A craniotomy for hematoma evacuation is a surgical procedure used to remove blood that has collected in or around the brain. The goal is to relieve pressure on the brain, prevent further injury, and improve neurologic function.
Quick Facts:
- Used to treat serious bleeding in or around the brain
- Often performed urgently or emergently
- Relieves pressure caused by blood clot buildup
- May be lifesaving in the right situation

WHAT IS A CRANIOTOMY FOR HEMATOMA EVACUATION?
A hematoma is a collection of blood that forms when bleeding occurs in or around the brain. When enough blood builds up, it can compress brain tissue and increase pressure inside the skull.
A craniotomy for hematoma evacuation is a procedure in which a section of skull is temporarily opened so the blood clot can be removed.
This surgery may be performed for:
- Intracerebral hemorrhage
- Subdural hematoma
- Epidural hematoma
- Other collections of blood causing pressure on the brain
WHY IS THIS PROCEDURE PERFORMED?
This procedure is performed when bleeding in or around the brain is causing dangerous pressure, neurologic symptoms, or worsening brain injury.
Common Reasons for Surgery
- Large hematoma causing mass effect
- Neurologic decline
- Increasing pressure in the brain
- Midline shift on imaging
- Failure of non-surgical management
👉 The goal is to remove the clot, relieve pressure, and protect the brain
WHO IS A CANDIDATE?
Patients may be candidates for surgery if:
- The hematoma is large or causing significant compression
- Symptoms are worsening
- There is decreased alertness or neurologic deficit
- Imaging shows mass effect or midline shift
- Surgery is likely to improve outcome or prevent deterioration
Decision-making depends on:
- Location of the bleed
- Size of the hematoma
- Age and overall health
- Neurologic condition at presentation
- Cause of the bleeding
HOW THE PROCEDURE IS PERFORMED
Step-by-Step Overview
- Anesthesia
- The procedure is performed under general anesthesia
- Craniotomy
- A portion of the skull is temporarily removed to access the clot
- Hematoma Evacuation
- The blood clot is carefully removed
- Active bleeding is identified and controlled when possible
- Relief of Pressure
- Removing the clot reduces pressure on the brain
- Closure
- In many cases, the skull is replaced and secured
- In some situations with severe swelling, part of the skull may be left off temporarily
OUR APPROACH
Our focus on rapid evaluation, careful judgment, and timely intervention.
- Not every hematoma requires surgery
- The decision depends on the patient’s condition, imaging, and likelihood of benefit
- When surgery is needed, the goal is to relieve pressure safely while minimizing additional injury
- Care is coordinated closely with ICU, trauma, stroke, and hospital teams as needed
👉 Thoughtful timing and patient selection are critical to good outcomes
WHAT TO EXPECT
Before Surgery
- Emergency evaluation and brain imaging
- Review of neurologic condition and medical history
- Discussion with family when possible regarding risks and goals
Day of Surgery
- Often performed urgently or emergently
- Procedure length depends on the size and location of the hematoma
Hospital Stay
- ICU care is often required after surgery
- Monitoring includes neurologic exams, repeat imaging, and management of brain swelling
Recovery
- Recovery varies widely depending on the severity of the bleed
- Some patients recover quickly, while others require prolonged rehabilitation
- Follow-up imaging and office visits are often needed
OUTCOMES & SUCCESS RATES
Outcomes depend on:
- Type of hematoma
- Size and location of bleeding
- Speed of treatment
- Neurologic status before surgery
- Patient age and medical condition
Potential Benefits of Surgery
- Relief of dangerous pressure on the brain
- Prevention of further neurologic decline
- Improved survival in appropriate cases
- Better opportunity for recovery when performed at the right time
RISKS & COMPLICATIONS
As with any brain surgery, risks include:
- Re-bleeding
- Infection
- Stroke
- Seizures
- Brain swelling
- Persistent neurologic deficits
- Need for additional surgery
👉 These risks are weighed carefully against the danger of leaving the hematoma untreated
FREQUENTLY ASKED QUESTIONS
Is this surgery always an emergency?
Often yes, but not always. Some hematomas can be monitored, while others require immediate surgery.
Will surgery reverse the brain injury?
Surgery relieves pressure and prevents further damage, but recovery depends on the severity of the original injury or bleeding.
How long is recovery?
Recovery can range from days to months depending on the extent of the hemorrhage and the patient’s overall condition.
Will the blood come back after surgery?
Sometimes bleeding can recur, which is why close monitoring and follow-up imaging are important.
