[Surgical stress in perioperative period of combined off-pump coronary artery bypass grafting and abdominal aortic aneurysm repair].
OBJECTIVE
It is still controversial whether we should choose simultaneous operation or two-staged operation for patients who need both coronary artery bypass grafting (CABG) and abdominal aortic aneurysm (AAA) repair. Some reports suggest that combined CABG without cardiopulmonary bypass and AAA repair is less invasive than those with cardiopulmonary bypass. We estimated surgical stress of combined off pump CABG and AAA repair (CABG + AAA) in perioperative period compared with simple AAA repair retrospectively.


METHODS
Seven patients (mean 60 years) underwent simultaneous operation of off pump CABG and AAA repair in our institution. We gathered data associated with circulatory, respiratory, renal function, recovery, and so on. We also examined postoperative complication and mortality.


RESULTS
All parameters, except operation time and amount of catecholamine used, were not significantly different between the two groups. There were no operative mortality and only a slight morbidity in CABG + AAA.


CONCLUSIONS
Our findings suggest that careful circulatory management with adequate transfusion and catecholamine use under precise monitoring is necessary during operation, but recovery after surgery, complication, and mortality in this combined operation are almost equivalent to those of simple AAA repair. We suggest that combined operation of CABG and AAA repair can be performed effectively.
