About this Research Topic
Endovascular aneurysm repair (EVAR) of infrarenal abdominal aortic aneurysms (AAAs) has emerged as a minimally invasive method with reduced mortality compared with open AAA repair. The price paid however is the development of various types of endoleaks, device migration, AAA rupture, development of aortoenteric fistulas, graft infection and limb obstruction. Some of these may develop intraoperatively or early in the postoperative course; however their late occurrence is the norm.
The most important measure to prevent these complications is to use the endograft only in cases where the anatomy permits this, according to the IFU of each device. Off-label use is known to increase the likelihood of getting these complications, and often patient co-morbitities dictate this potentially dangerous strategy.
The vast majority of EVAR complications may be managed with endovascular means, but very often open repair is necessary with high mortality in this often frail group of patients.
Although significant progress has been made during the last decade towards effective management of these complications, techniques are still evolving. It is therefore important to summarize these, as often there is uncertainty on which of those is the best in managing the sometimes acute problem.
The aim of this Research Topic is to provide an in-depth review of EVAR complications, including Type I, II, III, IV, and V endoleak, device migration, AAA rupture, development of aortoenteric fistulas, graft infection, and limb obstruction.
Each manuscript will ideally present current thinking on complication prevention, diagnosis/presentation, techniques of management, with description of techniques and results from the literature, unless the authors have to present their own account on these vexing problems.
This collection of articles is expected to present an up-to-date review on complications after EVAR and become a useful reference guide for vascular/endovascular specialists, fellows and residents as well.
