Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
La prevalencia de aneurismas intracraneales no rotos es de un 1-3%. La tasa de rotura anual aumenta en pacientes con aneurismas múltiples que han sufrido una hemorragia de uno de ellos. Los objetivos son evaluar los resultados quirúrgicos del clipaje de aneurismas no rotos, comparando pacientes en los que se clipa un único o varios y describir las complicaciones de las intervenciones de aneurismas no rotos estableciendo los factores de riesgo de un pronóstico desfavorable. Estudio retrospectivo que incluye pacientes intervenidos de aneurismas no rotos mediante microcirugía entre 2020-2023 en nuestro centro. Se analiza la tasa de cierre, las complicaciones y el resultado funcional de los pacientes. Se identifican los factores de riesgo de mal pronóstico con un modelo univariante. Se intervinieron 82 pacientes con 114 aneurismas. En 22 pacientes se clipó más de un aneurisma durante la intervención. El 86,5% de las intervenciones se realizaron mediante abordaje miniopen. El 78,6% de los aneurismas seguidos por arteriografía 3 D presentan cierre completo. La tasa de complicaciones fue del 12,2%, incluyendo asintomáticas. La mortalidad fue del 0%. La probabilidad de empeorar el mRS 1 punto fue del 7,3% y 2 o más del 1,2%, con buen resultado funcional en el 98,9%. El clipaje de varios aneurismas en una misma intervención, empleo de minicraneotomías o la cirugía en pacientes con hemorragia subaracnoidea previa no incrementó el riesgo de complicaciones. La cirugía de aneurismas de circulación posterior aumentó el riesgo de isquemia. La indicación de cirugía de aneurismas intracraneales no rotos debe de ser consensuada multidisciplinarmente, conociendo resultados clínicos y radiológicos. La microcirugía es una técnica válida y segura, con una mortalidad 0% y una morbilidad severa del 1,2% en nuestra serie. The prevalence of unruptured intracranial aneurysms is 1-3%. The annual rupture rate increases in patients with multiple aneurysms that presented a previous hemorrhage from another aneurysm. Objectives were evaluate outcomes of clipping unruptured aneurysms, comparing patients with single or multiple aneurysms clipped, describe the complications related to surgery and to identify risk factors predicting an unfavorable outcome. Retrospective study including patients who underwent clipping of unruptured aneurysms between 2020-2023 at our center. Occlusion rate, complications, and functional outcome were analyzed. Risk factors for poor prognosis are identified using univariate model. 82 patients with 114 aneurysms were treated wit microsurgery. Multiple aneurysms were clipped in 22 patients. A mini-open approach was used in 86,5% of cases. Complete occlusion in angio3D was found in 78.6% of clipped aneurysms. Complication rate was 12.2%, including asymptomatic cases. Mortality was 0%. The probability of 1 point mRS worsening was 7.3% and 2 or more points was 1.2%, with a good functional outcome in 98.9%. Clipping multiple aneurysms, miniopen approaches, or surgery in patients with previous subarachnoid hemorrhage did not increase the risk of complications. Posterior circulation aneurysms surgery increased the risk of ischemia. The management for unruptured intracranial aneurysms should be multimodal and based on clinical and radiological outcomes. Microsurgery is a valid and safe technique, with 0% mortality and bleeding rates and 1,2% rate of severe morbidity in our serie.
