Ventriculoperitoneal shunt (VPS) implantation

Nana, a 3-year-old Maltese dog, had been showing multiple clinical symptoms for some time, including dizziness, difficulty moving, depression, and eventually epileptic seizures. Brain MRI results revealed significant enlargement of the 3rd and 4th ventricles and moderate enlargement of the lateral ventricles. Despite medication, Nana's clinical symptoms worsened, leading to a recommendation for surgery. Dr. László Lehner performed a ventriculoperitoneal shunt (VPS) implantation to reduce the size of the noticeably enlarged third and fourth ventricles. Since the lateral ventricles were not significantly dilated, we designed and 3D-printed a custom device to precisely insert the ventricular branch of the shunt into one of the lateral ventricles at a predetermined location, angle, and depth.

Following the surgery, Nana's symptoms completely disappeared, and she is currently in good health.
