On Monday, July 15, surgeons announced they had successfully separated conjoined twin sisters after multiple surgeries that took 55 hours to complete, according to The Guardian.
2-year-old Safa and Marwa Ullah underwent three surgeries at Great Ormond Street Hospital in London between October 2018 and February this year.
The sisters, who hail from Charsadda in Pakistan, were born with their blood vessels and skulls joined together.
Zainab Bibi, the girl’s mother said, “We are extremely excited about the future.” Before they were born, their father died of a heart attack.
Doctors used the newest technology to complete the procedure, including 3D printing to create models to practice on, and virtual reality to create exact replicas of the girls’ skulls.
The surgeries, which were paid for by a private donor were not without complications, one of the twins suffered a stroke during one of the surgeries.
In the final operation, the doctors used their own bones to build new skulls for the girls.
On July 1, Great Ormond Street Hospital posted a photo of the twins leaving the facility on Twitter.
“We are delighted we have been able to help Safa and Marwa and their family,” neurosurgeon Noor Ul Owase Jeelani said.
According to a study by the University of Illinois at Chicago and Cook County Hospital, twins joined at the head are found in only one in every 2.5 million births and account for just 2 to 6% of all conjoined twins.
