Early sac shrinkage is a good surrogate marker of durable success after endovascular aneurysm repair in Japanese patients

Early sac shrinkage was associated with a low risk of late complications in Asian people and may be a good surrogate marker of durable success after EVAR. T1ELs and iT2ELs were negatively associated with early sac shrinkage and positively associated with late complications. Along with the high incidence of iT2ELs observed, T2ELs may be an important condition to consider after EVAR in the Asian population.
