摘要
A 78-year-old man complaining of left leg swelling was diagnosed with an abdominal aortic aneurysm with an irregular margin. A four-dimensional computed tomography (CT) showed an aortoiliac vein fistula. An AFX stent graft was urgently implanted, and a Viabahn VBX was inserted into the left iliac vein. The aneurysmal sac was embolized. After the procedure, enhanced CT confirmed a patent stent graft without any endoleak or fistula. The patient was discharged ambulatory. An aortoiliac vein fistula is a differential diagnosis for leg edema, and a four-dimensional CT is beneficial in diagnosing the condition.
