The Persistent Sciatic Artery (PSA) is a rare congenital anomaly due to missed involution of embryo-fetal sciatic artery, which is the main blood supply to lower limb during embryonic development until superficial femoral artery (SFA) is formed. The PSA is frequently related to complications in adults like aneurysm and embolism. Here we present a case in which the discovery of a complete PSA resulted limb saving. In case of oncologic or trauma surgery, when no other options are available, the PSA can help in management of reconstructive surgery.

Abstract

The Persistent Sciatic Artery (PSA) is a rare congenital anomaly due to missed involution of embryo-fetal sciatic artery, which is the main blood supply to lower limb during embryonic development until superficial femoral artery (SFA) is formed. The PSA is frequently related to complications in adults like aneurysm and embolism. Here we present a case in which the discovery of a complete PSA resulted limb saving. In case of oncologic or trauma surgery, when no other options are available, the PSA can help in management of reconstructive surgery.
