Vein of Galen Aneurysmal Malformations in Pediatric Patients Submitted to Endovascular Treatment: Report of 3 Cases
Malformações aneurismáticas da veia de Galeno em pacientes pediátricos submetidos a tratamento endovascular: Relato de 3 casos
Abstract
Objective To report three cases of vein of Galen aneurysmal malformation (VGAM) in pediatric patients treated at the hemodynamics lab of Hospital Santa Isabel (HSI) in Blumenau, state of Santa Catarina, Brazil, from 2006 to 2020. Clinical presentation, endovascular treatment, and postprocedure evolution to date are included.
Case description Three children aged 5 to 12 months with cardiac, respiratory, or neurological damage in the neonatal stage, were referred to the neurosurgery service and diagnosed with VGAM. The three patients underwent endovascular embolization of the malformation, with different clinical evolution throughout outpatient follow-up.
Conclusion Vein of Galen aneurysmal malformations are uncommon vascular abnormalities that, until the advent of endovascular embolization, were associated with high morbidity and mortality rates. Its prognosis is linked with initial clinic, early diagnosis, and timely surgical correction.
Resumo
Objetivo Relatar três casos de malformação aneurismática da veia de Galeno (MAVG) em faixa etária pediátrica atendidos no setor de hemodinâmica do Hospital Santa Isabel (HSI) de Blumenau, SC no período de 2006 a 2020, relatando a apresentação clínica, o tratamento endovascular bem como a evolução pós-procedimento até o presente ano.
Descrição do caso Os relatos descrevem 3 crianças entre 5 e 12 meses de idade que apresentaram alterações cardíacas, respiratórias ou neurológicas no período neonatal, encaminhadas para o serviço de neurocirurgia e diagnosticadas com MAVG. Os três casos foram submetidos à embolização endovascular da malformação, diferindo na evolução clínica ao longo do seguimento ambulatorial.
Conclusão As MAVGs são anomalias vasculares incomuns de elevada taxa de morbimortalidade até o advento da embolização endovascular. O seu prognóstico está ligado à clínica inicial, ao precoce diagnóstico e à correção cirúrgica no momento adequado.
