The medical and surgical team of the Saudi Conjoined Twins Program began on Thursday the separation surgery for the Filipino conjoined twins Klea and Maurice Ann, who are joined at the head, at King Abdullah Specialist Children’s Hospital in King Abdulaziz Medical City in Riyadh.
The surgery is in implementation of the directives of Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud and Prince Mohammed bin Salman bin Abdulaziz Al Saud, Saudi Crown Prince and Prime Minister.
Supervisor-General of the King Salman Humanitarian Aid and Relief Center and head of the medical and surgical team Dr. Abdullah Al Rabeeah stated in a press briefing that the conjoined Filipino twins arrived in the Kingdom on May 17, 2025.
He explained that following their admission, the medical team conducted extensive examinations and held multiple consultations, ultimately determining that the case was among the most complex in the world.
This was due to several critical medical factors, including the complex angle of the twins’ heads, extensive sharing of cerebral venous sinuses, and overlapping brain tissue.
He further noted that one of the twins, Klea, was suffering from heart failure and severe kidney atrophy leading to complete renal failure, which significantly increased the surgical risks associated with the separation procedure.
Al Rabeeah stated that the surgical team decided to carry out the operation in five stages, with the participation of 30 consultants, specialists, and nursing and technical staff across multiple disciplines, and noted that the procedure is expected to last approximately 24 hours.
He pointed out that this operation is the 70th procedure in the program, which, since its launch in 1990, has assessed and provided care for 157 conjoined twins from 28 countries across five continents.
