Peripheral arterial insufficiency. Experiences from 229 operated limbs

The results of arterial reconstructions in 229 limbs in 177 patients were studied. Intermittent claudication resistant to physical training was indication for surgery in 82 cases and threatening gangrene in 147 cases. In the claudication group the long-term result was good in 77%, the reocclusion frequency was 21%, and the amputation rate was 2%. No operative mortality was encountered. In the gangrene group the long-term result was good in 40%, the reocclusion freuqency was 25%, the amputation rate was 24%, and theoperative mortality was 11%. Limb salvage rate was 65%. The results indicated that preoperative physical training did not jeopardice the operative results, but in most cases made surgical treatment unnecessary. In cases with threatening or beginning gangrene an aggressive attitude towards vascular reconstruction resulted in a substantial limb salvage.
