RESUMO
Los procedimientos de revascularización cerebral se utilizan en el manejo quirúrgico de aneurismas en los que hay gran riesgo de generar isquemia al intentar el tratamiento quirúrgico o endovascular. Además se usan en el tratamiento de tumores de base craneal que engloban e infiltran la pared de la arteria carótida interna o sus ramas principales, en la enfermedad oclusiva vascular con riesgo de producir infarto de tipo hemodinámico y en la enfermedad de moyamoya.
Cerebral revascularization procedures are used in the surgical management of cerebral aneurysms in which there is agreat risk of generating ischemia, in the attempt for surgical or endovascular treatment. Besides this, these procedures are utilized en the treatment of cranial base tumors that encase and infiltrate the trunk of the internal carotid artery orits main branches, in the vascular occlusive disease with risk of producing hemodynamic type stroke and, in the moyamoya disease. These techniques have the aim of restoring the blood supply of the brain and with it, the nutrient loading in order to avoid ischemia in territories already affected or in risk. To obtain an effective revascularization, with good clinical outcome , the patient should be chosen adequately with cerebral blood flow studies and vascular reserve, to perform a meticulous technique and the correct graft should be elected.

A 30-yr-old woman was admitted with acute headache, right hypesthesia and hemiparesis, right quadrantanoptic defect and neck stiffness. CT imaging study revealed left temporal hematoma and angio CT and cerebral digital angiography revealed and aneurysm of the left posterior cerebral artery. The patient was treated surgically. Surprisingly the clot was very firm and consistent with a mixture of tumor tissue and blood debris and in the pathological examination turned to be a glioblastoma multiforme. The aneurysm was clipped. The partner gradually improved and was treated with linear accelerator radiotherapy. This rare case is consistent with the association of malignant tumor with an aneurysm of neoplasm type.
