The indications for the shunting of the patients with NPH are a matter of discussion. The measurement of the outflow resistance during the infusion test is one of the criteria for shunting. The authors present 38 patients with NPH in whom the lumbar constant-infusion test was carried out. The patients with the outflow resistance more then 13 mmHg/ml/min were selected for shunting. The results at least 4 months after operation are presented.
