Exclusive Y graft operation for multivessel coronary revascularization

Abstract

Background. The pedicled (in-situ) left internal mammary artery grafted to the left anterior descending artery has a very high late patency and reduces late mortality following coronary artery bypass surgery. A technique is described which achieves total arterial revascularization in patients with multivessel coronary disease and which is also entirely pedicled. Methods. Using the left internal mammary artery and radial artery joined as a composite Y graft, all coronary territories may be grafted. Results. One in-hospital death from 464 patients (0.2%) occurred. Age (mean ± standard error) was 64.7 ± 0.5 years and number of distal anastomoses 3.4 ± 0.04. Of 1,681 patients from Royal Melbourn..
