Abstract and Introduction Abstract Persistent sciatic artery (PSA), a persistent embryologic continuation of the internal iliac artery, represents a rare yet clinically important vascular anomaly.

Most cases of persistent sciatic artery are clinically silent in the early stages and detected only after patients show symptoms of vascular complication (e.g., aneurysm, embolism or rupture). 2 ...

Persistent sciatic artery is a rare anatomical variant that arises from the inferior iliac artery and normally regresses in favor of the femoral arteries.
