Abstract:
Abdominal aortic aneurysm in association with duplication of the inferior vena cava and crossed renal ectopia is described for the first time. Preoperative imaging with computer-aided tomography provided good visualization of the local anatomy, allowing the surgical approach to be adapted for the best access to the surgical site. A retroperitoneal approach was successfully used for repair of the abdominal aortic aneurysm.
