Clinical Identification of the Vertebral Level at Which the Lumbar Sympathetic Ganglia Aggregate.

CONCLUSIONS: Selection of the primary target in the left lower third of the L4 vertebral body and the right lower margin of the L3 vertebral body may reduce the number of needle insertions and the volume of agents used in conventional or neurolytic LSGB and radiofrequency thermocoagulation.

ConclusionThis is the first ever study reporting the changes in cerebral metabolic activity and multi ‐frame static brain18F FDG PET imaging after L2 DRG stimulation for discogenic low back pain. Predominantly an increased metabolic activity in nociceptive brain matrices are seen with an increased in F18F FDG uptake following L2 DRG stimulation.

Authors: Chen JY, Kubo A, Shinoda M, Okada-Ogawa A, Imamura Y, Iwata K Abstract Although xerostomia can cause persistent oral pain, the mechanisms underlying such pain are not well understood. To evaluate whether a phosphorylated p38 (pp38)-TRPV4 mechanism in trigeminal ganglion (TG) neurons has a role in mechanical hyperalgesia of dry tongue, a rat model of dry tongue was used to study the nocifensive reflex and pp38 and TRPV4 expression in TG neurons. The head-withdrawal reflex threshold for mechanical stimulation of the tongue was significantly lower in dry-tongue rats than in sham rats. The numbers of TRPV4- an...

Assuming one starts at C6 or C7, Seems to me using an out of plane approach makes a lot of sense, for the following reasons: 1. easier to avoid vessels 2. If standing at head, and needle trajectory is from cranial to caudal trajectory, could push meds further caudal to stellate ganglion. thoughts and preferences?

Millions of people with post-traumatic stress disorder (PTSD) — from veterans to rape survivors — have new hope because of a watershed study showing that the injection of an anesthetic to a bundle of nerves in the neck can relieve their symptoms in a clinically significant way. The treatment is known as the stellate ganglion block, or SGB. Used since 1925 for problems such as pain in the arm and shingles, it is safe and effective. In the newly released, eight-week, U.S. Army-funded clinical trial of 108 active-duty service members with PTSD, the nonprofit research institute RTI International found that patients...

Hello: New to this forum. I am a board certified Pain Medicine MD. I have been seeing patients that are interested in stellate ganglion blocks (cervical sympathetic chain) for PTSD, depression, anxiety, etc. Most of these patients found my practice due to the specificity/complexity of this procedure. Apparently, a '60minutes' CBS piece and a Podcast has sparked interest in this procedure for the aforementioned conditions. I have done my due diligence and cannot find literature...

Authors: Chaudhary B, Tripathy PR, Gaikwad MR Abstract Vertebral artery is a branch of 1st part of subclavian artery. Vertebral artery arising from the aortic arch most commonly presents on the left side. The cervical part of sympathetic trunk is closely related to the vertebral artery in the cervical region. Though lots of variations regarding anomalous origin, course of vertebral artery is reported in the literature, here we present a rare anomaly in which vertebral artery after originating from aortic arch is passing through stellate ganglia and it enters into the transverse foramina of higher cervical vertebra ...

This article aims to evaluate the effectiveness, security, and performance difficulty of GIB in patients with pelvic and perineal oncological pain.MethodsA retrospective study between January 2016 and August 2017. Patients with poorly controlled pelvic oncological pain and patients experimenting opioid side effects in which GIB was performed ambulatory were included. Prognostic GIB was performed, under echographic and fluoroscopic control, with local anesthetic and corticoid. The neurolytic block was performed under fluoroscopic guidance. The technique was performed by the same anesthetist with pain management competence. ...

PURPOSE OF REVIEW The goal of this article is to review the anatomy and physiology of pupillary function and then employ that information to develop a comprehensive framework for understanding and diagnosing pupillary disorders. RECENT FINDINGS The contribution of rods and cones to the pupillary light reflex has long been known. A third photosensitive cell type, the intrinsically photosensitive retinal ganglion cell, has recently been discovered. This cell type employs melanopsin to mediate a portion of the pupillary light reflex independent of rods and cones (the postillumination pupillary response) and photic regula...

We report the case of a 65-year-old man brought in by ambulance who complained of chest pain and received an out-of-hospital ECG suggestive of anterior-wall ST-segment elevation myocardial infarction. Shortly after arrival, the patient became unresponsive, with no palpable pulse, and was found to be in ventricular fibrillation. The patient’s ventricular fibrillation persisted despite repeated attempts at standard and double sequential defibrillation, multiple rounds of epinephrine, and amiodarone, magnesium, and bicarbonate. After these interventions were exhausted, a stellate ganglion blockade was conducted after an...
