Bilateral IMA grafting was associated with greater drainage and reoperation for bleeding; leaves open net benefit versus unilateral use in CABG.
Does bilateral IMA grafting increase the complication rate, especially pleural problems, compared to unilateral IMA grafting in patients undergoing coronary bypass surgery?
Bilateral IMA grafting increases bleeding and reoperation rates compared to unilateral grafting, but does not cause excessive pulmonary complications.
Aarnio et al. (1991) studied this question.
