Abstract
Neurological thoracic outlet syndrome (TOS) can be challenging to diagnose, particularly given its described subtypes of neurogenic TOS (NTOS) and disputed TOS (DTOS) that exhibit variable clinical presentations and etiologies. The diagnostic workup of TOS often includes magnetic resonance neurography (MRN) of the brachial plexus. Specific MRN imaging modifications for TOS evaluation are required to maximize spatial and contrast resolution to increase the conspicuity of nerve segments and their relationships to surrounding osseous structures. Dynamic assessment with arm positioning is used to evaluate outlet narrowing and compression of the plexus. Individual nerve segments are interrogated for their longitudinal and cross-sectional morphologies and signal characteristics. In patients with NTOS, MRN may reveal focal impingement of the C8/T1 nerve roots and/or lower trunk with accompanying abnormal T2-weighted signal hyperintensity. Predisposing anatomical entities include cervical ribs, rib synostoses, hypertrophic callous following clavicular fracture, remnant first thoracic rib from prior incomplete resection, and variable perineural scarring. In comparison, DTOS patients frequently demonstrate signal hyperintensity and enlargement of the mid plexus (trunk and division level), with narrowing of the costoclavicular interval. Following comprehensive diagnostic workup that frequently includes electrodiagnostic testing, patients are directed to different management pathways. Nonsurgical management is considered for all cases of DTOS; all patients with NTOS or DTOS who fail conservative treatment warrant referral for a surgical opinion. If surgery is pursued, MRN can be helpful in preoperative planning.

Abstract
Stress fracture of the first rib is a rare but an important cause of brachial plexopathy. Here, we describe a patient with a unilateral brachial plexus injury presenting with involuntary neck movements. A 22-year-old man with cervical involuntary movements for 10 months was diagnosed with tardive dyskinesia. After admission, he abruptly noticed that he could not lift his right arm. The electrophysiological study revealed weakness of the right deltoid and brachioradialis, but normal findings in the other muscles innervated by the right C5 segment. Chest computed tomography showed fractures of the first rib on both sides, with callus formation. Based on the involvement of muscles innervated by the right axillary and radial nerves and presence of callus at the first rib, a diagnosis of right posterior cord entrapment was made. In the present case, intermittent strong contraction of muscles due to dyskinesia may have caused the stress fractures.

Abstract
Botulinum toxin (BTX) injections into the musculature surrounding the brachial plexus have been examined as a potential treatment for neurogenic thoracic outlet syndrome (nTOS). This systematic review identified 15 publications, of which one was a randomized controlled trial. BTX injections performed with ultrasound or electromyographic guidance, and with the inclusion of the pectoralis minor muscle, in addition to the anterior and/or middle scalenes, tended to provide greater symptom improvement and may predict response to first rib resection. Importantly, most studies were of low quality; thus, the results should be interpreted with caution. Further high-quality studies are needed to confirm these findings.

Abstract
Thoracic outlet syndrome (TOS) involves inconsistent symptoms, presenting a challenge for medical providers to diagnose and treat. Thoracic outlet syndrome is defined as a compression injury to the brachial plexus, subclavian artery or vein, or axillary artery or vein occurring between the cervical spine and upper extremity. Three common subcategories are now used for clinical diagnosis: neurogenic, arterial, and venous. Postural position and repetitive motions such as throwing, weightlifting, and manual labor can lead to symptoms. Generally, TOS is considered a diagnosis of exclusion for athletes due to the poor accuracy of clinical testing, including sensitivity and specificity. Thus, determining a definitive diagnosis and reporting injury is difficult. Current literature suggests there is not a gold standard diagnostic test. Rehabilitation has been shown to be a vital component in the recovery process for neurogenic TOS and for arterial TOS and venous TOS in postoperative situations.

Abstract
The diagnosis and clinical features of thoracic outlet syndrome have long confounded clinicians, owing to heterogeneity in symptom presentation and many overlapping competing diagnoses that are "more common." Despite the advent and prevalence of high-resolution imaging, along with the increasing awareness of the syndrome itself, misdiagnoses and untimely diagnoses can result in significant patient morbidity. The authors aimed to summarize the current concepts in the clinical features and diagnosis of thoracic outlet syndrome.

Abstract
Thoracic outlet syndrome (TOS) involves the compression of neurovascular structures in the thoracic outlet. TOS subtypes, including neurogenic (nTOS), venous (vTOS), and arterial (aTOS) are characterized by distinct clinical presentations and diagnostic considerations. This review explores the incidence, diagnostic challenges, and management of TOS with a focus on the innovative approach of Robotic First Rib Resection (R-FRR). Traditional management of TOS includes conservative measures and surgical interventions, with various open surgical approaches carrying risks of complications. R-FRR, a minimally invasive technique, offers advantages such as improved exposure, reduced injury risk to neurovascular structures, and shorter hospital stays. A comprehensive literature review was conducted to assess the outcomes of R-FRR for TOS. Data from 12 selected studies involving 397 patients with nTOS, vTOS, and aTOS were reviewed. The results indicate that R-FRR is associated with favorable intraoperative outcomes including minimal blood loss and low conversion rates to traditional approaches. Postoperatively, patients experienced decreased pain, improved function, and low complication rates. These findings support R-FRR as a safe and effective option for medically refractory TOS.

Abstract
PURPOSE Thoracic outlet syndrome (TOS) is a ductal syndrome that can have a significant functional impact. Various studies have highlighted positional factors and repetitive movements as risk factors for the development of TOS. However, there are few literature data on the socioprofessional consequences of TOS. METHODS We performed a prospective, cross-sectional, descriptive, multicentre study of workers having received a Doppler ultrasound diagnosis of TOS between December 17th, 2018, and March 16th, 2021. Immediately after their diagnosis, patients completed a self-questionnaire on the impact of TOS on their work activities. We assessed the frequency of TOS-related difficulties at work and the associated socioprofessional consequences. Trial Registration Number (TRN) is NCT03780647 and date of registration December 18, 2018. RESULTS Eighty-two participants (95.3%) reported difficulties at work. Seventy-seven of the participants with difficulties (94%) worked in the tertiary sector; these difficulties were due to prolonged maintenance of a posture, carrying loads, and repetitive movements. Although the majority of participants experienced organizational problems and lacked support at work, few of them had approached support organizations, expert and/or healthcare professionals. CONCLUSIONS TOS was almost always associated with difficulties at work (95.3%). However, poor awareness of sources of help or a perceived lack of need may discourage people with TOS from taking steps to resolve these difficulties. It is clear that the socioprofessional management of TOS requires significant improvements.

Abstract
CASE A 74-year-old male patient presenting with chronic radiating shoulder pain, paresthesias, and weakness had previously undergone reverse shoulder arthroplasty and anterior cervical discectomy and fusion for an irreparable cuff tear and cervical radiculopathy, respectively. After being diagnosed with neurogenic thoracic outlet syndrome and undergoing physiotherapy, the patient's recalcitrant condition was surgically managed with arthroscopic pectoralis minor tenotomy, suprascapular nerve release, and brachial plexus neurolysis. CONCLUSION This ultimately led to complete pain relief and improved function. By sharing this case, we aim to shed light on this overlooked pathology and help prevent unnecessary procedures for others suffering from similar conditions.

Abstract
OBJECTIVES Thoracic outlet syndrome (TOS) is a group of disorders caused by impingement of the neurovascular structures at the thoracic outlet. Neurogenic TOS (nTOS), which is thought to be caused by a compression of the brachial plexus, accounts for more than 90% of the cases. Although treatment for nTOS is successful through physiotherapy and/or surgical decompression, little is known about the impact of psychosocial factors, namely, major depressive disorder (MDD), on postoperative outcomes such as non-routine discharge (NRD). Here, we assess whether MDD predicts the type of discharge following nTOS surgical intervention. METHODS A retrospective analysis of the National Inpatient Sample database from the years 2005-2018 was performed. Using the International Classification of Diseases Clinical Modification, Ninth and Tenth revisions, patients who underwent a surgical intervention for nTOS were identified. Our primary outcome was to investigate the effects of MDD on nTOS patient disposition status after surgical management; secondary outcomes included analysis of total hospital charges and length of stay. NRD was defined as anything beyond discharge home without healthcare services. Univariate and multivariable logistic regression analyses were conducted to assess MDD and other potential independent predictors of NRD and prolonged hospital stay (> 2 days) following surgical intervention. RESULTS A total of 6099 patients were identified: 596 (9.77%) patients with MDD and 5503 (90.23%) without MDD. On average, patients with MDD were older (39.6 ± 12.0 years vs. 36.0 ± 13.0 years; p < 0.001), female (80.7% vs. 63.5%; p < 0.001), white (89.6% vs. 85.6%; p = 0.030), and on Medicare (9.6% vs 5.2%; p < 0.001). Univariate and multivariable logistic regression models identified MDD as an independent risk factor associated with a higher risk of NRD (adjusted odds ratio [aOR], 1.50; 95% confidence interval [CI], 1.0-2.2). Additionally, chronic kidney disease (aOR, 2.60; 95% CI, 1.2-5.4), postoperative complications (aOR, 1.87; 95% CI, 1.2-2.9), and Medicare (aOR, 2.95; 95% CI, 1.9-4.7) were statistically significant predictors for higher risk of NRD. However, MDD was not associated with prolonged hospital stay (aOR, 1.00; 95% CI, 0.8-1.2) or higher median of total charges (MDD group: $27,867 vs. non-MDD group: $28,123; p = 0.799). CONCLUSION Comorbid MDD was strongly associated with higher NRD rates following nTOS surgical intervention. MDD had no significant impact on length of hospital stay or total hospital charges. Additional prospective research is necessary in order to better evaluate the impact of MDD in patients with nTOS.

Abstract
We aimed to evaluate functional outcome following elective brachial plexus decompression by compressive fibrous band resection and limited on-demand bone abnormality resection in patients with neurogenic thoracic outlet syndrome (N-TOS). A retrospective continuous observational study was conducted in 17 patients (15 women and 2 men), with a mean age of 42 years, operated on between 2013 and 2021. Twenty brachial plexus decompressions were performed, for 13 objective and 7 subjective N-TOSs, including 3 recurrent N-TOSs. At last follow-up, outcomes were evaluated in terms of residual pain, paresthesia and hand motor deficit, plus patient-reported assessment and Quick-DASH functional scoring. No postoperative complications occurred. At a median follow-up of 12 months (range 6-48 months), complete pain relief and paresthesia resolution were found in 11/15 and 9/14 cases, respectively. All patients reported that their symptoms had improved. In contrast, hand muscle atrophy persisted in all cases (n = 11). Sensorimotor recovery seemed to be poorer and mean Quick-DASH score better in objective than subjective N-TOS patients. Elective brachial plexus decompression seemed to be a safe procedure, providing constant improvement in subjective symptoms related to lower trunk irritation. However, nerve release did not provide hand muscle recovery in patients with objective N-TOS. LEVEL OF EVIDENCE: IV.

Abstract
INTRODUCTION There is a lack of comprehensive and uniform data on primary upper extremity deep venous thrombosis (pUEDVT). pUEDVT includes venous thoracic outlet syndrome related upper extremity deep venous thrombosis (UEDVT) and idiopathic UEDVT. Research on these conditions has been hampered by their rarity, lack of uniform diagnostic criteria, and heterogeneity in therapeutic strategies. To improve current research data collection using input of all various pUEDVT treating medical specialists, we initiated the ThoRacic OuTlet Syndrome (TROTS) registry. The aim of the TROTS registry is to a) collect extensive data on all pUEDVT patients through a predefined protocol, b) give insight in the long term outcome using patient reported outcome measures, c) create guidance in the diagnostic and clinical management of these conditions, and thereby d) help provide content for future research. METHODS AND ANALYSIS The TROTS registry was designed as an international prospective longitudinal observational registry for data collection on pUEDVT patients. All pUEDVT patients, regardless of treatment received, can be included in the registry after informed consent is obtained. All relevant data regarding the initial presentation, diagnostics, treatment, and follow-up will be collected prospectively in an electronic case report form. In addition, a survey containing general questions, a Health-related Quality of Life questionnaire (EQ-5D-5L), and Functional Disability questionnaire (Quick-DASH) will be sent periodically (at the time of inclusion, one and two years after inclusion, and every five years after inclusion) to the participant. The registry protocol was approved by the Medical Ethical Review Board and registered in the Netherlands Trial Register under Trial-ID NL9680. The data generated by the registry will be used for future research on pUEDVT and published in peer reviewed journals. CONCLUSION TROTS registry data will be used to further establish the optimal management of pUEDVT and lay the foundation for future research and guidelines.

Abstract
Context: Thoracic outlet syndrome (TOS) is common among athletes and should be considered as being of arterial origin only if patients have “clinical symptoms due to documented symptomatic ischemia.” We previously reported that upper limb ischemia can be documented with DROPm (minimal value of limb changes minus chest changes) from transcutaneous oximetry (TcpO2) in TOS.Purpose: We aimed to test the hypothesised that forearm (F-) DROPm would better detect symptoms associated with arterial compression during abduction than upper arm (U-) DROPm, and that the thresholds would differ.Methods: We studied 175 patients (retrospective analysis of a cross-sectional acquired database) with simultaneous F-TcpO2 and U-TcpO2 recordings on both upper limbs, and considered tests to be positive (CS+) when upper limb symptoms were associated with ipsilateral arterial compression on either ultrasound or angiography. We determined the threshold and diagnostic performance with a receiver operating characteristic (ROC) curve analysis and calculation of the area under the ROC curve (AUROC) for absolute resting TcpO2 and DROPm values to detect CS+. For all tests, a two-tailed p < 0.05 was considered indicative of statistical significance.Results: In the 350 upper-limbs, while resting U-TcpO2 and resting F-TcpO2 were not predictive of CS + results, the AUROCs were 0.68 ± 0.03 vs. 0.69 ± 0.03 (both p < 0.01), with the thresholds being −7.5 vs. −14.5 mmHg for the detection of CS + results for U-DROPm vs. F-DROPm respectively.Conclusion: In patients with suspected TOS, TcpO2 can be used for detecting upper limb arterial compression and/or symptoms during arm abduction, provided that different thresholds are used for U-DROPm and F-DROPm.Clinical Trial Registration:ClinicalTrials.gov, identifier NCT04376177.

Abstract
Thoracic outlet syndrome (TOS) is a rare condition (1-3 per 100,000) caused by neurovascular compression at the thoracic outlet and presents with arm pain and swelling, arm fatigue, paresthesias, weakness, and discoloration of the hand. TOS can be classified as neurogenic, arterial, or venous based on the compressed structure(s). Patients develop TOS secondary to congenital abnormalities such as cervical ribs or fibrous bands originating from a cervical rib leading to an objectively verifiable form of TOS. However, the diagnosis of TOS is often made in the presence of symptoms with physical examination findings (disputed TOS). TOS is not a diagnosis of exclusion, and there should be evidence for a physical anomaly that can be corrected. In patients with an identifiable narrowing of the thoracic outlet and/or symptoms with a high probability of thoracic outlet neurovascular compression, diagnosis of TOS can be established through history, a physical examination maneuvers, and imaging. Neck trauma or repeated work stress can cause scalene muscle scaring or dislodging of a congenital cervical rib that can compress the brachial plexus. Nonsurgical treatment includes anti-inflammatory medication, weight loss, physical therapy/strengthening exercises, and botulinum toxin injections. The most common surgical treatments include brachial plexus decompression, neurolysis, and scalenotomy with or without first rib resection. Patients undergoing surgical treatment for TOS should be seen postoperatively to begin passive/assisted mobilization of the shoulder. By 8 weeks postoperatively, patients can begin resistance strength training. Surgical treatment complications include injury to the subclavian vessels potentially leading to exsanguination and death, brachial plexus injury, hemothorax, and pneumothorax. In this review, we outline the diagnostic tests and treatment options for TOS to better guide clinicians in recognizing and treating vascular TOS and objectively verifiable forms of neurogenic TOS.

Abstract
BACKGROUND True neurogenic thoracic outlet syndrome (TNTOS) is rare, and evaluation of surgical treatment is limited to a few studies in the literature. The purpose of this study is to present the results from a surgical series of 21 patients with TNTOS. METHODS Retrospective analysis on 21 patients diagnosed with TNTOS who underwent surgery. Demographic data and neurological status were characterized, and patients were classified in accordance with a pre-established scale for assessing the severity of hand impairment before and after surgery. Neuropathic pain was assessed using a visual analogue scale (VAS) and functional disability was quantified using the QuickDASH questionnaire. The results from before and after surgery were compared using the Wilcoxon test, and the significance level was taken to be 5%. RESULTS There was a significant difference in VAS values from before to after the operation (Wilcoxon test: p = 0.0001; r = 0.86). Most patients (90%) improved after surgery, and in 85% of these patients, the VAS improvement was greater than 50%. Improvement in hand function occurred in seven patients (33.3%), and in most of these cases (28.6%), this improvement was classified as mild. Most patients (93.3%) showed moderate to very severe functional disability at the end of the follow-up. CONCLUSION After surgery, only one-third of the cases showed improvement in motor function and most patients had significant functional disability. However, the improvement regarding pain was significant. Surgery to control this symptom should be recommended, even in cases of late presentation and severe motor impairment.

Sleep Problems and Disabilities of the Arm, Shoulder, and Hand in Persons with Thoracic Outlet Syndrome-A Cross-Sectional Study.

Abstract
Thoracic outlet syndrome (TOS) arises as a result of a specific relationship among the anatomical structures that may cause compression in the muscles, nerves, and/or blood vessels in the neck, thereby compromising the local circulation. The aim of the current study was to establish the presence of sleep disturbance and disability in the shoulder, arm, and hand in individuals affected by TOS, as well as to ascertain if there are any differences in these findings relative to TOS-free individuals. The study sample comprised 82 TOS patients and 81 TOS-free individuals aged 19-66 years. Data were gathered by administering the Disabilities of the Arm, Shoulder, and Hand (DASH) and Pittsburgh Sleep Quality Index (PSQI) instruments. The results showed that both the DASH (t = -13.21, p < 0.001) and PSQI (t = -7.27, p < 0.001) scores obtained by the TOS group were higher relative to the controls and were strongly and positively correlated (ρ = 0.58, p < 0.01). As positive DASH scores may be indicative of TOS, they signal the need for further diagnostic evaluations. In individuals in whom TOS is already diagnosed, high DASH scores imply that further sleep quality assessments are required, as compromised sleep patterns may undermine quality of life.

Use of Electroneuromyography in the Diagnosis of Neurogenic Thoracic Outlet Syndrome: A Systematic Review and Meta-Analysis. J Clin Med 2022; 11:jcm11175206.

Abstract
Neurogenic thoracic outlet syndrome (NTOS) is a disabling condition. Its diagnosis remains challenging and is mainly guided by examination. Yet, electrophysiological evaluations are the gold standard for diagnosis of entrapment syndromes. We aimed to assess the interest of electrophysiological evaluation to diagnose NTOS. A systematic literature research was performed using PubMed, ScienceDirect, Embase, Cochrane and Google Scholar databases to collect studies reporting results of electrophysiological assessment of patients with NTOS. Then, a meta-analysis was conducted. Nine studies were eligible and concerned two hundred and thirteen patients. Results were heterogenous among studies and the quality of evidence was very low to moderate. Data could not evaluate sensitivity or specificity of electrophysiological evaluations for NTOS. The meta-analysis found significantly decreased amplitudes of medial antebrachial cutaneous nerve SNAP (sensory nerve action potential), ulnar SNAP, median CMAP (compound motor action potential) and ulnar CMAP. Needle examination found abnormalities for the abductor pollicis brevis, first dorsal interosseous and adductor digiti minimi. Unlike most upper-limb entrapment syndromes, nerve conduction assessment only provided clues in favour of NTOS. Decreased amplitude for ulnar SNAP, medial antebrachial cutaneous SNAP, median CMAP and ulnar CMAP should be assessed, as well as needle examination. Larger studies are needed to evaluate the sensitivity and specificity of electrophysiology in NTOS diagnosis.

Abstract
CONTEXT Thoracic outlet syndrome (TOS) symptoms are prevalent and often confused with other diagnoses. A PubMed search was undertaken to present a comprehensive article addressing the presentation and treatment for TOS. OBJECTIVES This article summarizes what is currently published about TOS, its etiologies, common objective findings, and nonsurgical treatment options. METHODS The PubMed database was conducted for the range of May 2020 to September 2021 utilizing TOS-related Medical Subject Headings (MeSH) terms. A Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) systematic literature review was conducted to identify the most common etiologies, the most objective findings, and the most effective nonsurgical treatment options for TOS. RESULTS The search identified 1,188 articles. The automated merge feature removed duplicate articles. The remaining 1,078 citations were manually reviewed, with articles published prior to 2010 removed (n=771). Of the remaining 307 articles, duplicate citations not removed by automated means were removed manually (n=3). The other exclusion criteria included: non-English language (n=21); no abstracts available (n=56); and case reports of TOS occurring from complications of fractures, medical or surgical procedures, novel surgical approaches, or abnormal anatomy (n=42). Articles over 5 years old pertaining to therapeutic intervention (mostly surgical) were removed (n=18). Articles pertaining specifically to osteopathic manipulative treatment (OMT) were sparse and all were utilized (n=6). A total of 167 articles remained. The authors added a total of 20 articles that fell outside of the search criteria, as they considered them to be historic in nature with regards to TOS (n=8), were related specifically to OMT (n=4), or were considered sentinel articles relating to specific therapeutic interventions (n=8). A total of 187 articles were utilized in the final preparation of this manuscript. A final search was conducted prior to submission for publication to check for updated articles. Symptoms of hemicranial and/or upper-extremity pain and paresthesias should lead a physician to evaluate for musculoskeletal etiologies that may be contributing to the compression of the brachial plexus. The best initial provocative test to screen for TOS is the upper limb tension test (ULTT) because a negative test suggests against brachial plexus compression. A positive ULTT should be followed up with an elevated arm stress test (EAST) to further support the diagnosis. If TOS is suspected, additional diagnostic testing such as ultrasound, electromyography (EMG), or magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) might be utilized to further distinguish the vascular or neurological etiologies of the symptoms. Initial treatment for neurogenic TOS (nTOS) is often conservative. Data are limited, therefore there is no conclusive evidence that any one treatment method or combination is more effective. Surgery in nTOS is considered for refractory cases only. Anticoagulation and surgical decompression remain the treatment of choice for vascular versions of TOS. CONCLUSIONS The most common form of TOS is neurogenic. The most common symptoms are pain and paresthesias of the head, neck, and upper extremities. Diagnosis of nTOS is clinical, and the best screening test is the ULTT. There is no conclusive evidence that any one treatment method is more effective for nTOS, given limitations in the published data. Surgical decompression remains the treatment of choice for vascular forms of TOS.

Abstract
Objective Many publications report outcomes of surgical treatment for neurothoracic outlet syndrome (NTOS); however, high-quality meta-analyses regarding objective evaluation system accessing the long-term outcome of NTOS are lacking. This meta-analysis summarizes and compares the outcomes of Derkosh's classification and vas visual analog scale of the supraclavicular neuroplastic of brachial plexus (SNBP) and trams auxiliary first rib resection (TFRR). Methods The Cochrane Library, PubMed, EMBASE, Allied and Complementary Medicine (AMED) were searched for papers published between January 1980 and February 2021, using the keywords “thoracic outlet syndrome,” “treatment, surgical.” Articles were eligible for inclusion if the following criteria were met studies describing outcomes of surgery for NTOS, published in English, human studies, and available in full text. The exclusion criteria were case reports (n < 10), reviews, abstracts, and studies lacking a control group or without evaluation for two types of surgery. Results We included 10 studies with 1,255 cases, out of which 622 were in the SNBP group; and 633 were in the TFRR group. After surgery (≥12 months), Derkash's classification was improved in 425 cases with SNBP and 364 cases with TFRR. OR = 1.34 (95% CI: 0.94, 1.92), P = 0.03; vas visual analog scale was improved in 282 cases in the SNBP group and 214 cases in the TFRR group. OR = 1.08 (95% CI: 0.63, 1.85), P = 0.78. Conclusion This meta-analysis shows that both SNBP and TFRR are effective for NTOS, but that SNBP is better than TFRR in improving Derkash's classification in the long term. Although patients treated with SNBP are more satisfactory, there is no significant difference in vas visual analog scale from TFRR.

Abstract
BACKGROUND Although numerous articles have been published not only on the classification of thoracic outlet syndrome (TOS) but also on diagnostic standards, timing, and type of surgical intervention, there still remains some controversy because of the lack of level 1 evidence. So far, attempts to generate uniform reporting standards have not yielded conclusive results. OBJECTIVE To systematically review the body of evidence and reach a consensus among neurosurgeons experienced in TOS regarding anatomy, diagnosis, and classification. METHODS A systematic literature search on PubMed/MEDLINE was performed on February 13, 2021, yielding 2853 results. Abstracts were screened and classified. Recommendations were developed in a meeting held online on February 10, 2021, and refined according to the Delphi consensus method. RESULTS Six randomized controlled trials (on surgical, conservative, and injection therapies), 4 "guideline" articles (on imaging and reporting standards), 5 observational studies (on diagnostics, hierarchic designs of physiotherapy vs surgery, and quality of life outcomes), and 6 meta-analyses were identified. The European Association of Neurosurgical Societies' section of peripheral nerve surgery established 18 statements regarding anatomy, diagnosis, and classification of TOS with agreement levels of 98.4 % (±3.0). CONCLUSION Because of the lack of level 1 evidence, consensus statements on anatomy, diagnosis, and classification of TOS from experts of the section of peripheral nerve surgery of the European Association of Neurosurgical Societies were developed with the Delphi method. Further work on reporting standards, prospective data collections, therapy, and long-term outcome is necessary.

Abstract
We investigated the diagnostic utility of combined nerve and vascular ultrasound in thoracic outlet syndrome (TOS) in a retrospective cohort study on two sites, involving 167 consecutive patients with the clinical symptoms suggestive of neurogenic and/or vascular TOS, and an age- and sex-matched control group. All patients and control subjects underwent nerve ultrasound of the supraclavicular brachial plexus to look for fibromuscular anomalies / compression of the brachial plexus in the scalenic region, and vascular ultrasound of the infraclavicular subclavian artery with the arm in neutral and abducted position, serving as an indicator for costoclavicular compression of the neurovascular bundle. Based on clinical symptoms, neurogenic TOS (81%) was the most frequent type of TOS, followed by combined neurogenic and arterial TOS (8%). The frequency of abnormal nerve and/or vascular ultrasound findings differed significantly from the control group (P<0.00001). The pooled sensitivity was 48% for nerve ultrasound, 85% for vascular ultrasound, and 94% when combined. Among the findings, the fibromuscular ‘wedge-sickle sign’, indicating compression of the lower trunk in the scalenic region by a congenital fibromuscular anomaly (e.g. Roos ligaments), showed the highest specificity (100%). A bony ‘wedge-sickle sign’ was also delineated, where lower trunk compression is caused by the neck of the 1st rib. As implied by the higher sensitivity of vascular ultrasound, the most common site of compression was the costoclavicular space, but multilevel compression was also frequently observed. In summary, combined nerve and vascular ultrasound is a sensitive and reliable method to support the diagnosis of TOS. It can also identify the site(s) of compression, with obvious therapeutic consequences.

Abstract
Thoracic outlet syndrome (TOS) is defined as compression of neurovascular components passing the thoracic outlet. While neurologic compression is the most common form, rare cases of arterial comprssion could result in concerning cerebral thromboembolic events. Here we present a 15-year-old female with repeated left hemiparesis and radiologic signs of cerebrovascular accident (CVA) in right middle cerebral artery. Further investigations revealed stenosis of the right subclavian artery, saccular aneurysm, and occlusion of the right brachial artery which suggested the diagnosis of arterial TOS. Based on this report, we present this diagnosis as a rare but important cause of CVA, especially in young patients.

Abstract
BackgroundThoracic outlet syndrome (TOS) is a pathological condition caused by a narrowing between the clavicle and first rib leading to a compression of the neurovascular bundle to the upper extremity. The incidence of TOS is probably nowadays underestimated because the diagnosis could be very challenging without a thorough clinical examination along with appropriate clinical testing. Beside traditional supra-, infraclavicular or transaxillary approaches, the robotic assisted first rib resection has been gaining importance in the last few years.MethodsWe conducted a retrospective cohort analysis of all patients who underwent robotic assisted first rib resection due to TOS at Lucerne Cantonal Hospital and then we performed a narrative review of the English literature using PubMed, Cochrane Database of Systematic Reviews and Scopus.ResultsBetween June 2020 and November 2021, eleven robotic assisted first rib resections were performed due to TOS at Lucerne Cantonal Hospital. Median length of stay was 2 days (Standard Deviation: +/– 0.67 days). Median surgery time was 180 min (Standard Deviation: +/– 36.5). No intra-operative complications were reported.ConclusionsRobotic assisted first rib resection could represent a safe and feasible option in expert hands for the treatment of thoracic outlet syndrome.

Abstract
BACKGROUND: Scalenus syndrome is a collection of symptoms as the consequences of nerve and vascular compression within the scalene triangle. However, the entity has long been forgotten in publications and is difficult to recognize. The diagnosis of scalenus syndrome is mainly based on clinical findings. The Ali Shahab score is a new scoring system, generated based on clinical symptoms of scalenus syndrome.
AIM: In this study, we presented a case series of scalenus syndrome patients who were diagnosed and decide to be managed surgically based on Ali Shahab score. We also reported post-operative outcomes following scalenectomy in our series.
METHODS: This was a case series including patients with scalenus syndrome in Gatot Soebroto Army Hospital, Indonesia, and Siloam Asri Hospital, Indonesia, between 2016 and 2021. The diagnosis of scalenus syndrome was made based on Ali Shahab score with a value of more than 7. All patients were performed scalenectomy to decompress the stenotic subclavian artery and brachial plexus from surrounding fibrotic tissue. Eligible subjects were assessed for sex, side of symptoms, pre-operative and post-operative Ali Shahab score, and post-operative outcome.
RESULTS: We included 96 patients with scalenus syndrome in this case series. Most of the included patients were male (59.4%) and experienced scalenus syndrome on the right side (76%). The average pre-operative Ali Shahab score in our series was 7.12 ± 0.48 and the post-operative score was 0.11 ± 0. Regarding post-operative outcomes, more than half of the patients experienced symptoms reduction with 38.5% of patients experiencing complete resolution of symptoms following scalenectomy.
CONCLUSION: The application of the Ali Shahab score may be used as a diagnostic tool and decision of surgical management for scalenus syndrome patients. Decompression of the subclavian artery and releasing brachial plexus from surrounding fibrotic tissue can improve clinical symptoms in scalenus syndrome patients.

Abstract
INTRODUCTION Chronic compression of the inferior trunk of the brachial plexus can result in severe pain and progressive atrophy and weakness of the musculature of the forearm and hand, known as Gilliatt-Sumner Hand (GSH). The objective of treatment in these patients is to stop further atrophy and pain. Restoration of motor function is thought to be seldom achieved. The aim of this contemporary case series is to describe diagnosis, treatment and outcomes of surgery in GSH. METHODS All patients referred between January 2017 and May 2021 with visible signs of a GSH were included. Visible GSH signs were defined as muscle atrophy of the abductor digiti minimi (ADM), abductor pollicis brevis (APB), and/or interosseous musculature. Additional electrodiagnostic assessment (EDx) and high-resolution ultrasound (HRUS) were performed in all patients. All diagnosed GSH patients underwent thoracic outlet decompression (TOD) surgery by transaxillary (TA) or supraclavicular (SC) approach. Outcomes were measured with the TOS disability scale, Cervical Brachial Score Questionnaire (CBSQ), Disability of the Arm, Shoulder, and Hand (DASH) score and patient reported outcome of motor function, measured with a numerated rating scale score (NRS). The standardized Elevated Arm Stress Test (sEAST) was used to assess motor function before and after TOD. RESULTS Twenty patients were referred to our center with visible signs of a GSH. Clinical examination showed atrophy of the ADM, APB and interosseous musculature in all patients. EDx showed plexopathy of the lower brachial plexus in all patients. HRUS showed an indented inferior trunc of the brachial plexus (so called "wedge sickle sign" WSS) in 18 (90%) patients. Surgical treatment was performed in 17 patients (15 TA-TOD, 2 SC TOD). Three patients refrained from surgical treatment. The median follow-up interval was 15.0 (IQR 14.0) months. The TOS disability scale improved significant (Preoperative: mean 6.31, CI [5.49 - 7.13]; postoperative: mean 4.25, CI [2.80 - 5.70], p=0.026). The same was seen for the CBSQ scores (preoperative mean 77.75, CI [66.63 - 88.87]; postoperative mean 42.65, CI [24.77 - 60.77], p= 0.001) and DASH scores (preoperative mean 59.13, CI [51.49 - 66.77]; postoperative mean 40.96, CI [24.41 - 57.51]; p= 0.032. The NRS for muscle weakness and sEAST showed no statistical difference before and after TOD comparing the whole group (NRS muscle weakness preoperative mean: 6.22, CI [4.31 - 8.14]; postoperative mean: 5.11, CI [3.25 - 6.97]; p= 0.269). However, 4 (23.52%) patients had a 50% or more decrease in NRS for muscle weakness and a minimum increase of 20% in total and average force on the sEAST measurement. The NRS for numbness showed a statistically significant decrease for the whole group (preoperative mean: 5.67, CI [4.18 - 7.16]; postoperative mean: 3.33 [1.37-5.29]; p=0.029). CONCLUSION A combination of physical examination, EDx and HRUS studies can differentiate GSH from differential diagnoses. HRUS appears has the advantage over EDx studies in confirming GSH by visualization of compression of the brachial plexus. TOD surgery will stop the progressive muscle atrophy and significantly reduce NTOS complaints and in some patients, motor function will recover.

Abstract
Objective Thoracic outlet syndrome (TOS) should be considered of arterial origin only if patients have clinical symptoms that are the result of documented symptomatic ischemia. Simultaneous recording of inflow impairment and forearm ischemia in patients with suspected TOS has never been reported to date. We hypothesized that ischemia would occur in cases of severely impaired inflow, resulting in a non-linear relationship between changes in pulse amplitude (PA) and the estimation of ischemia during provocative attitudinal upper limb positioning. Design Prospective single center interventional study. Material Fifty-five patients with suspected thoracic outlet syndrome. Methods We measured the minimal decrease from rest of transcutaneous oximetry pressure (DROPm) as an estimation of oxygen deficit and arterial pulse photo-plethysmography to measure pulse amplitude changes from rest (PA-change) on both arms during the candlestick phase of a “Ca + Pra” maneuver. “Ca + Pra” is a modified Roos test allowing the estimation of maximal PA-change during the “Pra” phase. We compared the DROPm values between deciles of PA-changes with ANOVA. We then analyzed the relationship between mean PA-change and mean DROPm of each decile with linear and second-degree polynomial (non-linear) models. Results are reported as median [25/75 centiles]. Statistical significance was p < 0.05. Results DROPm values ranged −11.5 [−22.9/−7.2] and − 12.3 [−23.3/−7.4] mmHg and PA-change ranged 36.4 [4.6/63.8]% and 38.4 [−2.0/62.1]% in the right and left forearms, respectively. The coefficient of determination between median DROPm and median PA-change was r2 = 0.922 with a second-degree polynomial fitting, but only r2 = 0.847 with a linear approach. Conclusion Oxygen availability was decreased in cases of severe but not moderate attitudinal inflow impairments. Undertaking simultaneous A-PPG and forearm oximetry during the “Ca + Pra” maneuver is an interesting approach for providing objective proof of ischemia in patients with symptoms of TOS suspected of arterial origin.

Abstract
Neurogenic thoracic outlet syndrome (NTOS) represents a disorder believed to involve compression of one or more neurovascular elements as they exit the thoracic outlet. This comprehensive literature review will focus on the occurrence, classification, etiology, clinical presentation, diagnostic measures, and both nonoperative and operative therapies for NTOS. NTOS represents the most common subtype of thoracic outlet syndrome and can significantly impair quality of life. Botulinum toxin injection into the anterior scalene muscle, or even the middle scalene or pectoralis minor muscles, can reduce the symptoms of this syndrome. The best available evidence for botulinum toxin therapy to the cervicothoracic muscles supports the value of this treatment for reducing pain in the affected extremity, and for an approximate duration of 2 months or more. Surgical approaches and newer minimally invasive surgical approaches offer high rates of improvement in select centers.

Abstract
This article discusses the electrodiagnostic assessment of radiculopathy. Relevant anatomy initially is reviewed followed by discussion surrounding the approach to nerve conduction studies and needle electrode examination when it comes to radiculopathy evaluation. Pitfalls of the electrodiagnosis versus clinical diagnosis of radiculopathy and the definitions of acute versus chronic, and active versus inactive, are reviewed.

Abstract
Complaints of the arm, neck and/or shoulder (CANS) are common in the general population (40%) and workers (30%) and have significant economic impact. Twenty-three conditions have been designated as specific CANS. Cases where no cause is identified are reported as non-specific CANS; these cases make up the majority of CANS. Non-specific CANS presentations overlap with clinical entities including cervicobrachial and scalene myofascial syndromes that are associated with neurogenic thoracic outlet syndrome (NTOS). The scalene muscles have been identified as the commonest site of NTOS, although this has been reported to be functional and in conjunction with cervicothoracic junction variants that compromise the brachial plexus lower trunk. Anatomical variants in relation to both the scalene muscles and brachial plexus are not widely recognised in the clinical and imaging literature; however, pass-through and pass-over (or "piercing") variants of the brachial plexus upper trunk and scalene muscles have been well described in the anatomical and anaesthetic literature. In this review, we demonstrate the presence and describe the imaging of scalene muscle pathology and variant muscle-brachial plexus anatomy affecting the upper trunk that are underdiagnosed causes of non-specific CANS presentations and NTOS.

Abstract
Background: Glioblastoma is the most frequent and aggressive malignant brain tumor among adults. Unfortunately, its symptoms can vary considerably depending on the size, location and the anatomic structures of the involved brain. Case report: A 58-year-old male amateur cyclist who suffered from sharp arm pain was examined for a thoracic outlet syndrome due to a previous clavicle fracture. Because of ambiguous results of the neck and nerve plexus imaging, he was referred to a neurosurgeon who properly suspected a brain tumor. The neuroimaging of the brain shown a 3 cm disploriferative mass with a blood enhancement within the left parietal lobe. The mass was urgently removed, and its histologic analysis stated a grade 4 glioblastoma. Conclusion: This case report highlights the differential diagnosis process and the teamwork approach needed to diagnose a rare presentation of a brain glioblastoma, which started its symptoms mimicking a thoracic outlet syndrome caused by a previous bone fracture.

Abstract
ABSTRACT Neurogenic thoracic outlet syndrome (NTOS) is an etiologically and clinically diverse disorder caused by compression of the brachial plexus traversing the thoracic outlet. Athletes who perform repetitive overhead activities are at risk of developing NTOS with sport-specific symptoms. This article reviews the controversial NTOS nomenclature, common sites of anatomic compression, and red flag symptoms that require immediate intervention. It also reviews the congenital, traumatic, and functional etiologies of NTOS, with a discussion of the differential diagnosis, diagnostic criteria, and workup for NTOS. Nonsurgical treatment is highlighted with an emphasis on thoracic outlet syndrome-specific physical therapy and updates on injection options and ultrasound guided hydrodissection. This article compares nonsurgical versus surgical functional outcome data with an emphasis on athletes with NTOS. Functional assessment tools and performance metrics for athletes are reviewed, as well as return to sport considerations.

Abstract
Introduction/Aims Neurogenic thoracic outlet syndrome (NTOS) is a heterogeneous and often disputed entity. An electrodiagnostic pattern of T1 > C8 axon involvement is considered characteristic for the diagnosis of NTOS. However, since the advent of high‐resolution nerve ultrasound (US) imaging, we have encountered several patients with a proven entrapment of the lower brachial plexus who showed a different, variable electrodiagnostic pattern. Methods In this retrospective case series, 14 patients with an NTOS diagnosis with a verified source of compression of the lower brachial plexus and abnormal findings on their electrodiagnostic testing were included. Their medical records were reviewed to obtain clinical, imaging, and electrodiagnostic data. Results Seven patients showed results consistent with the “classic” T1 axon > C8 pattern of involvement. Less typical findings included equally severe involvement of T1 and C8 axons, more severe C8 involvement, pure motor abnormalities, neurogenic changes on needle electromyography in the flexor carpi radialis and biceps brachii muscles, and one patient with an abnormal sensory nerve action potential (SNAP) amplitude for the median sensory response recorded from the third digit. Patients with atypical findings on electrodiagnostic testing underwent nerve imaging more often compared to patients with classic findings (seven of seven patients vs. five of seven respectively), especially nerve ultrasound. Discussion When there is a clinical suspicion of NTOS, an electrodiagnostic finding other than the classic T1 > C8 pattern of involvement does not rule out the diagnosis. High resolution nerve imaging is valuable to diagnose additional patients with this treatable condition. See Editorial on pages 4‐6 in this issue.

Abstract
Thoracic outlet syndrome (TOS) is a group of diverse disorders involving compression of the nerves and/or blood vessels in the thoracic outlet region. TOS results in pain, numbness, paresthesia, and motor weakness in the affected upper limb. We reviewed the pathophysiology, clinical evaluation, differential diagnoses, and treatment of TOS. TOS is usually classified into three types, neurogenic, venous, and arterial, according to the primarily affected structure. Both true neurogenic and disputed TOS are considered neurogenic TOS. Since identifying the causative lesions is complex, detailed history taking and thorough clinical investigation are needed. Electrodiagnostic and imaging studies are helpful for excluding other possible disorders and confirming the diagnosis of true neurogenic TOS. The existence of a disputed TOS remains controversial. Neuromuscular physicians tend to be skeptical about the existence of disputed TOS, but thoracic surgeons argue that disputed TOS is under-diagnosed. Clinicians who encounter patients with TOS need to understand its key features to avoid misdiagnosis and provide appropriate treatment.

Arterial Digital Pulse Photoplethysmography in Patients with Suspected Thoracic Outlet Syndrome: A Study of the "Ca+Pra" Maneuver. Diagnostics (Basel) 2021; 11:diagnostics11061128. [PMID: 34205560 PMCID: PMC8234081 DOI: 10.3390/diagnostics11061128] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Accepted: 06/15/2021] [Indexed: 11/24/2022] Open
Abstract
The level of pulse amplitude (PA) change in arterial digital pulse plethysmography (A-PPG) that should be used to diagnose thoracic outlet syndrome (TOS) is debated. We hypothesized that a modification of the Roos test (by moving the arms forward, mimicking a prayer position (“Pra”)) releasing an eventual compression that occurs in the surrender/candlestick position (“Ca”) would facilitate interpretation of A-PPG results. In 52 subjects, we determined the optimal PA change from rest to predict compression at imaging (ultrasonography +/− angiography) with receiver operating characteristics (ROC). “Pra”-PA was set as 100%, and PA was expressed in normalized amplitude (NA) units. Imaging found arterial compression in 23 upper limbs. The area under ROC was 0.765 ± 0.065 (p < 0.0001), resulting in a 91.4% sensitivity and a 60.9% specificity for an increase of fewer than 3 NA from rest during “Ca”, while results were 17.4% and 98.8%, respectively, for the 75% PA decrease previously proposed in the literature. A-PPG during a “Ca+Pra” test provides demonstrable proof of inflow impairment and increases the sensitivity of A-PPG for the detection of arterial compression as determined by imaging. The absence of an increase in PA during the “Ca” phase of the “Ca+Pra” maneuver should be considered indicative of arterial inflow impairment.

Abstract
Neurogenic thoracic outlet syndrome (N-TOS) is a chronic compressive brachial plexopathy that involves the C8, T1 roots, and/or lower trunk. Medial antebrachial cutaneous (MABC) nerve conduction study (NCS) abnormality is reportedly one of the most sensitive findings among the features of N-TOS. The aim of the present study was to report clinical features, imaging findings, treatment, and prognoses of two N-TOS patients with no abnormalities in electrophysiological studies. Both patients presented with paresthesia of unilateral arm, and examination revealed no neurologic deficits. Electrophysiologic studies including MABC NCS were normal. Computed tomography (CT) angiography and brachial plexus magnetic resonance imaging (MRI) of the patients showed compression and displacement of the neurovascular bundle in the thoracic outlet by causative structures. Due to their sensory symptoms and CT angiography and brachial plexus MRI findings, after excluding other diseases, we diagnosed them with N-TOS. With the development of imaging techniques, more patients presenting with clinical features of lower trunk brachial plexopathy and anomalous structures compressing the neurovascular bundle on imaging studies can be diagnosed with N-TOS, even if electrophysiologic studies including MABC NCS do not show abnormalities.

Abstract
Imaging studies play a significant role in assessment of thoracic outlet syndrome. In this article, we discuss the etiology and definition of thoracic outlet syndrome and review the spectrum of imaging findings seen in patients with thoracic outlet syndrome. We then discuss an optimized technique for computed tomography and MRI of patients with thoracic outlet syndrome, based on the experience at our institution and present some representative examples. Based on our experience, a combination of computed tomography angiography and MRI (with postural maneuvers) effectively demonstrate thoracic outlet syndrome abnormalities.

Abstract
Thoracic outlet syndrome comprises a group of disorders that result in compression of the brachial plexus and subclavian vessels exiting the thoracic outlet. Symptoms include pain, paresthesia, pallor, and weakness depending upon the compromised structures. While consensus in diagnostic criteria has not yet been established, a thorough patient history, physical exam, and appropriate imaging studies are helpful in diagnosis. General first-line therapy for thoracic outlet syndrome is a conservative treatment, and may include physical therapy, lifestyle modifications, NSAIDs, and injection therapy of botulinum toxin A or steroids. Patients who have failed conservative therapy are considered for surgical decompression. This article aims to review the epidemiology, etiology, relevant anatomy, clinical presentations, diagnosis, and management of thoracic outlet syndrome.

Abstract
Thoracic outlet syndrome is a debilitating condition, impairing the function of the upper limb, and can be considered an entrapment of neurovascular structures dedicated to the upper limb. Its open treatment uses a large approach, and to date, only the structures under the clavicle have been endoscopically approached. The purpose of this Technical Note is to describe an endoscopic brachial plexus decompression at all possible entrapment areas between the neck and the arm.

Abstract
BACKGROUND Non-invasive tests are still required to improve the holistic diagnostic approach of thoracic outlet syndrome (TOS). OBJECTIVES We aimed to analyze the diagnostic accuracy of the decrease from rest oxygen pressure (DROP) index of transcutaneous oximetry (TcpO2) in TOS. METHODS Seventy-six patients and 40 asymptomatic volunteers (Controls) were enrolled. In TOS-suspected patients, the arteriograms were investigated for the presence of≥75% stenosis. The area under receiver operating characteristics curve (AUC) analysis tested the ability of forearm TcpO2 during provocative maneuvers to discriminate patients from controls and, to predict a positive arteriographic findings in the 44 TOS-suspected patients that had an arteriography. RESULTS The media [25/75° centile] DROP values of controls and patients were -14 [-8/-22] mmHg and -22 [-12/-42] mmHg, respectively (p for Mann-Whitney<0.02). AUC analysis showed a significant ability of TcpO2 to predict the presence of subclavian arterial compression on arteriography (AUC, 0.694). CONCLUSIONS Although time consuming, tcpO2 is independent of the observer expertise and could be useful in TOS-suspected patients to select the patients that should undergo arteriography.

Abstract
Diseases of the brachial and lumbosacral plexus are uncommon and complex. The diagnosis of plexopathies is often challenging for the clinician, both in terms of localizing a patient's symptoms to the plexus as well as determining the etiology. The non-specific clinical features and similar presentations to other root, nerve, and non-neurologic disorders emphasize the importance of a high clinical index of suspicion for a plexopathy and comprehensive clinical evaluation. Various diagnostic tests, including electrodiagnostic (EDX) studies, neuroimaging (including ultrasound, MRI, or PET), serologic studies, and genetic testing, may be used to confirm a plexopathy and assist in identifying the underlying etiology. EDX testing plays an important role in confirming a plexopathy defining the localization, pathophysiology, chronicity, severity, and prognosis. Given the complexity of the plexus anatomy, multiple common and uncommon NCS and an extensive needle examination is often required, and a comprehensive, individualized approach to each patient is necessary. Treatment of plexopathies often focuses on symptomatic management although, depending on the etiology, specific targeted treatments may improve outcome. This article reviews the clinical features, EDX approaches, and evaluation and treatment of brachial and lumbosacral plexopathies.

Abstract
This study aimed to determine the validity of digital vascular auscultation for the assessment of changes in the radial pulse in healthy subjects, using Doppler sonography as a validated test referent. Sixty-one non-symptomatic subjects (mean age of 52.5 ± 16.1 years) were assigned and evaluated under one of the following conditions: In condition 1, blood flow of the radial artery was not modified; for condition 2, blood flow of the radial artery was modified using a pressure sleeve around the humerus. The radial pulse was then measured three times with each diagnostic tool by three different blinded evaluators. Both instruments demonstrated a high association between the identification of blood flow modifications or not and the assigned condition (p < 0.001). A strong concordance between the two devices when detecting the “changes” or “no changes” in blood flow was demonstrated (k = 0.936, p < 0.001). Stethoscope sensitivity was 95%, and specificity was 99%. In conclusion, digital vascular auscultation seems to be a valid technique to examine blood flow changes of the radial artery in non-symptomatic subjects, and it could be useful for physical therapists when combined with provocative tests for the screening of possible thoracic outlet syndrome in patients.

Abstract
BACKGROUND When conservative therapy for thoracic outlet syndrome fails, scalenectomy with or without first-rib resection (FRR) is the treatment of choice. We measured pressure in the costoclavicular space before and after FRR at time of neurogenic thoracic outlet syndrome release to evaluate whether FRR is required to completely decompress the costoclavicular space. METHODS Using a supraclavicular exposure for anterior-middle scalenectomy with FRR, costoclavicular space pressures were measured using a balloon catheter with the patient's arm in neutral anatomic position, secondarily, the arm abducted and externally rotated. Pressures were recorded in both arm positions before scalenectomy, after scalenectomy, and after FRR. Paired Student's t test was used to compare differences in group means for paired samples. Patient-reported outcomes were reported using the Derkash classification and quick disabilities of the arm, shoulder, and hand (qDASH) questionnaire. RESULTS Fifteen patients (16 cases) surgically treated for neurogenic thoracic outlet syndrome were included in this retrospective study. There was no significant difference in pressure change between arm positions before scalenectomy (161.56 ± 71.65 mm Hg difference) or after scalenectomy (148.5 ± 80.24 mm Hg difference). There was a significant difference in pressure change between post-scalenectomy and post-FRR arm positions; mean pressure change between arm positions after FRR was 50.56 ± 40.28 mm Hg. Mean postoperative qDASH score was 20 ± 23.2. All patients reported improvement in symptoms and functional status. CONCLUSIONS Supraclavicular first rib resection for management of neurogenic thoracic outlet syndrome can be safely performed with favorable outcomes. The pressure increase in the costoclavicular space caused by arm abduction and external rotation was significantly reduced only after FRR, raising concerns about potential incomplete costoclavicular space decompression with scalenectomy alone for neurogenic thoracic outlet syndrome management.

Abstract
The reasons for development of chronic pain are poorly understood. Chronic postoperative pain is linked to severe acute postoperative pain. Head and neck pain is often a complex phenomenon that requires meticulous diagnosis and treatment. Institution of early multimodal analgesic regimens by multidisciplinary teams may attenuate chronic pain formation and propagation in the otolaryngologic patient.

Abstract
OBJECTIVE A clinical, placebo-controlled, randomized, double-blind trial with two parallel groups. OBJECTIVE to evaluate the efficacy of ropivacaine injection in each belly of the anterior and middle scalene muscles, guided by ultrasonography, in the treatment of Nonspecific Thoracic Outlet Syndrome (TOS) compared to cutaneous pressure. METHODS 38 patients, 19 in the control group (skin pressure in each belly of the anterior and middle scalene muscles) and 19 in the intervention group (ropivacaine). Subjects with a diagnosis of Nonspecific Thoracic Outlet Syndrome, pain in upper limbs and/or neck, with no radiculopathy or neurological involvement of the limb affected due to compressive or encephalic root causes were included. The primary endpoint was functionality, evaluated by the Disabilities of the Arm, Shoulder, and Hand - DASH scale validated for use in Brasil. The time of the evaluations were T0 = before the intervention; T1 = immediately after; T2 = 1 week; T3 = 4 weeks; T4 = 12 weeks; for T1, the DASH scale was not applied. RESULTS Concerning the DASH scale, it is possible to affirm with statistical significance (p> 0.05) that the intervention group presented an improvement of functionality at four weeks, which was maintained by the 12th week. CONCLUSION In practical terms, we concluded that a 0.375% injection of ropivacaine at doses of 2.5 ml in each belly of the anterior and middle scalene muscles, guided by ultrasonography, in the treatment of Nonspecific Thoracic Outlet Syndrome helps to improve function.

Abstract
The role of malformed or dilated branches of iliac vessels in causing pelvic pain is not well understood. Such vessels may entrap nerves of the lumbosacral (LS) plexus against the pelvic sidewalls, producing symptoms not typically encountered in gynecological practice, including sciatica and refractory urinary and/or anorectal dysfunction. We describe cases of sciatica in which laparoscopy revealed compression of the LS plexus by variant superior gluteal veins (SGVs). In demonstrating an improvement in patient symptoms after decompression, we identify this neurovascular conflict as a potential intrapelvic cause of sciatica. This study is a retrospective case series (Canadian Task Force Classification II-3). Nerve decompression laparoscopies were performed in São Paulo, Brazil. Thirteen female patients undergoing laparoscopy for sciatica with no clear spinal or musculoskeletal causes were included in this study. In all cases, we identified LS entrapment by aberrant SGVs, and performed decompression by vessel ligation. The average preoperative visual analog scale score of 9.62 ± 0.77 decreased significantly to 2.54 ± 2.88 post-operatively (P < 0.001). The success rate (defined as ≥ 50% improvement in visual analog scale score) was 92.3%, over a follow-up of 13.2 ± 10.6 months. Our case series demonstrates a high success rate and significant decrease in pain scores after laparoscopic intrapelvic decompression, thereby identifying pelvic nerve entrapment by aberrant SGVs as a potential yet previously unrecognized cause of sciatica. This intrapelvic neurovascular conflict—the SGV syndrome—should be considered in cases of sciatica with no identifiable spinal or musculoskeletal etiology.

Microvascular Response to the Roos Test Has Excellent Feasibility and Good Reliability in Patients With Suspected Thoracic Outlet Syndrome. Front Physiol 2019; 10:136. [PMID: 30846945 PMCID: PMC6393400 DOI: 10.3389/fphys.2019.00136] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2018] [Accepted: 02/06/2019] [Indexed: 12/03/2022] Open
Abstract
Background: Exercise oximetry allows operator-independent recordings of microvascular blood flow impairments during exercise and can be used during upper arm provocative maneuvers. Objective: To study the test-retest reliability of upper-limb oximetry during the Roos test in patients with suspected thoracic outlet syndrome (TOS). Materials and Methods: Forty-two patients (28 men, 14 women; mean age: 40.8 years) were examined via transcutaneous oxygen pressure (TcpO2) recordings during two consecutive Roos tests in the standing position. The minimal decrease from rest of oxygen pressure (DROPmin) value was recorded after each maneuver was performed on both arms. The area under the receiver operating characteristic (ROC) curve defined the DROPmin diagnostic performance in the presence of symptoms during the tests. The Mann–Whitney U-test was used to compare the DROPmin in the symptomatic vs. asymptomatic arms. The test-retest reliability was analyzed with Bland-Altman representations. The results are presented as means ± standard deviations (SD) or medians [25–75 percentiles]. Results: The symptoms by history were different from the symptoms expressed during the Roos maneuvers in one-third of the patients. The DROPmin measurements were −19 [−36; −7] mmHg and −8 [−16; −5] mmHg in the symptomatic (n = 108) and asymptomatic (n = 60) arms, respectively. When TOS observed on ultrasound imaging was the endpoint, the area under the ROC curve (AUC) was 0.725 ± 0.058, with an optimal cutoff point of −15 mmHg. This value provided 67% sensitivity and 78% specificity for the presence TOS via ultrasound. When symptoms occurring during the test represented the endpoint, the AUC was 0.698 ± 0.04, with a cutoff point of −10 mmHg. This provided 62% sensitivity and 66% specificity for the presence of pain in the ipsilateral arm during the test. The test-retest reliability of DROPmin proved to be good but not perfect, partly because of unreliability of the provocation maneuvers. Conclusion: To the best of our knowledge, this study is the first to investigate microvascular responses during the Roos maneuver in patients with suspected TOS. The presence of symptoms was significantly associated with ischemia. TcpO2 facilitated the recording of both macrovascular and microvascular responses to the Roos test. The Roos maneuver should probably be performed at least twice in patients with suspected TOS.
