Tratamiento endovascular a malformación aneurismática de la Vena de Galeno / Endovascular treatment of aneurysmal malformation of the Vein of Galen

RESUMEN

Gestante de 19 años sin antecedentes de embarazos previos, presenta a las 27 semanas en ecografía del segundo trimestre hallazgo sugestivo en el feto de MAVG; a las 38 semanas se realiza parto por cesárea sin complicaciones, se planificó angiografía cerebral con embolización. Se abordó por la arteria femoral derecha utilizando lavado heparinizado continuo y sistema de navegación coaxial se estudió la MAVG de tipo mural, se canalizo de forma selectiva a las arterias coroideas postero medial y postero lateral derecha y a la arteria coroidea posteromedial izquierda y se embolizó bajo control radiológico utilizando espirales de coils y líquido embolizante Onix. Control inmediato mostro cierre completo de conexiones fistulosas y preservación de ramas sanas.

ABSTRACT

A 19-year-old pregnant woman with no history of previous pregnancies, presented at 27 weeks in a second-trimester ultrasound suggestive finding in the fetus of MAVG; At 38 weeks, cesarean delivery was performed without complications, cerebral angiography with embolization was planned. It was approached through the right femoral artery using continuous heparinized lavage and a coaxial navigation system. The mural-type AVM was studied, it was selectively channeled to the right posteromedial and posterolateral choroidal arteries and to the left posteromedial choroidal artery and it was embolized under control. radiological using coil spirals and Onix embolizing liquid. Immediate control showed complete closure of fistulous connections and preservation of healthy branches.
