Comparison of post-operative neurological complications between on-pump and off-pump coronary artery bypass surgery

ABSTRACT

To assess neurological impairment after the off-pump and On-pump techniques in patients with first-time isolated coronary artery bypass graft surgery. One hundred twenty patients undergoing first-time isolated coronary artery bypass graft surgery prospectively at Baqiatallah University Hospital, Tehran, Iran were randomised to the off-pump or on-pump technique. Change in NIHSS score was measured at 30 days postoperatively. The on-pump group showed a significantly greater deterioration in scores than the off-pump group. The incidence of TIA at 30 days postoperatively was 15.3% [9 out of 60] in the on-pump group and 5% [3 out of 60] in the off-pump group. [P=0.05]. The incidence of Stroke at 30 days postoperatively was 3.4% [2 out of 60] in the off-pump group, while no one from off-pump group suffered from stroke. [P=0.05] Off-pump coronary artery bypass graft surgery results in less neurological impairment than the on-pump technique
