Abstract

Reoperation on the recurrent aortic aneurysm adjuvent to sternum remains a challenging problem in regard to the risk of the massive hemorrhage at the time of resternotomy resulting from inadvertent entry into the aneurysmal sac. The cardiopulmonary bypass technique of femoral cannulation and deep hypothermic circulatory arrest can provide a safe resternotomy. The left ventricle is likely to distend due to lack of contraction with ventricular fibrillation during core cooling. To prevent ventricular distention during core cooling, sufficient venous drainage is mandatory. We report a technique in which deep hypothermic circulatory arrest is achieved before resternotomy without left ventricular distention by active venous drainage using centrifugal pump.
