Subdural Hematoma Hemorrhage: Causes & Treatment
Subdural Hematoma Hemorrhage: Causes & Treatment A subdural hematoma hemorrhage is a serious brain injury. It happens when blood bleeds under the brain’s outer layer. It’s very dangerous and needs quick action to save lives.
This condition is a type of intracranial hemorrhage. It’s when blood gathers under the dura mater, the brain’s outer layer. Knowing how to treat it is key to helping patients get better.
It’s important to understand this brain injury well. We’ll look at what causes it and how it’s treated. We’ll use trusted sources like the Mayo Clinic and the National Institute of Neurological Disorders and Stroke.
What is a Subdural Hematoma Hemorrhage?
A subdural hematoma happens when bleeding forms between the brain and its outer covering, the dura mater. It often comes from a head injury. Knowing about subdural hematoma types helps us understand their effects.
Definition and Overview
A subdural hematoma is blood that gathers outside the brain but inside the skull. It happens when blood vessels in the subdural space get damaged from a head injury. Johns Hopkins Medicine says this can put pressure on the brain, causing serious problems. Quick action is key to lessen damage from the bleeding.
Difference Between Acute and Chronic Subdural Hematomas
There are two kinds of subdural hematomas: acute and chronic. Each has its own timing, symptoms, and risks.
| Characteristics | Acute Subdural Hematoma | Chronic Subdural Hematoma |
|---|---|---|
| Onset | Rapid, usually within 72 hours of head injury | Slow, developing over weeks or months |
| Symptoms | Severe headaches, confusion, drowsiness, and unconsciousness | Gradual headaches, cognitive impairment, and mild confusion |
| Potential Complications | Brain herniation, increased intracranial pressure, and death | Progressive neurological deficits and persistent headaches |
Subdural Hematoma Hemorrhage: Causes & Treatment Understanding both acute and chronic subdural hematomas helps doctors treat them better. Cleveland Clinic says it’s vital to know the differences for the right treatment.
Understanding the Anatomy of the Brain Related to Hematomas
To understand subdural hematomas, we must look closely at brain anatomy. The brain is covered by layers called the meninges. These layers are key to keeping the brain safe and healthy. They can also be affected by cerebral hemorrhage.
Layers of the Meninges
The meninges have three main layers:
- Dura Mater: The outermost layer, thick and strong, protects the brain well.
- Arachnoid Mater: Underneath the dura mater, this layer is like a web. It cushions the brain.
- Pia Mater: The innermost layer, it sticks to the brain’s surface. It supports and feeds the brain.
Together, these layers protect the brain from hits and infections. If a brain bleed happens, like in subdural hematomas, it often affects these layers.
Function of the Subdural Space
The subdural space is between the dura mater and the arachnoid mater. It’s usually small but can get bigger if there’s bleeding. This can lead to subdural hematomas. Knowing about this space and its role is important.
It’s where blood gathers during a bleed. This blood can press on the brain, causing serious health issues.
Common Causes of Subdural Hematoma Hemorrhages
Subdural hematoma hemorrhages come from many things. Knowing what causes them helps with quick treatment. We’ll look at common causes, from injuries to medical conditions that make people more likely to get this.
Traumatic Brain Injuries
Traumatic brain injuries (TBIs) are a top reason for subdural hematomas. They happen from falls, car crashes, or being hit. A big hit to the head can make blood vessels break and bleed in the brain.
This bleeding puts pressure on the brain and can cause big problems.
Medical Conditions That Can Lead to Hematomas
Some medical conditions make getting a subdural hematoma more likely. People taking blood thinners are at higher risk because these medicines stop blood from clotting. This makes bleeding worse.
Older people with cerebral atrophy are also at risk. This condition makes the brain more fragile and easy to hurt. Also, problems after brain surgery can cause or make subdural hemorrhages worse.
Studies in ‘The Lancet’ and ‘Archives of Physical Medicine and Rehabilitation’ highlight how important these risk factors are. Subdural Hematoma Hemorrhage: Causes & Treatment
Signs and Symptoms to Watch Out For
It’s key to spot the signs of a subdural hematoma early. Look out for a headache that gets worse over time. You might also notice trouble moving or muscles feeling weak.
Changes in how you think can be signs too. This includes trouble remembering things, feeling confused, or making poor choices. These cognitive changes can start slowly but get worse fast. You should get help right away. Subdural Hematoma Hemorrhage: Causes & Treatment
Watch for signs of altered consciousness too. This means feeling very sleepy or even not waking up at all. It means your brain might be under a lot of pressure and you need help fast.
Other signs include feeling sick to your stomach, throwing up, or having trouble with talking or seeing. If you notice any of these, get medical help quickly to prevent more serious problems.

How Subdural Hematomas Are Diagnosed
Doctors use special tests and scans to find subdural hematomas. They look at brain images and check the patient’s health closely. This helps them know what to do next.
Imaging Techniques
Diagnostic imaging is key for checking on subdural hematomas. Doctors often use CT scan and MRI to see the brain clearly. A CT scan is fast and great for finding bleeding quickly. An MRI takes longer but shows more details, especially for small or tricky hematomas. Subdural Hematoma Hemorrhage: Causes & Treatment
| Imaging Technique | Advantages | Limitations |
|---|---|---|
| CT Scan | Fast, widely available, excellent for detecting acute bleeding | Less detailed than MRI for soft tissues |
| MRI | Highly detailed, excellent for soft tissues and chronic conditions | More time-consuming, less accessible than a CT scan |
Clinical Evaluations by Physicians
Doctors also do a neurological examination to check on patients. They look at how well the brain and nerves are working. They test reflexes, muscle strength, and how well the body moves and senses things.
This helps doctors see how bad the damage is and what treatment is needed. Using diagnostic imaging and these tests together helps doctors make good plans for treatment.
Treatment Options for Subdural Hematoma Hemorrhages
Subdural hematoma hemorrhages need quick medical help to stop more problems and help healing. There are two main ways to treat this: surgery and non-surgery methods.
Surgical Interventions
Surgery for subdural hematoma includes craniotomy and burr hole surgery. Craniotomy means taking off a part of the skull to get to the blood clot and ease brain pressure. Burr hole surgery is a small surgery where holes are made in the skull to drain the blood. The choice depends on the patient’s health, the size and place of the blood clot.
The American College of Surgeons says surgery has its own success rates and risks. Craniotomy works well for big blood clots but can lead to infections or more bleeding. Burr hole surgery is better for small clots and weak patients because it’s less invasive and has faster recovery.
Non-surgical Management
Subdural Hematoma Hemorrhage: Causes & Treatment For some patients, not needing surgery right away, non-surgery treatment is an option. This includes using medicine and watching the brain pressure. Medicine therapy helps with headaches, seizures, and swelling. Doctors might use steroids, seizure drugs, and painkillers.
ICP monitoring is key when brain pressure is a worry. It checks the skull pressure to help doctors adjust treatments. This way, the brain works right and avoids more harm.
Using medicine and ICP monitoring together makes a good plan for non-surgery care. It helps keep patients stable and on the road to recovery.
| Aspect | Craniotomy | Burr Hole Surgery | Non-Surgical Management |
|---|---|---|---|
| Indication | Large Hematomas | Small Hematomas | Stable Condition, ICP Issues |
| Procedure | Open Skull | Drill Small Holes | Medication, ICP Monitoring |
| Recovery Time | Longer | Shorter | Varies |
| Risks | Higher | Lower | Minimal |
Recovery and Rehabilitation Post-Treatment
Getting better from a subdural hematoma takes more than just medical help. It’s about getting back your strength, your mind, and your happiness. This part talks about the main parts of getting better, like rehab exercises, cognitive therapy, and support groups.
Physical Therapy
Physical therapy is key to getting your body back in shape after treatment. The American Physical Therapy Association says it’s important to have rehab exercises that fit what you need. Some exercises you might do are: Subdural Hematoma Hemorrhage: Causes & Treatment
- Range-of-motion exercises
- Balance and coordination drills
- Strength training programs
Going to physical therapy often helps make your muscles less stiff. It makes moving easier and makes you feel better overall.
Mental and Emotional Recovery
Getting your mind and feelings back on track is just as important. Cognitive therapy and being in support groups help a lot with this. ‘Rehabilitation Psychology’ says good mental health plans include:
- Cognitive therapy sessions to help with memory, focus, and solving problems.
- Mindfulness and stress management to lower anxiety and sadness.
- Being in support groups to talk and get support from others who understand.
Putting these things together in neurorehabilitation helps you get better fully. It looks after your body and mind. Regular check-ins with doctors, changing your therapy as needed, and having a caring home helps too.
Preventive Measures to Reduce Risk
To prevent subdural hematoma hemorrhages, we need to do many things. This includes preventing falls, using safety gear, watching anticoagulant levels, and making lifestyle changes. For older people, stopping falls is very important.
Changing your home can help a lot. Put in grab bars, make sure there’s good lighting, and get rid of things that could trip you. This can really lower the chance of getting hurt.
Wearing safety gear like helmets when you’re biking or working on a construction site can also protect you. The Centers for Disease Control and Prevention (CDC) says helmets are a key way to stop brain injuries.
If you’re on blood thinners, it’s crucial to keep an eye on your levels. Doctors should check your medicine and change it if needed. Eating well, not drinking too much alcohol, and staying active can also help keep your brain healthy.
Following advice from groups like the World Health Organization (WHO) can help too. By doing all these things, you can greatly reduce your risks and stay safe.
