Impact of organ malperfusion on mortality and morbidity in acute type A aortic dissections.

Background: Organ malperfusion is a serious complication of acute type A aortic dissection. Management and outcome of malperfusion has been discussed in this study.

Methods: Between November 1994 and May 2003, 118 patients with acute type A aortic dissections were operated.

Prophylactic dialysis in patients with renal dysfunction undergoing on-pump coronary artery bypass surgery.

Background: Preoperative creatinine values higher than 2.5 mg/dL are associated with markedly increased risk for both mortality and morbidity in patients undergoing coronary artery bypass surgery. We aimed to determine the effects of prophylactic perioperative hemodialysis on operative outcome in patients with nondialysis-dependent moderate renal dysfunction.
