We present two cases of arteriovenous fistulas associated with aneurysms of the infrarenal aorta or common iliac artery. A definitive diagnosis is sometimes difficult given the varied and unclear presentation. However, with the correct preoperative diagnosis, mortality can be reduced. Both cases, being reported here, were diagnosed preoperatively and underwent alternate surgical repairs. One case was treated by aortic exclusion, whereas the second case was treated by primary closure of the fistula. Repair techniques were chosen based on acuity of presentation. Given our experience with these two cases, we conclude that direct closure is possible but dependent on the chronicity of the lesion.
