Ultrasound-guided pulsed radiofrequency ablation of stellate ganglion in upper-extremity phantom limb pain: a case series.

Background: Phantom limb pain (PLP) is the most common type of pain experienced by amputees and is chronic and complex, with manifestations including pain in a limb that no longer exists. To date, treatments that are pharmaceutical or surgical in nature are relatively ineffective at bringing much relief as the pathophysiology of PLP is somewhat obscure. Chronic pain syndromes such as PLP may benefit from sympathetic nervous system modulation through the stellate ganglion.

Efficacy of stellate ganglion interventions for complex regional pain syndrome in the upper limb-A systematic review and meta-analysis.

Background And Aims: Stellate ganglion (SG) interventions for treating upper limb complex regional pain syndrome (CRPS) have been reported in studies. However, more substantial evidence is required to reach a consensus on its analgesic efficacy. To the best of our knowledge, no systematic review demonstrating the effectiveness of SG intervention for upper limb CRPS has been reported.
