Percutaneous transluminal angioplasty of stenotic saphenous vein right coronary bypass grafts utilizing a peripheral balloon dilatation catheter without a guiding catheter.
Effective angioplasty of stenosed saphenous vein coronary bypass grafts may be impossible with the standard-size coronary dilatation catheters because the large diameter of these grafts results in unacceptable balloon-to-vessel ratios. We avoided this problem by using a peripheral arterial dilatation catheter with an inflation diameter of 6 mm and obtained a satisfactory short- and long-term result in two patients in whom previous attempts with the largest coronary dilatation catheter (4 mm) had failed. This technique, which precludes the use of a guiding catheter, is suitable only for right bypass grafts.
