Management of severe ischemia of the foot secondary to occlusive vascular disease.
One hundred patients, 111 limbs, with gangrene of the lower extremity were initially treated with lumbar sympathectomy. Lumbar sympathectomy appears to be most beneficial in the management of gangrene of the toe with a limb salvage rate of 75 per cent. The best results were seen when only one toe, not the big toe, was involved. Limb salvage dropped to 38 per cent for gangrene of the foot, and with gangrene of the leg, lumbar sympathectomy had no affect. The presence of diabetes had no affect on limb salvage for gangrene of the toe but did have an apparent affect on limb salvage for gangrene of the foot. Sympathectomy appeared to aid in stump healing, with 77 per cent of the amputations done not requiring revision to a higher level. Results of our experience appear to indicate that, for patients presenting with gangrene of the toes or forefoot who are not candidates for reconstructive arterial procedures, lumbar sympathectomy as an initial operative procedure should be given serious consideration.
