Seat Belt Injuries of the Abdominal Aorta in Adults—Case Report and Literature Review

Blunt abdominal trauma with major vascular involvement is found to be rare. Although few series have been reported in the literature, the true incidence of blunt abdominal aortic injury is unknown. Different modalities of blunt trauma may occur among civilians with steering wheel and seat belt injury secondary to motor vehicle accident the most frequent. Mechanical forces produce variable patterns of injury; therefore, the onset of signs and symptoms can be different. Dissection and thrombosis of the abdominal aorta have been frequently described among seat-belted adult patients with major vascular involvement. The associated abdominal viscus and/or vertebral lesions must always be taken into account. Prompt diagnosis allows adequate surgical treatment. We present the case of a 66-year-old woman, restrained front passenger involved in a motor vehicle collision, who had small bowel transection, vertebral fractures, and aortic partial occlusion below inferior mesenteric artery with bilateral iliac artery involvement. Along with the case reported, the purpose of this study is to highlight and compare features and management of the previous cases described in the English literature.
