Blunt injury of the abdominal aorta.
This review of 27 cases of blunt injury of the abdominal aorta includes 24 cases reported in the literature and three new cases. Automobile accidents were the cause of this condition in 19 patients (70%). Clinical presentation was acute in 70% of the cases, and consisted of either acute arterial insufficiency or an acute abdomen. Intimal disruption occurred in 15 patients (55%) and was the most common anatomic lesion. Atherosclerotic involvement of the aorta was found in ten patients (37%), and in four it contributed directly to the development of this condition. The infrarenal aorta was the most affected segment (92%). The mortality rate was 29% (8/27 patients). Associated trauma occurred in 55% of the cases, but did mot increase the mortality rate. Prompt recognition and proper surgical treatment are essential in the management of this condition.
