The poor long-term results of conventional CABG using veins has led to the use of arterial grafts, namely the internal mammary arteries and radial artery. However, these techniques are more demanding and render the CABG procedure more sophisticated. This prospective study aimed to assess the short term results of CABG using bilateral internal mammary arteries and the risks versus the benefits. Sixty patients were involved in our study and were divided into 2 equal groups. Group (A): CABG using single IMA + other grafts. Group (B): Bilateral IMA + other grafts. Our study was focused on the early outcome regarding in-hospital stay and the incidence of complications including bleeding, reopening, sternal dehiscence, perioperative MI, ATN, AF. The mean age was 58 years in group A and 52 years in group B. There were no statistical significant differences regarding incidence of bleeding, sternal dehiscence or MI.. There was no mortalities among the 2 groups. However, the cross-clamp time was longer in group B. We found that CABG using bilateral IMA does not increase the early mortality and morbidity rates after CABG operation.
