Abstract
Transluminal angioplasty during vascular reconstructive procedures was performed to 18 lesions in 13 patients. Ages ranged from 57 to 81 years with a mean of 72.7 years, and all patients were men. Transluminal angioplasty during the thromboendarterectomy or bypass grafting was performed to 3 patients for inflow dilatation, 3 patients for outflow dilatation and 1 patient for renal artery dilatation. Transluminal angioplasty with thrombectomy for the anastomotic stenoses of EPTFE grafts was performed 11 times for 7 patients. The results of this method for arteriosclerotic lesions were as follows; patency was 100% at 1 year and 80% at 3 year. Four patients died during the follow-up periods and the dilated lesions were all patent at the time of death. The results of this method for anastomotic stenoses were as follows; patency was 34.6% at 6 month and 0% at 10 months. Graft infection occurred in 1 of 4 patients to whom transluminal angioplasty was performed 2 times. The patency of transluminal angioplasty during vascular reconstructive procedures for arteriosclerotic lesions was good. Transluminal angioplasty for anastomotic stenoses was noninvasive and easily performed with the thrombectomy, but the patency was not so good and there was the risk of graft infection by repeated operations.
