Fig. 1From: Embolization for type 2 endoleak with sac expansion after endovascular repair of abdominal aortic aneurysm: safety and effectivenessImages of an 88-year-old man with T2EL (case no 1, Table 1). a Enhanced CT showed that the aneurysm expanded with persistence of T2EL (arrow) 15 months after EVAR. b Endoleak angiogram performed via a microcatheter demonstrated that the endoleak involved four vessels (arrows). Arrowhead indicates the micro catheter tip that was advanced into the endoleak sac through the left fourth lumbar artery. c Roentgenogram showed NBCA injected to fill simultaneously the aneurysmal sac (arrowheads) and the involved lumbar arteries (arrows). d Plain CT showed radiopaque NBCA accumulations in the endoleak sac (arrow) and lumbar arteries (arrowheads). e Enhanced CT obtained 6 months after the embolization showed another small endoleak (arrow) with no further expansion of the aneurysmBack to article page
