Objective Target artery (TA) instability has been the most frequent indication for secondary
intervention after fenestrated and branched endovascular aortic repair (FB-EVAR) of
pararenal and thoracoabdominal aortic aneurysms (TAAAs). The aim of the present study
was to evaluate the effect of the gap distance between the endograft reinforced fenestration
and TA origin at the aortic wall (fenestration gap [FG]) on target-related outcomes after FB-
EVAR. Methods The clinical data and imaging studies of 430 patients enrolled in a …
