Reports on acute lower limb arterial occlusion caused by the traumatic compression of an abdominal aortic aneurysm without rupture are rare. The patient was a 62-year-old man who was injured when his abdomen was caught between a steel frame and the basket of an elevating truck. He was brought to our hospital with motor and sensory disturbance in the right lower limb and poor coloration. Contrast-enhanced CT showed a 40 mm abdominal aortic aneurysm with a mural thrombus protruding into the lumen and a peripheral contrast defect from the right common iliac artery. Emergency right lower extremity artery thrombectomy was performed, and the thrombus was removed below the femoral artery. However, the thrombus remained in the iliac artery area. As a result, abdominal aortic artery replacement surgery was subsequently performed. The patient required a postoperative fasciotomy, but he survived and his lower limb could be saved. He was transferred to a hospital for rehabilitation without myonephropathic metabolic syndrome. There was no other cause of thromboembolism other than the abdominal aortic aneurysm. Therefore, the mural thrombus in the abdominal aortic aneurysm was judged to have embolized into a peripheral artery due to traumatic abdominal compression.
