Aneurysms of the persistent sciatic artery.
The persistent sciatic artery is a rare anatomical anomaly of the lower limb vasculature. It may be noted incidentally, or it may present with limb ischaemia or aneurysmal degeneration. Management entails exclusion of the aneurysm and vascular reconstruction. A case of bilateral persistent sciatic artery aneurysms and a review of the embryological development, clinical features, and management are reported. The persistent sciatic artery (PSA) may result from an aberration in the development of the arterial supply to the lower limb. It is a rare anomaly, with sporadic cases reported in the literature, few of which have been angiographically documented. A report of a patient treated at King Edward VIII Hospital, Durban, is presented here.
