Abstract：Objective To investigate the application of computed tomography angiography (CTA) in the identification of endoleaks
after endovascular aortic aneurysm repair. Methods We retrospectively analyzed the clinical data of patients with aortic aneurysm
who underwent endovascular repair (EVAR) and CTA reexamination in the follow-up duration. The occurrence of endoleak after
stent implantation as well as the change of aneurysm, and its complication relative to the stent-graft segments were observed. Results
Fifty two patients with mean age of (68.92±22.73) years old who underwent aortic aneurysm treated with EVAR were included.
Of these patients, 15 cases (28.85%) were observed with 16 sites of endoleak on or nearby the stent-grafts. Among them, 1 case
(1.9%) showed typeⅠb, 7 cases (13.46%) showed typeⅡ and 7 cases (13.46%) with 8 sites showed type Ⅲ. For the 15 patients with
endoleaks, 8 cases were found bigger aneurysm than that before EVAR, so they were followed-up closely; 1 case showed aneurysm
rupture on stent-graft segment and given-up of treatment; 1 case died with rupture of abdominal aneurysm after 2 months follow
the chest EVAR; 3 cases complicated infection of aneurysm on the segment of stent-graft and one of them had to be amputated after
removal of the stent-graft. Conclusion After EVAR surgery, patients with aortic aneurysm should be followed up by CTA, to identify
the types of endoleaks of stent-grafts. Attention should be payed to the typeⅡand Ⅲ, as well as the infection and rupture of stentgrafts,
which can result in serious consequences.
