Management of Giant Posttraumatic Abdominal Aortic Pseudoaneurysm and Aortic Occlusion Using a Unique Hybrid Procedure Combining Transcatheter Device Closure and Open Surgical Repair

Posttraumatic abdominal aortic pseudoaneurysm (AAP) is a rare but life-threating disease. Here, we described a case of posttraumatic AAP with acute abdominal aortic occlusion and its successful treatment using a unique hybrid procedure. An 18-year-old male was referred, with a giant AAP among visceral arteries, which occluded the aorta and left renal artery. An infrequently used ventricular septal device was delivered via femoral access and successfully plugged the tear. Then the isolated pseudoaneurysm was resected through open surgery without major bleeding. At 6 months after operation, the patient was alive without evidence of complications. This hybrid procedure combining transcatheter device closure and open surgery was a successful attempt in the subemergency treatment of posttraumatic AAP.
