One in 600,000 Doctors have operated on the brain of a child with an extremely rare pathology in the womb for the first time.

A similar condition called arteriovenous malformation is considered extremely rare and occurs in 1 in 60,000 babies. This happens when arteries in the brain drain blood directly into veins instead of capillaries. As a result, the heart fills with blood, which can lead to high blood pressure.

Doctors diagnosed a woman with a malformation at 34 weeks of pregnancy, she had to perform an extremely complex surgery, the first of its kind, to save the life of the baby. In fact, surgeons operated on the baby’s brain while it was still in the womb. Fortunately, the operation was successful and within days the woman gave birth to a healthy baby.

Note that the operation was documented in a case study, and now it is hoped that doctors at Boston Children’s Hospital and Brigham and Women’s Hospital have found an effective way to prevent congenital malformations in babies. Next, the researchers plan to work with the Food and Drug Administration (FDA) to test the safety and effectiveness of this operation in order to further expand its use.

The surgeons used an MRI and revealed an extremely wide Falkyn sinus, a curved vessel in the brain that drains an artery. This meant that the probability of a malformation was 99%. To avoid this, surgeons pierced the mother’s lower abdomen with a needle and then used ultrasound to determine the correct location of the incision in the uterine wall. Next, the doctors cut open the boy’s brain and placed a coil near the artery that could restrict blood flow.

According to Boston Children’s Hospital surgeon Darren Orbach, this approach “could signal a paradigm shift in the treatment of the vessel of Galen’s anomaly.” In fact, surgeons were able to correct the baby’s deformity before it was even born. So doctors were able to prevent the development of heart failure before it happened, rather than trying to reverse it after birth.

What’s more, the researchers believe the practice could significantly reduce the risk of long-term brain damage, disability, and death in babies with this disorder.

Two days later, the women started labor and delivered a baby with limited complications due to her low weight of only 1.9 kg, which is extremely small for a newborn baby. After three weeks, however, it was clear that the baby did not need cardiovascular care, and the MRI showed no signs of abnormal blood flow to the brain.

Doctors reported that the baby and mother had already returned home, that the child felt well at six weeks, and that he “did not take any medication, ate normal food and gained the necessary weight.”
