Carson returned to Johns Hopkins in 1984 and, by 1985, he became director of pediatric neurosurgery at the young age of 33. In 1987, Carson attracted international attention by performing a surgery to separate two 7-month-old craniopagus twins from Germany. Patrick and Benjamin Binder were born joined at the head. Their parents contacted Carson, who went to Germany to consult with the parents and the boys' doctors. Because the boys were joined at the back of the head, and because they had separate brains, he felt the operation could be performed successfully.
On September 4, 1987, Carson and a team of 70 doctors, nurses, and support staff joined forces for what would be a 22-hour surgery. Part of the challenge in radical neurosurgery is to prevent severe bleeding and trauma to the patients. In this operation, Carson had applied a technique used in cardiac surgery called hypothermic arrest.
The boys' bodies were cooled down so the blood flowed slower and bleeding was less severe. This allowed the surgeons to perform the delicate task of untangling, dividing and repairing shared blood vessels. Although the twins did have some brain damage, both survived the separation, making Carson's surgery the first of its kind.
Separating Conjoined Twins
In 1994, Carson and his team went to South Africa to separate the Makwaeba twins. The operation was unsuccessful, as both girls died from complications of the surgery. Carson was devastated, but vowed to press on, as he knew such procedures could be successful. In 1997, Carson and his team went to Zambia in South Central Africa to separate infant boys Luka and Joseph Banda. This operation was especially difficult because the boys were joined at the tops of their heads, making this the first time a surgery of this type had been performed. After a 28-hour operation, both boys survived and neither suffered brain damage.
