A study on internal iliac artery branching pattern and its clinical significance
Abstract
Background: The internal iliac artery is the artery of the pelvis. It supplies most of the blood to the pelvic viscera, gluteal region, medial thigh region and perineum. Injuries of internal iliac artery and its severe bleeding are more common which leads to potentially lethal complication in pelvic surgeries. While operating on pelvic organs, the knowledge of internal iliac artery, its branching pattern and its variations is important for surgeons.
Objectives: The present study conducted to study the branching pattern of internal iliac artery by dissection method and to study the variations in the branching pattern. Materials and
Methods: Dissection of 50 adult human pelvic halves was procured from embalmed cadavers of J.J.M. Medical College and S.S.I.M.S & R.C, Davangere for the study.
Results: The classification of branching pattern of internal iliac artery was based on modified Adachi classification. Out of the 50 specimens studied, Type Ia arrangement was found in 52% of the specimens, Type III in 34%, Type IIa and type V was found in 2% each, Type IV was not found in any of the specimens and 10% of the specimens could not be classified because of the absence of inferior gluteal artery in them.
Conclusion: Adachi Type Ia arrangement was the most frequent finding. The obturator artery took origin most frequently from the anterior division of internal iliac artery. Middle rectal artery was not constant.
