What is a CT-Guided Cervical Nerve Block?

A CT-guided cervical nerve block is a procedure that uses computed tomography (CT) imaging to help a doctor precisely place a needle near specific nerves in your neck (cervical spine). Once the needle is in the correct position, anesthetic and sometimes anti-inflammatory medication is injected to block pain signals or reduce inflammation around the nerve.

Why is this procedure done?

This procedure is performed for several reasons: (1) To diagnose the source of neck, shoulder, or arm pain by temporarily numbing specific nerves to see if pain is relieved; (2) To treat chronic pain conditions such as cervical radiculopathy (pinched nerve), neck pain, or certain types of headaches; (3) To reduce inflammation around irritated nerves; (4) As an alternative to surgery for pain management.

How should I prepare for the procedure?

Before the procedure, inform your doctor about all medications you are taking, especially blood thinners (like warfarin, aspirin, or clopidogrel). You may need to stop certain medications temporarily. You should also tell your doctor if you have any allergies, especially to contrast dye or local anesthetics. fasting may be required - follow your doctor's specific instructions. Arrange for someone to drive you home after the procedure as movement may be temporarily limited.

What happens during the procedure?

You will lie on a CT scanning table. The procedure typically takes 15-30 minutes. The doctor will use the CT scan to locate the exact nerve(s) to be treated. The skin on your neck will be cleaned and numbed with a local anesthetic. Using the CT images as guidance, a thin needle is carefully inserted toward the target nerve. Once positioned correctly, the medication (typically a combination of local anesthetic and steroid) is injected. You may feel some pressure or mild discomfort during the injection.

What happens after the procedure?

You will be monitored for a short time after the injection. You may experience temporary numbness or weakness in the treated area. Pain relief may be immediate due to the anesthetic, but this typically wears off within a few hours. The steroid component usually begins working within 1-3 days and can provide relief lasting from several days to several months. Follow your doctor's instructions about activity restrictions and when to resume normal activities.

What are the risks?

While generally safe, potential risks include: bleeding or bruising at the injection site; infection; nerve damage (rare); temporary increase in pain; allergic reaction to medications; dizziness or headache; in rare cases, spinal headache or dural puncture. Serious complications are uncommon when performed by an experienced physician.
