Fasciotomy is a surgery to relieve swelling and pressure in a compartment of the body. Tissue that surrounds the area is cut open to relieve pressure.
Fasciotomy is most often needed in the leg, but it may also be done in the arm, hand, foot, or abdomen.
Compartment Syndrome in Lower Leg

Muscles, nerves, and blood vessels are separated into areas called compartments. The compartments are wrapped in a strong sheet of tissue called fascia. Fluid buildup or swelling can increase pressure in the compartment. This can slow or block the flow of blood in the area and damages nerves. The loss of blood flow can also cause the death of tissue in the area. The pressure can also painfully squeeze tissue including nerves.
Fasciotomy is used to immediately release the pressure in these compartments. Releasing the pressure will improve blood flow and stop or slow damage to the local tissue. It may be used to treat:
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
Acute compartment syndrome and some of its causes are emergency situations. Surgery may need to be done right away to decrease damage.
If it is not a severe emergency, your doctor will examine the affected area thoroughly. Pressure will be measured in each compartment.
Tell your doctor about any medications you are taking, including herbal remedies or supplements.
You may be given:
There may be some differences in how a fasciotomy is done based on the part of the body and severity.
In general, the procedure is similar for a leg or arm. One incision will be made in the skin over the compartments. The incision will cover the length of the limb between 2 joints. The fascia, just under the skin, is then cut in the same length. If dead tissue is present it will be removed.
Loose stitching will be placed over the area but the wound will remain open. The doctor will gradually close the wound once the swelling has passed.
Until the wound is closed, the area will be wrapped in a dressing. The wound will be monitored with frequent trips to the operating room to have:
Complete closure may take up to 2 weeks. A skin graft may be needed if the area cannot be completely closed.
You will be taken to the recovery room and monitored.
The length of the procedure will depend on how much damage there is.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
You may be in the hospital for up to 3 days. If you have any problems, you may need to stay longer.
Right after the procedure, you will be in a recovery room where your blood pressure, pulse, and breathing will be monitored. Recovery may also include:
You will also be shown how to use supportive devices like crutches or a sling.
During your stay, the hospital staff will take steps to reduce your chance of infection such as:
There are also steps you can take to reduce your chances of infection such as:
You will not be able to use the affected limb. Supportive devices, like a splint or crutches, will be needed to support the limb during recovery.
Contact your doctor if your recovery is not progressing as expected or you develop complications such as:
If you have signs of acute compartment syndrome or you think you have a different emergency, call for emergency medical services right away.
