ABSTRACT
OBJECTIVE:
To study the relative factors of type II endoleak after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms.METHODS:
Twenty-eight cases of abdominal aortic aneurysms treated by EVAR were retrospectively analyzed. The characteristics of the inferior mesentery arteries (IMA), the arc Riolan and the lumbar arteries of the cases with or without type II endoleak were analyzed.RESULTS:
Type II endoleak was found in 8 (28.6%) cases, of which, 2 were type IIa and 6 were type IIb. The diameter of the IMA originating part of the cases with type II endoleak [(4.03 ± 1.00) mm] was significantly bigger than that without endoleak [(2.89 ± 0.50) mm, P=0.007]. The number of the lumbar arteries originating from the aneurysm sac in cases with type II endoleak (3.4 ± 0.8) was significantly more than that without endoleak (1.9 ± 1.5, P=0.017). However, type II endoleak was irrelevant to the diameter of originating part of the lumbar arteries and the form of the arc Riolan. After the average 14.5 months follow-up, the aneurysm sac was found with shrinkage in 1 case, no change in 2 cases, and augment in 5 cases. Secondary transarterial embolization was performed for only 1 case.CONCLUSION:
Type II endoleak was much easily found in cases with bigger diameter of originating part of the IMA, or in cases with more lumbar arteries originating from the aneurysm sac.
