Abstract
Since the variety of arteriosclerotic diseases has increased and the average lift-span has been prolonged in recent years, surgical cases of abdominal aortic aneurysm have increased in number. Surgery, however, is still believed to be contraindicated in many high risk cases. By virtue of marked progress in surgical techniques as well as improved management before, during and after operation, surgery is becoming more and more acceptable, with expected mortality being not more than 5 percent. However, the mortality rate in high risk patients is about 10 percent; the mortality rate for rupture cases is high, and it is given as more than 60 percent in many reports. We recently performed surgery on 4 high risk cases of abdominal aortic aneurysm involving rupture, renal insufficiency, pulmonary emphysema and advanced age. One case ended in death, and postoperative complication with ileus and subdural hydrops appeared in 2 cases. Details are reported here.
