In 2024, Megan Ingram* of California and her husband were preparing for the birth of their third child when a 34-week ultrasound revealed a potential complication. Their obstetrics team suspected a vein of Galen malformation (VOGM) — a rare vascular condition involving significantly elevated blood flow to the head because of direct connections between arteries and veins in the developing brain. If left untreated until after delivery, VOGM commonly leads to congestive heart failure, pulmonary hypertension, and brain injury.
