In a first for the world, a baby girl with a fatal genetic disorder received treatment for the condition while still in her mother’s womb.

After the 20-minute procedure, little Denver Coleman, who is now two months old and is from Baton Rogue, Louisiana, is ‘thriving’ and is not displaying any symptoms of disease, according to her family.

When the girl was given a dismal diagnosis while still in the womb, her mother Kenyatta Coleman, 36, recalled that it was “the most beautiful moment being able to hold her, gaze up at her, and then hear her cry.”

When Ms. Coleman received the news that the unborn child had vein of Galen malformation, she was just weeks away from giving birth to her fourth child. When the blood vessel that transports blood from the brain to the heart does not develop properly, the disorder arises, putting an extreme level of stress on the body.

Young Denver had a 50% chance of developing symptoms right away and a 40% chance of passing away before she turned ten if she was born with the condition. However, a lifeline was provided by a groundbreaking trial at Boston Children’s Hospital.

Denver Coleman  was discovered to have vein of Galen malformation, a rare ailment that causes a brain artery to discharge directly into the veins and results in dangerously high blood pressure. This condition affects one in 60,000 people.

At 30 weeks pregnant, Kenyatta Coleman (right) and her husband Derek (left) learned that their unborn child had the potentially fatal illness. When she was 34 weeks pregnant, she underwent the procedure.

Denver was born two days later in a healthy condition, therefore it was successful. Ms. Coleman calls her daughter a “fighter” and reports that she is doing well right now.

Although the procedure was done in March, a case study about it was published on Wednesday in the journal Stroke of the American Heart Association.

The woman’s lower abdomen was punctured by a needle by a ten-person medical team. They then made a precise cut through her uterine wall using ultrasonography to locate the ideal location.

Following that, doctors operated on the unborn child’s brain to implant a coil close to the artery that would restrict blood flow.

Ms. Coleman claims that for the first 30 weeks of her pregnancy, neither she nor her husband Derek, 39, experienced any difficulties.
