Resumo

Introdução: A malformação arteriovenosa cerebral (MAV) evolui de forma assintomática e pode causar lesões graves, na maioria das vezes irreversíveis, com diagnóstico difícil, tratamento controverso e acesso restrito a centros terapêuticos de referência. Relato de caso: relato de um caso de acidente vascular cerebral hemorrágico intraparenquimatoso com presença de MAV perimesencefálica esquerda, em paciente do sexo masculino de 66 anos. Em relação à abordagem terapêutica, descreve-se aqui o procedimento de correção da MAV por meio de micro-ressecção neurocirúrgica. Conclusão: Pensando nisso, o presente estudo teve como objetivo discorrer a história clínica, bem como descrever a correção da MAV silenciosa após acidente hemorrágico intraparenquimatoso.

Abstract

Background: Cerebral arteriovenous malformation (AVM) evolves asymptomatically and can cause serious injuries, most of the time irreversible, with difficult diagnosis, controversial treatment and restricted access to reference therapeutic centers. Case Presentation: a case of intraparenchymal hemorrhagic stroke with presence of a left perimesencephalic AVM in a 66-year-old male patient is reported. Regarding the therapeutic approach, the AVM correction procedure through micro neurosurgical resection is described here. Conclusion: With this in mind, the present study aimed to meet this expectation, as well as to describe the correction of silent AVM after intraparenchymal hemorrhagic accident.
