The authors herein share their experience with implantation of endografts in a total of 41 patients for an aneurysm of the infrarenal portion of the aorta. Of these, there were 34 (83%) men and 7 (17%) women, with the average age amounting to 71±7 years. All patients were found to have a history of coronary artery diseases (CAD) and arterial hypertension. The first stage in 15 (36.6%) cases consisted of stenting of coronary arteries and in 8 (19.5%) cases of coronary aortic bypass grafting. Seven patients were within 6 months diagnosed as having developed thrombosis of the stent-graft’s branch, treated by recanalization with stenting in 5 cases, and by femoro-femoral cross-over bypass in 2 cases. One patient was found to have stenosis due to bending of the left branch of the stent-graft corrected by stenting; two patients showed endoleak (in one case that of type 2 due to retrograde blood flow from lumbar arteries and in the second case that of type 3 due to impairment of the stent-graft covering integrity). Thromboembolism into the distal bed during implantation of stent-grafts was verified in 3 cases, with two of them requiring thrombectomy. One more patient was diagnosed as having dissection of the intima of the iliac artery, treated by stenting of the arterial segment involved. There were no other complications, nor lethal outcomes.

KEY WORDS: aneurysm of the abdominal portion of the aorta, endoprosthetic reconstruction.
