BACKGROUND: Sympathetic denervation and impaired angiogenesis cause skin diseases. However, the relationship between the sympathetic nervous system and vascular cell turnover in normal skin remains unclear. OBJECTIVE: To determine the effects of sympathetic denervation on vascular cell turnover in normal skin. METHODS: Rats underwent bilateral L2-4 sympathetic trunk resection (sympathectomy group) or sham operation (control). Hindfoot plantar skin was analyzed 2 weeks and 3 months postoperatively...

The nervous system plays a profound regulatory role in maintaining appropriate immune responses by signaling to immune cells. These immune cells, including B- and T-cells, can further act as intermediary messengers, with subsets of B- and T-cells expressing choline acetyltransferase (ChAT), the enzyme required for acetylcholine (ACh) synthesis. Neural control of ACh release from ChAT+ T-cells can have powerful immune implications, regulating lymphocyte trafficking, inflammation, and prevent death due to experimental septic shock...

BACKGROUND: Vagus nerve stimulation is currently clinically evaluated as a treatment for inflammatory bowel disease. However, the mechanism by which this therapeutic intervention can have an immune-regulatory effect in colitis remains unclear. We determined the effect of intestine-specific vagotomy or intestine-specific sympathectomy of the superior mesenteric nerve (SMN) on dextran sodium sulfate (DSS)-induced colitis in mice. Furthermore, we tested the efficacy of therapeutic SMN stimulation to treat DSS-induced colitis in rats...

BACKGROUND: We present a case series of upper extremity fibromuscular dysplasia (UE FMD) consisting of 22 patients from two tertiary referral centers focusing on clinical presentation, diagnostic findings, and interventional outcomes. FMD is a noninflammatory, nonatherosclerotic arteriopathy that has a predisposition for middle-aged women. Involvement of the UE is thought to be rare. Patients with UE FMD can present with claudication or ischemia, or they can be incidentally diagnosed...

We examined whether glucagon-like peptide-1 (GLP-1) affects β-cell mass and proliferation through neural pathways, from hepatic afferent nerves to pancreatic efferent nerves via the central nervous system, in high-fat diet (HFD)-induced obese rats. The effects of chronic administration of GLP-1 (7-36) and liraglutide, a GLP-1 receptor agonist, on pancreatic morphological alterations, c-fos expression and brain-derived neurotrophic factor (BDNF) content in the hypothalamus, and glucose metabolism were investigated in HFD-induced obese rats that underwent hepatic afferent vagotomy (VgX) and/or pancreatic efferent sympathectomy (SpX)...

All patients (36 hands) with connective tissue disorders who underwent periarterial sympathectomy of the hand alone or in conjunction with vascular bypass at our institution between 1995-2013 were reviewed. The durable resolution of ulcers was significantly higher in patients treated by periarterial sympathectomy and bypass than in patients treated by periarterial sympathectomy alone. Although there were more digital amputations in patients treated by periarterial sympathectomy alone, the difference was not statistically significant...

INTRODUCTION: Facial hyperhidrosis (FH) may lead patients to a significantly impaired quality of life (QOL). Video-assisted thoracoscopic sympathectomy (VATS) is reserved for more severe cases refractory to common first-line agents. The aim of this study was to evaluate the efficacy of VATS for FH and to compare the results between patients with facial hyperhidrosis as main complaint (FHMC) and patients with facial hyperhidrosis as nonmain complaint (FHNMC). METHODS: This was a retrospective study based on medical chart analysis from March 2000 to January 2014: 40 patients with FHMC and 136 patients with FHNMC...

Existing experimental studies of the effect of sympathetic nerve fibers on bone marrow cells are based on the systemic administration of neurotoxic 6-hydroxydopamine. The method of global chemical sympathectomy has some serious disadvantages and could lead to questionable results. We describe a new method of local chemical sympathectomy of rat femoral bone marrow using guanethidine (Ismelin) delivery using an osmotic mini pump. Local guanethidine treatment for 14days led to complete elimination of sympathetic fibers in femoral bone marrow in contrast to bone marrow of contralateral or naïve femurs...

BACKGROUND: Periarterial sympathectomy is a proposed surgical treatment for patients with refractory Raynaud syndrome; however, there is debate regarding the indications and extent of dissection. Due to the segmental arterial sympathetic innervation, we favor an extended sympathectomy in concert with vein graft reconstruction of occluded vessels when necessary. The purpose of this study is to examine outcomes of extended periarterial sympathectomy in our patients. METHODS: A retrospective chart review was performed on 46 patients who underwent 58 periarterial sympathectomies (12 bilateral) since 1981...

The article deals with the literature data on history of and modern attitude to lumbar sympathectomy in treatment for occlusive lesions of lower-limb peripheral arteries. This is followed by analysing the experience of 1,764 operations both independent and those combined with vascular reconstructions over more than a 45-year period. A conclusion is drawn that lumbar sympathectomy remains an operation associated with minimal traumaticity and a low complication rate, thus for long years improving the quality of life and destiny of patients...

BACKGROUND: Endoscopic thoracic sympathectomy (ETS) is indicated for refractory hyperhidrosis. The pulse oximetry-derived perfusion index (PI) quantifies pulsatile blood flow at the oximeter. Thoracic sympathectomy increases blood flow; thus we postulate it will reliably increase PI. We evaluated the ipsilateral finger PI as a predictor of successful sympathectomy during ETS. METHODS: After institutional review board approval and informed consent, 100 adult patients undergoing bilateral ETS were studied...

REVIEW
Fernando Vannucci, José Augusto Araújo
Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches...

Hidehiro Yamamoto, Masayoshi Okada
We describe a new technique of performing sympathectomy with a new device. A single skin incision 3 mm long was made in the armpit. The device enables complete resection of the sympathetic segment through a single skin incision, whereas sympathectomy is limited by the use of the conventional needle technique. Even if sympathetic nerves and blood vessels were overlapping, separation of the two organs was performed safely. This device increases the possibility of planning surgical procedures for patients with difficult anatomies...

BACKGROUND: An otherwise successfully performed endoscopic thoracic sympathectomy (ETS) to treat palmar hyperhidrosis (PH) often has a serious side effect: compensatory sweating (CS). This side effect occurs in other parts of the body to a disturbing extent. The objective of this study is to determine whether there is a relationship between the level of ETS performed on patients with PH, and the occurrence and severity of postoperational CS. METHODS: Between January 2014 and January 2015, ETS procedures were performed on 25 randomly selected consecutive subjects (group A) at T2 level, and on another 25 subjects (group B) at T3 level, who all felt severely handicapped due to PH...

Approximately two decades ago, thoracic surgery witnessed the leap from thoracotomy to the first video-assisted thoracic surgery (VATS) lobectomy. Minimally invasive lobectomy and hilar lymphadenectomy is now widely established as a safe and oncological sound technique that is the standard of care for early-stage lung cancer. The move toward less invasive surgery has no doubt driven the innovation of sophisticated instruments and technology to cope with the demanding need of working through a restricted incision...

BACKGROUND: Palmar hyperhidrosis involves excessive sweating of the palms, with no known etiology. Endoscopic thoracic sympathectomy (ETS) is a safe and effective treatment for palmar hyperhidrosis, but compensatory hyperhidrosis is a common complication after ETS, leading to reduced patient satisfaction and postoperative quality of life. However, the appropriate level of the sympathetic chain to target with ETS to achieve maximum efficacy and reduce the risk of compensatory hyperhidrosis (CH) is controversial...

Conditional expression of diphtheria toxin receptor (DTR) is widely used for tissue-specific ablation of cells. However, diphtheria toxin (DT) crosses the blood-brain barrier, which limits its utility for ablating peripheral cells using Cre drivers that are also expressed in the central nervous system (CNS). Here we report the development of a brain-sparing DT, termed BRAINSPAReDT, for tissue-specific genetic ablation of cells outside the CNS. We prevent blood-brain barrier passage of DT through PEGylation, which polarizes the molecule and increases its size...
