Angiomas cavernosos de tronco cerebral / Brain stem cavernous angiomas

ABSTRACT

Introduction: The incidence of intracranial aneurysm ranges from 0,5 to 0,6 por ciento and the diagnosis of incidental aneurysms has increased due to the development of non invasive neuroimaging techniques. Minimally invasive treatment modality in incidental cases. Methods: A series of 119 incidental aneurysms in 77 patients were treated by embolization with GDC coils. Results: One hundred and seven aneurysms were succesfully embolized with total or almost total occlusion rate of 86,8 por ciento. Thirteen procedural complications occurred causing definite morbidity in 5 patients and one death. None of the embolized aneurysms bled during the follow up. Conclusion: Embolization of incidental aneurysms is associated to a low morbidity and mortality rates (AU)
