This study was designed to evaluate
the optimal surgical treatment strategy for abdominal aortic
aneurysm (AAA) coexisting with coronary artery disease (CAD).
Twenty-six patients (21 men and 5 women with a mean age of 72.6±3.7years
old) who required surgical treatment of both conditions were
examined. Eleven patients underwent a one-stage operation. Four
of them had on-pump CABG and 7, including 3 high-risk-patients,
underwent off-pump CABG. There were no operative mortalities,
but 3 patients had severe morbidity (respiratory failure, acute
renal failure, pneumonia). Fifteen patients underwent a two-stage
operation. None of them had rupture of the AAA during the interval
between the two operations, but 2 patients with large AAA (more
than 6cm in diameter) required emergency operation due to impending
rupture of the AAA. There was no operative mortality, but one
patient suffered acute renal failure. One-stage operation for
low-risk patients seems to be a safe and reasonable strategy.
One-stage operation for high-risk patients should be performed
cautiously, and off-pump CABG is especially useful in such patients.
