S06.5 Traumatic subdural hemorrhage

Name of the Condition

• Traumatic subdural hemorrhage

Summary

A traumatic subdural hemorrhage is a type of intracranial injury where blood accumulates between the dura mater (the outermost protective membrane of the brain) and the brain itself, resulting from trauma. This condition may cause increased intracranial pressure and neurological symptoms depending on the size and location of the bleed.

Causes

Physical trauma to the head is the primary cause, such as from falls, motor vehicle accidents, or assaults. The bleeding occurs when blood vessels rupture due to the force of impact, allowing blood to collect in the subdural space.

Risk Factors

• Older age, as brain atrophy increases the risk of vessel tearing.
• Use of anticoagulant or antiplatelet medications, which can worsen bleeding.
• Alcohol abuse, which may lead to falls or impaired judgment.
• Previous head injuries, which can weaken blood vessels over time.

Symptoms

• Headache, often severe or worsening.
• Nausea or vomiting.
• Dizziness, confusion, or altered mental status.
• Weakness or numbness in limbs.
• Seizures.
• Unequal pupil size or vision changes.

Diagnosis

Diagnosis typically involves a CT scan to detect the hemorrhage and assess its size. An MRI may be used for further evaluation. Neurological examinations are performed to assess cognitive and motor function, and patient history is reviewed for trauma.

Treatment Options

• Observation for small, stable bleeds with close monitoring.
• Medications to control swelling, seizures, or pain.
• Surgical intervention, such as craniotomy or drainage, for larger or symptomatic bleeds.
• Rehabilitation therapy to address neurological deficits.

Prognosis and Follow-Up

Prognosis depends on the severity of the hemorrhage, patient age, and promptness of treatment. Mild cases may resolve with observation, while severe cases can lead to long-term disability or death. Follow-up includes imaging to monitor healing and neurological assessments.

Complications

• Increased intracranial pressure, potentially causing brain damage.
• Seizures or epilepsy.
• Cognitive or motor function impairment.
• Recurrent bleeding.
• Death in severe cases.

Lifestyle & Prevention

• Wear protective headgear during high-risk activities (e.g., sports, construction).
• Avoid excessive alcohol use to reduce fall risk.
• Manage chronic conditions (e.g., hypertension) that may increase bleeding risk.
• Follow safety guidelines to prevent head injuries (e.g., fall-proofing homes).

When to Seek Professional Help

Seek immediate medical attention if experiencing severe headache, confusion, vomiting, seizures, or loss of consciousness after head trauma. Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

Document the type of trauma (e.g., fall, accident) and any associated symptoms (e.g., loss of consciousness, neurological deficits) to support coding. Include details on imaging findings (e.g., CT results) and treatment provided. Ensure documentation aligns with the clinical presentation to accurately reflect the condition.
