AI Article Synopsis
- - Sympathetic overactivity is linked to ventricular electrical storm (VES), and stellate ganglion block (SGB) has shown promise in reducing this issue, making it a potential therapy for VES management.
- - A case involving a 60-year-old patient with ventricular tachycardia (VT) led to the placement of an implantable cardioverter defibrillator (ICD) and subsequent use of antitachycardia pacing (ATP) due to ongoing VT episodes.
- - Different SGB techniques were tested, with continuous radiofrequency (CRF) proving more effective than pulsed radiofrequency (PRF) and local anesthesia, resulting in sustained symptom relief for 3 months.
Article Abstract
Sympathetic overactivity is a recognized underlying mechanism contributing to the pathogenesis of ventricular electrical storm (VES). The growing body of evidence supports the efficacy of stellate ganglion block (SGB) in attenuating myocardial sympathetic tone, rendering it a valuable adjunctive therapy for managing VES. This case report presents the clinical details of a 60-year-old patient admitted for ventricular tachycardia (VT), necessitating the implantation of an implantable cardioverter defibrillator (ICD) to mitigate the risk of fatal ventricular arrhythmias (VAs). Subsequently, the patient received repeated antitachycardia pacing (ATP) therapy due to persistent symptomatic VT episodes. SGB was contemplated due to the patient's hemodynamic instability during episodes of VT and the ineffectiveness of pharmacotherapy. Initially, complete suppression of VT was achieved for 3 days using local anesthesia, followed by partial suppression via pulsed radiofrequency (PRF), culminating in sustained relief for 3 months following continuous radiofrequency (CRF) therapy. Different methods of SGB elicited varied responses in this patient. CRF appeared to be more effective than PRF and conventional local anesthetics. CRF ablation of the stellate ganglion for refractory VAs offers a potential therapeutic option.

Background: The best tool for the management of pain associated with distal symmetric peripheral neuropathy (DSPN) is a matter of debate. Therefore, the study aimed to explore whether ultrasound-guided pulsed radiofrequency (PRF) therapy of the stellate ganglion (SG) in type 2 diabetes mellitus (T2DM) patients with painful DSPN could decrease pain severity and the need for analgesics.
Methods: Fifty-six T2DM patients with refractory painful DSPN were enrolled in this study, who then received bilateral ultrasound-guided PRF therapy of SG.

Rosacea is a chronic inflammatory disease primarily affecting the central facial region, significantly involving the facial blood vessels and the sebaceous gland units associated with hair follicles. The stellate ganglion block (SGB) technique can restore balance to autonomic nervous function by interrupting the impulse conduction of preganglionic and postganglionic sympathetic nerve fibers, thereby alleviating excessive peripheral blood vessel contraction, enhancing tissue blood supply, balancing hormone secretion, and modulating immune responses. SGB has demonstrated remarkable efficacy in treating various skin conditions affecting the head, face, and neck.

Complex regional pain syndrome (CRPS) is a chronic debilitating multisystem neuropathic pain disorder. It is characterized by continuous pain, usually out of proportion to any known tissue injury, vasomotor changes, sudomotor or edema, and motor or trophic changes. The objective of this study is to assess the efficacy of neuromodulation, interventional, and unconventional treatments for CRPS.

The occurrence of myocardial infarction (MI)-induced malignant ventricular arrhythmias (VAs) is closely associated with the hyperactivation of left stellate ganglion (LSG). Proinflammatory M1 macrophage is reported to aggravate sympathetic overactivation and cause VAs. Therefore, the depletion of M1 macrophage is anticipated to inhibit LSG overactivation and alleviate MI-induced VAs.
