A rare case of combined bilateral persistent sciatic artery with unilateral pseudoaneurysm

Persistent sciatic artery is a very rare vascular development anomaly with prevalence of 0.03-0.06% based on angiography. Majority of these patients are asymptomatic and usually present due its complications such as aneurysmal dilatations, thrombosis & distal thromboembolic phenomena. We report a case of 50 years old women who presented with swelling and pain in left gluteal region. CT angiography and ultrasound showed, bilateral PSA, complete on left side and incomplete on right side with pseudo-aneurysm on left side. She was managed successfully by endovascular stenting and is under regular follow up.
