Résumé
Arterialization of the foot veins in patients with ischemic foot usually result in excessive foot edema, wound infection, venous gangrene, long hospitalization duration, and a high rate of amputation. We herein present an improved method of foot revascularization via the superficial venous system by in situ reverse arterialization (ISRA) of the foot venous bed, leaving the distal saphenous side branches open. A 69-year-old patient with toe wet gangrene and end-stage peripheral vascular disease with absence of foot target arteries underwent ISRA procedure, using the great saphenous vein, which was anastomosed end-to-side to the proximal superficial femoral artery. Only proximal saphenous tributaries were ligated until arterial flow reached the pedal superficial veins. Postoperatively, the foot regained normal pulsation over the superficial venous system. The patient did not experience foot edema. On-table subtraction angiography demonstrated arterial flow through the long saphenous and dorsal foot veins, with returned venous flow through the anterior and posterior tibial veins. Methoxyisobutylisonitrile scan conducted 4 weeks postoperatively demonstrated positive oxygen uptake of the pedal muscles, which was absent before surgery.

BACKGROUND
Arterialization of the foot veins in patients with ischemic foot usually result in excessive foot edema, wound infection, venous gangrene, long hospitalization duration, and a high rate of amputation. We herein present an improved method of foot revascularization via the superficial venous system by in situ reverse arterialization (ISRA) of the foot venous bed, leaving the distal saphenous side branches open.
METHODS
METHODS
A 69-year-old patient with toe wet gangrene and end-stage peripheral vascular disease with absence of foot target arteries underwent ISRA procedure, using the great saphenous vein, which was anastomosed end-to-side to the proximal superficial femoral artery. Only proximal saphenous tributaries were ligated until arterial flow reached the pedal superficial veins.
RESULTS
RESULTS
Postoperatively, the foot regained normal pulsation over the superficial venous system. The patient did not experience foot edema. On-table subtraction angiography demonstrated arterial flow through the long saphenous and dorsal foot veins, with returned venous flow through the anterior and posterior tibial veins. Methoxyisobutylisonitrile scan conducted 4 weeks postoperatively demonstrated positive oxygen uptake of the pedal muscles, which was absent before surgery. Electron microscopy of the muscles at the level of the transmetatarsal amputation demonstrated regeneration of muscle tissue with mitosis 6 weeks postoperatively. During 1,000 days of follow-up postsurgery, the flow was reduced and the transcutaneous pO

CONCLUSIONS
This new modified surgical technique of ISRA, in which only proximal saphenous tributaries were ligated in order to prevent high systemic pressure in the foot venous low pressure system, resulted in increased levels of transcutaneous pO
