Background. The department of neurosurgery at the University Hospital of North Norway has treated intracranial aneurysms since 1986. This study was conducted in order to evaluate outcomes after the introduction of endovascular therapy in 2000. Material and methods. We included all patients treated for intracranial aneurysms during the years 1999 through 2002 in a retrospective, cross-sectional study. Data were collected from patient files. Results. We treated 113 aneurysms in 104 patients in 108 procedures. 81 (78%) patients were treated after a subarachnoid haemorrhage, while 23 (22%) underwent treatment of an unruptured aneurysm. 75 (66%) aneurysms were operated with craniotomy and clipping of the aneurysm neck, 38 (34%) were treated with coiling. The choice of modality was dependent on the location and shape of the lesion. Complications related to the treatment were more common after surgical treatment than after coiling (41 versus 16%, p=0.009), but the method of treatment did not influence long-term outcome evaluated according to the Glasgow Outcome Scale (GOS). All patients who underwent treatment for an unruptured aneurysm achieved a good outcome (GOS score 4 or 5), while patients treated after subarachnoid haemorrhage experienced significantly (p = 0.003) less favourable outcomes. Regression analysis revealed poor clinical condition (high Hunt & Hess grades) after the haemorrhage as the only independent predictor of outcome. Interpretation. The university hospital has treated an increasing proportion of patients with intracranial aneurysms with endovascular coiling after introduction of this method in 2000. The outcomes presented in this study equal those published from international multicentre trials.
