Rare vascular anomaly, the persistent sciatic artery (PSA) has an extremely low incidence, likely 0.04%-0.06%. This vessel is prone to thrombosis, distal thromboembolization, rupture, and aneurysmal formation, while its symptoms can vary considerably, from completely asymptomatic pictures to cases with pain, claudication or ischemia of the lower limbs. It is essential to diagnose this anomaly in time, in order to avoid dangerous complications for the patient's life. The main methods of diagnosis are given by vascular ultrasound, CT, or MRI. Here we present a case of a bilateral PSA diagnosed in a 77-year-old woman as an incidental finding in angio-CT of the lower limbs.
