The persistent sciatic artery is a rare anatomical anomaly of the lower lim
b vasculature. It may be noted incidentally, or it may present with limb is
chaemia or aneurysmal degeneration. Management entails exclusion of the ane
urysm and vascular reconstruction. A case of bilateral persistent sciatic a
rtery aneurysms and a review of the embryological development, clinical fea
tures, and management are reported.
The persistent sciatic artery (PSA) may result from an aberration in the de
velopment of the arterial supply to the lower limb. It is a rare anomaly, w
ith sporadic cases reported in the literature, few of which have been angio
graphically documented. A report of a patient treated at King Edward VIII H
ospital, Durban, is presented here.
