Science Alert reports on a recent medical breakthrough in the field of surgery, where American surgeons from Boston Children's Hospital and Brigham and Women's Hospital performed a successful operation on an unborn child's brain.

The doctors were able to save the fetus by blocking a problematic vein in the brain caused by a rare congenital disease known as arteriovenous malformation, which is typically only found in one out of 60,000 newborns.

The doctors discovered the issue at 34 weeks and 2 days of pregnancy and took a risk by performing the operation on the fetus with the help of ultrasound, as they were unsure whether they could perform the surgery after the baby was born.

Although the baby was delivered early due to ruptured membranes, both the mother and baby were unharmed, and the patient is currently 6 weeks old and doing well without medication. The surgeons expressed their satisfaction with the operation's success and noted that no negative effects were observed in the child's brain.
