Background. Endovascular stent-graft repair of abdominal aortic aneurysms was introduced in 1991. Long-term results from randomised studies are still not available. Aneurysm ruptures after stent-graft repair have been reported, and there has been a considerable need for redo procedures. Material and results. At Rikshospitalet in Oslo, Norway, 26 stent-graft implantations for abdominal aortic aneurysms were performed during the years 1996-2000, two of which were primary technical failures immediately converted to open repair. During follow-up, two patients have died from unrelated causes after six and 12 months. Eight patients were converted to open repair 8-50 months (median 31) after implantation. Indications for conversion were migration (n = 4), increasing aneurysms diameter (n = 3) and rupture (n = 1). Of the 14 patients still under observation, six have had one or more endovascular interventions (a total of 10) for failing graft. Interpretation. Continuous technology development has been used as an argument to postpone randomised studies, as improved results are expected with new generations of stent-grafts. There is a need for discussion of the strategy for the further use of endovascular repair of abdominal aortic aneurysm.
