Popis:	Symptomatic abdominal aortic aneurysms (AAA) account for up to 20% of patients with unruptured AAA undergoing open repair. This condition is associated with an average postoperative mortality rate after open repair of about 16%. The aim of this study was to evaluate the outcome of a consecutive series of patients who underwent endovascular repair for symptomatic, unruptured AAA.From January 2000 to October 2006, 14 patients underwent endovascular repair of intact AAA within 15 days since admission for AAA-related symptoms. In these patients, a Zenith stent-graft (Cook Incorporated, Bloomington, IN, USA) was deployed at the Oulu University Hospital, Kuopio University Hospital and Helsinki University Hospital, Finland.Stent-grafting was not successful in one patient because of access failure. The procedure was immediately converted to open repair and an aortobifemoral bypass with a Dacron prosthesis was performed. In the remaining 13 patients, bifurcated Zenith stent-grafts were deployed. After the procedure, type II endoleak was observed in three patients. The mean follow-up time was 1.9+/-1.4 years. The 2-year survival rate was 69%. The survival freedom from secondary procedure was 71% as one patient underwent stent-grafting for a distal type I endoleak 5 months after the procedure. Another patient underwent femoro-femoral cross-over bypass surgery because of right limb graft thrombosis which occurred 9 months after the procedure.These preliminary results suggest that endovascular repair of symptomatic, unruptured AAA is feasible and can be associated with a favourable outcome despite a very high operative risk.
