[Ultrasound screening for abdominal aortic aneurysms - a rational measure to prevent sudden rupture].

The ruptured abdominal aortic aneurysm (AAA) has still a high hospital mortality rate of about 50 % (intervention and non-corrective treatment combined). With an easy non-invasive and inexpensive measure such as the ultrasound screening rupture threatened aneurysms can be recognized in time and then treated prophylactically, hemorrhagic shock can be avoided. Screening programs in England and Sweden currently describe an AAA prevalence of 1.5 % among screened 65-year-old males. With an absolute risk reduction for aneurysm-related death of 15.1 per 10,000 men invited for screening and a cost of £ 7,370 per quality-adjusted life year (QALY), screening for this target group is highly cost-effective. Comprehensive AAA screening requires defined criteria for the quality of the aortic ultrasound examination and for the surgical treatment of detected large AAA. These interventions should be concentrated in centers obligated to quality registry documentation. Patients with smaller AAA, requiring no repair, should be included in a surveillance program, also with registry of their long-term data.
