Abstract
Arterial thoracic outlet syndrome (aTOS) is a rare, but potentially, limb-threatening condition that is often misdiagnosed. We present the case of a 29-year-old man who was initially managed under the presumption of primary Raynaud's phenomenon for >1 year before the correct diagnosis of aTOS, and the delay in diagnosis was complicated by substantial distal thromboembolic occlusion. Successful staged treatment included thoracic outlet decompression, subclavian artery aneurysm repair with subclavian-to-axillary bypass, anticoagulation, and an unconventional axillary-to-ulnar artery bypass. This report highlights the diagnostic challenges of aTOS and the importance of considering it in patients with Raynaud's phenomenon and vaso-occlusive symptoms.

Abstract
BACKGROUND Thoracic outlet syndrome (TOS) remains a rare diagnosis but is being recognized as a cause of upper extremity dysfunction in professional baseball players. PURPOSE/HYPOTHESIS The purpose was to determine performance and return-to-play (RTP) outcomes in professional baseball players after surgical treatment of TOS. The hypothesis was that there would be a high RTP rate in professional baseball players after TOS surgery with no statistical differences in performance between pitchers who had TOS surgery and matched controls. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All professional baseball players who underwent surgical treatment of TOS between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Demographic and performance data (before and after surgery) for each player were recorded. Performance variables were then compared between players who underwent TOS surgery and matched controls. The matching criteria were no history of previous surgeries on affected arm, age at time of surgery, throwing side, level of play (Major or Minor League Baseball), and years of experience playing professional baseball. RESULTS Overall, 52 players underwent surgery for TOS, of whom 46 (88%) were pitchers. The type of TOS was neurogenic in 69% and venous in 29%. One player had arterial TOS. After TOS surgery, 79% of players returned to play at the same or higher level (RTSP) by 9.5 months and played ≥3 years after surgery. No differences were found in RTSP rate based on the type of TOS. No statistical difference was found in RTP rates between major and minor league players. Pitchers had a 76% RTSP, which was similar to the natural attrition for control pitchers (P = .874). After TOS surgery, pitchers saw a decline in several performance metrics, but these declines were not different from those of control pitchers, indicating that the decline in performance after TOS surgery was no faster than is seen in healthy professional pitchers as they age. CONCLUSION The rate of RTSP after surgery for TOS in professional baseball players was 79%. There was no difference in RTP based on the type of TOS. Pitchers who underwent surgery for TOS had no significant differences in pitching performance metrics after surgery compared with matched controls.

Abstract
Pectoralis minor syndrome (PMS) and quadrilateral space syndrome (QSS) are uncommon neurovascular compression disorders affecting the upper extremity. PMS involves compression under the pectoralis minor muscle, and QSS results from compression in the quadrilateral space-both are classically observed in overhead-motion athletes. Diagnosing PMS and QSS may be challenging due to variable presentations and similarities with other, more common, upper-limb pathologies. Although there is no gold standard diagnostic, local analgesic muscle-block response in a patient with the appropriate clinical context is often all that is required for an accurate diagnosis after excluding more common etiologies. Treatment ranges from conservative physical therapy to decompressive surgery, which is reserved for refractory cases or severe, acute vascular presentations. Decompression generally yields favorable outcomes, with most patients experiencing significant relief and restored baseline function. In conclusion, PMS and QSS, although rare, can cause debilitating upper-extremity symptoms; accurate diagnosis and appropriate treatment offer excellent outcomes, alleviating pain and disability.

Abstract
The physical demands of sports can place patients at elevated risk of use-related pathologies, including thoracic outlet syndrome (TOS). Overhead athletes in particular (eg, baseball and football players, swimmers, divers, and weightlifters) often subject their subclavian vessels and brachial plexuses to repetitive trauma, resulting in venous effort thrombosis, arterial occlusions, brachial plexopathy, and more. This patient population is at higher risk for Paget-Schroetter syndrome, or effort thrombosis, although neurogenic TOS (nTOS) is still the predominant form of the disease among all groups. First-rib resection is almost always recommended for vascular TOS in a young, active population, although a surgical benefit for patients with nTOS is less clear. Practitioners specializing in upper extremity disorders should take care to differentiate TOS from other repetitive use-related disorders, including shoulder orthopedic injuries and nerve entrapments at other areas of the neck and arm, as TOS is usually a diagnosis of exclusion. For nTOS, physical therapy is a cornerstone of diagnosis, along with response to injections. Most patients first undergo some period of nonoperative management with intense physical therapy and training before proceeding with rib resection. It is particularly essential for ensuring that athletes can return to their baselines of flexibility, strength, and stamina in the upper extremity. Botulinum toxin and lidocaine injections in the anterior scalene muscle might predict which patients will likely benefit from first-rib resection. Athletes are usually satisfied with their decisions to undergo first-rib resection, although the risk of rare but potentially career- or life-threatening complications, such as brachial plexus injury or subclavian vessel injury, must be considered. Frequently, they are able to return to the same or a higher level of play after full recovery.

Abstract
INTRODUCTION The presence of a positional compression of the neurovascular bundle in the outlet between the thorax and the upper limb during arm movements (mainly abduction) is common but remains asymptomatic in most adults. Nevertheless, a certain number of subjects with thoracic outlet positional compression will develop incapacitating symptoms or clinical complications as a result of this condition. Symptomatic forms of positional neurovascular bundle compression are referred to as "thoracic outlet syndrome" (TOS). MATERIALS AND METHODS This paper aims to review the literature and discuss the interactions between aspects of patients' lifestyles in TOS. The manuscript will be organized to report (1) the historical importance of lifestyle evolution on TOS; (2) the evaluation of lifestyle in the clinical routine of TOS-suspected patients, with a description of both the methods for lifestyle evaluation in the clinical routine and the role of lifestyle in the occurrence and characteristics of TOS; and (3) the influence of lifestyle on the treatment options of TOS, with a description of both the treatment of TOS through lifestyle changes and the influence of lifestyle on the invasive treatment options of TOS. RESULTS We report that in patients with TOS, lifestyle (1) is closely related to anatomical changes with human evolution; (2) is poorly evaluated by questionnaires and is one of the factors that may induce symptoms; (3) influences the sex ratio in symptomatic athletes and likely explains why so many people with positional compression remain asymptomatic; and (4) can sometimes be modified to improve symptoms and potentially alter the range of interventional treatment options available. CONCLUSIONS Detailed descriptions of the lifestyles of patients with suspected TOS should be carefully analysed and reported.

Abstract
BACKGROUND Thrombotic storm is a series of acute to subacute thrombotic events that evolve over a few days to weeks and result in progressive thromboses at multiple sites. There is often a predisposing event to thromboses, such as trauma or infections. Prompt initiation of anti-coagulation can prove life-saving in such patients. CASE REPORT We describe a previously healthy young male who developed thromboses of the right axillary, brachial, radial, and ulnar arteries while bowling in a cricket match. A few hours later, he developed a stroke involving the right anterior and middle cerebral arteries. His thrombophilia workup was significant for elevated homocysteine levels. Although he had a delayed presentation to our hospital, he was treated with anticoagulation and given a trial of thromboembolectomy, which failed and he had to ultimately undergo a right below-elbow guillotine amputation. CONCLUSION Thrombotic storm should be recognized promptly in the Emergency Department and timely anticoagulation should be initiated.

Abstract
The posterior circumflex humeral artery, a branch of the axillary artery, is compressed by the humeral head during repeated abduction and external rotation of the shoulder joint owing to its anatomical structure. This damages the vascular endothelium, resulting in thrombi, arterial dissection, and aneurysms, a condition known as posterior, circumflex humeral artery pathological lesions. A thrombus may form at the site and becomes a peripheral embolus, resulting in peripheral arterial occlusion.A 21-year-old right-handed elite man college volleyball player noticed coldness and pain in his right hand during a game. Cyanosis was present except in the middle finger, and the beating radial artery was palpable; however, the ulnar artery was not. Doppler ultrasound examination revealed thrombus occlusion of the ulnar artery and common palmar artery of the index finger. Peripheral arterial occlusion was diagnosed due to embolization of a thrombus from this site. The patient stopped practicing volleyball immediately after the onset of symptoms and was started on cilostazol 200 mg and rivaroxaban 15 mg. Subjective coldness of the fingers improved one week after the start of treatment. The patient resumed practice four weeks after the start of treatment and participated in a game by the seventh week.Posterior circumflex humeral artery pathological lesions are caused by overhead motions such as pitching. They are most commonly reported in athletes playing volleyball, although rare, and many cases of aneurysm formation have been reported.Observing a cold sensation in the periphery after practice is necessary for screening.

Abstract
There are approximately 880 and 3,600 major league baseball and minor league baseball players who currently are active in their respective leagues, with thousands of players in the collegiate, high school, and little league ranks. Although relatively uncommon, vascular injuries, such as thoracic outlet syndrome, axillary artery compression, quadrilateral space syndrome, and direct vascular trauma, can afflict these players. These career- and limb-threatening injuries can mimic often seen muscular sprains and strains in their early stages with nonspecific symptoms, such as exertional fatigue, which can delay diagnosis with disastrous sequelae, including thrombus propagation, aneurysm rupture, and ischemia from distal embolization. The goal of this review is to discuss the pathophysiology, diagnosis, and treatment of these injuries to increase awareness of sport-related vascular phenomena among the hand and upper-extremity surgery community because these players typically are seen first in the training room or a hand specialist's office.

Abstract
BACKGROUND Idiopathic upper extremity deep vein thrombosis (UEDVT) management is controversial and ranges from anticoagulation alone to the addition of further interventions such as thrombolysis and decompressive surgery. OBJECTIVES The objective of this systematic review was to assess the effects of anticoagulation alone compared to anticoagulation with additional interventions such as thrombolysis or decompressive surgery on the incidence of recurrent UEDVT and post-thrombotic syndrome (PTS) in patients with idiopathic UEDVT (including those associated with the oral contraceptive pill). PATIENTS/METHODS A systematic search was conducted for studies which focused on acute UEDVT treatment defined as therapies starting within 4 weeks of symptom onset. We limited studies to those that recruited 10 or more subjects and involved at least 6 weeks to 12 months anticoagulation alone or together with additional interventions with at least 6-month follow-up. Primary outcomes were symptomatic recurrent radiologically confirmed UEDVT and PTS. Secondary outcomes were symptomatic venous thromboembolism, bleeding and mortality. RESULTS We found seven studies which reported recurrent UEDVT rates and five that reported PTS rates. All studies were retrospective or cross-sectional. None compared anticoagulation alone to anticoagulation with additional intervention. Study heterogeneity precluded meta-analysis and risk of bias was moderate to serious. Recurrent UEDVT occurred in 0% to 12% post-anticoagulation alone and 0% to 23% post-additional interventions. PTS rates varied from 4% to 32% without severe PTS. Only limited studies reported on our secondary outcomes. CONCLUSION There is limited evidence behind idiopathic UEDVT management. Prospective comparative studies in this area are essential.

Abstract
Thoracic outlet syndrome (TOS) is a rare and heterogeneous syndrome secondary to a compression of the neurovascular bundle in the thoracic outlet area. Muscle hypertrophy is recognized to induce vascular or neurogenic compression, especially in sports involving upper-arm solicitation. Athletes represent a distinctive population because of a specific management due to an ambitious objective, which is returning to high-level competition. We evaluated the scientific literature available for the management of TOS in athletes. Article research extended to March 2021 without other restriction concerning the date of articles publication. The search was performed independently by two assessors. A first preselection based on the article titles was produced, regarding their availability in English or French and a second preselection was produced after reading the abstracts. In case of doubt, a third assessor’s advice was asked. Case reports were selected only if the sport involved was documented, as well as the level of practice. Cohorts were included if data about the number and the sport level of athletes were detailed. Seventy-eight articles were selected including 40 case reports, 10 clinical studies and 28 reviews of literature. Baseball pitchers seem to be highly at risk of developing a TOS. The surgical management appears particularly frequent in this specific population. The prognosis of TOS in athletes seems to be better than in the general population, possibly due to their better physical condition and their younger age. Some studies showed interesting and encouraging results concerning return to previous sport level. Literature shows a strong link between TOS and certain sports. Unfortunately, this syndrome still lacks rigorous diagnostic criteria and management guidelines for athletes.

Abstract
Thoracic outlet syndrome (TOS) is a clinical disorder resulting from compression of the neurovascular bundle of the lower neck and upper chest. TOS can be categorized into neurogenic, venous, and arterial subtypes which result from anatomical compression of the brachial plexus, subclavian vein, and subclavian artery, respectively. This can lead to neurogenic pain as well as vascular injury with thrombosis and thromboembolism. Interventional and diagnostic radiologists play a critical role in the imaging diagnosis and treatment of vascular TOS. Prompt imaging and endovascular management with surgical collaboration has been shown to provide the most successful and long-lasting clinical outcomes, from vessel patency to symptom relief. In this article, we review the anatomy and clinical presentations of TOS as well as the initial imaging modalities used for diagnosis. Furthermore, we detail the role of the diagnostic and interventional radiologist in the management of TOS, including pre-procedure and endovascular interventions, along with medical and surgical treatments. PRECIS: Diagnostic and Interventional Radiologists play a key role in diagnosis and management of vascular thoracic outlet syndromes and are critical for timely and successful outcomes.

Abstract
ABSTRACT Acute upper-limb ischemia is usually secondary to thromboembolic occlusion. The heart is the usual source of emboli in the majority of patients. In a small percentage of cases, the thromboembolic process may start in a proximal large-sized artery, such as the subclavian artery, resulting in thromboembolic occlusion of the upper extremity's small peripheral arteries. In patients with acute upper-limb ischemia, a systematic color flow Doppler ultrasound of the upper extremity arteries may reveal thoracic outlet syndrome as the underlying cause. This pictorial review presents a systemic color flow Doppler approach to evaluate upper extremity arteries in patients with thoracic outlet syndrome presenting as acute ischemia.

Abstract
Thoracic outlet syndrome (TOS) most commonly manifests in overhead athletes (e.g., baseball pitchers, swimmers, weight lifters) due to nerve compression caused by skeletal abnormalities. We present the case of a 43-year-old recreational runner with unilateral upper extremity pain while running. Vascular imaging identified an aberrant subclavian artery origin with positional compression in the absence of cervical bone anomalies confirming arterial TOS. A first rib resection and anterior scalenectomy led to symptom resolution. This case emphasizes the importance of a broad differential and complete workup in non-overhead athletes presenting with symptoms consistent with neurogenic TOS, as vascular interventions may be necessary to prevent future complications.

Abstract
Upper extremity deep vein thrombosis (UEDVT) has been increasing in incidence due to the escalating use of central venous catheters such as peripherally inserted central catheters. UEDVT can be primary idiopathic or secondary to pacemaker leads, intravascular catheters or cancer. In comparison to conventional venous thromboembolism such as lower limb deep vein thrombosis or pulmonary embolism the risk factors, investigations, and management are not well defined. We review current evidence in primary and secondary UEDVT, highlighting areas in need of further research. We also explore the entity of venous thoracic outlet syndrome, which is said to be a risk factor for recurrent primary UEDVT and is the rationale behind surgical interventions.

Abstract
BACKGROUND Anatomically and physiologically, there is strong relationship between the brain and body. A new MRI platform covering both the brain and the limb would be beneficial for a more thorough understanding of the brain-body interactions. NEW METHOD A new arm-over-head (AOH) position was developed to collect MRI of the brain and one arm simultaneously. Subject's tolerability and SNR of both the brain and limb under a serial of seven different TR (250-3000 ms) were tested. Then, blocked motor imagery tasks were performed to test the possible brain-body oscillations. RESULTS The new MRI position provided structural images with good quality, and the AOH position had the best SNR under TR 3000 ms (p = 0.03 for the brain; p = 0.064 for the limb). Then, by using both hypothesis-free independent component analysis (ICA) and a priori seed-based functional connectivity (FC) analysis, it is demonstrated during motionless motor imagery tasks there existed possible brain-body BOLD oscillations connecting especially arm flexors to default mode, vision, and sensorimotor networks. The FC appeared at network density as low as 5%. COMPARISON WITH EXISTING METHODS We have developed a new MRI subject position to explore the possibilities of more extensive neuronal and physiological networks. CONCLUSIONS The results of this preliminary experiment indicate that functional brain networks might extend outside the brain. A bottom-up circulatory effect might explain this phenomenon. Nonetheless, considering the mechanism of neural top-down control and the nature of complex brain networks, the existence of a more extensive whole-body functional network is rational and possible.

Abstract
The subscapularis muscle is the largest muscle of the rotator cuff and its main function is internal rotation. It is morphologically variable in both point of origin and insertion. The presence of an accessory subscapularis muscle can lead to brachial plexus neuropathy. This report presents a very rare accessory subscapularis muscle originating from two distinct bands on the subscapularis and teres major muscles. The insertion was divided among four tendons. The fourth tendon is bifurcated. One of these was connected to the tendon of the subscapularis muscle and the other three inserted into the base of the coracoid process of the scapula. This anomalous muscle has the potential to entrap the nerves of the posterior cord such as the axillary, lower subscapular, and thoracodorsal nerves.

Abstract
PURPOSE OF REVIEW Neurovascular compression in the upper extremity is rare but can affect even those participating in high-level competitive athletics. To assess optimal approaches to treatment, in this review, we evaluate the current literature on neurovascular compressive syndromes affecting the upper extremity, with a special focus on the thoracic outlet syndrome (TOS). RECENT FINDINGS Neurovascular compression at the thoracic outlet can involve the brachial plexus, subclavian artery, or subclavian vein, each with distinct clinical manifestations. Neurogenic TOS is best treated with surgical decompression, if physical therapy has not improved symptoms. Venous TOS results in acute thrombosis superimposed on chronic venous compression. Treatment is best directed at early anticoagulation, catheter-directed thrombolysis, and surgical decompression, with most patients able to discontinue anticoagulation and return to high-level athletic activity. Arterial TOS is related to aneurysmal degeneration of the subclavian artery with distal embolization, leading to limb-threatening ischemia. This should be aggressively treated with surgery. Similar degenerative changes can occur in the axillary artery and its branches, leading to distal embolization. Prompt recognition of these potential sources of limb-threatening ischemia is critical to limb preservation. TOS includes rare but important conditions in the overhead athlete. Recent advances in physical therapy and image-guided diagnostic techniques have facilitated more accurate diagnosis. Surgical treatment remains the gold standard to maximize function or for limb preservation, and future research is needed to clarify optimal pain and physiotherapy regimens, as well as to examine novel approaches to neurovascular decompression.

Abstract
INTRODUCTION The aim of this paper is to provide recommendations for diagnosis and management of arterial or venous aneurysms of the upper extremity. EVIDENCE ACQUISITION A systematic review of the Medline and Cockrane databases was performed from 1988 to 2019 by a combined strategy of MeSh terms. EVIDENCE SYNTHESIS One-hundred-forty-four publications were identified: 111 addressing arterial aneurysms and 33 addressing venous aneurysms. A total of 162 cases of arterial aneurysms, mostly brachial aneurysms (34.0% of cases) and 40 cases of venous aneurysms, mostly located in the forearm (60.0% of cases) were reported. For both types of aneurysms, most common presentation was the perception of a mass (56.3% for arterial one and 87.5% for venous one), but thromboembolic complication (46.7%), paresthesia (16.5%) or rupture (6.4%) could be observed in the setting of arterial aneurysms, while arm swelling (27.5%), neurological symptoms (12.5%), pulmonary embolism (10.0%) or rupture (2.5%) could occur in the setting of venous aneurysms. DUS was performed as first imaging modality for both settings, followed but CTA and MRA, especially in arterial aneurysms, to evaluate distal emboli and surrounding vasculature. Surgical treatment was mostly based on excision of the aneurysms with revascularization for arterial aneurysms (77.2%) and resection without reconstruction for the venous one (85.0%). Complications occurred in 10.5% of the cases of arterial aneurysms, none occurred after venous aneurysm resection. CONCLUSIONS Prompt diagnosis and appropriate preoperative imaging are mandatory in order to offer the best treatment modality. Open resection with revascularization seems to be the treatment of choice for arterial aneurysms, although endovascular procedures became more popular. Venous aneurysms require excision without revascularization.

Abstract
BACKGROUND/OBJECTIVE Sport-related vascular trauma is an important consequence of increased physical activity. Repetitive, high-intensity movements predispose athletes to vascular disease, including arterial pathology, by exerting increased pressure on neurovascular structures. This is an important source of morbidity in an otherwise young and healthy population. Arterial pathology associated with repetitive trauma is often misdiagnosed as musculoskeletal injury. This article increases awareness of sport-related arterial disease by reviewing the symptomatology, investigation, and treatment modalities of this pathology. In addition, prognostic outcomes specific to the athlete are discussed. RESULTS Arterial thoracic outlet syndrome and vascular quadrilateral space syndrome are associated with athletes involved in overhead throwing exercises. Sport-related arterial pathology of the lower limb include external iliac artery endofibrosis (EIAE), popliteal artery entrapment syndrome (PAES), and adductor canal syndrome. Vascular stress and kinking secondary to vessel tethering are important contributors to pathology in EIAE. Chronic exertional compartment syndrome must also be considered, presenting with clinical features similar to PAES. In addition, athletes are predisposed to blunt mechanical trauma. Hypothenar hammer syndrome is one such example, contributing to a high burden of morbidity in this population. CONCLUSIONS In arterial thoracic outlet syndrome and vascular quadrilateral space syndrome, surgery is advocated in symptomatic individuals, with postoperative outcomes favorable for the athlete. Acute limb ischemia may occur as a result of secondary thrombosis or embolization, often without preceding claudication. PAES and adductor canal syndrome are associated with functional entrapment in the athlete, secondary to muscular hypertrophy. Surgical exploration may be indicated. Poorer outcomes are noted when this process is associated with vascular reconstruction. Surgical treatment of EIAE follows failure of conservative management, with limited data available on postoperative prognosis. Investigations for all these conditions should be targeted based on clinical suspicion. A delay in diagnosis can have severe consequences on return to competition in these high-functioning individuals.

Abstract
Thoracic outlet syndrome, a group of diverse disorders, is a collection of symptoms in the shoulder and upper extremity area that results in pain, numbness, and tingling. Identification of thoracic outlet syndrome is complex and a thorough clinical examination in addition to appropriate clinical testing can aide in diagnosis. Practitioners must consider the pathology of thoracic outlet syndrome in their differential diagnosis for shoulder and upper extremity pain symptoms so that patients are directed appropriately to timely therapeutic interventions. Patients with a definitive etiology who have failed conservative management are ideal candidates for surgical correction. This manuscript will discuss thoracic outlet syndrome, occurrence, physical presentation, clinical implications, diagnosis, and management.

Abstract
INTRODUCTION Posterior circumflex humeral artery (PCHA) aneurysm formation and thrombosis as overuse injury in the dominant shoulder can result in ischemia of the forearm, hand and digits due to arterial embolisms. Increased awareness among physicians is necessary as PCHA pathology (PCHAP) might be underdiagnosed. Knowledge of sports and professions at risk and risk-factors for obtaining PCHAP is essential for the development of future preventive measures. This study aims to identify sports and professions at risk as well as risk factors for PCHAP. EVIDENCE ACQUISITION The databases of MEDLINE, EMBASE, BIOSIS, CINAHL and SPORTDiscus were systematically searched. EVIDENCE SYNTHESIS Twenty-seven papers fulfilled the inclusion criteria and described 67 patients with PCHAP involved in seven sports and three professions. The sports (number of cases) were volleyball (41), baseball (13), swimming (1), tennis (3), American football (2), canoeing (1) and yoga (1) (2 unknown). The professions included a baseball coach, a circus trapeze artist and a mechanic. Apart from expert opinions, no studies have identified risk factors for PCHAP. An anatomic variation of the PCHA origin is suggested to be protective for PCHAP. CONCLUSIONS PCHAP is reported in seven overhead sports and three professions. No risk factors for PCHAP were identified. An anatomic variant of the PCHA origin was found to be a potential protective factor for PCHAP. Physicians should be cautious for distal embolization as a result of PCHAP in athletes and workers, both adult and adolescent, involved in repetitive powerful overhead movements.

Abstract
Quadrilateral space syndrome (QSS) is a rare disorder characterized by axillary nerve and posterior humeral circumflex artery (PHCA) compression within the quadrilateral space. Impingement is most frequently due to trauma, fibrous bands, or hypertrophy of one of the muscular borders. Diagnosis can be complicated by the presence of concurrent traumatic injuries, particularly in athletes. Since many other conditions can mimic QSS, it is often a diagnosis of exclusion. Conservative treatment is often first trialed, including physical exercise modification, physical therapy, and therapeutic massage. In patients unrelieved by conservative measures, surgical decompression of the quadrilateral space may be indicated.

Abstract
OBJECTIVES To assess the association between posterior circumflex humeral artery (PCHA) pathology (PCHAP), symptoms and associated risk factors, in elite volleyball players, and to suggest profiles for clinical management and monitoring. DESIGN Cross-sectional study. METHODS A questionnaire assessed symptoms of digital ischemia (DI) in the dominant hand and risk factors among 278 elite indoor and beach volleyball players of whom 6.1% (17/278) was diagnosed with PCHAP using ultrasound. Odds Ratios (OR) including 95% confidence intervals (95%CI) were calculated using binary logistic regression. RESULTS All 278 players completed the questionnaire. Three participants with PCHAP were symptomatic (18%). Ninety-three of 96 symptomatic participants had no PCHAP (OR=0.39; 95% CI 0.13-1.13). Total years playing volleyball (OR 1.14; 95% CI 1.03-1.25) and age (OR 1.17; 95% CI 1.00-1.29) were dose-response related risk factors: a volleyball career of ≥17 years and age of ≥27 years were associated with a 9-fold and 14-fold increased risk of PCHAP, respectively. CONCLUSIONS The volleyball career duration and age are dose-response related risk factors for PCHAP among elite indoor and beach volleyball players. DI symptoms are prevalent in a minority of athletes with PCHAP (3/17; 18%). To enable worldwide standardized care for these athletes at risk, four profiles for clinical management and monitoring have been suggested based on questionnaire and ultrasound outcomes.

Abstract
The diagnosis of thoracic outlet syndrome (TOS) has long been a controversial and challenging one. Despite common presentations with pain in the neck and upper extremity, there are a host of presenting patterns that can vary within and between the subdivisions of neurogenic, venous, and arterial TOS. Furthermore, there is a plethora of differential diagnoses, from peripheral compressive neuropathies, to intrinsic shoulder pathologies, to pathologies at the cervical spine. Depending on the subdivision of TOS suspected, diagnostic investigations are currently of varying importance, necessitating high dependence on good history taking and clinical examination. Investigations may add weight to a diagnosis suspected on clinical grounds and suggest an optimal management strategy, but in this changing field new developments may alter the role that diagnostic investigations play. In this article, we set out to summarise the diagnostic approach in cases of suspected TOS, including the importance of history taking, clinical examination, and the role of investigations at present, and highlight the developments in this field with respect to all subtypes. In the future, we hope that novel diagnostics may be able to stratify patients according to the exact compressive mechanism and thereby suggest more specific treatments and interventions.

Abstract
BACKGROUND Historically, treatment efficacy of professional baseball injuries has been determined by assessing the return-to-play (RTP) rate or using patient-reported functional outcomes scores; however, these methods may not be sensitive and specific enough for elite athletes. As a consequence, performance-based statistics are increasingly being reported in the medical literature. PURPOSE To (1) assess how treatment efficacy is currently reported in professional baseball players; (2) examine the variability in the reporting of these measures in terms of frequency, length of time followed, and units of measure; and (3) identify any attempts to validate these performance-based statistics. STUDY DESIGN Systematic review. METHODS All studies reporting treatment efficacy in professional baseball in PubMed, Embase, and Cochrane were identified. Data collected included frequency and method of reporting: RTP, functional outcomes, and performance-based statistics. RESULTS Fifty-four studies met all inclusion criteria. Of these, 51 (94%) reported RTP, 12 (22%) utilized functional outcomes, and 18 (33%) provided baseball-specific performance-based statistics to assess treatment efficacy. Great variability was seen in how follow-up was defined (games, seasons, months), duration of follow-up, and which performance-based statistics were utilized. None of the studies validated these performance-based statistics, determined minimal time of follow-up needed, or assessed the baseline variability in these statistics among noninjured players. CONCLUSION Most studies reported RTP to determine treatment efficacy, but significant variability was seen in how players were followed. Similarly, great variability was noted in the type and number of performance-based statistics utilized. Additional studies are necessary to validate these measures and determine the appropriate length of time that they should be followed. CLINICAL RELEVANCE This study provides a clear overview of the current methods that are used to determine treatment efficacy in professional baseball players.

Diagnostic properties of the SPIQuestionnaire to detect Posterior Circumflex Humeral Artery Disease in elite volleyball players: a cross-sectional study. Eur J Radiol 2017; 98:20-24. [PMID: 29279163 DOI: 10.1016/j.ejrad.2017.10.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Revised: 09/18/2017] [Accepted: 10/01/2017] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Sports related aneurysmal degeneration and thrombosis of the Posterior Circumflex Humeral Artery (PCHA) has been known to cause symptoms of digital ischemia (DI) in elite volleyball players. Studies have reported symptoms of DI in as much as 28% of the elite indoor volleyball players. The purpose of this study was to determine the diagnostic value of the Shoulder PCHA Pathology and digital Ischemia - Questionnaire (SPI-Q) for detection of sports related PCHA disease using ultrasound data as the standard of reference. METHODS The SPI-Q was completed by elite indoor volleyball players from the highest and single highest Dutch volleyball division and by elite beach volleyball players participating in the 2014 Grand Slam Beach Tournament The Hague (GSBTH). Ultrasound assessment of the dominant shoulder was performed on-site using the SPI-US protocol. The SPI-Q sensitivity, specificity, positive - and negative predictive value and positive - and negative likelihood ratios, and the diagnostic odds ratio were calculated for detection of sports related PCHA disease, using ultrasound as the standard of reference. RESULTS Two hundred twenty-four elite male indoor volleyball players from the Dutch division were included in this study and 62 elite male and female beach volleyball players participating in the GSBTH: a total of 278 players. Thirty-five percent of the players reported symptoms of DI. The prevalence of PCHA disease was 6.1%. For the SPI-Q we found a sensitivity of 18% (95% CI 4-43), specificity of 64% (95% CI 58-70), positive predictive value of 3% (95% CI 0.7-8.9) and negative predictive value of 92% (95% CI 87-96), positive likelihood ratio of 0.50 (95% CI 0.18-1.40), negative likelihood ratio of 1.28 (95% CI 1.01-1.62) and a diagnostic odds ratio of 0.39 (95% CI 0.11-1.38). CONCLUSION The diagnostic value of the SPI-Q to detect PCHA disease in elite volleyball players is poor, which makes it unsuitable as a diagnostic instrument for sports related PCHA disease specifically. However, it can be used to assess all-cause symptoms of DI and raise awareness within athletes and sports physicians, which is important for preventing ischemic complications.

Abstract
Posterior humeral circumflex artery aneurysms in upper extremity athletes are a rarely described entity now beginning to gain wider recognition in the medical literature. Recent studies have demonstrated that these aneurysms may be underdiagnosed and that appropriate recognition with early diagnosis is imperative for improved outcomes. This case report aims to increase awareness of posterior humeral circumflex artery aneurysms and to educate physicians on the appropriate recognition of symptoms, diagnosis, and treatment. We describe two presentations of the same injury, as well as an approach to diagnosis and treatment. We also discuss new diagnostic techniques and future research plans.

Abstract
BACKGROUND Pectoralis minor compression syndrome (PMCS) is a compression of the neurovascular structures in the subpectoral tunnel and remains underestimated in the management of patients with thoracic outlet syndrome (TOS). Its underdiagnosis may be responsible for incomplete or failed treatment. The aim of the study was to evaluate the frequency of PMCS in our experience. METHODS We retrospectively reviewed all patients treated for TOS in our department. We selected those in whom PMCS was diagnosed with a systematic dynamic arteriography. Surgery was performed using the Roos axillary approach when a first rib resection was associated or an elective approach when a first rib resection was not associated. RESULTS From January 2004 to December 2014, 374 surgeries for TOS were performed in 279 patients, which included 90 men (sex ratio = 0.48) with a mean age of 40.1 ± 10 years old. Among these patients, 63 (22.5%) underwent 82 interventions (21.9%) for PMCS, including 26 men (sex ratio = 0.70, P < 0.05) with a mean age of 37.9 ± 9.4 years old. Tenotomy of the pectoralis minor muscle was performed using axillary approach if it was associated with a first rib resection in 74 cases (90.2%) or through an elective approach in 8 cases (9.8%) if it was isolated. Four (4.9%) postoperative complications were found (1 hematoma [1.2%], 1 hemothorax [1.2%], 1 scapula alata [1.2%], and 1 subclavian vein thrombosis [1.2%]), all after an axillary approach. In 63 cases (79.7%), preoperative symptoms were resolved. In 14 cases (17.7%), symptom resolution was incomplete, and 2 patients (2.6%) had recurrent symptoms. CONCLUSIONS Evaluation of PMCS in TOS is justified by its frequency and the simplicity and low morbidity of the surgical procedure.

Abstract
The subscapular, anterior circumflex, and posterior circumflex arteries arise from the third part of the axillary artery. During dissection of the right upper limb of the cadaver of a 70-year-old male, a common trunk was observed arising from the third part of the axillary artery which, after traveling for 0.5 cm, bifurcated into subscapular and posterior circumflex humeral arteries. The common trunk was crossed anteriorly by the radial nerve. The medial nerve was formed by medial and lateral roots on the medial side of the third part of the axillary artery, remaining medial to the brachial artery up to the cubital fossa and then following its usual course thereafter. Awareness of the vascular variations observed in the present case is important when conducting surgical procedures in the axilla, for radiologists interpreting angiographs, and for anatomy-pathologists studying rare findings.

Abstract
OBJECTIVE Arterial thoracic outlet syndrome (TOS) is a rare condition characterized by subclavian artery pathology associated with a bony abnormality. This study assessed contemporary clinical management of arterial TOS at a high-volume referral center. METHODS A prospectively maintained database was used to conduct a retrospective review of patients undergoing primary or reoperative treatment for arterial TOS during an 8-year period (2008 to 2016). Presenting characteristics, operative findings, and clinical and functional outcomes were evaluated. RESULTS Forty patients underwent surgical treatment for arterial TOS, representing 3% of 1401 patients undergoing operations for all forms of TOS during the same interval. Patients were a mean age of 40.3 ± 2.2 years (range, 13-68 years), and 72% were women. More than half presented with upper extremity ischemia/emboli (n = 21) or posterior stroke (n = 2), including eight that had required urgent brachial artery thromboembolectomy. The presentation in 17 (42%) was nonvascular, with 11 having symptoms of neurogenic TOS and six having an asymptomatic neck mass or incidentally discovered subclavian artery dilatation. All patients underwent thoracic outlet decompression (25 supraclavicular, 15 paraclavicular), of which there were 30 (75%) with a cervical rib (24 complete, 6 partial), 5 with a first rib abnormality, 4 with a clavicle fracture, and 1 (reoperation) with no remaining bone abnormality. Subclavian artery reconstruction was performed in 70% (26 bypass grafts, 1 patch, 1 suture repair), and 30% had mild subclavian artery dilatation (<100%) requiring no arterial reconstruction. Mean postoperative length of stay was 5.4 ± 0.6 days. During a mean follow-up of 4.5 ± 0.4 years (range, 0.9-8.1 years), subclavian artery patency was 92%, none had further dilatation or embolism, and chronic symptoms were present in six (4 postischemic/vasospasm, 2 neurogenic). Functional outcomes measured by scores on the 11-item version of the Disability of the Arm, Shoulder and Hand Outcome Measure improved from 39.1 ± 3.8 to 19.2 ± 2.7 (P < .0001). CONCLUSIONS This relatively large single-institution series demonstrates the diverse clinical presentation of arterial TOS coincident with a spectrum of bony and arterial pathology. Current surgical protocols can achieve excellent outcomes for this rare and often complicated condition.

Abstract
The Shoulder posterior circumflex humeral artery Pathology and digital Ischemia - questionnaire (SPI-Q) has been developed to enable periodic surveillance of elite volleyball players, who are at risk for digital ischemia. Prior to implementation, assessing reliability is mandatory. Therefore, the test-retest reliability and agreement of the SPI-Q were evaluated among the population at risk. A questionnaire survey was performed with a 2-week interval among 65 elite male volleyball players assessing symptoms of cold, pale and blue digits in the dominant hand during or after practice or competition using a 4-point Likert scale (never, sometimes, often and always). Kappa (κ) and percentage of agreement (POA) were calculated for individual symptoms, and to distinguish symptomatic and asymptomatic players. For the individual symptoms, κ ranged from "poor" (0.25) to "good" (0.63), and POA ranged from "moderate" (78%) to "good" (97%). To classify symptomatic players, the SPI-Q showed "good" reliability (κ = 0.83; 95%CI 0.69-0.97) and "good" agreement (POA = 92%). The current study has proven the SPI-Q to be reliable for detecting elite male indoor volleyball players with symptoms of digital ischemia.

Abstract
Ischemia of the upper extremity is uncommon but can be seen with open or closed trauma. Those dealing with traumatic injury of the upper extremity should be conversant with techniques of vascular surgery and microsurgery to address these injuries when they occur. Closed injury can occur as well, and at times these are best managed nonoperatively. This article discusses the management of both in the acute setting.

Abstract
Objectives To determine the prevalence of posterior circumflex humeral artery (PCHA) aneurysms and vessel characteristics of the PCHA and deep brachial artery (DBA) in elite volleyball players. Methods Two-hundred and eighty players underwent standardized ultrasound assessment of the dominant arm by a vascular technologist. Assessment included determination of PCHA aneurysms (defined as segmental vessel dilatation ≥150 %), PCHA and DBA anatomy, branching pattern, vessel course and diameter. Results The PCHA and DBA were identified in 100 % and 93 % (260/280) of cases, respectively. The prevalence of PCHA aneurysms was 4.6 % (13/280). All aneurysms were detected in proximal PCHA originating from the axillary artery (AA). The PCHA originated from the AA in 81 % of cases (228/280), and showed a curved course dorsally towards the humeral head in 93 % (211/228). The DBA originated from the AA in 73 % of cases (190/260), and showed a straight course parallel to the AA in 93 % (177/190). Conclusions PCHA aneurysm prevalence in elite volleyball players is high and associated with a specific branching type: a PCHA that originates from the axillary artery. Radiologists should have a high index of suspicion for this vascular overuse injury. For the first time vessel characteristics and reference values are described to facilitate ultrasound assessment. Key Points • Prevalence of PCHA aneurysms is 4.6 % among elite volleyball players. • All aneurysms are in proximal PCHA that originates directly from AA. • Vessel characteristics and reference values are described to facilitate US assessment. • Mean PCHA and DBA diameters can be used as reference values. • Radiologists need a high index of suspicion for this vascular overuse injury.

Abstract
BACKGROUND Because of the tremendous forces produced and the repetitive nature of baseball, players have shown various shoulder adaptations in strength and range of motion. However, no research has identified whether alterations occur in the blood flow to the dominant arm among competitive baseball players. METHODS Twenty professional baseball pitchers and 16 position players participated. Measurements were taken on day 1 of 2 consecutive spring training seasons. Diagnostic ultrasound was used to measure blood flow of the throwing arm brachial artery. These measurements were taken in a standing position with the test arm resting at the participant's side and again with the test arm in a provocative shoulder position. Separate 1-way analyses of variance were conducted to compare blood flow between seasons (P < .05). RESULTS In a resting position, the blood flow of the pitchers did not change from 1 year to the next (P = .48). However, blood flow of the pitchers in the provocative position significantly decreased after the first year (P = .009). The position players did not have any significant changes in blood flow for either arm position (P > .11). CONCLUSIONS In a provocative shoulder position, the blood flow of pitchers significantly decreased after 1 competitive baseball season. These results indicate that after a competitive season, the blood flow to the upper extremity of pitchers may be compromised.

Abstract
Coronary artery aneurysms (CAA) remain an important complication of Kawasaki disease (KD), the most common form of pediatric acquired heart disease in developed countries. Potentially life-threatening CAA develop in 25% of untreated children and 5% of children treated with high-dose intravenous immunoglobulin during the acute phase of the self-limited vasculitis. Noncoronary artery aneurysms (NCAA) in extraparenchymal, muscular arteries occur in a minority of patients with KD who also have CAA, yet little is understood about their formation and remodeling. We postulated that activation of the transforming growth factor-β (TGF-β) pathway in KD may influence formation and remodeling of aneurysms in iliac, femoral, and axillary arteries, the most common sites for NCAA. We studied a resected axillary artery from one adult and endarterectomy tissue from the femoral artery from a second adult, both with a history of CAA and NCAA following KD in infancy. Histology of the axillary artery aneurysm revealed destruction of the internal elastic lamina and recanalization of organized thrombus, while the endarterectomy specimen showed dense calcification and luminal myofibroblastic proliferation. Immunohistochemistry for molecules in the TGF-β signaling pathway revealed increased expression of TGF-β2, TGF-β receptor 2, and phosphorylated SMAD3. These findings suggest ongoing tissue remodeling of the aneurysms decades after the acute injury and demonstrate the importance of the TGF-β signaling pathway in this process.

Abstract
Isolated nonatherosclerotic axillary artery disease is a rare condition. External axillary artery compression can result in occlusion or aneurysm formation and subsequent upper extremity ischemia or distal thromboembolism. Chronic compression from use of crutches and repetitive stretching/compression of the axillary artery secondary to overhead motion during high-performance athletic activities are often implicated as the cause. The uniqueness of these lesions and clinical setting requires a high index of suspicion for axillary artery pathology. Prompt diagnosis with arteriography and surgical treatment is necessary given the propensity for thromboembolism. We present a case highlighting this rare phenomenon in a collegiate baseball pitcher.

Quadrilateral space syndrome: the Mayo Clinic experience with a new classification system and case series. Mayo Clin Proc 2015; 90:382-94.

Abstract
Quadrilateral space syndrome (QSS) arises from compression or mechanical injury to the axillary nerve or the posterior circumflex humeral artery (PCHA) as they pass through the quadrilateral space (QS). Quadrilateral space syndrome is an uncommon cause of paresthesia and an underdiagnosed cause of digital ischemia in overhead athletes. Quadrilateral space syndrome can present with neurogenic symptoms (pain and weakness) secondary to axillary nerve compression. In addition, repeated abduction and external rotation of the arm is felt to lead to injury of the PCHA within the QSS. This often results in PCHA thrombosis and aneurysm formation, with distal emboli. Because of relative infrequency, QSS is rarely diagnosed on evaluation of athletes with such symptoms. We report on 9 patients who presented at Mayo Clinic with QSS. Differential diagnosis, a new classification system, and the management of QSS are discussed, with a comprehensive literature review. The following search terms were used on PubMed: axillary nerve, posterior circumflex humeral artery, quadrilateral space, and quadrangular space. Articles were selected if they described patients with symptoms from axillary nerve entrapment or PCHA thrombosis, or if related screening or imaging methods were assessed. References available within the obtained articles were also pursued. There was no date or language restriction for article inclusion; 5 studies in languages besides English were reported in German, French, Spanish, Turkish, and Chinese.

Abstract
Compression of the neurovascular bundle to the upper extremity can occur above or below the clavicle; thoracic outlet syndrome (TOS) is above the clavicle and pectoralis minor syndrome is below. More than 90% of cases involve the brachial plexus, 5% involve venous obstruction, and 1% are associate with arterial obstruction. The clinical presentation, including symptoms, physical examination, pathology, etiology, and treatment differences among neurogenic, venous, and arterial TOS syndromes. This review details the diagnostic testing required to differentiate among the associated conditions and recommends appropriate medical or surgical treatment for each compression syndrome. The long-term outcomes of patients with TOS and pectoralis minor syndrome also vary and depend on duration of symptoms before initiation of physical therapy and surgical intervention. Overall, it can be expected that >80% of patients with these compression syndromes can experience functional improvement of their upper extremity; higher for arterial and venous TOS than for neurogenic compression.

Abstract
Repetitive, high-stress, or high-impact arm motions can cause upper extremity arterial injuries. The increased functional range of the upper extremity causes increased stresses on the vascular structures. Muscle hypertrophy and fatigue-induced joint translation may incite impingement on critical neurovasculature and can cause vascular damage. A thorough evaluation is essential to establish the diagnosis in a timely fashion as presentation mimics more common musculoskeletal injuries. Conservative treatment includes equipment modification, motion analysis and adjustment, as well as equipment enhancement to limit exposure to blunt trauma or impingement. Surgical options include ligation, primary end-to-end anastomosis for small defects, and grafting.

Abstract
Understanding the utility and interpretation of upper extremity angiography is critical for the hand surgeon treating vaso-occlusive diseases of the hand. Although invasive and requiring the use of contrast dye, it remains the gold standard for imaging of the vascular system of the upper extremity. Angiography may detect numerous variants of the upper limb arterial system which may contribute to surgical pathology. Extensive vascular collateralization helps to maintain perfusion to the hand and facilitates reconstruction of the upper extremity. It is paramount to remember that angiography is a dynamic study and should represent a "flexible roadmap" for surgical reconstruction.

Abstract
CASE We present a case of positional occlusion of the brachial artery after open elbow dislocation and vein graft reconstruction in a pediatric patient. Two years after reconstruction, arterial Doppler studies demonstrated occlusion of the artery; however, an angiogram revealed a widely patent artery. Given the clinical findings of pain and cold intolerance, the patient underwent surgical exploration. Arterial occlusion was found to coincide with elbow flexion. The redundant segment of the basilic vein graft was resected and repaired end-to-end. CONCLUSIONS Vein graft reconstruction of the brachial artery should be checked for patency in flexion prior to closing the incision. Vein grafts with lengths in excess of a defect may kink in flexion due to redundant graft and the relatively thin walls of veins compared to arteries. This case report emphasizes that an understanding of routine tests is invaluable when eliciting the etiology of contradictory test results.

Abstract
PURPOSE OF REVIEW Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. RECENT FINDINGS Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. SUMMARY Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

Decreased blood flow in the throwing arm of professional baseball pitchers. J Shoulder Elbow Surg 2014; 23:1753-1756.

Abstract
BACKGROUND As a consequence of the repetitive forces placed on the throwing arm of a baseball player, various bony, capsuloligamentous, and muscular adaptations occur and have been identified. However, no research has identified whether adaptations also exist in the vasculature of the upper extremity in the competitive baseball player. METHODS Fifty-one professional baseball pitchers and 34 position players participated. Diagnostic ultrasound was used to measure bilateral blood flow of the brachial artery. These measurements were taken with the participant standing with the test arm resting at the participant's side and again with the test arm in a provocative shoulder position. RESULTS The throwing arm of the pitchers had significantly less blood flow volume when in the provocative shoulder position compared with their nonthrowing arm (P = .01). Pitchers did not have any bilateral difference while in the resting position (P = .19). There were no bilateral differences among the position players while in the resting (P = .64) or provocative positions (P = .63). Pitchers had significantly less blood flow of the throwing shoulder while in the provocative position compared with position players (P = .02). There were no other between-group differences. CONCLUSIONS While in a provocative shoulder position, pitchers have significantly less blood flow in their throwing arm compared with their nonthrowing arm and with the throwing arm of position players. These results provide a descriptive profile of blood flow volume among baseball players, which may be used in the evaluation and treatment of such athletes with vascular disorders.
