Unilateral Versus Bilateral Cerebral Perfusion for Acute Type A Aortic Dissection

As one of the largest single-center studies of the efficacy of u-ACP and b-ACP in patients with type A aortic dissection, operative mortality, stroke, temporary neurologic dysfunction, and renal failure rates were similar in both. In this intrinsically complex disease, survival is the most important outcome; u-ACP may provide cardiac surgeons with valuable technical simplicity during challenging procedures, and b-ACP may be justified for circulatory arrest times of more than 30 minutes.
