At 31 weeks and 5 days pregnant with identical twins, Amberlyn Smith went to her bi-weekly ultrasound feeling confident. Just two weeks prior, both of the twins had grown appropriately and screening tests came back normal. But that day, Dec. 23, there was a clear discrepancy in their size, as well as a notable abnormality in their blood flow. Smith was immediately sent to see an intervention specialist with UTHealth at Children’s Memorial Hermann Hospital, where she emergently delivered the twins the next morning, on Christmas Eve.
