Bilateral persistent sciatic arteries complicated with chronic lower limb ischemia
Persistent sciatic artery (PSA) is an unusual anatomical anomaly first reported in 1832 ”IJ and was described angiographically by Cowie m in 1960. The sciatic artery is a continuation of the internal iliac artery and serves as the major blood supply for the lower limb bulb in the early embryonic stage, and it normally involutes and is replaced by the iliofemoral artery as the fetus develops. pl The failure to regress, sometimes associated with femoral arterial hypoplasia, and therefore becoming the dominant inflow to the lower extremity is called persistent sciatic artery. ”””PSA is a rare vascular anomaly associated with a higher rate of aneurysm formation or thromboembolic complications causing lower extremity ischemia. |M) we herein report a 15-year-old female patient with bilateral PSA suffering from lower extremity ischemia.
