What is Hematoma?

A hematoma is a medical condition characterised by a localised collection of blood outside the blood vessels, usually in liquid form within a tissue. This blood collection can occur anywhere in the body and varies from tiny (petechiae) to large (ecchymosis).

Hematomas are a typical result of injury to the blood vessels, and they can occur in many different areas of the body. Understanding the nature, causes, types, symptoms, diagnosis, and treatment of hematomas is crucial for medical professionals and patients.

While hematomas can be painful and cause significant discomfort, they are not usually life-threatening. However, in some cases, a hematoma can lead to severe complications, such as infection or tissue damage, and may require medical intervention.

The 5 Types of Hematomas

There are several hematomas, each with specific characteristics and potential complications. These include subdural, epidural, intracerebral, subungual, and intramuscular hematomas. Each hematoma type highlights the body's vulnerability to injury and the complex nature of our vascular and tissue systems.

  • Subdural Hematomas: Found between the brain's dura mater and arachnoid mater, these are typically the result of a head injury. They can exert pressure on the brain, necessitating prompt attention.
  • Epidural Hematomas: Occurring between the skull and dura mater, they're often linked to skull fractures. Rapid intervention is crucial to manage the potential for severe brain injury.
  • Intracerebral Hematomas: Situated within the brain tissue, these can arise from strokes or traumatic brain injuries. They are painful conditions that can affect brain function and require immediate medical care.
  • Subungual Hematomas: These form under a nail, usually due to minor injuries like slamming a finger into a door. While painful, they're often less severe and can be treated with rest and, if necessary, minor medical procedures to relieve pressure.
  • Intramuscular Hematomas: These develop within muscle tissue and can result from injury or strenuous activity. Treatment typically involves resting, icing, compression, and elevating the affected area.

The 6 Most Common Causes of Hematomas

Hematomas are most commonly caused by injury, such as a fall, car accident, or sports injury. However, they can also be caused by medical procedures, such as surgery or invasive diagnostic procedures. 

Acknowledging these causes is vital for prevention and effective treatment, including adjusting medications or modifying lifestyle choices to mitigate risks.

  • Injury: The primary cause, including falls, car accidents, or sports-related impacts, leading to damaged blood vessels.
  • Medical Procedures: Surgical operations or invasive diagnostic tests can inadvertently cause blood vessels to rupture.
  • Blood Clotting Disorders: Conditions affecting blood's ability to clot can heighten hematoma risks, necessitating careful management of these disorders.
  • Ageing: Fragility in blood vessels increases, making older adults more susceptible to hematomas, even from minor injuries.
  • Medications: Anticoagulant medication or blood thinners can amplify the risk, as they impair the blood's clotting ability.
  • Lifestyle Factors: Alcohol consumption and smoking may weaken blood vessel walls or affect clotting, contributing to hematoma formation.

How Do You Recognise Hematomas?

Recognising a hematoma can be challenging, as the symptoms can vary depending on the location and size of the hematoma. However, common symptoms include pain, swelling, and skin discolouration. 

In severe cases, a hematoma can cause confusion, loss of consciousness, or difficulty moving a part of the body.

If you suspect that you or someone else has a hematoma, it is vital to seek medical attention immediately. A healthcare professional can perform a physical examination and may order imaging tests, such as an ultrasound or CT scan, to confirm the diagnosis and determine the severity of the hematoma.

Visual and Physical Indications

A hematoma often presents a noticeable discolouration—ranging from red to purple to black—on the skin, indicating blood accumulation beneath. The area may swell, feel warm, and exhibit tenderness or pain, particularly when pressure is applied or during movement. These signs help in identifying superficial hematomas.

Symptoms of Deep Hematomas

External signs may not be as apparent for hematomas situated more profoundly within the body, such as in the abdominal cavities or brain. Symptoms could include pain in the affected area.

Still, severe cases might lead to more alarming signs like confusion, dizziness, loss of consciousness, or paralysis, underscoring the need for urgent medical care.

Diagnostic Techniques

Upon suspecting a hematoma, healthcare professionals conduct a thorough physical exam. They may use diagnostic tests to confirm the presence and assess the severity of a hematoma.

Imaging tests like ultrasound, CT scans, or MRIs are instrumental in visualising the extent and exact location of the hematoma, facilitating a tailored treatment approach. Blood tests might also be performed to uncover any clotting disorders that could contribute to hematoma formation.

How Do You Treat Hematomas?

The treatment for a hematoma depends on its size, location, and the patient's overall health. Small hematomas not causing significant symptoms may not require treatment and may resolve independently. However, larger hematomas or those causing significant symptoms may require treatment.

Treatment options for a hematoma may include rest, ice, compression, elevation (RICE), pain medication, physical therapy, and, in some cases, surgery. Treatment aims to relieve symptoms, prevent complications, and promote healing.

Conservative Care

For more minor hematomas causing minimal symptoms, a conservative approach often suffices. This includes the RICE method—resting, icing, compressing, and elevating the affected area—to mitigate swelling and discomfort.

Additionally, over-the-counter pain relievers like acetaminophen or ibuprofen can alleviate pain. At the same time, physical therapy may be advised to restore function and strength.

Aspiration for Hematoma Relief

When a hematoma is particularly bothersome or persistent, aspiration might be recommended. This procedure, conducted under local anaesthetic, involves using a needle to extract accumulated blood, offering prompt symptom relief and speeding up the healing process.

Surgical Intervention

Large or symptomatically significant hematomas may require surgical intervention to remove accumulated blood and repair damaged vessels. The nature of the surgery depends on the hematoma's location.

For example, subdural hematomas might require a craniotomy to relieve pressure on the brain. In contrast, intramuscular hematomas could be addressed with a fasciotomy to ease muscle compartment pressure.

How Do You Prevent Hematomas?

Minimising the risk of hematomas involves a combination of protective strategies, health management, and lifestyle adjustments. While not all hematomas can be avoided, these measures can significantly reduce their likelihood.

Implement Protective Measures

Adopting safety precautions during physical activities and daily life is crucial in preventing injuries that could lead to hematomas. This includes:

  • Wearing appropriate protective gear during sports or recreational activities to shield against impacts.
  • Practising safe driving habits and ensuring the use of seat belts
  • Implementing fall-prevention strategies, especially for older adults, such as securing rugs, improving home lighting, and using assistive devices.

Manage Underlying Health Conditions

Effectively controlling health conditions that could predispose an individual to hematomas is essential. This may involve:

  • Regular monitoring and treatment of blood clotting disorders to maintain optimal clotting function.
  • Managing blood pressure and diabetes to protect blood vessel integrity and prevent complications that could lead to hematoma formation.
  • Adjusting medications under a healthcare provider's guidance, particularly if taking anticoagulants or blood thinners, to balance the benefits with the risk of excessive bleeding.

Maintain a Healthy Lifestyle

A holistic approach to health can fortify the body's defences against hematoma formation:

  • A balanced diet rich in vitamins and minerals supports blood vessel health and overall well-being.
  • Engaging in regular physical activity strengthens the body and can improve circulation.
  • Avoiding smoking and limiting alcohol intake are vital for maintaining the strength and resilience of blood vessels.

Braving the Bruise

Hematomas are a common medical condition characterised by local blood collection outside the blood vessels. They can occur anywhere in the body and vary from tiny to large.

While hematomas can be painful and cause significant discomfort, they are not usually life-threatening. However, in some cases, they can lead to severe complications and may require medical intervention.

Understanding the nature, causes, types, symptoms, diagnosis, and treatment of hematomas is crucial for medical professionals and patients.

Taking steps to prevent injury, manage underlying conditions, and live a healthy lifestyle can reduce the risk of developing a hematoma and promote overall health and well-being.
