The influence of the deep femoral artery on wound healing in amputees.

Seventeen patients with arterial occlusive disease, of whom 14 were diabetics, were studied by angiography after amputation of the lower extremity. In one patient the angiography was normal and the stump wound healed well. In two patients the angiographic findings indicated extremely severe impairment of blood supply and wound healing was considerably delayed. Of the remaining 14 patients: in five the superficial femoral artery alone was occluded and wound healing was normal and in nine patients, both the superficial and deep femoral arteries were occluded and wound healing was delayed. Wound healing of the stump after amputation of the lower extremity due to extensive arterial occlusive disease is decided by the patency of the deep femoral artery.
