Evaluation of factors influencing survival in ruptured aortic aneurysms

During the six year period ending in December 1986, 103 patients with ruptured abdominal aneurysms presented to the unit. Ninety-two patients underwent surgery with a mortality of 39%. There was an increase in mortality with preoperative risk factors, extent of surgery, prolonged stay in ICU, complications and amount of blood transfused. However, only the latter was statistically significant. Age, the distance traveled by the patient before arrival at the hospital, systolic blood pressure on presentation and duration of operation did not affect the mortality.
