A chronic subdural hematoma (CSDH) is a slow build-up of old blood between the brain and its outer covering, most common in older adults. Burr-hole surgery, performed at India's leading neurosurgery centres, offers rapid symptom relief.
A chronic subdural hematoma is a collection of old, often liquefied blood that gradually forms beneath the dura (the brain's outer membrane), usually following a minor head injury that may have been forgotten — particularly common in elderly patients and those on blood-thinning medication. As it enlarges, it can press on the brain, causing headache, confusion, weakness on one side, or drowsiness.
The standard treatment is a burr-hole craniostomy: one or two small holes are drilled in the skull under local or general anaesthesia, and the old blood is drained with a temporary drain left in place for a day or two to reduce recurrence. It is a quick, well-tolerated procedure even in elderly patients.
| Outcome Measure | Reported Rate |
|---|---|
| Favourable outcome (adjusted for baseline health) | Comparable across age groups |
| Overall recurrence rate | ~12.8% after burr-hole + drainage |
| Key risk factor for recurrence | Pre-operative blood-thinning medication |
