A team of Budapest’s Semmelweis University has successfully performed plastic surgery on a pair of Siamese twins conjoined at their skulls and brains, the university said. The operation was part of the second phase of a series on interventions aimed at separating the two-year-old twins. The first phase, including groundbreaking work to separate the blood flow of the brains, was conducted by a Hungarian team led by Dr. István Hudák in Bangladesh in August 2018. During the Jan. 25 operation, led by dr. Gergely Pataki, a tissue expander system of Hungarian design was implanted. The twins, Rukia and Rabia, are in good health and have already been released from the hospital, the statement said. The children have also undergone diagnostics and examinations in preparation for the operation to separate their skulls and brains. A final decision on that operation will be made in view of the results, the university said.
