What Is the Stellate Ganglion?
The stellate ganglion is a collection of sympathetic nerves located in the lower neck region.
These nerves are part of the sympathetic nervous system, which helps regulate certain involuntary functions throughout the body.
In selected pain conditions, sympathetic nerve activity may play a role in maintaining symptoms.
What Is a Stellate Ganglion Block?
A stellate ganglion block involves placing medication near the stellate ganglion.
The procedure may be used to temporarily interrupt sympathetic nerve activity and determine whether these nerves are contributing to pain.
Why Would a Patient Need One?
A physician may consider a stellate ganglion block when sympathetic nerve involvement is suspected.
The procedure may be considered for selected pain conditions involving areas such as the upper extremity.
The appropriate use depends on the patient’s individual diagnosis.
What Can Symptoms Look Like?
Depending on the condition, patients may report:
- Burning pain
- Sensitivity to touch
- Changes in skin temperature
- Changes in sweating
- Persistent upper-extremity discomfort
- Pain following an injury or other condition
Because these symptoms may have multiple causes, a careful evaluation is essential.
How Is the Procedure Performed?
The procedure is performed using image guidance to help the physician accurately identify the treatment area.
The skin is numbed before the needle is carefully positioned near the targeted nerve structure.
Medication is then administered.
Can It Be Used as a Diagnostic Tool?
Yes.
The response to a sympathetic nerve block can provide useful information about whether sympathetic nerve activity is contributing to a patient’s symptoms.
What Should Patients Know?
A stellate ganglion block is a specialized procedure and isn’t appropriate for every patient.
Your physician will consider your symptoms, medical history, medications, previous treatments, and overall health before determining whether the procedure is appropriate.
