Regarding 'primary aortoenteric fistula following endovascular aortic repair due to type II endoleak'

摘要

We read with interest the article by McPhee et al. The authors argue that the case is best characterized as a primary aortoenteric fistula (AEF) as a native aortic wall eroded into the duodenum from ongoing aneurysmal enlargement. We have recently published a very similar case in a patient without endoleaks but with evident sac expansion that was attributable to endotension. Clinical presentation and surgical findings were very similar to those reported by McPhee et al. We think that both cases are secondary and not primary fistulas because primary AEF is a spontaneous communication between an unoperated abdominal aneurysm and the duodenum.
