Incidence rate of arterial aneurysms is 3.4-4.6% of that of vascular diseases and has a tendency towards further increase. In National Research Center of Surgery, RAMS, 410 patients with arterial aneurysms of various localization were treated. The majority of the patients were men--221 (65.4%). Surgical procedures were performed in 338 (82.4%) patients. Reconstruction surgeries were performed in 273 (80.8%) patients, ligature surgeries--in 65 (19.2%) patients. In early postoperative period good results (recovery and improvement) were seen more often (p 10 years) were also better after reconstruction than after ligature surgeries.
