Summary

This trial compares two common puncture sites—frontal region versus parietal eminence—for minimally invasive twist-drill drainage of chronic subdural hematoma (a slow brain bleed common in older adults). The goal is to see which site lowers the risk of the hematoma coming back and needing another surgery within three months. Adults with a unilateral chronic subdural hematoma who need surgical drainage are randomly assigned to one of the two puncture sites and followed for recovery and complications.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: twist-drill puncture and closed-system drainage at either the frontal region or the parietal eminence
What this could lead to: If one puncture site proves better, it could become the standard approach for this common brain-bleed surgery, lowering the chance that patients need a second operation.
What could go wrong: This is a single-center trial, so results may not apply everywhere. The outcome depends on surgical technique and patient anatomy, and recurrence can still happen regardless of site.
