Abstract
Since Jan. 1978, 18 patients having segmental occlusive disease of the aorta-coronary saphenous vein graft or native coronary circulation were evaluated. The significantly occluded vessels were restored to relatively normal circulation by percutaneous transluminal dilatation in 10 of these patients with technical failures in 7 patients and the occurrence of a thrombosis during the procedure in 1 other. Successful dilatation occurred in 6 of 7 patients with saphenous vein graft stenosis. Percutaneous transluminal angioplasty of the native coronary arteries in 11 patients resulted in 5 successful dilatations. All dilatation procedures are performed with the use of local anesthesia with an open-heart team standing by. In the event of technical failure or incipient thrombosis with developing infarction the patient is transferred for immediate bypass. Guidelines of the indications for percutaneous transluminal dilatation of the coronary arteries and their saphenous vein grafts were developed. The need for improved instrumentation to broaden these guidelines is discussed. Case histories of 5 patients and a summary table for all 18 patients are provided. Certain inherent complications are discussed but preliminary results are encouraging particularly with regard to stenoses of saphenous vein bypass grafts.
