Distance from origin of left common carotid artery to proximal end of stent-graft (LCCA-stent distance) was grouped according to endoleak type. Box plots show distribution of LCCA-stent distance in each group. There was no significant difference between no-endoleak group (negative) and type Ia or IIs endoleak groups (P = .22, Kruskal-Wallis test). LCCA-stent distance in type Ib, IIo, and III endoleak groups tended to be longer than that in no-endoleak group; however, this difference was not significant (P = .056, Kruskal-Wallis test). Bottom and top of each box are lower and upper quartiles, respectively. Band in the middle of each box is median. Whiskers extending from bottom and top of each box are minimum and maximum values of group, respectively.
