Brief Summary

Endoscopic Third Ventriculostomy for Adults with Hydrocephalus: Creating a Prognostic Model for Success - A Retrospective Multicenter Study Background: Endoscopic third ventriculostomy (ETV) is becoming an increasingly widespread treatment for hydrocephalus, but most of the research is based on paediatric populations. The ETV Success Score (ETVSS) was developed in 2009 to predict the outcome of ETV in children. There is no similar tool for predicting outcome in adults. Objective: The purpose of this study is to create a prognostic model to predict the success of ETV for adult patients with hydrocephalus Methods: The study will adhere to the TRIPOD reporting guidelines and will be conducted as a retrospective chart review of all patients ≥18 years old treated with ETV at the participating centres between Jan 1st, 2010 and Dec 31st, 2018. Data collection is conducted locally in REDCap. Univariate analyses will be used to identify several strong predictors to be included in a multivariate logistic regression model. The model will be validated using K-fold cross validation. Discrimination will be assesses using AUROC and calibration with calibration belt plots. Expected outcomes: The ability to predict who will benefit from an ETV will allow better primary patient selection both for ETV and shunting. This would reduce additional second procedures due to primary treatment failure. A success score specific for adults could also be used as a communication tool to provide better information and guidance to patients.

Outcome Measures

Primary Outcomes (1)

  • ETV success

    The procedure is considered successful if the patient experience clinical improvement at first follow up and receives no further CSF diversion procedures, within one year of the initial procedure.

    Evaluated 1 year after operation

Secondary Outcomes (2)

  • ETV survival

    From procedure to latest documented follow-up, adressed up to 31 dec. 2020.

  • ETV related adverse events

    Up to 3 months after operation.

Study Population

The study population is all first time ETV performed at the participating centres between January 1st 2010 and December 31st 2018.

You may qualify if:

  • ETV procedure performed
  • ≥18 years old at time of first ETV

You may not qualify if:

  • \<18 years old at time of first ETV
  • Permanent intraventricular foreign bodies left behind after the ETV. eg. Shunt or stents. Temporary external ventricular drains, ICP-monitoring probes or ligated shunts where the ventricular drain is removed, are not excluded.
