Stellate ganglion block
The stellate ganglion is a group of sympathetic nerves in the front of the neck. A block here may be used for complex regional pain syndrome (CRPS) and other sympathetically maintained pain affecting the arm, hand, head, or face. Afterward, it is common to notice temporary effects on the same side, such as a droopy eyelid, redness of the eye, warmth in the arm or hand, a stuffy nose, or a hoarse voice. These usually wear off within hours.
Lumbar sympathetic block
This block targets sympathetic nerves alongside the lower spine. It may be used for CRPS or nerve-related pain in a leg or foot, and some circulation-related pain. Warmth in the treated leg afterward is expected.
Celiac plexus block
The celiac plexus is a network of nerves in the upper abdomen that carries pain signals from organs such as the pancreas, liver, and stomach. A celiac plexus block may help with chronic abdominal pain from conditions such as chronic pancreatitis or pancreatic and other abdominal cancers. Temporary lightheadedness from lower blood pressure and changes in bowel habits can occur afterward.
What to expect
- These blocks are performed as outpatient procedures using X-ray or ultrasound guidance.
- Relief may last longer than the numbing medicine itself, and a series of blocks is sometimes recommended.
- Because these blocks can affect blood pressure and coordination briefly, you will rest in recovery before going home and will need a driver.
Preparing for your procedure
- Tell us about every medication you take, especially blood thinners (for example warfarin, apixaban, clopidogrel, or daily aspirin). Do not stop a blood thinner on your own — we will coordinate with the doctor who prescribes it.
- Let us know if you have diabetes, an allergy to contrast dye, iodine, latex, or local anesthetics, or if you may be pregnant.
- If you will receive sedation, plan on having an adult drive you home.
- Call us if you develop a fever or infection before your procedure date.
Risks
All procedures carry some risk. Depending on the treatment, possible risks can include soreness or bruising where the needle was placed, bleeding, infection, a temporary rise in pain, allergic reaction to a medication, and, rarely, nerve injury. If a steroid is used, some people notice short-term flushing, trouble sleeping, or higher blood sugar. Your provider will go over the specific risks, benefits, and alternatives for your situation before you decide.
