A number of patients with thoracic outlet syndrome experience intractable pain unresponsive to pharmacologic treatment. In this case, a brachia! plexus neurolysis was performed to address the patient's pain secondary to an enlarging left supraclavicular node. Guided under CT scan, 3 ml of 95% alcohol was injected in between the anterior and middle scalene muscles onto the trunks of the left brachia! plexus, affording immediate pain relief. Particular concerns of motor blockade, phrenic nerve palsy, stellate ganglion blockade, and bleeding did not occur. Therefore, brachia! plexus neurolysis can be safely done at a lower volume, without the above debilitating complications. It can be an option in relieving intractable upper extremity pain.
