[Persistent sciatic artery: findings using spiral-CT].
Persistent sciatic artery (PSA), a rare anatomical anomaly, results from lack of regression of the embryonic dorsal axial artery combined with a poorly developed superficial femoral artery. The authors report the case of a 68-year old man presenting with subacute ischemia of the right lower limb. Arteriography showed complete bilateral persistent sciatic arteries. CT scan with 3D reconstructions was helpful to demonstrate the PSA descending along the back of the thigh and to exclude an aneurysmal complication.
