title: Simultaneous operation of off pump coronary artery bypass and abdominal aortic aneurysm repair.
abstract: OBJECTIVE
  Coronary artery disease (CAD) and abdominal aortic aneurysms (AAA) commonly coexist. However, each disease treatment complicates the management of the other. In this study, we evaluate whether a simultaneous operation of AAA repair and off pump coronary artery bypass (OPCAB) would be safe and acceptable, compared with either procedure alone.
  
  
  METHODS
  We retrospectively reviewed all patients who underwent simultaneous AAA repair and OPCAB (AAA/OPCAB, n=18), compared AAA repair alone (AAA, n=239) and OPCAB alone (OPCAB, n=137) from June 1999 to December 2003. There were no significant differences with regard to age or gender, but the AAA/OPCAB group had significantly larger aneurysms (60.6 vs. 53.2 mm) and significantly lower ejection fractions (EF) (54.9 vs. 60.3%).
  
  
  RESULTS
  The patients in the AAA/OPCAB group underwent a significantly longer operative time than AAA, OPCAB (403 vs. 360, 296 minutes, respectively), there was significantly greater blood loss (726 vs. 426, 462 ml), and more transfusion required (8.13 vs. 1.69, 2.8 units). The number of bypass grafts in AAA/OPCAB group (1-5 per patients) was significantly smaller (1.78 vs. 2.93). The AAA/OPCAB patients had a significantly longer hospital stay than the AAA (38 vs. 22 days), but was not significantly longer than the OPCAB. There were no significant differences with regard to the morbidity and mortality rate among the three groups.
  
  
  CONCLUSIONS
  This study suggests that the simultaneous operation of AAA and OPCAB can be done with the same morbidity and mortality as independent surgical procedures.
