What is a T2-T3 Sympathetic Block?

A T2-T3 sympathetic block is a minimally invasive procedure that targets the sympathetic nerves located at the T2 and T3 vertebral levels of the thoracic spine. This block aims to alleviate chronic pain and treat certain sympathetic nervous system disorders affecting the upper body, including the arms, chest, and upper back.

Indications for T2-T3 Sympathetic Block

Complex Regional Pain Syndrome (CRPS)

A chronic pain condition that often affects the arms.

Refractory Angina

Severe chest pain that does not respond to standard treatments.

Hyperhidrosis

Excessive sweating in the upper body, especially the hands and face.

Raynaud’s Phenomenon

A condition causing some areas of the body, particularly the fingers and toes, to feel numb and cold in response to cold temperatures or stress.

Postherpetic Neuralgia

Persistent pain following an outbreak of shingles (herpes zoster) affecting the upper body.

Procedure

Frame 4

Preparation

The patient is positioned comfortably, typically lying on their back or side, and the skin over the target area is cleaned and numbed with a local anesthetic.
Frame 4

Imaging Guidance

Using fluoroscopy (X-ray guidance) or CT scan, the physician accurately guides a needle to the T2-T3 sympathetic ganglion area.
Frame 4

Injection

A mixture of a local anesthetic and sometimes a corticosteroid is injected to block the nerve signals.
Frame 4

Observation

The patient is monitored for a short time after the injection to assess immediate pain relief and any adverse reactions.
