Summary
This study introduces an intraoperative scale to predict endoscopic third ventriculostomy (ETV) failure in hydrocephalus treatment. Key intraoperative findings significantly correlate with ETV success or failure, aiding surgical planning.
Area of Science:
- Neurosurgery
- Medical Technology
- Clinical Research
Background:
- Endoscopic third ventriculostomy (ETV) is a common treatment for hydrocephalus.
- Predicting ETV success is crucial for patient outcomes.
- Numerous factors may influence ETV success or failure.
Purpose of the Study:
- To analyze preoperative and intraoperative risk factors for ETV failure.
- To develop an intraoperative scale for predicting ETV failure.
Main Methods:
- A retrospective analysis of 51 patients (27 adults, 24 children) who underwent ETV.
- Assessment of intraoperative video records for specific findings.
- Development and application of a 0-6 point intraoperative scale.
Main Results:
- A higher score on the intraoperative scale significantly correlated with ETV failure (p < 0.0001).
- Absence/weakness of third ventricle floor pulsation (p < 0.0001), thickened subarachnoid membranes (p < 0.04), and Liliequist membrane opening (p < 0.008) were linked to failure.
Conclusions:
- Intraoperative factors are critical for predicting ETV success.
- The developed scale shows promise in identifying patients at higher risk of ETV failure.
- Further research with larger cohorts is needed to fully elucidate the impact of all intraoperative factors.
