UNASSIGNED: @entity439 located on the posterior @entity5487 are rare, and treatment guidelines for them have not yet been established. In this paper, we present the results of a retrospective study which analyzes the management and treatment of 15 @entity1 with posterior @entity5487 from 2004 to 2013. The @entity439 were @entity397 and presented with a @entity510 . Of the 15 @entity439 , ten were of saccular, three fusiform, and two were dissecting. Computed tomography angiography or digital subtraction angiography revealed other @entity439 or @entity1779 in seven @entity1 . Either surgical or endovascular treatment was performed depending on the localization and morphology of the @entity439 . Six @entity439 were coiled, and surgery was performed in nine cases. Of the nine surgically treated @entity1 , six (75  %) had good outcomes. Of the six @entity1 treated using endovascular procedures, three @entity1 (50  %) recovered. @entity1 outcomes were classified using the Hunt_Hess scale. @entity1 with Hunt_Hess 1-3 recovered without a @entity51 . On the other hand, @entity1 with Hunt_Hess 4-5 had a risk of up to 93  % of @entity204 or a poor outcome. In two cases of endovascular and in two cases before any therapy, aneurysmal rebleeding occurred and resulted in deterioration of clinical state of the @entity1 and a poor prognosis with high risk of @entity204 . This study shows the necessity of acute treatment of @entity5487 , of thorough diagnostic, and of interdisciplinary cooperation.
