Ruptured Abdominal Aortic Aneurysm Concomitant with Lower Extremity Ischemia, following Abdominal Blunt Trauma

Abstract

The case patient was a 61-year-old man who fell while working on the back of a truck and bruised his abdomen. Immediately thereafter, the patient started experiencing lumbar pain and weakness in both lower limbs. He was then transported to our hospital by ambulance. Based on the abdominal CT findings, he was diagnosed with acute lower limb ischemia due to a ruptured abdominal aortic aneurysm. The patient underwent graft replacement surgery within 3.5 hours after the onset of the rupture. The patient had no adverse findings, such as ischemia-reperfusion injury and compartment syndrome, after resumption of blood flow (6.5 hours after the onset) and both lower limbs were well perfused. Although there was mild muscle weakness and numbness in the distal left lower limb, the patient was discharged 9 days after surgery.
