Foetal medicine involves "carrying out a procedure in utero, directly on the foetus, to resolve any complications during pregnancy". Suffering from twin-to-twin transfusion syndrome, two foetuses in a life-threatening situation were saved following this type of procedure.
In October 2013, a team from the Maternal-Foetal Medicine Department at the CHU Vaudois (University Hospital Centre) in Lausanne, Switzerland, saved two foetuses at three and a half months by performing a surgical procedure in utero. The medical team "used a technique known as foetoscopy, which allows the surgeon to see the unborn babies by making a small incision in the uterus and inserting a miniature camera connected to a laser fibre". By carrying out an ultrasound scan at the same time, "foetoscopy allows diseases with a very poor prognosis to be treated". Using the laser, doctors can "remove the blood vessels causing the problem and restore even distribution".
Today, the two babies have been discharged from hospital and are doing well.
