Chiang Mai University Hospital Successfully Delivers Rare Set of Identical Quadruplets

On October 14, 2026, the Faculty of Medicine at Chiang Mai University announced a significant medical milestone: the successful delivery and survival of identical quadruplets conceived naturally. According to Khaosod Online, the case is exceptionally rare, occurring in approximately one in 700,000 pregnancies.

Associate Professor Dr. Naren Chotirosniramit, Dean of the Faculty of Medicine, reported that the delivery required a specialized multidisciplinary team of 30 medical professionals. The infants, who shared a single placenta, were delivered via surgery. The hospital confirmed that eight months have passed since the birth, and all four children remain healthy and safe.

For residents and visitors in Thailand, this achievement highlights the advanced capabilities of the country’s university-affiliated medical centers in handling high-risk, complex obstetric cases. While the immediate medical crisis has been resolved, the long-term developmental monitoring of the children will continue under the care of the university’s pediatric specialists. This case serves as a testament to the efficacy of multidisciplinary medical coordination in Thailand’s public health sector. Further details regarding the specific ongoing care protocols for the children have not been disclosed.
