Abstract

About 40% of patients with AAA, due to the anatomical characteristics of the aorta, cannot be candidates for EVAR. Anatomical features that are difficult or unacceptable for stent-graft placement include short or no proximal neck, angular, tapered neck, and vessel diameter that exceeds the existing capabilities of endoprostheses. In patients where traditional surgical correction is not an acceptable option, various technological methods and equipment are used. The observation included 18 consecutive patients with AAA, where EVAR was performed. When analyzing the anatomical characteristics of the aneurysmal sac, 9 (50%) patients were classified as patients with an unfavorable proximal neck of the aneurysm, the so-called “hostile neck”. 4 EVAR interventions were complex (2 patients with parallel grafts), which made it possible to achieve an increase in the proximal infrarenal zone implantation up to 16-20 mm, and supplemented or additional endovascular procedures - in our case, implantation of “Aptus Heli-FX” endoancors in 5 patients. The comparison group consisted of 9 patients with a standard aneurysm neck, where standard EVAR procedures were performed. The main anatomical difference in the groups was the length of the aneurysm neck - 9.8 mm and 36.1 mm in groups I and II, respectively (p - 0,0003). EVAR in the groups were carried out without significant complications and operation death; in the first group, the duration of the operation (p-0,01), the amount of contrast (p-0,03) and the fluoro time (p - 0,01) were significantly increased than in the patients of group II. The postoperative period did not differ between the groups. So the use of modern technological methods allows to significantly expand the indications for EVAR in patients with unfavorable anatomy.
