About this study
Official title: Outcome of Chronic Subdural Hematoma: Double Burr Hole Versus Single Burr Hole With Subdural Drain Evacuation
The goal of this clinical trial is to compare the outcome of double burr hole versus single burr hole in patients of chronic subdural hematoma undergoing subdural drain evacuation.
The main questions it aims to answers are
Read more
- Which one of the surgical method i.e single burr hole or double burr hole is clinically superior with better post operative prognosis for the drainage of chronic subdural hematoma.
2 Compare the post operative complications in both the techniques in term of wound infection hospital stay duration , recurrence and mortality.
participants will be divided in two groups one group will be treated with single burr hole technique second group will be treated with double burr hole technique.
After procedure, patients will be followed-up in hospital until discharge and total hospital stay will be noted. Patients will be followed-up further in OPD . During follow-up, patients will be evaluated for wound infection, recurrence and mortality.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Single Burr hole CraniotomyProcedure or surgery
Single Burr hole made at the point of highest collection of hematoma in subdural space in brain.
Double Burr hole CraniotomyProcedure or surgery
Two burr hole made in skull each at parietal eminence and around superior temporal line to drain chronic subdural hematoma
| Study group | Role | What they receive |
|---|---|---|
| Double burr Hole Arm | Experimental | this arm includes patient who receive double burr hole craniotomy surgical procedure for drainage of chronic subdural hematoma Receives: Procedure: Double Burr hole Craniotomy |
| Single Burr Hole Arm | Experimental | this arm includes patient who receive single burr hole craniotomy surgical procedure for drainage of chronic subdural hematoma Receives: Procedure: Single Burr hole Craniotomy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Recurrence Of Chronic Subdural Hematoma
recurrence rate of chronic subdural hematoma evaluated if volume of sdh >15ml or significant mass effect on CT brain within 3 months post operatively
Measured: From date of surgery until radiologically confirmed recurrence (defined as subdural hematoma volume >15 mL or significant mass effect on CT brain) requiring repeat intervention, assessed up to 3 months postoperatively
quantity of hematoma evacuated
Intraoperatively evacuated hematoma quantity measured in millilitres and also includes the quantity obtained in subdural drain till 72 hours postoperatively
Measured: Measured intraoperatively at the time of surgery and cumulatively measured postoperatively from surgery until removal of the subdural drain, assessed up to 72 hours postoperatively.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recurrence Of Chronic Subdural Hematoma (time frame: From date of surgery until radiologically confirmed recurrence (defined as subdural hematoma volume >15 mL or significant mass effect on CT brain) requiring repeat intervention, assessed up to 3 months postoperatively). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
