INTRODUCTION: The aim of this study was to assess the frequency of PSMA-HBED uptake in coeliac and stellate ganglia in patients presenting for PSMA-HBED PET/CT scan. METHODS: Prostate-specific membrane antigen-HBED PET/CT scans of 100 consecutive patients were analysed. Coeliac and stellate ganglia were identified by their anatomical location. PSMA-HBED uptake in these ganglia was recorded as either present or absent. If present, the SUVmax value for each ganglion was measured and compared to SUVmax of mediastinal blood pool...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia is an inherited autosomal dominant pathology with an estimated prevalence of 1:2,500 to 1:5,000, being higher in males (3:1). It is characterized histologically by replacement of cardiomyocytes by fibro-adipose tissue, which predisposes to ventricular arrhythmias, right ventricular failure, and sudden cardiac death. The main goal of treatment is to reduce the risk of sudden death and improve the quality of life of patients. We present the case of a 23 year old woman whose clinical symptoms started with palpitations, chest pain with physical activity, syncope and headache 6 years ago during her first pregnancy...

INTRODUCTION: Carbon-ion irradiation of rabbit hearts has improved left ventricular conduction abnormalities through upregulation of gap junctions. However, to date, there has been no investigation on the effect of carbon-ion irradiation on electrophysiological properties in human. We investigated this effect in patients with mediastinum extra-cardiac cancer treated with carbon-ion radiotherapy that included irradiating the heart. METHODS AND RESULTS: In April-December 2009, eight patients were prospectively enrolled (including two male, aged 72...

This study aimed to investigate the effects of estrogen and Cimicifuga racemosa on the stellate ganglion, cardiac norepinephrine pathway, and Ca(2+) /calmodulin-dependent protein kinase II (CaMK II). Forty adult female Sprague Dawley rats were randomly divided into four groups: SHAM, ovariectomized (OVX), ovariectomized with estrogen treatment (E2), and ovariectomized with Cimicifuga racemosa treatment (iCR). After 4 weeks of treatment, norepinephrine (NE) content was determined by high-performance liquid chromatography, and dopamine beta-hydroxylase (DBH) and norepinephrine transporter (NET) expression was detected by immunohistochemistry...

A polyglycolic acid-collagen (PGA-c) tube was used as an artificial nerve guide during facial nerve reconstruction performed in a canine model of stellate ganglion block (SGB). The model was generated using a cervical sympathetic ganglionectomy. We evaluated the effects of blood flow on nerve regeneration. First, we resected the left cervical sympathetic ganglion in beagles (n = 6). We assessed buccal mucosal blood flow and nasal skin temperatures once per week for 12 weeks and Horner's sign 2, 4, and 6 months after resection...

Complex regional pain syndrome (CRPS) is one of the most challenging chronic pain conditions and is characterized by burning pain, allodynia, hyperalgesia, autonomic changes, trophic changes, edema, and functional loss involving mainly the extremities. Until recently, very few reports have been published concerning CRPS involving the orofacial area. We report on a 50-year-old female patient who presented with unbearable pain in all of her teeth and hypersensitivity of the facial skin. She also reported intractable pain in both extremities accompanied by temperature changes and orofacial pain that increased when the other pains were aggravated...

Autonomic modulation is being increasingly employed as a strategy to treat ventricular arrhythmias refractory to beta-blockers, antiarrhythmic drugs and catheter-based ablation procedures. We report 6 patients with refractory ventricular tachycardia (VT) or ventricular fibrillation (VF) treated with stellate ganglion blockade (SGB) and/or bilateral cardiac sympathetic denervation (CSD). Our case series emphasizes the concept that the cardiac sympathetic nerves are important targets in the management of ventricular arrhythmias...

The literature is littered with variable and scant reports of the vertebral nerve. The present paper reviews the literature regarding this nervous structure of the neck and attempts to clarify a number of issues surrounding its form, function, and implications of surgical manipulation. The nerve may arise from the stellate ganglion or the ansa subclavia, amongst a number of other structures. Additionally, the terminal insertion of the vertebral nerve varies in the reported literature, with authors observing various terminations...

Recent reports suggest that ultrasound-guided stellate ganglion block (SGB) is safer and more accurate than classic SGB by the using the surface anatomical landmark. However, previous reports concern the classic paratracheal approach using a small specialized curved probe, which may not be appropriate in some patients. The authors have attempted several approaches, including paratracheal, trans-thyroidal, lateral paracarotid, and lateral approaches, to find a safe and suitable method for real-time ultrasound-guided SGB using a standard high-frequency linear probe...

Heart rate variability (HRV) is increasingly recognized as a means of evaluating autonomic tone. Thoracic epidural anesthesia (TEA) has been previously demonstrated to suppress the electrical storms in patients. However, the effect of TEA on HRV during sympathoexcitation remains unknown. In this study, we aimed to determine the effects of TEA on HRV response to left stellate ganglion stimulation (LSS) in a porcine model. In 12 anesthetized pigs after insertion of an epidural catheter to T1 level, a median sternotomy was performed to expose the heart and the left stellate ganglion...

Aims: Studies have shown that stellate ganglion nerve activity has association with atrial electrical remodelling and atrial fibrillation (AF) inducibility, while median nerve stimulation (MNS) decreases cardiac sympathetic drive. In this study, we tested the hypothesis that MNS suppresses atrial electrical remodelling and AF vulnerability. Methods and results: The atrial effective refractory period (AERP) and AF inducibility at baseline and after 3 h of rapid atrial pacing were determined in dogs undergoing MNS (n = 7), MNS+ application of methyllycaconitine (n = 7) or sham procedure (n = 6)...

Left stellate ganglion (LSG) hyperactivity promotes ischemia induced ventricular arrhythmia (VA). Blocking the Nav1.8 channel decreases neuron activity. Therefore, the present study aimed to investigate whether blocking the Nav1.8 channel with its specific blocker A-803467 in the LSG reduces sympathetic activity and exerts anti-arrhythmic effects. Forty canines were divided into dimethylsulfoxide (DMSO) group and 10 mM, 15 mM, and 20 mM A-803467 groups. A volume of 0.1 ml of A-803467 or DMSO was injected into the LSG...

Studies have shown that brain-derived neurotrophic factor (BDNF) level increase is associated with post-traumatic stress disorder (PTSD) risk. BDNF may be a "missing-link" that mediates the interaction between genetics, environment, and the sympathetic system. Trauma has been shown to induce DNA methylation that in turn can increase BDNF concentration due to increased gene expression. Therapies that focus on the reduction of beta-NGF (BNGF) levels may impact PTSD symptoms. The focus of this paper is to discuss possible effect of stellate ganglion block (SGB) on epigenetic changes noted with PTSD mediated by BDNF and NGF...

BACKGROUND: Imbalances in the autonomic nervous system, namely, excessive sympathoexcitation, contribute to ventricular tachyarrhythmias. While thoracic epidural anesthesia clinically suppresses ventricular tachyarrhythmias, its effects on global and regional ventricular electrophysiology and electrical wave stability have not been fully characterized. The authors hypothesized that thoracic epidural anesthesia attenuates myocardial excitability and the proarrhythmic effects of sympathetic hyperactivity...
