title: Traumatic aneurysm in persistent sciatic artery.
abstract: A 59-year-old male patient admitted to our hospital with a pulsatile right gluteal mass with history of formation after blunt trauma. Persistent sciatic artery and its traumatic aneurysm was diagnosed after medical examination followed by peripheric digital substraction angiography. Surgery was performed under general anesthesia, and the patient was discharged from the hospital on postoperative day 7 without any problems. The sciatic artery, a continuation of the internal iliac artery into the popliteal-tibial vessels, represents the major blood supply to the lower limb in early embryologic development. Its persistence is very rare, and the aneurysmatic dilatation is the most common pathology diagnosed. Here, we present a rare case of persistent sciatic artery presenting with a traumatic aneurysm treated by iliopopliteal bypass surgery and ligation of the internal iliac artery proximal to the aneurysm.
