The frontal branch runs toward the midline of the forehead above the eyebrow, and the parietal branch
supplies the parietal region (Fig.
The anterior division gives rise to vesical, uterine, vaginal, and middle rectal arteries (visceral branches), obturator, inferior gluteal and internal pudendal arteries (parietal branches
It was also interesting to note the anomalous origin of the obturator artery from the posterior division in 6.8% of cases , as the parietal branches
of the obturator play an important role in collateral circulation.
The middle trunk divided into the angular, central, and anterior parietal branches
on one side and posterior parietal and temporal occipital on the other side.
The parietal branches
secured are the obturator artery, the inferior gluteal artery and the internal pudendal artery.
The parietal branches of the anterior division are obturator artery (OB), inferior gluteal artery (IG), and internal pudendal artery (IP).
The parietal branches were traced till their exit from the pelvic cavity.
The parietal branches of OB are important collaterals in aortoiliac and femoral arterial occlusive diseases.
SUMMARY: Obturator arteryis frequently a branch of anterior division of internal iliac artery or one of the parietal branches of internal iliac artery.
The parietal branches of OBA are important collaterals in aortoiliac and femoral arterial occlusive diseases.
