Coronary revascularization using bilateral internal mammary artery-experience at the Punjab institute of cardiology

ABSTRACT

Three hundred and eighty four patients were operated from September, 1991, to November 30, 1993. We used single IMA's on 303 patients, Bilateral IMA's on 30 patients and Bilateral IMA with Right Gastro-Epiploic Arterial grafts on one patient. We compared early and late results on these three groups. Group I - Patients with Vein Grafts only, Group II - Patients with Single IMA Grafts, Group III - Patients with Bilateral IMA. Early results did not show much difference between these three groups as far as complications were concerned except, that there was more blood consumption in Bilateral IMA group, i.e. 300 ml, 550 ml and 700 ml respectively for the three groups. As far as late results are concerned, none of the Bilateral IMA patients was re-admitted for recurrence of Angina or any other complications
