adachi's classification. The incidence was noted to be as follows: type Ia in 60.6%, type Ib in 2.6%, type IIa in 15.8%, and type III in 21%. The other types were not observed in this study. Conclusion. Interventions in the pelvic region must take into account the variability of the IIA and its branches that can modify the expected relations and may lead to undesired hemorrhagic or embolic accidents.

Highlights

I recently came across an interesting and useful article on “Variability in the Branching Pattern of the Internal Iliac Artery in Indian Population and Its Clinical Importance,” by Sakthivelavan et al [1]
Despite the fact that this procedure is mostly done as an emergency, it still requires the surgeon to have a thorough understanding of the anatomy to prevent iatrogenic injury and to have adequate hemostasis
It was interesting to read about the different anatomical variations of the iliac artery (IIA) in the Indian population

Summary

Introduction

I recently came across an interesting and useful article on “Variability in the Branching Pattern of the Internal Iliac Artery in Indian Population and Its Clinical Importance,” by Sakthivelavan et al [1]. Hemorrhage is one of the common causes of maternal deaths in the developing nations [2, 3]. Pelvic hemorrhage is a major cause of morbidity and mortality in gynecological surgeries [4].
