The highly complex surgery involved multiple operations on Safa and Marwa Ullah, who were born in Pakistan in January 2017 with a condition known as “craniopagus” in which the girls’ skulls and parts of their brains were joined and intertwined. Having twins joined at the head with fused skulls and separate bodies occurs in less than one in a million births, while having the connection extend into the brain tissue is rarer still. Around 50 sets of craniopagus twins are estimated to be born around the world every year, of which only around 15 are thought to survive beyond the first 30 days of life.
The procedures took place at London’s Great Ormond Street hospital, with the girls well enough to be discharged from hospital four months later on 1 July.
