Since 1986 in the radiodiagnostic department of the District Institute of National Health in Lucenec 17 768 abdominal sonographies were made. In the total number of examinations by means of ultrasonography 22 aneurysms of the abdominal aorta were diagnosed, incl. one ruptured one. The high mortality rate on operation of ruptured aneurysms can be reduced in particular by elective resections of non-ruptured aneurysms. Examination of the abdominal aorta should be made as a matter of routine, independently on indication of abdominal sonographic examination, in particular in elderly patients.
