Acute Compartment Syndrome
En Español (Spanish Version)

Definition
Sheets of connective tissue called fascia are located under the skin of the arms and legs. These wrap around groups of muscles, nerves, and blood vessels to create a unit called a compartment. When pressure builds up in these enclosed spaces, it is redirected into the compartment. When pressure reaches a certain point, it disrupts blood flow. Blood vessels may fail and tissue dies. Acute compartment syndrome (ACS) can affect the arms, hands, legs, feet, and buttocks.

Causes
Common causes include:

  • Vein obstructions in the extremities
  • Hemorrhage
  • Complication of surgery
Risk Factors
These factors increase your chance of developing ACS:

  • Pre-existing condition that could lead to fatal bleeding in cases of trauma, such as:
    • Taking anticoagulants
    • Having a bleeding disorder such as hemophilia
  • Participation in certain collision or contact sports such as football
  • Bandages or casts that are worn too tightly or worn for too long
  • Recent injury to the area
  • Burns
  • Swelling of tissues under the skin
Symptoms
Symptoms may include:

  • Severe pain
  • Feeling of tightness or fullness of muscles
  • Swollen, pale, shiny skin over affected area
  • Numbness or tingling
Symptoms can develop within 30 minutes to two hours. In other cases, it may take days.

ACS is an emergency. Get medical help right away. Damage can result in serious injury or even death.

Diagnosis
You will be asked about your symptoms and medical history. A physical exam will be done.

Images may be taken of your bodily structures. This can be done with:

The pressure inside your compartments will be measured. This can be done with:

  • Slit catheter
  • Tonometer
  • Near-infrared spectroscopy
Your bodily fluids will be tested. This can be done with blood tests.

Treatment
Surgery to relieve pressure, called fasciotomy, must be done right away to prevent permanent damage. The doctor makes a long cut into the fascia to open the envelope of tissue and relieve pressure.

Prevention
ACS is difficult to prevent because there are many causes. But there are some steps you can take to reduce your risk of injury, such as:

  • Wearing proper equipment when playing sports
  • Making sure that your medical records mention if you have used anticoagulants or if you have blood diseases
  • Being aware of the risk of ACS when you are wearing a bandage or cast
