Study: NCT06629168

Intervention type: DIAGNOSTIC_TEST
Intervention: External lumbar drainage
Description: External lumbar drainage placement for assessing responsivity of external derivation of cerebrospinal fluid. It is test of responsivity to ventriculo-peritoneal shunt placement

Intervention type: PROCEDURE
Intervention: Ventriculo-peritoneal shunt placement
Description: Surgical procedure based on implantation a thin catheter into brain lateral ventricle (placed through a burrhole from Kocher point) and connection to prechamber and valve (placed behind the ear under skin) and similar thin catheter pushed under skin of neck, chest and abdomen (where put intraperitoneally). Telemetric prechamber placement according the randomization (www.randomization.com) and the envelope method of choosing of patients.

Intervention type: DIAGNOSTIC_TEST
Intervention: Telemetric prechamber reading
Description: Non-invasive reading of telemetric prechamber made during each follow-up control.

Intervention type: OTHER
Intervention: Valve setting change
Description: Changing of valve setting according patient's actual condition. Decission based on clinical state, radiological finding on CT and values readed from telemetric prechamber. Timing - each follow-up control.
