An asymptomatic persistent sciatic artery in SACRAL syndrome: About a case in ultrasonography

We report a rare case of an asymptomatic persistent sciatic artery (PSA) detected on Doppler ultrasonography (DUS) in a boy with SACRAL syndrome. We describe the natural course of PSA and emphasize the importance of repeated DUS, which is the preferred imaging modality by vascular physicians, in identifying anatomical features and variations in malformative syndromes.
