Abdominal aortic aneurysms are a common condition whose prognosis without treatment is poor because of the lethality in case of breakage. An early diagnosis is thus necessary by screening or symptoms recognition. Surgery is not the only option then, continuous monitoring and medical treatment being sometimes possible. If curative treatment is undertaken, endovascular technique is an alternative to open surgical repair but its indications are not yet fully established and endovascular grafts have not the same longevity as open surgery. A review of the indications for endovascular repair in patients operated at the Geneva University Hospital has been used to illustrate the importance of individualized care for each patient.
