The article presents a clinical case of the simultaneous execution of endoscopic ventriculocisternostomy of the third ventricle floor (ETV), aqueductoplasty, fenestration of the supracerebellar cyst in occlusive hydrocephalus using a semi-rigid needle neuroendoscope. The authors describe a child who, at the age of 1 month, was admitted to Neurosurgical Department No. 1 of the Federal Center for Neurosurgery of the Ministry of Health of the Russian Federation in Tyumen with a diagnosis of congenital internal occlusive hydrocephalus, subcompensated course. MRI scan of the brain: triventricular occlusive asymmetric hydrocephalus is visualized, adhesions in the upper parts of the aqueduct, supracerebellar arachnoid cyst were visualised. ETV, aqueductoplasty, fenestration of the supracerebellar cyst were performed. There were no postoperative neurological, endocrine and infectious complications. The observation period after surgery is 7 years from today. Conclusion: preoperative MRI analysis of the structures of the third ventricular floor, interventricular and prepontine cisterns is important for understanding endoscopic, microsurgical anatomy and surgical planning. The use of modern improved endoscopic instruments, low-traumatic performance of all stages of the operation allow to restore cerebrospinal fluid circulation and achieve high efficiency in the treatment of occlusive hydrocephalus in the long-term period. This, in turn, relieves patients of the shunt-dependent state, constant correction of the dysfunctions of the shunt system and long-term, and often ineffective, treatment performed by neurologists and pediatricians.
