Report of a Rare Variation in Anterior Trunk of Internal Iliac Artery

There are possible variations in the form of internal iliac artery branches. Sufficient information about such variation is likely to be very useful for surgeons and radiologists. Case Report: A rare variation was observed in a routine dissection of a male cadaver in dissection room of the medical faculty. Internal Iliac artery was divided into anterior and posterior trunk. But lateral anterior trunk was divided into only umbilical, inferior vesical and obturator arteries. The other branches of anterior trunk were originated from posterior trunk. Synchronous variety in anterior and posterior trunk of internal iliac artery is rare and by considering this possibility, bleeding during surgery can be avoided.
