title: Persistent sciatic artery--a curious vascular anomaly.
abstract: A persistent sciatic artery (PSA) is a rare vascular anomaly not extensively described in the interventional cardiology literature. Because of its vulnerable position, it is associated with a high risk of aneurysm formation, making it prone to thrombus formation with subsequent arterial insufficiency because of distal embolization. We report the case of an 80-year-old woman who was found to have bilateral PSA with unilateral aneurysm and evidence of possible distal embolization on conventional angiography.
