The stellate ganglion is a common target to manage neuropathic pain in the upper extremities. However, the effect duration of a single stellate ganglion block is often temporary. To overcome the short-term effects of a single sympathetic block, pulsed radiofrequency (PRF) can be applied. The aim of the present study was to investigate the efficacy of PRF on the cervical sympathetic chain under ultrasound guidance for complex regional pain syndrome (CRPS).Twelve CRPS patients who underwent PRF on the cervical sympathetic chain were enrolled in this retrospective analysis...

Ga-PSMA-HBED PET/CT showed promising results in staging and restaging of prostate cancer. However, nonspecific uptake has been reported in the celiac ganglia. In this case series, we showed faint radiotracer uptake on upper thoracic region in the location of cervicothoracic (stellate) ganglia. This ganglion is located anterior to the transverse process of C7 vertebra, inferior to subclavian artery, and superior to the neck of the first rib.

Ventricular tachycardia (VT), ventricular fibrillation (VF) and electrical storm are commonly encountered emergency conditions in cardiac and surgical intensive care units. In most cases, recurrent ventricular arrhythmias or electrical storm are associated with a heightened sympathetic tone. These arrhythmias can be difficult to treat and may be refractory to beta-blockade, antiarrhythmic therapy, sedation, and mechanical hemodynamic support. While monomorphic ventricular tachycardia and PVC-triggered polymorphic ventricular tachycardia may sometimes be amenable to successful ablation, some patients may be too critically ill to make such an approach feasible...

This study examined the relationship between neuron density in the stellate ganglion and the severity of basilar artery enlargement after bilateral common carotid artery ligation (BCCAL). Rabbits (n=24) were randomly divided into three groups: an unoperated control group (n=4); an experimental group subjected to BCCAL (n=15); and a sham-operated control group (n=5). A histological examination of the basilar arteries and stellate ganglia was performed 2 months later. Permanent BCCAL was induced by ligation of common carotid arteries at prebifurcation levels as a model for stenoocclusive carotid artery disease...

BACKGROUND: Stellate ganglion blockade (SGB) is mainly used to relieve symptoms of neuropathic pain in conditions such as complex regional pain syndrome and has several potential complications. Noninvasive SGB performed using physical agent modalities (PAMs), such as light irradiation and electrical stimulation, can be clinically used as an alternative to conventional invasive SGB. However, its application protocols vary and its clinical efficacy remains controversial. This study investigated the use of noninvasive SGB for managing neuropathic pain or other disorders associated with sympathetic hyperactivity...

Horner syndrome is rarely observed in connection with epidural anesthesia. It is characterized by ptosis, enophthalmos, miosis, anisocoria, and conjunctival hyperemia in the affected eye, as well as anhydrosis and flushing on the affected side of the face. It is usually a complication spontaneously resolved without permanent neurological deficits. Intraoral anesthesia; stellate ganglion, cervical or brachial plexus blocks; thoracic, lumbar or caudal epidural anesthesia, and intrapleural analgesia are the main causes for Horner syndrome related to anesthesia...

Concerns over the rising prevalence of post-traumatic stress disorder (PTSD), particularly among military service members returning from combat, and over barriers that hinder individuals from seeking out or adhering to standard therapies have contributed to interest in alternative therapies for the disorder. A novel alternative therapy for PTSD-stellate ganglion block (SGB)-may be considered lacking in formal evidence of efficacy despite having shown considerable promise. This review of the recent and historical literature related to SGB finds evidence of substantial beneficial psychiatric effects and substantiates that this fast-acting, somatic treatment may provide positive results for patients with PTSD and may reduce barriers to therapy, particularly among military populations...

BACKGROUND: Renal sympathetic denervation (RD) is a promising method of neuromodulation for the management of cardiac arrhythmia. OBJECTIVE: We tested the hypothesis that RD is antiarrhythmic in ambulatory dogs because it reduces the stellate ganglion nerve activity (SGNA) by remodeling the stellate ganglion (SG) and brain stem. METHODS: We implanted a radiotransmitter to record SGNA and electrocardiogram in 9 ambulatory dogs for 2 weeks, followed by a second surgery for RD and 2 months SGNA recording...

BACKGROUND: Sympathetic nerve activity is important to cardiac arrhythmogenesis. OBJECTIVE: The purpose of this study was to develop a method for simultaneous noninvasive recording of skin sympathetic nerve activity (SKNA) and electrocardiogram (ECG) using conventional ECG electrodes. This method (neuECG) can be used to adequately estimate sympathetic tone. METHODS: We recorded neuECG signals from the skin of 56 human subjects. The signals were low-pass filtered to show the ECG and high-pass filtered to show nerve activity...

OBJECTIVES: In a pilot randomized clinical trial of active stellate ganglion blockade (SGB) versus sham control, SGB significantly reduced the frequency of reported moderate to severe vasomotor symptoms (VMS) and the frequency of physiologic VMS measured using ambulatory skin conductance monitors. Here we examine secondary effects of SGB on verbal learning and memory. STUDY DESIGN: In a randomized, sham-controlled study, 36 women met eligibility criteria for cognitive assessments, of whom 17 were randomized to receive fluoroscopy-guided SGB and 19 to sham control...

This study assessed which symptoms are most impacted following stellate ganglion block (SGB) used to treat post-traumatic stress disorder (PTSD) symptoms. 30 active military service members with combat-related PTSD self-referred to their physician and psychologist. Patients were offered a SGB as part of their treatment program. Primary outcome was the magnitude of change for the 17 items on the PTSD Checklist-Military (PCL-M), which was administered the week before SGB, 1 week after SGB, and 2 to 4 months later...

Mediastinal nerve stimulation (MNS) reproducibly evokes atrial fibrillation (AF) by excessive and heterogeneous activation of intrinsic cardiac (IC) neurons. This study evaluated whether preemptive vagus nerve stimulation (VNS) impacts MNS-induced evoked changes in IC neural network activity to thereby alter susceptibility to AF. IC neuronal activity in the right atrial ganglionated plexus was directly recorded in anesthetized canines (n = 8) using a linear microelectrode array concomitant with right atrial electrical activity in response to: 1) epicardial touch or great vessel occlusion vs...

PURPOSE: Anatomic variations complicate surface landmark-guided needle placement, thereby increasing nerve blockade failure rate. However, little is understood about how anatomic distances change under different clinical conditions. As the cricoid cartilage is an easy and accurate landmark, we investigated changes in distance between the sixth or seventh cervical transverse processes (C6TP or C7TP) and the cricoid cartilage in neutral and extended supine positions. METHODS: Forty-two patients (16 men, 26 women) were included in this study...

Despite the variety of physiological and target-related functions, little is known regarding the cellular complexity in the sympathetic ganglion. We explored the heterogeneity of mouse stellate and thoracic ganglia and found an unexpected variety of cell types. We identified specialized populations of nipple- and pilo-erector muscle neurons. These neurons extended axonal projections and were born among other neurons during embryogenesis, but remained unspecialized until target organogenesis occurred postnatally...

REVIEW
J H Coote, R A Chauhan
Autonomic control of the heart has a significant influence over development of life threatening arrhythmias that can lead to sudden cardiac death. Sympathetic activity is known to be upregulated during these conditions and hence the sympathetic nerves present a target for treatment. However, a better understanding of the anatomy and physiology of cardiac sympathetic nerves is required for the progression of clinical interventions. This review explores the organization of the cardiac sympathetic nerves, from the preganglionic origin to the postganglionic innervations, and provides an overview of literature surrounding anti-arrhythmic therapies including thoracic sympathectomy and dorsal spinal cord stimulation...

AIMS: B-type natriuretic peptide (BNP)-natriuretic peptide receptor A (NPR-A) receptor signalling inhibits cardiac sympathetic neurotransmission, although C-type natriuretic peptide (CNP) is the predominant neuropeptide of the nervous system with expression in the heart and vasculature. We hypothesized that CNP acts similarly to BNP, and that transgenic rats (TGRs) with neuron-specific overexpression of a dominant negative NPR-B receptor would develop heightened sympathetic drive. METHODS AND RESULTS: Mean arterial pressure and heart rate (HR) were significantly (P < 0...
