Bypass aorto coronarico circolare: risultati immediati ed a distanza.

At Cardiovascular surgery department of Parma, from January 1984 through December 1985, myocardial revascularization with aortocoronary circular sequential vein graft technique was performed in 48 patients with severe and diffuse coronary stenosis and with saphenous vein with large caliber. There were no operative deaths, bypass/patient ratio was 5:1 and 6 patients underwent combined cardiovascular surgical procedures. The incidence of perioperative myocardial infarction was 4,1%. At mean follow-up interval of 37,35 mounths (ranging from 21 to 46) survival rate was 93,8% (1 non cardiac death occurring) and 4 patients (8,8%) had anginal recurrence medically treated. We concluded that in patients with clinical and perioperative features such as large saphenous vein, multiple distal coronary lesions, the aortocoronary circular bypass technique is indicated; moreover, because of its dependency on single proximal aortic connection this procedure should not been considered as an alternative method of myocardial revascularization, but can be used in selected coronarographic and intraoperative cases.
