IL TRATTAMENTO ENDOVASCOLARE DELL’ANEURISMA DELL’AORTA ADDOMINALE: NOSTRA ESPERIENZA ENDOVASCULAR TREATMENT OF ABDOMINAL AORTIC ANEURISMS: OUR EXPERIENCE

Abstract

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. Key words: Aortic aneurysm, Aortic surgery, Endovascular treatment
