A 40-hour operation at San Gerardo Hospital in Monza marked a story as extraordinary as it was painful: the separation of two conjoined twins from Senegal. The surgery made it possible to save the life of little D., while her sister T. unfortunately did not survive. The two daughters were born with an extremely rare cranio-encephalic fusion, which happens in only around one in every 2.5 million births. Bones, brain tissue, and blood vessels all combined to form a single, very complex system. Arriving in Italy in July 2024 on an Italian Air Force airplane, they were directed to Monza after an international evaluation determined that the Lombardy hospital was the best place to undertake such a delicate medical procedure. From that point on, a lengthy process of preparation, three-dimensional simulations, and multidisciplinary collaboration began. Dozens of professionals, including neurosurgeons, craniofacial surgeons, anesthesiologists, and resuscitators, collaborated for months with assistance from American experts. However, the twins' situations were significantly different: T., the more vulnerable, relied on her sibling for several vital functions. Despite the exceedingly high dangers, the team decided to attempt separation to give both of them a chance of survival. However, T.'s heart collapsed during the most critical stage of the surgery. Nevertheless, Little D. survived and has already begun a rehabilitation process that appeared to be impossible until recently. After months of immobility, she can now move, play, and grow. Her parents expressed gratitude for the doctors' dedication and assistance, saying, "Even in the midst of pain, we found strength in their closeness".
