Study finds in utero surgeries for spina bifida preferable to operating after birth.
Doctors at Vanderbilt University started experimenting with correcting spina bifida on a fetus in the womb more than a decade ago.
The surgery gives doctors and their tiny patients a chance to meet before they are born.
Spina bifida is a birth defect in which the spine doesn't fully close around the spinal cord, leaving it exposed.
Surgery to repair the spine normally occurs shortly after birth, but a new, multi-hospital study looked at operating during the second trimester of pregnancy.
"The trial really showed clearly that when we compared the patients who had had surgery post-natally versus prenatally, on average, the kids that were repaired in utero had better outcomes," says pediatric neurosurgeon Dr. Nalin Gupta.
Children operated on before birth were nearly a third less likely to need a shunt to remove fluid from the brain.
They were also more likely to walk unassisted.
Experts are quick to note this is not a cure, and there are significant risks.
Babies who underwent prenatal surgery were more likely to be born premature and have respiratory problems.
Despite these challenges, doctors are keeping a positive outlook.
"This has been a relatively neglected disease, people felt that there was nothing that could be done for these children," says Dr. Diana Farmer.
Now there's new hope shared by everyone involved.
