This retrospective study was performed to identify the perioperative factors affecting the mortality rate in 28 patients, who had received emergency surgery for ruptured abdominal aortic aneurysms from January, 2005 to June, 2008. Five (17.9%) of these 28 patients died of massive bleeding, sepsis, or multiple organ failure during or within 11 days after surgery. Various factors which might influence the outcomes were compared between the survivors and non-survivors. Preoperative hypotension defined as a systolic blood pressure < or = 80 mmHg associated with hemorrhagic shock was the only significant factor affecting the mortality. There were no significant differences in age, gender, the time from the admittance to the hospital to aortic cross clamping, duration of surgery, and the amount of blood products transfused and intraoperative blood loss, between the two groups. Of great importance is that preoperative hypotension should be corrected before the onset of hemodynamic deterioration.
