Doctors successfully perform brain surgery on fetus in the womb.

Doctors have performed a successful in utero surgery to repair a rare and potentially deadly prenatal condition in a fetus. In a two-hour procedure, doctors used ultrasound imaging to guide a needle through the uterus of the mother and into a vein in the back of the fetus’s head. The tiny patient was the first in a clinical trial currently underway at Boston Children’s Hospital and Brigham and Women’s Hospital, performed with oversight from the U.S. Food and Drug Administration, and was delivered by induced vaginal birth two days after the procedure.
