Salvage of replanted parts of the upper extremity.

Twelve patients with fifteen replanted parts had vascular exploration in order to salvage the replantation after impending failure developed. Arterial occlusion only was found in eleven parts, while arterial and venous occlusion was found in the other four. Vein grafts were used in ten parts, with success in eight. Thrombectomy was done in six, with success in only one. It was possible to salvage nine of the fifteen replanted parts. The best results were obtained when the revision was done within eleven hours after the replantation.
