Aortocoronary bypass surgery was controversial in the management of variant angina or vasospastic myocardial ischemia. Persistent attacks, periopera-tive infarction, occlusion of the graft or postopera-tive infarction were described and could be explain-ed by a persistent spasm.

In experimental study, the plexectomy including Wrisberg's ganglion did not demonstrate adverse effect on coronary hemodynamics and prevented the left ventricle from coronary spasm induced by Pitressin.

In clinical study, the plexectomy associated with aortocoronary bypass gained good results than by-pass alone in vasospastic myocardial ischemia. The recurrence rate of operative motality was lower (7.3%) and rate of attacks was decreased (2.4%).

These results suggest that plexectomy associated with aortocornary bypass improves the results of surgical treatment in vasospastic myocardial is-chemia with significant sclerotic lesions.
