Abstract
In a series of 65 free composite tissue transplantations by means of microsurgical techniques, 37 transplantations were performed to recipient sites in the lower extremity in 34 patients. Twenty-eight of these patients with 31 composite transplants were examined by femoral arteriography to assess the patency of 33 arterial anastomotic lines 6-45 mo., median 12 mo., postoperatively. Angiography showed patency in 32 of 33 arterial anastomotic lines, 1 arteriography being inconclusive. Apparently, microsurgical techniques in small vessel anastomosis (ext. diam, 0.75-3.50 mm) are essential prerequisites for long-term vascular patency.
