Preliminary study of endovascular aneurysm repair using fenestration on table for abdominal aortic aneurysm with short proximal neck

Objective: To investigate the clinical value of endovascular aneurysm repair(EVAR) using fenestration on table for abdominal aortic aneurysm(AAA) with short proximal neck. Methods: A retrospective analysis of four cases with short proximal neck AAA from Aug. 2015 to May. 2016 of Tianjin Medical University General Hospital treated by EVAR using fenestration on table. Fenestrated stent-grafts were designed according to the preoperative computer tomography angiography(CTA) data. All cases underwent EVAR with the fenestrated stent-grafts on table to revascularize visceral branches. Results: FEVAR was performed in all of the 4 cases successfully. Device deploying success rate was 100%. No type Ⅰ endoleak was found in all of the 4 cases. Transient renal dysfunction occurred in two cases during 7 post-operative days and improved with the medical treatment. Mean follow-up period was 4.7 months(range, 1-9 months). CTA (3 cases) and ultrasonic imaging(1 case) were performed postoperatively. No endoleak was found around fenestrated stent graft and patency of visceral stent grafts were maintained in all of the 4 cases. Conclusion: EVAR using fenestration on table for short proximal neck AAA is safe and feasible, which expand the indication of EVAR for AAA, and the long-term safety and outcomes of this technique need to be assessed in the future.
