Aortoiliac occlusion secondary to atherosclerotic plaque rupture as the result of blunt trauma.

Abstract

Abdominal aortic injuries secondary to blunt trauma are uncommon, particularly without associated visceral injury or external signs of localized trauma. Blunt trauma-induced abdominal aortic injuries most frequently result in intimal tearing. The most common mechanism is localized impact over the lower abdomen from sudden deceleration against a fixed object. We present the case of a patient with atheromatous plaque rupture in the distal abdominal aorta associated with acute aortoiliac occlusion as the result of a fall. Atherosclerotic disease may be present in young asymptomatic individuals and may be a predisposing factor for aortic intimal tearing. A high degree of suspicion and periodic reassessment of peripheral circulation in trauma patients are required to ensure early diagnosis of this injury.
