The Impact of Programmable Valves on the Risk and Severity of Subdural Collections in Patients With Normal Pressure Hydrocephalus

Key Points

• This study aims to evaluate the effect of different programmable valve types on subdural collections in patients with normal pressure hydrocephalus.
• Large single-center cohort study
• Comparison of programmable valves (Certas and Strata) with Low Flow OSV
• Assessment of rates and severity of subdural collections
• Increased rate of subdural collections associated with Certas and Strata valves
• Severe complications more likely with certain programmable valve designs
• Low-flow designs may reduce risks for normal pressure hydrocephalus patients
