RESUMEN
A 63-year-old man suffered from type A acute aortic dissection associated with descending thoracic aortic aneurysm and coronary stenosis. He was treated surgically 49 days after onset of acute aortic dissection. Deep hypothermic selective cerebral perfusion was carried out for brain protection. It revealed the aneurysm, 51mm in diameter, located just distal to the aortic arch, and an intimal tear of the dissection located posterior wall of aneurysm. The total arch was replaced with 24mm vascular graft and CABG (LITA-to-seg. 8) was carried out. The postoperative course was uneventful and he was discharged on the 18th postoperative day.
RESUMEN
A 66-year-old woman with aortic stenosis and idiopathic thrombocytopenic purpura (ITP) underwent concomitant splenectomy and aortic valve replacement (AVR). High-dose trans-venous gamma-globulin therapy (400mg/kg/day) was performed for five days before surgery. The number of platelet, which was 6.0×10<sup>4</sup>/mm<sup>3</sup> on admission slighty increased to 7.0×10<sup>4</sup>/mm<sup>3</sup> before surgery. The aortic valve was replaced by an ATS 19mm prosthesis using cardiopulmonary bypass. Platelets were transfused postoperatively. Perioperative hemorrhage was moderate, and the postoperative course was uneventful. This was the second case we treated by concomitant cardiac surgery and splenectomy. It was safely performed after high-dose trans-venous gamma-globulin therapy.
