Abstract

Stellate ganglion block is a well established method for the management of certain pain syndromes (e.g., chronic regional pain syndrome, facial pain) in the cervicothoracic region and upper extremity. The stellate ganglion resides between the C7 transverse process and the head of the first rib. Anesthetic injections for the stellate ganglion block are typically made at the level of the transverse process of either the C6 or C7 vertebrae to avoid the pleura, vessels, and nerve roots. Method of positioning the needle tip directly at the ganglion has been described, but are problematic because of the risk of injury to or injection into adjacent structures. It is necessary to know the exact anatomic position of the stellate ganglion when permanent blockade is required by means of radiofrequency thermocoagulation. Whereas fluroscopy shows only bony feature, computerized tomography also images nerves, vessels, and lung, allowing accruate needle placement. We report a case of the percutaneous radiofrequency thermocoagulation of the stellate ganglion after computerized tomography-guided localization.
