Surgical Treatment of Abdominal Aortic Aneurysm in Cases with Previous Laparotomies / 日本心臓血管外科学会雑誌

ABSTRACT

From January 1987 to October 1992, 60 consecutive patients operated on for infrarenal abdominal aortic aneurysm (AAA) were reviewed to evaluate the effect of previous laparotomies giving on the results of aneurysmal surgery. Eleven of 60 patients had previous laparotomies. Two of them required emergency operation for ruptured aneurysms. One of them died during surgery as a result of excessive hemorrhage prior to cross-clamping the aorta. Severe peritoneal adhesion had made if difficult to properly expose the aorta for cross-clamping to control hemorrhage. There were no statistical significance in mortality between the previous laparotomy and non-laparotomy groups. Excluding ruptured cases, we compared the previous laparotomy group (9 patients) and non-laparotomy group (37 patients) with reference to perioperative factors, including operation time, blood loss, non-oral feeding days, bed-ridden days, and hospital stay but there were no statistically significant differences. These results suggested that previous laparotomy is not a serious risk factor in operations for AAA.
