Risk Factors Of Postoperative Mortality Of Ruptured Abdominal Aortic Aneurysm:a Retrospective Study

Purpose:Through a retrospective study of4General Hospital in14years of ruptured abdominal aortic aneurysm (ruptured abdominal aortic aneurysm RAAA) in patients with clinical data, discusses influence of this kind of patients with postoperative death related risk factors, thus to reduce mortality postoperatively in patients with ruptured abdominal aortic aneurysm and to Standard diagnosis and treatment is of great significance.Methods:Between January1999and December2012, retrospective review of76patients with open repair of RAAA. In this study. Postoperative patients with ruptured abdominal aortic aneurysm can be divided into death and survival group classification research. The risk of postoperative death related factors can be divided into preoperative, intraoperative and postoperative on univariate analysis. The factors considered preoperatively include age, gender, smoking, serum inosine clearance, hemoglobin measurement, shock, the emergency to the operating room time. Factors considered Intraoperatively include blood loss, blood transfusion amount, the position of the aorta blocking and time, location characteristics of aneurysm, broken parts, urine output per hour, and operation time. Postoperative factor include the inotropic support, artificial kidney dialysis, intestinal ischemic necrosis, multiple organ failure, and the time duration of the intensive care ward. Finally, related factors of postoperative death of ruptured abdominal aortic aneurysm to multivariate analysis.Results:(1) This research object mortality was52.63%.(2) On the univariate analysis, smoking,Serum inosine clearance, shock, blood transfusion amount, urine output per hour, renal replacement therapy, intestinal ischemic necrosis, multiple organ failure for postoperative mortality were statistical significant (P <0.05).(3) In the multivariate analysis, smoking, serum inosine clearance, shock, for postoperative mortality were statistical significance (P<0.05).Conclusion:(1) This research object mortality was52.63%.(2) Risk factors for ruptured abdominal aortic aneurysm patients of postoperative mortality is smoking, serum inosine clearance, shock.
