Surgical treatment of abdominal aortic aneurysm. Factors affecting mortality and morbidity

: In this report, based on a 5 year experience, 76 operation were performed electively for intact abdominal aortic aneurysm and 55 were emergency procedure for ruptured aneurysm. Factor affecting mortality and morbidity in the cases are analysed. Three patients died of cardiac causes following elective aneurysm repair, a mortality rate of 3.9%. No patients died of pulmonary causes, renal failure or required dialysis. No patient developed a graft infection, stroke or intestinal ischemia. Mortality rates for surgical repair of ruptured AAA averaged 32% and the principal cause of death is cardiac disease (50%). The second cause is renal failure. Declining of operative mortality for intact aortic aneurysm is related to earlier diagnosis using non invasive methods and correct preoperative study.
