[Clinical study of continuous warm blood cardioplegia with normothermic cardiopulmonary bypass in coronary artery bypass surgery].
This study was undertaken to determine whether continuous warm blood cardioplegia (CWBCP) could be acceptable as an alternative method for myocardial preservation in cardiac surgery. Between December 1991 and June 1993, 100 consecutive patients underwent coronary artery bypass surgery. Four patients who received terminal warm blood cardioplegia were excluded in this study. ⋯ Group W patients were more likely to be hemodynamically stable after CPB discontinuing. Serum potassium levels during CPB was higher in Group W (max. 5.67 +/- 0.96 versus 4.39 +/- 0.50 mEq/l), so excessive potassium was eliminated using extracorporeal ultrafiltration. The major drawback of CWBCP was that continuous coronary perfusate occasionally obscured anastomosis site.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[A two staged extending graft replacement for dissecting aortic aneurysm with Marfan's syndrome].
We experienced four cases of dissecting aortic aneurysms with Marfan's syndrome, in which two staged operations were performed with satisfactory results. The operations performed in the four patients were the replacement of the ascending aorta, transverse aortic arch and the entire descending thoracic aorta in DeBakey type I dissecting aortic aneurysm, replacement of the entire descending thoracic and abdominal aorta in type IIIb, replacement of the aortic valve, ascending aorta, transverse aortic arch, the entire descending thoracic and upper abdominal aorta in type I, and replacement of the total aorta including the aortic valve in type II + IIIb, respectively. ⋯ Dissecting aortic aneurysm with Marfan's syndrome must be observed carefully and corrected surgically, because the lesion is progressive and the residual dissecting aneurysm usually dilates eventually. In view of our clinical results, we conclude that the operation for dissecting aortic aneurysm with Marfan's syndrome should be performed as extensively as possible.
