Howard DPJ, et al. - Using prospectively collected individual patient data from The Global Registry for Endovascular Aortic Treatment (GREAT), researchers assessed if large proximal aortic neck (LAN) diameter is associated with adverse outcome. They studied a total of 3,166 consecutive patients, from 78 global centres, receiving Gore Excluder stent grafts for infrarenal abdominal aortic aneurysm repair between 2011 and 2017 and identified a correlation of LAN with delayed Type IA endoleak occurrence and lower overall survival.
