Background: Obturator artery is a branch of anterior division of internal iliac artery. It normally runs anteroinferiorly on the lateral wall of pelvis to the upper part of the obturator foramen and leaves the pelvis by passing through the obturator canal. On its course, the artery is accompanied by the obturator nerve and vein. It supplies the muscles of the medial compartment of the thigh. A severe and potentially lethal complication in pelvic injuries is arterial bleeding commonly involving the branches of the internal iliac artery, namely the lateral sacral, iliolumbar, obturator, vesical and inferior gluteal arteries. A sound knowledge of retro-pubic pelvic vascular anatomy is pivotal for successful performance of endoscopic procedures such as total extra-peritoneal inguinal hernioplasty or laparoscopic herniorraphy.
The context and purpose of the study: This study is an attempt to analyse the origin, course, distribution of obturator artery in pelvis and their clinical implication.
Result: out of 60 formalin fixed pelvic halves 36.6% of the specimens, (26.67% in males and 10% in females) the origin of obturator artery was found to be normal from anterior division of internal iliac artery. About 63.63% from various other sources.
Conclusion: This knowledge of variation in the origin of obturator artery is important while doing pelvic and groin surgeries requiring appropriate ligation. Such aberrant origins may be a significant source for persistent bleeding in the setting of acute trauma. Knowledge regarding the variations of obturator artery is useful during surgeries of fracture and direct or indirect inguinal, femoral and obturator hernias.
