Variations in its origin and course can lead to unnecessary exploratory surgery and complications during laparoscopic herniorrhaphy procedures. Aim: The aim of the present study is to observe the variations in the origin and course of Obturator artery. Material and methods: Forty (40) adult human pelvic halves of known sexes were studied to note down the variations in the origin, course and dimensions of Obturator artery. Results: In 39 (97.5%) of the specimens Obturator artery was found to be arising normally from the anterior division of internal iliac artery, were as in one (2.5%) of the specimen it was found to be arising bilaterally from the posterior division of internal iliac artery. Conclusions: A good knowledge about the normal anatomy and the variation in the origin and dimensions of the Obturator artery is essential as it reduces the surgical complications during pelvic surgeries.
