“…VoGMs are exceptionally rare with an incidence of only 1 in 3 million. [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] Therefore, we elected to supplement our case series with additional cases from the literature to further characterize VoGMs subtypes I-IV in greater detail. This constitutes the second major limitation, namely selection bias, because authors generally tend to report their better cases only.…”

BACKGROUND Vein of Galen malformations (VoGMs) in newborns often represent life-threatening emergencies. Outcome is difficult to predict. The authors review 50 VoGM cases to correlate anatomical types with treatment and outcome. OBSERVATIONS Four distinct types of VoGMs are identified: mural simple (type I), mural complex (type II), choroidal (type III), and choroidal with deep venous drainage (type IV). Seven patients presented with mural simple VoGMs with a “single hole” fistula supplied by only one large feeder. These patients were treated electively at >6 months; development was normal. Fifteen patients presented with complex mural VoGMs. Multiple large feeders joined a single fistulous point within the wall of the varix. Patients typically presented with congestive heart failure (CHF) and required emergent transarterial intervention. Mortality was 7.7% with less than two-thirds developing normally. Twenty-five patients presented with choroidal VoGMs. Multiple large arterial feeders joined at multiple fistulous sites. Severe CHF in most patients required emergent transarterial and sometimes transvenous intervention. Mortality was 9.5%; two-thirds of the patients had a normal development. Three babies presented with choroidal VoGMs with deep intraventricular venous drainage. This phenomenon caused fatal “melting brain syndrome” in all three patients. LESSONS Recognition of the specific VoGM type determines treatment options and sets outcome expectations.

ObjectivesPosterior fossa anomalies (PFAs) are associated with a wide spectrum of neurodevelopmental disabilities, with presentation ranging from no obvious clinical symptoms to severe neurodevelopmental delay. The differential diagnosis of fetal PFAs using imaging is crucial for prenatal counseling and prognostic evaluation. Imaging of the tentorium cerebelli (TC) is critical for the differential diagnosis of fetal PFAs; however, achieving this using prenatal grayscale ultrasound is challenging. This study aimed to establish a reference range for a new measurement, the angle between the vein of Galen and the straight sinus (AVGS), measured using microvascular flow imaging, and to evaluate prospectively the effectiveness of AVGS for assessment of the position of the fetal TC.MethodsThis was a single‐center prospective validation study including singleton pregnancies examined between 16 and 38 gestational weeks at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, Beijing Maternal and Child Health Care Hospital, between January 2022 and July 2023. AVGS was measured in normal fetuses and used to establish a reference range. AVGS was then used to predict prospectively the position of the TC in 50 fetuses with one or more intracranial malformations, using cut‐offs of ≤ 5th centile or ≥ 95th centile to define abnormal AVGS. All intracranial malformations and the position of the TC in these fetuses were confirmed using fetal brain magnetic resonance imaging. The sensitivity, specificity, positive and negative predictive values and likelihood ratios were calculated to assess the performance of AVGS in the prediction of abnormal position of the fetal TC.ResultsThe study group comprised 602 singleton pregnancies, including 522 normal fetuses and 50 fetuses with an intracranial anomaly. A reference range for fetal AVGS was established. Fetal AVGS decreased with advancing gestational age. Ten of the 50 fetuses with an intracranial anomaly had an abnormally positioned TC. The sensitivity and specificity of AVGS for the prediction of abnormal position of the TC in fetuses with an intracranial malformation were 90.0% (95% CI, 71.4–100.0%) and 95.0% (95% CI, 88.2–100.0%), respectively. The positive and negative predictive values were 81.8% (95% CI, 47.8–96.8%) and 97.4% (95% CI, 84.9–99.9%), respectively, and the positive and negative likelihood ratios were 18.000 (95% CI, 4.590–70.592) and 0.105 (95% CI, 0.016–0.677), respectively.ConclusionsAVGS is a new and useful marker for the prenatal evaluation of fetal TC position. Increased AVGS (≥ 95th centile) suggests an abnormally elevated position of the TC, while decreased AVGS (≤ 5th centile) suggests an abnormally low TC. AVGS is helpful for differential diagnosis in fetuses with PFA and can inform appropriate prenatal counseling. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.
