A Phase II Trial of Fetal Embolization for Vein of Galen Malformation

Conditions

• Vein of Galen Malformations

Eligibility Criteria

Sex

FEMALE

Age

18 Years - N/A

Healthy Volunteers

Not accepted

Interventions

• Fetal embolization of vein of Galen malformation using Target XL and XXL Detachable Coils — DEVICE
  The study involves a single fetal intervention of maternal transuterine, fetal transcranial torcular puncture and median prosencephalic vein embolization. Detachable platinum coils (Target XL and XXL Detachable Coil, Stryker Neurovascular) will be used to pack the prosencephalic varix.

Study Details

This is a prospective, single-arm non-randomized interventional study of fetuses to assess the efficacy and safety of fetal embolization of VOGM. Subjects will receive a one-time study intervention of fetal embolization, at or after 34 weeks of gestation. After delivery, neurological assessments will be performed every 6 months for 2 years (adjusted for gestational age). Data will be compared to historical cohorts.
