Ruptured abdominal aortic aneurysm.

A total of 131 surgically treated ruptured abdominal aortic aneurysms have been reviewed. Factors affecting morbidity and mortality rates have been analyzed. In our experience very little improvement has occurred in the last 10 years and the question is raised whether a plateau has been reached in the management of this catastrophic disease. Patient selection is not considered to be the key to better results, since some operated patients inevitably die. Improved technique with better, more rapid control of blood loss, especially from venous tears, will continue to yield better results. Eighty-six nonoperative cases have been studied. Diagnostic accuracy is lower than it should be, often leading to delayed surgery or death.
