Abstract
A study on internal iliac artery branching pattern and its clinical significance
Highlights
The internal iliac artery is the chief arterial source of pelvis and it is internal division of common iliac artery
In the present study of 50 pelvic halves, the most common site of origin of internal iliac artery was at the level of lumbo-sacral intervertebral disc found in 30 specimens (60%)
The common trunk of internal iliac artery did not give any branch in 22 specimens (44%), gave origin to vertebral branches in 15 specimens (30%), to ilio-lumbar artery in 9 specimens (18%), superior gluteal artery in 1 specimen (2%), lateral sacral artery in 2 specimens (4%), both iliolumbar artery and lateral sacral artery in 1 specimen (2%)
Summary
The internal iliac artery is the chief arterial source of pelvis and it is internal division of common iliac artery. In case of male pelvis it supplies branches to the, medial thigh region, gluteal region, the perineum including erectile tissues of the penis and the clitoris. Knowledge of internal iliac artery and its branching pattern is important for the anatomists and for surgeons, obstetricians and gynaecologists, urologists, vascular surgeons and radiologists. In various surgeries of pelvic organs like rectal malignancies, haemorrhoidectomy, the knowledge of internal iliac artery, its branching pattern and its Manuscript Received: 22nd May 2017 Reviewed: 1st June 2017 Author Corrected: 9th June 2017 Accepted for Publication: 15th June 2017. While operating on pelvic organs, the knowledge of internal iliac artery, its branching pattern and its variations is important for surgeons. Results: The classification of branching pattern of internal iliac artery was based on modified Adachi classification.
