Insights
Combined coronary artery bypass grafting (CABG) and abdominal aortic aneurysm (AAA) repair showed an 11% mortality rate. Poor ejection fraction, prolonged cardiopulmonary bypass, and respiratory failure were linked to higher mortality risks.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Combined coronary artery bypass grafting (CABG) and abdominal aortic aneurysm (AAA) repair is a complex procedure.
- Understanding factors influencing mortality is crucial for patient outcomes.
Purpose of the Study:
- To report the outcomes of combined CABG and AAA repair.
- To identify factors associated with increased mortality in patients undergoing this combined procedure.
Main Methods:
- Retrospective chart review of 26 patients undergoing combined CABG and AAA repair.
- Analysis of patient data from March 1990 to October 1996.
Main Results:
- The study observed a 38% morbidity rate and an 11% mortality rate.
- Nonsurvivors had significantly lower ejection fraction (EF) and longer cardiopulmonary bypass (CPB) times.
- Higher incidence of postoperative respiratory failure was noted in nonsurvivors.
Conclusions:
- Combined CABG and AAA repair effectively prevented postoperative aneurysm rupture and myocardial infarction.
- Poor EF, prolonged CPB, and postoperative respiratory failure are significant predictors of mortality.
Background:
We report here the results of combined coronary artery bypass grafting (CABG) and abdominal aortic aneurysm (AAA) repair and the factors associated with higher mortality following this procedure.
Methods:
The authors performed a retrospective chart review of 26 patients who underwent combined CABG and AAA repair between March 1990 and October 1996.
Results:
No postoperative myocardial infarction or major cardiac complications were noted. A morbidity rate of 38% (n = 10) and mortality rate of 11% (n = 3) were noted. Comparative analysis of nonsurvivors (n = 3) versus survivors (n = 23) revealed the following: ejection fraction (EF) was significantly lower (33% +/- 3% versus 44% +/- 14%, P < 0.05), duration of cardiopulmonary bypass (CPB) was significantly longer (239 +/- 122 minutes versus 141 +/- 54 minutes, P < 0.05), and incidence of postoperative respiratory failure (67% versus 17%, P = 0.001) were significantly higher in nonsurvivors. No differences in mean age, gender distribution, incidence of hypertension or diabetes were noted between the groups.
Conclusions:
Combined CABG and AAA repair protected patients from postoperative aneurysm rupture and myocardial infarction. Poor EF, prolonged CPB, and postoperative respiratory failure were associated with higher mortality.
