RESUMO
BACKGROUND: 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 for these patients is to stop further atrophy and pain. Restoration of motor function has been thought to be seldom achieved. The aim of the present contemporary case series was to describe the diagnosis, treatment, and outcomes of surgery for 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, abductor pollicis brevis, and/or interosseous musculature. All the patients had undergone additional electrodiagnostic (ED) assessments and high-resolution ultrasound (HRUS) studies. All the patients with a diagnosis of GSH had undergone thoracic outlet decompression (TOD) surgery using a transaxillary or supraclavicular approach. The outcomes were measured using the thoracic outlet syndrome disability scale, cervical brachial symptom questionnaire, and disability of the arm, shoulder, and hand scale scores and patient-reported outcomes of motor function, measured using a numerical rating scale (NRS). The standardized elevated arm stress test (sEAST) was used to assess the patients' motor function before and after TOD surgery. RESULTS: A total of 20 patients had been referred to our center with visible signs of a GSH. The clinical examination showed atrophy of the abductor digiti minimi, abductor pollicis brevis, and interosseous musculature in all 20 patients. The ED assessments showed plexopathy of the lower brachial plexus in all the patients. HRUS showed an indented inferior trunk of the brachial plexus (so-called wedge-sickle sign) in 18 patients (90%). Of the 20 patients, 17 had undergone TOD surgery (15 transaxillary TOD and 2 supraclavicular TOD). Three patients had refrained from surgery. The median follow-up interval was 15.0 months (interquartile range, 14.0 months). The thoracic outlet syndrome disability scale score had improved significantly (preoperatively: mean, 6.31; 95% confidence interval [CI], 5.49-7.13; postoperatively: mean, 4.25; 95% CI, 2.80-5.70; P = .026). The same improvement was seen for the cervical brachial symptom questionnaire scores (preoperatively: mean, 77.75; 95% CI, 66.63-88.87; postoperatively: mean, 42.65; 95% CI, 24.77-60.77; P = .001) and disability of the arm, shoulder, and hand scale scores (preoperatively: mean, 59.13; 95% CI, 51.49-66.77; postoperatively: mean, 40.96; 95% CI, 24.41-57.51; P = .032). The NRS score for muscle weakness and sEAST score showed no statistically significant differences before and after TOD for the whole group (mean preoperative NRS score for muscle weakness, 6.22; 95% CI, 4.31-8.14; mean postoperative NRS score for muscle weakness, 5.11; 95% CI, 3.25-6.97; P = .269). However, four patients (23.52%) had reported a ≥50% decrease in the NRS score for muscle weakness and a minimum increase of 20% in the total and average force using the sEAST. The NRS for numbness showed a statistically significant decrease for the whole group (preoperatively: mean, 5.67; 95% CI, 4.18-7.16; postoperatively: mean, 3.33; 95% CI, 1.37-5.29; P = .029). CONCLUSIONS: A combination of physical examination, ED assessments, and HRUS studies can differentiate GSH in the differential diagnosis. HRUS appears to have an advantage over ED studies in confirming GSH by visualization of compression of the brachial plexus. TOD surgery will stop the progressive muscle atrophy and significantly reduce neurogenic thoracic outlet syndrome complaints, and, in some patients, motor function will recover.

OBJECTIVES: Surgery for neurogenic thoracic outlet syndrome (NTOS) has shown good outcome in numerous case series. However, 5% to 30% of patients will have persistent or recurrent symptoms, caused by incomplete first rib resection, reattachment of residual scalene muscle, fibrous scarring around the brachial plexus, or a wrong NTOS diagnosis. In patients with a sound diagnosis of recurrent or persisting NTOS, not responding to conservative measures, a secondary procedure can be considered. We report the results of redo thoracic outlet decompression surgery through the supraclavicular approach (SC-REDO-TOD) for persistent or recurrent NTOS. METHODS: A retrospective review of a prospective database was performed. Every patient referred from September 2016 until January 2020 was eligible for inclusion. In an SC-REDO-TOD, we perform complete (cartilage-cartilage) resection of the first rib, any bony and fibrous anomalies, complete anterior and middle scalenectomy, and complete neurolysis of the brachial plexus (complete anatomical decompression of the brachial plexus). Clinical outcomes were assessed by questionnaires including the Disability of Arm, Shoulder and Hand (DASH), Cervico-Brachial Symptoms Questionnaire (CBSQ), and TOS (thoracic outlet syndrome) Disability scale. RESULTS: In total, 45 patients had a SC-REDO-TOD. The median duration of hospital admission after SC-REDO-TOD was 1.41 days (interquartile range, 1.00 day). In total, 30 (66.66%) of 45 patients had recurrent NTOS, and 15 (33.33%) of 45 patients had persisting NTOS. Postoperative complications were seen in eight patients (18.18%). One patient had postoperative complications with permanent impairment (Horner syndrome). Seven patients had postoperative complications with full recovery (three patients had a chylous leakage that was treated with a median-chain triglycerides diet for 6 weeks, three patients had transient phrenic nerve palsy with full recovery <6 weeks, and one patient had a discrete Horner syndrome that resolved in 6 weeks). The median time of follow-up was 19.50 months (interquartile range, 14.00 months) and the response rate to the questionnaires was 91.11% at 6 months and 64.44% at 12 months. We found a positive and statistically significant difference for DASH score, CBSQ score, and TOS Disability Scale score comparing scores for all patients. (DASH score: P < .001; CBSQ score: P < .001; TOS Disability Scale: P < .001). Patients with first rib remnants showed a significant better response (lower DASH, CBSQ and TOS Disability Scale scores) compared with patients without first rib remnants (DASH score: P = .004; CBSQ score: P ≤ .014; TOS Disability Scale: P = .009). CONCLUSIONS: SC-REDO-TOD after a previous NTOS surgery shows good results with a low risk of permanent impairment. Patients with NTOS with first rib remnants after primary surgery seem to benefit the most from SC-REDO-TOD surgery.

OBJECTIVES: The objective of this retrospective analysis of prospectively collected data was to assess the test-retest reliability and validity of the elevated arm stress test (EAST) as measured by the duration in a cohort of patients with suspected neurogenic thoracic outlet syndrome (NTOS). METHODS: Patients evaluated for NTOS between January 2017 and September 2018 were identified. Test-retest reliability by the intraclass correlation coefficient was determined for duration of the EAST. For the validity analysis, patients were classified in a proven NTOS group or a symptomatic control group without NTOS using the Society for Vascular Surgery reporting standards and the outcome of thoracic outlet decompression surgery. A receiver operating characteristic curve was made for the duration of EAST. The area under the curve, and positive and negative predictive values were calculated for the EAST. RESULTS: In total, 428 patients with suspected NTOS were retrospectively analyzed. Of these patients, 61 were excluded because no EAST data was available. Another 101 patients were excluded because of inconclusive reporting standards, arterial or venous TOS, or because thoracic outlet decompression surgery was not performed or had a negative result. The validity analysis in the remaining 266 patients showed an area under the curve for the duration of the EAST of 0.62 (95% confidence interval, 0.55-0.69). The positive predictive value of the duration ranged between 65% and 66%, and the negative predictive value between 53% and 58%. For the test-retest reliability analysis, 118 patients were excluded because they performed only one measurement in a 100-day time period. Analysis in the remaining 148 patients showed an intraclass correlation coefficient value of 0.65 (95% confidence interval, 0.55-0.74) for duration. CONCLUSIONS: The EAST measured by the duration showed a moderate test-retest reliability, but the discriminative value was low in the diagnosis of NTOS. The outcome of the EAST measured by the duration should be used with caution.

OBJECTIVE: We developed a standardized elevated arm stress test (sEAST) meter to standardize patients' posture and measure additional grip and fatigue parameters. In the present prospective cohort study, we aimed to determine the reliability and validity of the sEAST in the diagnosis of neurogenic thoracic outlet syndrome (NTOS). METHODS: Patients evaluated for NTOS between October 2018 and February 2020 were included and performed the sEAST. The patients were classified into a proven NTOS group or a symptomatic control group using the reporting standards for NTOS and the outcome of thoracic outlet decompression surgery. Healthy persons were recruited as an asymptomatic control group. The test-retest reliability, area under the receiver operating characteristic curve, and positive and negative predictive values were calculated for each sEAST parameter. RESULTS: A total of 426 patients with suspected NTOS and 147 healthy controls had performed the sEAST. The validity analysis was performed with data from 111 patients with proven NTOS, 94 symptomatic controls, and 147 asymptomatic controls. The reporting standards were inconclusive for 116 patients; 77 patients had been excluded because thoracic outlet decompression surgery had not been performed or was unsuccessful, and 28 because they had arterial or venous thoracic outlet syndrome. The area under the receiver operating characteristic curve for the proven NTOS group compared with the asymptomatic control and symptomatic control groups ranged from 0.59 to 0.77 and 0.54 to 0.63, respectively. The positive predictive value ranged from 46% to 65% and the negative predictive value from 51% to 66%. The test-retest reliability analysis for 80 patients with multiple sEAST measurements showed moderate to good (0.52-0.87) intraclass correlation coefficient values for the duration and grip strength parameters. However, the grip fatigue parameters demonstrated poor (0.46-0.16) intraclass correlation coefficient values. CONCLUSIONS: The sEAST showed good test-retest reliability for the duration and grip strength parameters. However, the discriminative value of all sEAST parameters was low for NTOS diagnostics. The good test-retest reliability of the sEAST parameters indicates that they could be valuable outcome measures for comparison in a diagnostic care pathway.

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.

OBJECTIVE: Neurogenic thoracic outlet syndrome (NTOS) is one of the most controversial clinical entities in medicine. Several major case series have shown promising results of surgery; however, solid scientific evidence is lacking. The aim of this trial was to objectify the effect of thoracic outlet decompression (TOD). METHODS: A single centre (high volume, tertiary TOS centre), non-blinded, randomised controlled trial was conducted with parallel group design. Patients with a diagnosis of NTOS refractory to conservative therapy were randomised to one of two intervention arms, receiving either a transaxillary thoracic outlet decompression (TA-TOD) or continued conservative treatment. After three months, the conservative treated group was also offered a TA-TOD. The primary outcome was change in Disability of the Arm, Shoulder and Hand (DASH) questionnaire score. Secondary outcomes were changes in Cervical Brachial Symptoms Questionnaire (CBSQ), TOS disability scale, and quality of life scores. Outcomes were assessed at baseline, three, six, and 12 months after inclusion. RESULTS: Fifty patients were enrolled in this trial: 25 in the TA-TOD group and 25 in the continued conservative treatment group. Follow up was completed in 24 and 22 patients, respectively. At three months, there was a statistically significant difference in DASH scores (TA-TOD: mean 45.15, 95% confidence interval [CI] 38.08 - 52.21; conservative treatment: mean 64.92, 95% CI 57.54 - 72.30; p < .001). All patients in the conservative treatment group applied for surgery three months after randomisation. After surgery of the conservative treatment group, there was no statistically significant difference between the groups for all primary and secondary outcome measures. CONCLUSIONS: TA-TOD for NTOS is effective in patients who do not respond to conservative treatment. Trial register number: NL63986.100.17.

BACKGROUND: Duplex ultrasound (DU) is used in the diagnosis of neurogenic thoracic outlet syndrome (NTOS) to measure compression of the subclavian artery (SCA) which is thought to strengthen the NTOS diagnosis. However, the value of DU in NTOS remains unclear. METHODS: A retrospective review of a prospectively acquired database from the TOS center of the Catharina Hospital Eindhoven was performed of patients referred between January 2017 and December 2019. Only "proven NTOS" patients, defined as a successful response to thoracic outlet decompression (TOD) surgery based on patient-reported outcomes (NRS pain scale, CBSQ and DASH score) were included to exclude wrongfully diagnosed NTOS patient. The presence of vascular symptoms (defined as discoloration, edema or temperature changes of the hand or fingers), results of provocative maneuvers, and outcome of DU was used for analysis. To assess the link between vascular symptoms and compression on DU, a chi-squared test was performed. Further, we looked for a correlation between vascular symptoms, compression on DU and clinical outcome using a repeated measures analysis of variance (ANOVA). RESULTS: Vascular symptoms were seen in 49 of 133 patients (36.8%). In total, 51 of 133 patients (38.3%) had at least 50% variation in SCA peak systolic velocity (PSV) during DU at the level of SCA stenosis. SCA occlusion was seen in 11 patients (8.3%) during provocative maneuvers. The presence of clinical "arterial symptoms" was not significantly correlated with vascular laboratory findings, neither for alterations in PSV during DU (P = 0.245) nor for positional SCA occlusion (P = 0.540). No statistically significant correlations between the degree of SCA stenosis and postoperative outcomes, as measured with the DASH, CBSQ, or NRS scale for pain were found (P = 0.787). CONCLUSIONS: The role of DU in the work-up of NTOS in patients with vascular complaints is questionable. Changes in flow velocities are seen in NTOS patients and do not correlate with "vascular symptoms" or clinical outcome.

OBJECTIVE: Peripheral artery disease (PAD) is underdiagnosed in primary care settings, partly because of limited accuracy of the Doppler ankle-brachial index (ABI). This study aimed to assess the diagnostic accuracy of an automated oscillometric ABI device compared with reference standard vascular laboratory Doppler ABI equipment and to examine the influence of oscillometric errors on performance. METHODS: Consecutive patients who were referred to a large general hospital for an ABI measurement were invited to participate. In each patient, the oscillometric analysis was followed by the Doppler analysis. Legs with incompressible ankle arteries were excluded from analysis. ABI values were compared using the Bland-Altman method. Oscillometric errors were defined as the incapacity of the oscillometer to report a value of ABI. A receiver operating characteristic curve was constructed, and the area under the curve was computed. RESULTS: A total of 201 patients participated. The Bland-Altman plot showed a mean difference of 0.05 ± 0.12 (limits of agreement, -0.20 to 0.29), representing a small ABI overestimation after oscillometry. Oscillometric errors occurred more commonly in limbs with PAD than in limbs without PAD (28% and 7%, respectively; P < .001). Considering a 0.9 threshold and after oscillometric error exclusion, the oscillometric ABI showed a 74% sensitivity and a 97% specificity for a diagnosis of PAD. When oscillometric errors were considered as abnormal ABIs, sensitivity increased to 86% and specificity was maintained at 95%. The receiver operating characteristic curve showed an area under the curve of 0.96. The best oscillometric ABI cutoff point was 1.00. Using this threshold and when considering oscillometric errors as abnormal ABIs, sensitivity improved to 94% while maintaining specificity at 92%. CONCLUSIONS: Oscillometric ABI showed good diagnostic accuracy compared with the reference standard. However, the high incidence of oscillometric errors and the challenges to correctly interpret readings may limit the use of the oscillometric method in PAD diagnosis.

OBJECTIVE: The North American Society for Vascular Surgery (SVS) reporting standards for neurogenic thoracic outlet syndrome (NTOS) were published in 2016 to produce consistency in the diagnosis and treatment of NTOS, but outcomes resulting from following these standards are not yet available. The results of a standardised multidisciplinary care pathway for NTOS based on the North American SVS reporting standards for NTOS are reported. METHODS: Patients referred between August 2016 and December 2019 with suspected NTOS were evaluated in this single center prospective cohort study. Diagnosis and treatment were performed according to a care pathway based on the North American SVS reporting standards. The outcome of surgically treated patients was determined by the Derkash score, thoracic outlet syndrome disability scale (TDS), Cervical Brachial Score Questionnaire (CBSQ), Disability of the Arm Shoulder and Hands Dutch language version (DASH-DLV) and Short Form-12 (SF-12) at three, six, 12, and 24 months. RESULTS: Of 856 referred patients, 476 (55.6%) patients were diagnosed with NTOS. Dedicated physiotherapy was successful in 186 patients (39.1%). Surgical treatment was performed in 290 (60.9%) patients of whom 274 were included in the follow up. At a mean follow up of 16.9 ± 9.2 months, significant improvement (p < .001) in TDS, CBSQ, DASH-DLV, and SF-12 scores was seen in the surgical group between baseline and all follow up intervals. Derkash outcome after surgical intervention was excellent in 83 (30.3%), good in 114 (41.6%), fair in 43 (15.7%), and poor in 34 (12.4%) of the patients. Complications occurred in 16 (5.8%) patients, and 32 (10.4%) patients experienced recurrent or persistent NTOS complaints. CONCLUSION: A multidisciplinary care pathway based on the North American SVS reporting standards for NTOS helped to confirm the diagnosis in 56% of patients referred, and guided the selection of patients who might benefit from thoracic outlet decompression surgery after unsuccessful dedicated physiotherapy. Intermediate follow up showed good outcomes in the majority of surgically treated patients.

BACKGROUND: Multiple algorithms exist for treating acute primary upper extremity deep venous thrombosis (pUEDVT) caused by venous thoracic outlet syndrome (VTOS). In this case series, we present the results of our dedicated same admission treatment algorithm. METHODS: All patients between January 2015 and December 2019 with an established acute upper extremity deep venous thrombosis (symptoms <14 days) caused by VTOS were treated according to an algorithm consisting of same admission thrombolysis, transaxillary thoracic outlet decompression (TA-TOD) with extensive venolysis, and venography. If a residual stenosis of the subclavian vein was identified on venography, including by means of low-pressure diagnostic balloon inflation, correction by percutaneous transluminal angioplasty (PTA) was performed. The thoracic outlet syndrome disability scale, the Dutch language version of the disabilities of the arm, shoulder, and hand, and the VEINES-quality of life (VEINES-QOL/VEINES-symptoms) questionnaires were collected during follow-up. RESULTS: In total, 10 patients were treated for acute pUEDVT. After successful thrombolysis (100%) and TA-TOD, immediate venography showed residual stenosis of the subclavian vein in 8 of 10 patients (80%). Low-pressure dilatation of a balloon suited to the geometry of the axillosubclavian vein showed significant tapering in all cases (10/10) after which a formal venous PTA was performed. No stents were used. Mean time to discharge was 6.4 days. All patients were free of symptoms at a mean follow-up period of 34.4 months. Eight of the 10 patients completed follow-up questionnaires and reported a mean thoracic outlet syndrome disability scale of 0.6, mean disabilities of the arm, shoulder, and hand score of 4.2, and a median VEINES-Symptoms of 55.23 (IQR, 12.13), and VEINES-QOL of 55.29 (IQR, 15.42). CONCLUSIONS: A same admission treatment algorithm for acute pUEDVT in patients with VTOS including thrombolysis, TA-TOD with extensive venolysis, and immediate venography with PTA is effective with promising intermediate results.

BACKGROUND: Postoperative analgesia in patients undergoing transaxillary thoracic outlet decompression (TATOD) is challenging because of the invasive surgery, the complex innervation of the axillary region, and the preoperative use of opioids by many patients. Commonly, postoperative pain is managed with additional opioids that introduce well-known sideeffects. To investigate the analgesic efficacy of 2 novel regional anesthesia techniques, we performed a retrospective study comparing the combined pectoral block type 1 and erector spinae block (PECS 1 + ESB) and the pectoral block type 2 (PECS 2) and systemic intravenous opioids regimen (no block) in patients undergoing TATOD. MATERIALS AND METHODS: We performed 10 PECS 1 + ESB and 10 PECS 2 blocks in patients undergoing TATOD. Twenty patients were randomly selected as controls. The primary endpoint was pain. Secondary endpoints were opioid use, nausea, and vomiting. RESULTS: Postoperative maximal numeric rating scale scores on recovery were significantly lower in patients receiving either a PECS 1 + ESB or a PECS 2 block compared with controls without block (no block: median 6.00, interquartile range [IQR] 3.00; PECS 1 + ESB: median 4.50, IQR 4.00; PECS 2: median 4.00, IQR 5.00; P = 0.031). Postoperative intravenous morphine consumption was 43% lower in the PECS 1 + ESB group and 56% lower in the PECS 2 group compared with the group with no block (oral morphine equivalents; no block: mean 16.05 ± SD 6.79 mg; PECS 1 + ESB mean 9.05 ± SD 6.24 mg; PECS 2: mean 7.00 ± SD 6.16; P = 0.03 and P = 0.003, respectively). There was no statistical difference in both nausea and vomitus (no block 45% nausea and 30% vomitus, PECS 1 + ESB 40% nausea and 20% vomitus, PECS 2 10% nausea and 0% vomitus, P = 0.17 and P = 0.14, respectively). CONCLUSIONS: There was a significant reduction in postoperative pain and opioid consumption for patients treated with either the PECS 1 + ESB block or PECS 2.

OBJECTIVE/BACKGROUND: The Dutch College of General Practitioners' guideline on peripheral arterial disease (PAD) provides clear recommendations on the management of PAD. An ankle brachial index (ABI) measurement, prescription of antiplatelet drugs and statins, and supervised exercise therapy (SET) for intermittent claudication (IC) are advised. The aims of this study were to determine the adherence of general practitioners (GPs) to their own guideline on PAD and to evaluate the reliability of primary care ABI measurements. METHODS: This was a cross-sectional study. All patients suspected of having symptomatic PAD who were referred by GPs to a large hospital in 2015 were evaluated regarding three of the guideline criteria: (i) ABI measurement; (ii) prescription of secondary prevention; (iii) initiation of SET. ABI values obtained in primary care and the hospital's vascular laboratory were compared using correlation coefficients and regression analysis. An abnormal ABI was defined as a value <.9 (normal ABI ≥.9). RESULTS: Of 308 potential patients with new onset PAD, 58% (n = 178) had undergone ABI measurement prior to referral. A modest correlation between ABI values obtained in primary care and the vascular laboratory was found (r = .63, p < .001). Furthermore, a moderate reliability was calculated (intraclass correlation coefficient 0.60, 95% confidence interval 0.49-0.69, p < .001). Of the new patients with an abnormal ABI, 59% used antiplatelet drugs and 55% used statins. A referral for SET was initiated by a GP in 10% of new PAD patients with IC symptoms. CONCLUSIONS: Adherence by Dutch GPs to their own society's PAD guideline has room for improvement. The reliability of ABI measurements is suboptimal, whereas rates of prescription of secondary prevention and initiation of SET as primary treatment for IC need upgrading.

Thoracic outlet syndrome (TOS) is a group of conditions thought to be caused by the compression of neurovascular structures going to the upper extremity. TOS is a difficult disease to diagnose, and surgical treatment remains challenging. Many different surgical techniques for the treatment of TOS have been described in the literature and many reasonable to good outcomes have been reported, which makes it hard for surgeons to determine which techniques should be used. Our aim was to describe the rationale, techniques, and outcomes associated with the surgical treatment of TOS. Most patients in our center are treated primarily through a trans-axillary approach. We will elaborate on the technical details of performing trans-axillary thoracic outlet decompression. The essential steps during surgery are illustrated with videos. We focused on the idea behind performing a trans-axillary thoracic outlet decompression in primary cases. Institutional data on the outcomes of this surgical approach are described briefly.

Thoracic outlet syndrome (TOS) is a controversial and uncommon syndrome. Three different diagnoses can be made based on the compressed structure: arterial TOS, venous TOS, and neurogenic TOS. Diagnosing TOS, especially neurogenic TOS, remains difficult since a single diagnostic tool does not exist. Although this resulted in a lot of confusion, standardization of care and outcome improved daily care practice measures in the last decade. Current treatment algorithms consist of both conservative and surgical treatment approaches, which should be chosen depending on the type of TOS and extend of the complaints. Surgical treatment of TOS is performed via thoracic outlet decompression (TOD). TOD surgery includes complete resection of the first rib (cartilage to cartilage), transection of the scalene muscles and complete neurolysis/venolysis or arteriolysis. Four different approaches can be chosen for TOD surgery: the transaxillary (TA), supraclavicular (SC), paraclavicular (PC), and infraclavicular (IC) approach. The TA, SC, and PC approach can be used for every form of TOS. However, the PC approach is mostly used for treating venous TOS. The IC approach has no role in treating neurogenic or arterial TOS and is only used for venous TOS. Every approach has its own benefits and limitations and literature does not agree on what approach is best. Therefore, the used surgical approach for TOD should be based on the surgeon's preference and experience. The aim of this review is to present an overview of the diagnostic pathway and provide an in-depth description of the surgical approach in each form of TOS.
RESUMO
Thoracic outlet syndrome is an uncommon and controversial syndrome. Three different diagnoses can be made based on the compressed structure, arterial TOS, venous TOS, and neurogenic TOS, though combinations do exist as well. Diagnosing NTOS is difficult since no specific objective diagnostic modalities exist. This has resulted in a lot of controversy in recent decades. NTOS remains a clinical diagnosis and is mostly diagnosed based on the exclusion of an extensive list of differential diagnoses. To guide the diagnosis and treatment of TOS, a group of experts published the reporting standards for TOS in 2016. However, a consensus was not reached regarding a blueprint for a daily care pathway in this document. Therefore, we constructed a care pathway based on the reporting standards for both the diagnosis and treatment of NTOS patients. This care pathway includes a multidisciplinary approach in which different diagnostic tests and additional imaging techniques are combined to diagnose NTOS or guide patients in their treatment for differential diagnoses. The aim of the present work is to discuss and explain the diagnostic part of this care pathway.
RESUMO
OBJECTIVE: Venous thoracic outlet syndrome (VTOS) is considered chronic when symptoms and venous stenosis or occlusion are present for >3 months after the initial primary upper extremity deep vein thrombosis event. Many of patients with chronic VTOS receive conservative treatment. However, a subset of these patients will have persistent post-thrombotic syndrome symptoms because of underlying causative anatomy. We present the results of a same admission treatment consisting of' transaxillary thoracic outlet decompression (TA-TOD), external venolysis, and, if necessary, treatment of residual intraluminal lesions with percutaneous transluminal angioplasty (PTA) for chronic VTOS. METHODS: All patients presenting from January 2015 to December 2019 with chronic VTOS and post-thrombotic syndrome complaints were evaluated. Patients with some degree of patency on venography or a chronic occlusion that could be recanalized using PTA preoperatively underwent TA-TOD, external venolysis, and immediate venography. Low-pressure diagnostic balloon inflation after first rib resection was used to identify residual lesions not evident by venography. If found, PTA was performed. Stent placement was reserved for patients with recurrent complaints due to residual lesions that had not been effectively treated by PTA. RESULTS: A total of 40 patients with chronic VTOS were evaluated, of whom 36 were included and treated according to the protocol. The remaining four patients had had a chronic occlusion that could not be recanalized preoperatively and these patients were, therefore, excluded. After TA-TOD, immediate venography showed patent vessels with residual stenosis in 31 patients. Of the five patients who had appeared to have no significant stenosis on venography, two showed narrowing with diagnostic balloon inflation of the subclavian vein, for a total of 33 patients (92%) with residual stenosis after TA-TOD. All 33 patients underwent formal venous PTA. Complications occurred in five patients. At a mean follow-up of 24 months, 30 of the 36 patients (83%) were free of symptoms. The mean thoracic outlet syndrome disability scale score was 1.97 ± 1.9. The mean Disability of the Arm Shoulder and Hand scale score was 16.16 ± 17.4. The median VEINES (venous insufficiency epidemiologic and economic study)-symptoms score was 53.90 (interquartile range, 10.54). The median VEINES-quality of life (QOL) score was 54.22 (interquartile range, 13.93). Finally, the mean 12-item short-form physical QOL component scale score was 47.97 ± 9.02. The thoracic outlet syndrome disability scale and Disability of the Arm Shoulder and Hand scale scores had significantly decreased (P < .01), and the 12-item short-form physical QOL component scale score had significantly improved (P < .01) compared with the baseline scores. A return to daily activities was achieved by 93% of the patients. CONCLUSIONS: The treatment of patients with chronic VTOS using a same admission treatment algorithm consisting of TA-TOD, external venolysis, and PTA is effective. Intermediate follow-up showed a high return to daily activity and significant improvement in functional outcome and physical QOL.

INTRODUCTION: In venous thoracic outlet syndrome (VTOS), pathology around the axillosubclavian vein causes venous compression with the subsequent development of upper extremity symptoms. This case report describes the analysis of all possible compression sites and subsequent treatment of VTOS patients with multiple compression points. REPORT: A 22 year old male presented with severe pain and swelling in his right arm, which persisted after a conservatively managed primary upper extremity deep vein thrombosis. Compression of the axillosubclavian vein was seen both at the level of the pectoralis minor and the costoclavicular spaces. Both compression points were successfully treated by combining thoracic outlet decompression surgery with pectoralis minor tenotomy. DISCUSSION: This report underlines the importance of considering the possibility of multiple compression sites in patients with VTOS. Incomplete surgical release of all compression points leaves patients prone to re-thrombosis and/or persistent post-thrombotic syndrome. Timely recognition of all abnormalities on venography may allow for adjustment of surgical treatment accordingly.
