The role of coronary bypass surgery for single vessel disease is still controversial. A comparative study was made on the results of bypass surgery in 22 cases. Seventeen had proximal lesion in LAD was performed in 11 cases (10 LAD and 10 RCA) without death. Primary success was obtained in 8 cases (73%). No major complication was encountered. Emergency bypass operation was not required in any case. Three patients who failed to have successful PTCA subsequently underwent elective coronary bypass surgery. The average coronary stenosis was reduced from 72%-24% in successful cases. Post-PTCA evaluation including treadmill test, coronary sinus flow study and 201Tl scintiscan revealed the effectiveness of this procedure. PTCA is an alternative therapeutic procedure to the more prevalent coronary bypass surgery in selected patients with single vessel disease, if properly performed. Coronary bypass surgery for single vessel disease is also safe and effective if intraoperative coronary spasm can be prevented or managed adequately.
