About this study

This study aims to evaluate and compare the clinical and radiological outcomes of patients with chronic subdural hematoma (CSDH) undergoing surgical evacuation using either single or double burr-hole craniostomy.

The comparison focuses on key outcome measures including recurrence rate, postoperative complications, neurological improvement, length of hospital stay, and overall functional recovery, in order to determine the most effective and safe surgical technique.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Chronic Subdural Hematoma EvacuationProcedure or surgery

    Single burr-hole technique: A single burr hole was made over the maximum thickness of the hematoma followed by dural opening, irrigation with warm saline, and placement of a drain.

    Double burr-hole technique: Two burr holes were created (frontal and parietal), allowing more extensive irrigation and evacuation of the hematoma, followed by drain placement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recurrence

    re-accumulation requiring re-operation

    Measured: 6 months

Secondary outcomes (5)
  1. Infection

    invasion and multiplication of pathogenic microorganisms in a host, causing a local or systemic immune response, which may or may not result in clinical disease.

    Measured: 6 months

  2. Seizures

    sudden, uncontrolled electrical disturbance in the brain that can cause changes in behavior, movement, sensation, consciousness, or autonomic function

    Measured: 6 months

  3. Pneumocephalus

    presence of air within the intracranial cavity

    Measured: 6 months

  4. Glasgow Coma Scale

    evaluate the level of consciousness in patients with acute brain injury by assessing three components: eye opening, verbal response, and motor response.score ranges from 3 to 15, with lower scores indicating more severe impairment of consciousness.

    Measured: 6 months

  5. Motor Power

    strength generated by voluntary contraction of a muscle or muscle group and is assessed during neurological examination to evaluate the integrity of the motor system. It is commonly graded using the Medical Research Council (MRC) Muscle Strength Scale.ranging from 0 (no contraction) to 5 (normal strength), with higher vlaues indicating better outcomes.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Chronic Subdural Hematoma Evacuation in people with Chronic Subdural Hematoma, run by Sohag University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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 (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07688473, which also lists 2 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2026.
