  • Title: Aortoiliac occlusion secondary to atherosclerotic plaque rupture as the result of blunt trauma.
    Author: Beless DJ, Muller DS, Perez H.
    Journal: Ann Emerg Med; 1990 Aug; 19(8):922-4. PubMed ID: 2372177.
    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.
