[Postoperative complications of abdominal aortic aneurysm--with special reference to postoperative renal hypofunction].
Effects of various factors before and during operation on postoperative renal hypofunction were studied in 34 preoperatively evaluated surgical cases of non-ruptured abdominal aneurysm. The cases were divided into two groups, with and without postoperative renal hypofunction. The two groups showed no differences with respect to age, sex, preoperative serum Crn or Ccr level, presence or absence of treatment with antihypertensives or diabetes mellitus, duration of intraoperative aortic clamping, or the volume of blood loss or transfusion. However, the group with postoperative renal hypofunction included many cases of preoperative hypertension. The incidence of postoperative renal hypofunction was high among cases which exhibited preoperative hypertension, but was low among those with preoperative normal blood pressure. Further, renal hypofunction occurred in few of the patients whose blood pressure had been controlled by the use of antihypertensives. The possibility was suggested that in palliative operations, preoperative blood pressure control, was useful for the prevention of postoperative renal hypofunction.
