[Prognostic factors in surgery of ruptured aneurysms of the abdominal aorta]

From 1978 to 1986 83 patients underwent surgery for ruptured abdominal aortic aneurysm. The intraoperative and post-operative mortality rates was 34%. This multivariant analysis has been performed with intention of identifying the specific factors that affected the surgical outcome of ruptured abdominal aortic aneurysms. Increased intraoperative mortality rates were associated with heart disease, while postoperative mortality rates were associated with preoperative hypotension, BUN, levels higher than 40 mg/dl and other factors like duration of operation, blood less, blood transfusion and pre-operative hematocrit.
