Arteriovenous malformations of the fetal brain. Prenatal ultrasound, treatment, prognosis

A detailed literature review on arteriovenous malformation of the vein of Galen, aimed at systematizing modern knowledge on this problem, was carried out. The data analysis includes anatomical, genetic, morphological, and pathophysiological aspects, classification, clinical features, diagnosis, postnatal prognosis of mortality and neurological complications taking into account predictors of adverse outcomes. The mechanisms of decompensation caused by postnatal rearrangements of hemodynamics are described in detail.

The article also highlights the modern methods of treatment in the neonatal period.

The importance of prenatal formation of risk groups and determination of indications for the fetal surgical treatment is emphasized.
