Persistent sciatic artery - different facets of presentation.

Abstract

Persistent sciatic artery is a rare congenital vascular anomaly of the lower limb arterial system. The entity is known to swindle surgeons worldwide with its unusual way of presentation. Suspicion remains the key for early diagnosis and treatment primarily depends on the symptomatology of the patient. We intend to report a series of two cases where the surgeons were literally vexed before a diagnosis was made. The report emphasises the need for further evaluation in situations where symptoms and clinical findings are contradictory. Readily available computed tomography angiography confirms the diagnosis and an early diagnosis makes a huge difference in patient outcome.
