Case 1
A 59-year-old man awakened with severe constant pain in his right lower extremity and applied a belt tourniquet below the knee. He then consulted his family physician, who removed the tourniquet and noted that the extremity was cold with diminished perfusion and neurologic function.
Significant medical history revealed that the patient had been evaluated 4 years before the present illness because of numbness and weakness in the right lower extremity below the knee. Slightly diminished motor and
Embryology
The sciatic artery is a persistence of the embryologic axial artery, a continuation of the internal iliac artery as the major vascular supply to the lower limb bud in the early embryo (Fig. 5).
