To evaluate the results and costs of surgical treatment against endovascular in non-ruptured aneurysms. Retrospective study of consecutive series non-ruptured aneurysms from a single-centre treated endovascularly (EV) and surgically (SC). A descriptive study of demographic (age, sex), characteristics of the patients and the radiological aspects of the aneurysms have been carried out. Clinical results (GOS at 6 months), angiographic data (occlusion classification) and economic costs have been evaluated in both globally, and in each of the groups. 89 patients treated between 2010 and 2015 were reviewed. Most of them were treated endovascularly (74%). There were no statistically significant differences between EV and SC groups. 89% of the patients presented favourable GOS (4–5) at six months, being this percentage similar in both groups. Complete occlusion was much higher in SC group (96%) than in EV (55%). Retreatment rate was 24% in EV group and 0% in SC group. The retreatments were more frequent in anterior circulation aneurysms and bigger aneurysms (>10mm). The expenses in the SC group come mainly from hospital stay, meanwhile in the EV group is due to embolisation materials. The average length of stay (ALOS) is higher in SC group but costs of first admission are higher in EV group (14% more). When the costs of retreatments and follow up are included the costs of endovascular treatment is much higher than the surgical (61% more expensive). results of both types of treatment are comparable. The grade of aneurysmal occlusion of the SC group was higher than the EV, as well as the stability of the treatment, requiring fewer retreatments. Although the ALOS in SC group were longer, the costs of the EV group were significantly higher than the SC group due to the costs of embolisation materials, follow up that they need and the rate of retreatment. Adequate selection of candidates for endovascular coiling could improve angiographic outcomes, reduce retraction rates, and save costs. Evaluar los resultados clínicos y angiográficos, así como los costes del tratamiento quirúrgico frente al endovascular, en el tratamiento de los aneurismas incidentales. Estudio retrospectivo de una serie consecutiva de 89 pacientes de un solo centro tratados endovascularmente (EV) y quirúrgicamente (SC). Se realiza estudio descriptivo de aspectos demográficos (edad, sexo) y de las características de los aneurismas así como se evalúan resultados clínicos (GOS a 6 meses), angiográficos
