Persistent primitive sciatic artery.
Angiography revealed persistence of the primitive sciatic artery in two cases. In one, the artery supplied a large arteriovenous malformation, and the profunda femoris artery was absent. In the other, there were associated findings of neurofibromatosis, decreased left lower limb lymphatic vessels, a left subinguinal lymphocele, and absent external iliac and femoral arteries.
