Doctors Pull Off Impossible Split

IV drip in focus with surgeons operating in the background — MEDICAL MIRACLE

Two-year-old twin girls conjoined at the head were safely separated in a 25-hour operation in St. Louis, and that single fact says everything about skill, planning, and grit.

Story Snapshot

SSM Health Cardinal Glennon Children’s Hospital confirmed a successful separation in February 2026.
The procedure spanned about 25 hours from start to finish, with teams rotating in shifts.
The twins, Hiyab and Wuhbto, are Ethiopian and now recover in separate beds with rehab support.
Doctors staged multiple surgeries before the finale to reduce risk and map shared vessels.

A rare, high-stakes operation that demanded months of planning

SSM Health Cardinal Glennon Children’s Hospital announced the successful separation of two-year-old twins, Hiyab and Wuhbto, on February 24–25, 2026.

The team performed the final separation after extensive preparation and earlier staged procedures, which the hospital described as six major neurologic and reconstructive surgeries that set the table for the finish.

Hospital leaders credited careful imaging, 3D planning, and multi-specialty coordination for the result. They called the case among the most complex and rare procedures in United States pediatric care.

CBS News reported the separation took about 25 hours, aligning with the hospital’s timeline for the February operation. The hospital placed the girls into separate beds after separation and began a carefully scripted recovery plan.

Staff moved swiftly from the operating room to intensive care and then to rehabilitation planning. Ranken Jordan Pediatric Bridge Hospital supported early rehab milestones, giving the girls a bridge from acute care to daily progress. The path reflects a playbook seen in other rare cases: stage, separate, then rebuild skills.

What “successful” means in this kind of pediatric surgery

In craniopagus cases, “success” starts with both children surviving the separation and stabilizing in the first month. A recent thirty-year scan of the medical literature underscored how anatomy and staged plans change outcomes, with multi-step approaches and non-emergency timing linked to higher survival.

The New England Journal of Medicine has highlighted that mortality in these separations can approach one in four, which is why teams load the odds by staging, mapping veins, and rehearsing flow down to minute-by-minute handoffs. This case followed that logic carefully.

The hospital’s account emphasizes the power of a large team working in rhythm. Neurosurgeons, plastic and reconstructive surgeons, pediatric anesthesiologists, critical care nurses, and rehab specialists all had roles.

Leaders described the work as “sublime precision” and “complex coordination,” which tracks with best practices seen across published cases worldwide. When a single misplaced cut can cause catastrophic bleeding, planning is not bonus points. It is survival gear, and it shows here.

From shared vessels to separate lives: why staged steps matter

The team used earlier surgeries to expand scalp tissue, manage shared blood flow, and prepare safe access routes, according to contemporaneous reports.

That sequence reduces the shock of sudden separation and gives surgeons options when anatomy surprises them.

Research on two decades of craniopagus separations shows staged operations improve outcomes, especially in total or vertical fusions where veins run complex and deep. The principle is simple: buy time, grow tissue, and turn a cliff jump into a staircase.

After the final separation, early rehab began. Reports say the girls reached new milestones with structured therapy, echoing published cases where one twin may race ahead while the other needs more time and tools. Families and clinicians should expect plateaus and bursts.

This is not a victory lap after a long night. It is the first mile of a long road. Yet starting that road as two children, in two beds, is the win everyone worked to earn.
