Persistent sciatic artery: a case report.
Persistence of the embryonic sciatic artery is a rare vascular anomaly with only 52 documented cases, of which only 19 had angiographic studies. We describe a patient with angiographic demonstration of persistence of a left sciatic artery associated with arterial anomalies of the opposite limb. The embryology radiological findings and clinical significance are discussed.
