Incidental Finding of Complete Bilateral Persistent Sciatic Arteries

Abstract

Persistence of bilateral sciatic arteries (PSA) is a rare congenital vascular anomaly. We report an exceptionally rare case of complete bilateral persistent sciatic arteries, diagnosed incidentally on computed tomography angiography (CTA) in a young female patient who sustained a gunshot wound to the lower limb. The embryology, variants, clinical and imaging findings, potential complications, and treatment options are discussed. PSAs, found incidentally, are unlikely to have clinical significance, however, the unusual anatomy and higher incidence of future complications requires accurate reporting of such variants.
