Key result
Ultrasound-guided left stellate ganglion block and chemical neurolysis successfully treated refractory ventricular arrhythmia in three patients.
Case Report (n=3)
Ultrasound-guided left stellate ganglion block with chemical neurolysis may serve as an effective rescue or bridge therapy for stabilizing refractory ventricular arrhythmias.
May support rescue use in refractory ventricular arrhythmias; leaves open need for prospective trials.
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.
