[Surgical treatment of Prinzmetal variant angina. Coronary artery by pass and plexectomy (author's transl)].
Aorto-coronary by pass, widely accepted in the treatment of patients with coronary artery disease is still controversial in the treatment of Prinzmetal variant angina. Recurrence of attacks, occlusion of grafts and post-operative infarction were frequent by described and seem to be related with the persistence of coronary spasm. Authors propose the association of myocardial revascularization and coronary denervation by resection of periaortic plexi. Results of 50 surgical plexectomies associated with coronary by pass appear far better than by pass alone (mortality 4%, myocardial necrosis 4%, persistence of attacks 4%).
