    Abstract:
    Summary. In recent years, endovascular operations on infrarenal aortic aneurysm (EVAR) have not only been acknowledged as an alternative, but have become an indispensable "tool of the trade" for the vascular surgeon. As documented in many studies, perioperative morbidity is definitely much lower than in open surgery. In the long term, open surgery is also subject to complications such as rupture or aorto-enteral fistulae which necessitate secondary operations with their associated risks. There are some valid studies documenting a significantly lower mortality for EVAR than for open surgery. These datas were recently confirmed with high evidence level by the published results of UK-EVAR trial 1. The other randomized trials are currently ongoing. If the lower morbidity and lethality rate for EVAR is confirmed in these studies, the establishment of the indication for aortic aneurysm must be reconsidered with regard to the risk profile and the maximum diameter. The fact that long-term results are not yet available for the endovascular operation introduces a factor of uncertainty. Intensive follow-up observation is therefore an absolute prerequisite in patients who have undergone endovascular treatment. If the establishment of the indication is appropriate, with the new vascular prosthesis endoleaks are no longer an insoluble problem. The two methods should not be regarded as mutually competitive, but as complementary components of the treatment spectrum at every vascular center.
