DOI: 10.1016/j.avsg.2019.04.051
Abstract: INTRODUCTION Fenestrated/branched endovascular aneurysm repair (F/B-EVAR) achieves more extensive proximal seal than conventional infrarenal devices, thereby increasing aneurysm exclusion durability. Optimal seal zone length remains undefined. We assessed relative risks and benefits of extending proximal… read more here.
