Abstract
From April 1987 to March 1990, we performed open heart surgery using extracorporeal circulation in 90 patients (average age, 51.8 years old) and vascular surgery (graft replacement of abdominal aortic aneurysm and surgery for ASO) in 29 patients (average age, 58.1 years old). Among there, 8 patients with open heart surgery (EEC group) and 9 patients with vascular surgery (vascular group) had suffered from renal insufficiency preoperatively. In the two groups, we compared operative mortality, complications and postoperative severity of renal failure. Preoperative renal insufficiency was defined as a serum creatinine level of more than 1.4mg/dl and postoperative renal failure was defined as 2.0mg/dl. There was no significant difference in operative mortality, in postoperative creatinine, Ccr, BUN and serum potassium and in effectiveness of hemodialysis in the two groups. In conclusion, it seems that we should not hesitate to perform cardiovascular surgery with extracorporeal circulation for patients with renal insufficiency or in hemodialized patients.
