A case treated with repeat percutaneous translu-minal coronary angioplasty (PTCA) for recurrent aorto-coronary bypass graft stenosis was reported.

A 52-year-old woman with effort angina pectoris underwent aorto-coronary bypass with a sequential saphenous vein graft to the left anterior descending artery and second diagonal.

Recurrent angina occurred 4 months after operation and coronary arteriography revealed multiple steno-tic lesions in the bypass graft. PTCA was performed and stenose were successfully dilated.

3 months after the first PTCA, a long segment stenosis was found in the bypass graft. Repeat PTCA successfully dilated the lesion. However 2 months after the second PTCA, the bypass graft was com-pletely occuluded at the site of aortic anastomosis.

In this case, the bypass graft was finally occuluded in spite of repeat PTCA. But recurrent angina and ST depression in an exercise ECG due to graft stenosis were markedly improved by PTCA for the graft being safely performed.

PTCA for aorto-coronary bypass graft stenosis is considered to be a safe and effective therapeutic procedure.
