Comparison of outcomes for double fenestrated endovascular aneurysm repair versus triple or quadruple fenestrated endovascular aneurysm repair in the treatment of complex abdominal aortic aneurysms

Co-FEVAR is not associated with an increase in perioperative mortality and morbidity compared with St-FEVAR. Co-FEVAR requires longer procedure and fluoroscopy duration, but technical success rates are as high as in St-FEVAR. A liberal use of Co-FEVAR is therefore justified whenever a longer and higher proximal sealing zone is needed.
