a
Excluded from study; FD prolapsed into aneurysm at 3 months.
b
Excluded from study; aneurysms too well occluded at 3 months to be re-treated.
FRED: flow-redirection endoluminal device; LVIS: low-profile visualised intraluminal support; LEA: liquid embolic agent; IQR: interquartile range; /: not applicable.
