Surgeons repair spina bifida in fetus for 1st time in Canada, hospitals say

For the first time in Canada, a team of surgeons has successfully performed in-uterosurgery to repair a form of spinabifida, two Toronto hospitals say.

On Tuesdaymorning, Mount Sinai Hospital and the Hospital for Sick Children (SickKids) introduced Eiko Crisostomo, now almost three months old, and her parentsat a news conference in Toronto.

Eiko'sparents, Romeo Crisostomo and RomeilaSon, learned their baby had spinabifidaat their 20-week ultrasound.

"Usually that's that time when you find out the gender," Son told reporters. "We were very excited to finally have a girl after having four boys."

But they were "devastated" to find out that their daughter would be born with a form of spinabifida calledmyelomeningocele, and would likely suffer brain damage and be in a wheelchair,she said. Son was especially worried her daughter would be in pain and exposed to repeated surgeries during her life.

Myelomeningoceleaffects about 120 to 150 babies in Canada every year, and occurs when the spinal column fails to close duringfetal development.

The spinal cord comes out and is exposed to amniotic fluid, which becomes acidic, said Dr. Greg Ryan, head of MountSinai Hospital's neurosurgery team and one of two doctorswho led Eiko'ssurgery.

The resulting damage to the spinal cord nervous system causes various degrees of paralysis. Many children need a permanent shuntto relieve pressure on their brains. According to Mount Sinai Hospital, fewer than half of children with spinabifidalive independently when they become adults.

Son was determined to do whatever she could to help her babyand upon learning the in-uteroprocedure is performed in the U.S., was prepared to go.

But she met with doctors at Mount Sinai Hospital who had done in-uterosurgeries before for other conditions, and they said they were prepared to offer it to her there.

"I wasn't scared," Son said on Tuesday. "I had zero doubt and 100 per cent confidence."

On June 4, ajoint team of doctors and nurses from Mount Sinai and SickKidsperformed the surgery,when Eiko was at 25 weeks gestation. Her mother was given a general anesthetic, and the team inserted a needle through her abdomen to temporarily anesthetize and paralyze the fetus.

They then made incisions into the uterus to reach the fetus and close the skin over the spinal defect. The team also replaced amniotic fluid lost from the uterus during the procedure through a catheter a critical step to keeping the fetus healthy.

More than two months later, on Aug. 19., Eikowas born by caesarean section.

Now almost three months old, Eiko'sparents arehopeful about her future, as shesmiled and wriggled in her father's arms while her mother spoke on Tuesday. At home, Eikois "doing very normal baby things," Son said.

"Right now, her brain is stable, her legs are moving and kicking as you can see," Son said. "All of our prayers were answered. She's our little miracle."

The in-utero surgery does not guarantee Eiko will not be affected by spinabifida, but research done in the U.S. shows it improves her chances.

According to a U.S. study published in 2011, provided by Mount Sinai Hospital, brain malformations were reduced by one-third; children were half as likely to need walking aids or wheelchairs, and the need for brain shunts was reduced by half.

Since Eiko'ssurgery in June, the hospitals said Tuesdaythey had done the procedure three more times.

Son said she is happy that the in-uteroprocedure is now available to parents "on Canadian soil."
