The author analysed etiology, morphology, localization, symptomatology, diagnostics and surgical methods of treatment in 63 patients with 81 arterial aneurysms. Arterial aneurysms are not rare in vascular pathology. Most of them are atherosclerotic etiology (62%). Abdominal aorta is the most frequent localization (49%). Symptomatology and clinical findings depend on the localization, size and complications. Echosonography, with clinical finding, has presented the most accurate diagnostic procedure. Surgery is the method of the treatment of such patients, but the optimal method is the aneurysmectomy or resection of aneurysm with arterial reconstruction.
