[Results of endovascular treatment of abdominal aortic aneurysms].

Objective: Studying the results of endovascular prosthetic repair in patients with abdominal aortic aneurysms.

Material And Methods: A retrospective study of 34 elderly and aged patients (mean age 67.4±1.24 years) with severe concomitant pathology and the risk of Euroscore averagely amounting to 13.16±0.19, subjected to endoprosthetic repair for the presence of AAA.

Results: In all 34 cases we obtained good immediate results of endoprosthetic repair of the infrarenal portion of the abdominal aorta: positioning of stent grafts was adequate, expansion complete, with no sign of endoleak. Hospital lethality rate was 0%. The intra- and postoperative periods were not accompanied by the development of neither cardiological nor neurological complications. Analysing by the McNemar criterion showed that there was a statistically significant trend towards elevation of leukocytosis and ESR after surgery (p=0.074), and for other indices the shifts were statistically insignificant or absent. Since no signs of an inflammatory process were revealed, in all cases the postoperative wounds healed with fist intension, the alterations in the blood formula were associated with resorption of thrombotic masses in the paraprosthesis space.

Conclusion: In all cases, implantation of the stent graft resulted in achieving the main objective, i. e. adequate isolation of the aneurysmatic sac in AAA. Dynamic follow up did not reveal any cases of stent graft dislocation, aneurysm rupture, thrombosis of endograft branches, or type 1a leaks.
