BACKGROUND: There is an ongoing debate on the preferred treatment of @entity438 . The purpose of this study was to assess the clinical and imaging outcomes comparing conventional coiling and clipping of unruptured and @entity438 . METHODS: We searched the electronic databases PubMed, EMBASE, and Cochrane from January 1990 to May 2014. RESULTS: 51 studies were included in the analysis. Favorable outcome was reported in 97.0% and 77.1%, and in 97.2% and 72.8% of @entity1 after coiling and clipping of unruptured and @entity1756 , respectively. Death rates were 1.1% and 8.4% after coiling and 0.3% and 14.7% after clipping of unruptured and @entity1756 , respectively. Initial adequate occlusion was obtained in 89.6% and 92.1% after coiling of unruptured and @entity1756 , respectively. Only three studies on clipping reported on @entity439 during follow-up. CONCLUSIONS: Both coiling and clipping are procedures with low mortality and morbidity rates and, although it may seem that coiling is better for @entity1756 and clipping for unruptured @entity439 , no firm conclusions can be drawn due to the variation in study design and lack of standardized reporting on MCA @entity439 treatments. Standardized observational studies from prospectively kept databases are needed to allow stronger conclusions to be drawn on what is the best treatment for @entity438 . Comparable with @entity439 in other locations, a multidisciplinary approach is therefore recommended with selection of treatment modality based on the clinical condition of the @entity1 and the morphological aspects of the @entity439 .
