JEDDAH: Yemeni conjoined twins “Yousuf and Yassin” will finally get the necessary medical examinations they need after King Salman ordered for their direct transfer from Yemen to Riyadh for the possibility of a separation surgery.
King Salman ordered a speedy transfer of the twins and their parents to the Kingdom, Dr. Abdullah Al-Rabeeah, the general supervisor of the King Salman Humanitarian Aid and Relief Center and a renowned pediatric surgeon, said.
The conjoined twins are expected to arrive within the next few days, state news agency SPA reported on Sunday.
According to Journal of Neurosurgery, craniopagus twins represent a rare phenomenon where twins, joined at the top or side of the head, share a portion of the skull.
King Salman has previously ordered the transfer of conjoined twins from Mauritania to travel to Saudi Arabia to separate them. Their father, who accompanied them, said the procedures for transferring the twins to Riyadh were carried out easily.
Over the years, nearly 110 cases from as many as 21 countries have been examined and assessed by the Saudi National Program for Separating Conjoined Twins. More than 50 operations have been performed so far to separate such twins.
Saudi Arabia began operating on separating conjoined twins in 1990.
Cases of conjoined twins are rare, one per 200,000 births, most of which are female, according to various studies; often, such cases occur in Central African, South East Asian and Latin American populations due to an increased rate of the incidence of identical twins; a determining factor in birthrate of conjoined twins.
