Background. This report prospectively analyzes collected data of endovascular treatment
of abdominal aortic aneurysms in 114 patients selected to receive stent implantation based on
anatomic criteria and surgical risk. Methods. From December 2002 to May 2006, 114 patients with
abdominal aortic aneurism receive endovascular treatment. 108 were men (94,7%) and 6 female; age
range was 57-86 years with mean age of 73.3. The mean maximum diameter of the AAA was 5.71
cm (range 3.7- 13.0). Three different types of stents were used most of which were bifurcated in design
(97,3%). Endograft used were: Excluder, Talent; Zenith-Cook. Results. No perioperative mortality
was observed; 5 (4,3%) type I and 11 (9,6%) type II endoleak were detected; Iliac extension with
exclusion of the internal iliac artery was required in 27 cases. We observed 2 right branch, 2 iliac lesions,
2 ematoma and 1 distal vessels embolization surgically treated Mean follow-up period was
18,6 months. 17 patients died during follow-up. 11 endoleak were discovered during follow-up and in
3 cases thrombosis of a branch occurred. Mean aneurysm diameter, neck diameter, iliac or hypogastric
diameter or the clinical characteristics showed no statistical significant differences among the
three group (on the results). In each group influence of aneurysm and neck morphology and diameter
on type I or II endoleak was analyzed but no statistical significant differences were detected
among the three groups except for type-II endoleak in the Talent group that was registered in 100%
of no mural thrombus – aneurysms (p<0,05). Conclusions. Together with aneurysm sac growth andbranch vessels’ patency, structural failures continues to be a challenging problem. As long as no solution
will be find out for them endovascular aneurysm repair will remain an imperfect long-term
treatment and continued follow-up will be mandatory.
