Riyadh, SAUDI ARABIA: In a groundbreaking medical achievement, Filipino conjoined twins Klea Ann and Maurice Ann Misa were successfully separated after a complex 13-hour surgery in Saudi Arabia on April 23, 2026. The operation, sponsored by the Saudi Arabian government, was hailed as one of the most intricate cases worldwide.
A Collaborative Effort of Experts
According to a statement from the Saudi Arabian Embassy in Manila, the surgery involved a multidisciplinary team of 30 specialists, consultants, and technical personnel. The procedure was conducted at the King Abdullah Specialized Children’s Hospital in Riyadh under the directives of King Salman bin Abdulaziz and Crown Prince Mohammed bin Salman.
The twins, who arrived in Saudi Arabia in May 2025, underwent extensive examinations to prepare for the operation. The medical team, led by Dr. Abdullah bin Abdulaziz Al Rabeeah, faced significant challenges due to the twins’ shared cerebral venous sinuses and intertwined brain tissue. Additionally, Klea Ann’s cardiac muscle insufficiency and severe kidney atrophy added to the complexity of the case.
A Five-Stage Surgical Plan
The lead surgeon, Dr. Muatasim Al-Zoubi, implemented a five-stage surgical plan to ensure the best possible outcome. The team utilized advanced imaging, anesthesia, and plastic surgery techniques to address the intricate medical needs of the twins. Despite an estimated 50% risk level, the operation was a success, marking the 70th separation procedure under the Saudi Conjoined Twins Program.
Renewed Hope for the Future
The twins’ mother expressed profound gratitude and joy following the successful surgery, which has given her daughters the opportunity to lead independent lives. This milestone not only highlights the advancements in medical science but also underscores the humanitarian efforts of the Saudi Arabian government.
This remarkable achievement serves as a testament to the power of international collaboration and medical expertise in transforming lives.
