Stellate ganglion block and neurolysis for refractory ventricular arrhythmia

Abstract

Enhanced electrical activity, ventricular arrhythmia (VA), and cardiac instability due to increased sympathetic tone may be refractory to standard medical treatment and ablation procedures. Stellate ganglion block (SGB) has been used to treat refractory VA; however, there is insufficient information in the literature on its long-term outcome. Herein, we described three patients that were successfully treated with ultrasound-guided left SGB (LSGB) and chemical neurolysis. Ultrasound-guided LSGB may be considered as rescue or bridge therapy for stabilizing ventricular rhythm before a definitive procedure is planned.
