Surgeons at the National Hospital of Paediatrics (NHP) have successfully separated five-day-old conjoined twins.

NPH Director Prof. Dr. Nguyen Thanh Liem said that they had to conduct the separation operation two days ahead of schedule due to one of the girls’ weakness.

The girls are now in better condition than before the surgery, said Dr Liem, but both are put under special care as they have a congenital heart malformation.

The twins are expected to receive heart treatment two weeks following the separation, he added.

The thoracopagus twins, Nguyen Thi Ngoc Mai and Nguyen Thi Minh Hong, weighing a total 4.7kg were born on Sept. 16 in northern Bac Ninh province conjoined at the chest. Both shared a single sternum and pericardium (heart sac).

The twins were taken to the NHP three hours after birth. They were suffering from severe respiratory failure and was being assisted by breathing machines./.
