RESUMO

Os autores apresentam série 50 pacientes submetidos a cirurgia estereotáctica para processos expansivos intracranianos. Em 12 casos realizou-se um procedimento terapêutico: ressecção tumoral guiada em 5 pacientes e aspiração do conteúdo da lesão nos outros 7. Neste estudo confirmam-se a grande precisão e a baixa morbidade relacionadas com as técnicas estereotácticas. A tomografia computadorizada e a ressonância magnética determinam com acurácia as coordenadas estereotácticas, mas em certos casos a estereo-angiografia cerebral deve ser realizada. As ressecções tumorais guiadas por estereotaxia permitem o tratamento de lesões cerebrais profundas ou em áreas funcionais anteriormente consideradas como inoperáveis. A literatura pertinente é discutida.

Palavras-chave: estereotaxia, tumores encefálicos, biópsia, microcirurgia.


ABSTRACT

The authors present a study about 50 stereotactic procedures for intracranial lesions. In 12 cases stereotaxis was used as a treatment: stereotactic surgical resection (5 patients) and aspiration of lesions (7 patients). This study confirms the great accuracy and low morbidity of the stereotactic techniques. Computed tomography and magnetic resonance imaging determinate the precise stereotactic coordinates, but in some cases it is necessary to perform stereo-angiography. The stereotactic surgical resection of brain tumors allows the treatment of deep lesions or located at functional areas and considered to be inoperable before. The related literature is discussed.

Key-words: stereotaxis, brain tumors, biopsy, microsurgery.
