Whiley PJ, Tamhane R, Hardman DTA. A case series of first rib resection patients assessed with a novel MRI protocol for neurogenic thoracic outlet syndrome. J Surg Case Rep 2023; 2023:rjad672.

Abstract
Selecting patients who will benefit from first rib resection for neurogenic thoracic outlet syndrome (nTOS) is made difficult by the variety of overlap symptoms with other musculoskeletal, neurogenic and psychological disease. A single diagnostic test is not available, and the diagnosis is typically made based on clinical findings and history. This case series assessed the utility of magnetic resonance imaging (MRI), with the patient's arm placed in a symptom provoking position above the head, as a component of diagnosis nTOS and selection of patients to offer surgery. Outcomes from first rib resection were assessed using the guidelines of The Society for Vascular Surgery for Thoracic Outlet Syndrome. The cases demonstrate that the loss of perineural fat signal on MRI of the brachial plexus with the arm in the provocative position is a useful tool for assessing patients who would benefit from first rib resection for nTOS.

Abstract
Thoracic outlet syndrome (TOS) is a disease pattern that involves compression of neurologic venous or arterial structures as they pass through the thoracic outlet. TOS was first described as a vascular complication arising from the presence of a cervical rib. Over time, a better understanding of TOS has led to its wide range of presenting symptoms being divided into three distinct groups: arterial, venous, and neurogenic. Of the known cases, the current estimates of the incidence of neurogenic TOS, venous TOS, and arterial TOS are 95%, 3%, and 1%, respectively. The different types of TOS have completely different presentations, requiring expertise in the diagnosis, management, and treatment unique to each. We present our evaluation, diagnosis, and management method of TOS patients, with specific attention paid to the transaxillary approach.

General Overview and Diagnostic (Imaging) Techniques for Neurogenic Thoracic Outlet Syndrome. Diagnostics (Basel) 2023; 13:diagnostics13091625. [PMID: 37175016 PMCID: PMC10178617 DOI: 10.3390/diagnostics13091625] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 04/26/2023] [Accepted: 05/02/2023] [Indexed: 05/15/2023] Open
Abstract
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.

Abstract
PURPOSE It remains unclear whether the first rib resection, performed via a supraclavicular (SCFRR) or transaxillary (TAFRR) approach, is necessary for patients with neurogenic thoracic outlet syndrome (nTOS). In a systematic review and meta-analysis, we performed a direct comparison of patient-reported functional outcomes following different surgical approaches for nTOS. METHODS The authors searched PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, Google Scholar, and the gray literature. Data were extracted based on the procedure type. Well-validated patient-reported outcome measures were analyzed in separate time intervals. Random-effects meta-analysis and descriptive statistics were used where appropriate. RESULTS Twenty-two articles were included, with 11 discussing SCFRR (812 patients), 6 discussing TAFRR (478 patients), and 5 discussing rib-sparing scalenectomy (RSS; 720 patients). The mean difference between preoperative and postoperative Disabilities of the Arm, Shoulder and Hand score was significantly different comparing RSS (43.0), TAFRR (26.8), and SCFRR (21.8). The mean difference between preoperative and postoperative visual analog scale scores was significantly higher for TAFRR (5.3) compared to SCFRR (3.0). Derkash scores were significantly worse for TAFRR compared to RSS or SCFRR. RSS had a success rate of 97.4% based on Derkash score, followed by SCFRR and TAFRR at 93.2% and 87.9%, respectively. RSS had a lower complication rate compared to SCFRR and TAFRR. There was a difference in complication rates: 8.7%, 14.5%, and 3.6% for SCFRR, TAFRR, and RSS, respectively. CONCLUSIONS Mean differences in Disabilities of the Arm, Shoulder and Hand scores and Derkash scores were significantly better for RSS. Higher complication rates were reported after the first rib resection. Our findings suggest that RSS is an effective option for the treatment of nTOS. TYPE OF STUDY/ LEVEL OF EVIDENCE Therapeutic IV.

J Pharmacol Exp Ther 2022; 383:227-237. [PMID: 36116794 DOI: 10.1124/jpet.122.001313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 09/06/2022] [Indexed: 01/07/2023] Open
Abstract
A positive response to scalene muscle block (SMB) is an important indication for the diagnosis of thoracic outlet syndrome. Lidocaine injection is commonly used in clinical practice in SMB, although there have been some cases of misdiagnosis. Botulinum toxin A (BTX-A) is one of the therapeutic agents in SMB, but whether it is also indicated for SMB diagnosis is controversial. To evaluate the muscle block efficiency of these two drugs, the contraction strength was repeatedly recorded on tibialis anterior muscle in rats. It was found that at a safe dosage, 2% lidocaine performed best at 40 μL, but it still exhibits an unsatisfactory partial blocking efficiency. Moreover, neither lidocaine injection in combination with epinephrine or dexamethasone nor multiple locations injection could improve the blocking efficiency. On the other hand, injections of 3, 6, and 12 U/kg BTX-A all showed almost complete muscle block. Gait analysis showed that antagonistic gastrocnemius muscle, responsible for heel rising, was paralyzed for nonspecific blockage in the 12 U/kg BTX-A group, but not in the 3 U/kg or 6 U/kg BTX-A group. Cleaved synaptosomal associated protein 25 (c-SNAP 25) was stained to test the transportation of BTX-A, and was additionally observed in the peripheral muscles in 6 and 12 U/kg groups. c-SNAP 25, however, was barely detectable in the spinal cord after BTX-A administration. Therefore, our results suggest that low dosage of BTX-A may be a promising option for the diagnostic SMB of thoracic outlet syndrome. SIGNIFICANCE STATEMENT: Muscle block is important for the diagnosis and treatment of thoracic outlet syndrome and commonly performed with lidocaine. However, misdiagnosis was observed sometimes. Here, we found that intramuscular injection of optimal dosage lidocaine only partially blocked the muscle contraction in rats, whereas low-dosage botulinum toxin, barely used in diagnostic block, showed almost complete block without affecting the central nervous system. This study suggests that botulinum toxin might be more suitable for muscle block than lidocaine in clinical practice.

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

Ann Vasc Surg 2022; 83:53-61. [PMID: 34998937 DOI: 10.1016/j.avsg.2021.12.080] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 12/05/2021] [Accepted: 12/22/2021] [Indexed: 11/01/2022]
Abstract
OBJECTIVES Congenital abnormalities of the first rib (ABNFR) are a rare cause of thoracic outlet syndrome (TOS). The range of abnormalities have not been clearly documented in the literature. Surgical decompression in these patients presents with increased complexity secondary to anomalous anatomy. Our goal is to review an institutional experience of first rib resection (FRR) performed for ABNFRs, to present a novel classification system, and to analyze outcomes according to clinical presentation. METHODS A prospectively collected database was used to identify individuals with ABNFRs who underwent FRR for TOS between 1990-2021. These individuals were identified both by preoperative imaging and intraoperative descriptions of the first rib after resection. Demographic, clinical, perioperative and pathological data were reviewed. ABNFRs were classified into three categories according to anatomical criteria: (I) Hypoplastic, (II) Fused, and (III) Hyperplastic. Outcomes were rated using the standardized Quick Disability of Arm Shoulder and Hand Scores (QDS), Somatic Pain Scores (SPS) and Derkash Scores (DkS). RESULTS Among the 2200 cases of TOS, there were 19 patients (0.8%) with ABNFR who underwent FRR. Average age at surgery was 30.5 (range 11-74), including 13 men and 6 women. Presentations included 9 arterial (ATOS), 6 neurogenic (NTOS), and 4 venous (VTOS) cases. There were 6 class I, 6 class II, and 7 class III ABNFRs. Among 6 NTOS patients there were 4 abnormal nerve conduction tests and 5 positive anterior scalene muscle blocks. Among the 9 patients with ATOS, thrombolysis was attempted in 5 patients, and of these, 3 ultimately required surgical thrombectomy. Of 4 VTOS cases, 2 were managed with thrombolysis, and 2 with anticoagulation alone. The approach for FRR was transaxillary in all patients. Secondary procedures included 1 pectoralis minor tenotomy, 1 scalenectomy, and 1 contralateral rib resection. No major neurological or vascular complications occurred. There was 1 patient who required surgical evacuation of a hematoma. Intraoperative chest tube placement was required in 5 patients secondary to pleural entry during dissection. There was an overall improvement in symptoms over an average follow-up of 7.4 months. QDS reduced from 49.7 pre-op to 22.1 (p<.05). SPS improved from 3.4 pre-op to 1.8. DkS scores were good to excellent in 79% of patients. Residual symptoms were noted in 7, and ATOS accounted for 5 (70%) of these. All patients were able to return to work. CONCLUSIONS Despite increased complexity, ABNFRs may be safely resected via transaxillary approach with low incidence of complications, very good symptom relief, and excellent outcomes. Congenital ABNFRs may by classified into three categories (hypoplastic, fused, and hyperplastic) with a variety of presentations, including ATOS, NTOS, and VTOS. Classification of ABNFRs allows concise description of abnormal anatomy which facilitates comparison between series and provides direction for surgical management to ultimately optimize patient outcomes.

Abstract
OBJECTIVE Over the past two decades, vascular surgeons have successfully incorporated endovascular techniques to the routine care of patients with arterial thoracic outlet syndrome (ATOS). However, no reports have documented the impact of endovascular therapy. This study describes the trends in management of ATOS by vascular surgeons and outcomes after both endovascular and open repair of the subclavian artery. METHODS We queried a single-institution, prospectively maintained thoracic outlet syndrome database for ATOS cases managed by vascular surgeons. For comparison, cases were divided into two equal time periods, January 1986 to August 2003 (P-1) vs September 2003 to March 2021 (P-2), and by treatment modality, open vs endovascular. Clinical presentation, outcomes, and the involvement of vascular surgeons in endovascular therapy were compared between groups. RESULTS Of 2200 thoracic outlet syndrome cases, 51 were ATOS (27 P-1, 24 P-2) and underwent 50 transaxillary decompressive operations. Forty-eight cases (92%) presented with ischemic symptoms. Thrombolysis was done in 15 (29%). During P-1, vascular surgeons performed none of the catheter-based interventions. During P-2, vascular surgeons performed 60% of the angiograms, 50% of thrombolysis, and 100% of stent grafting. Subclavian artery pathology included 16 aneurysms (31%), 15 stenoses (29%), and 19 occlusions (37%). Compared with open aneurysmal repair, endovascular stent graft repairs took less time (241 vs 330 minutes; P = .09), incurred lower estimated blood loss (103 vs 150 mL; P = .36), and had a shorter length of stay (2.4 vs 5.0 days; P = .10). Yet the endovascular group had decreased primary (63% vs 77%; P = .481), primary assisted (75% vs 85%; P = .590), and secondary patency rates (88% vs 92%; P = .719), at a mean follow-up time of 3.0 years for the endovascular group and 6.9 years for the open group (P = .324). These differences did not achieve statistical significance. Functionally, 84% of patients were able to resume work or school. A majority of patients (88%) had a good to excellent functional outcome based on their Derkash score. Somatic pain scores and QuickDASH (disabilities of the arm, shoulder, and hand) scores decreased postoperatively, 2.9 vs 0.8 (P = .015) and 42.6 vs 12.6 (P = .004), respectively. CONCLUSIONS This study describes the evolving role of endovascular management of ATOS over the past two decades and documents the expanded role of vascular surgeons in the endovascular management of ATOS at a single institution. Compared with open repair, stent graft repair of the subclavian artery may be associated with shorter operative times, less blood loss, but decreased patency, without changes in long-term functional outcomes.

Abstract
OBJECTIVES The aim was to determine long-term outcomes over a decade after first rib resection (FRR) in patients with neurogenic thoracic outlet syndrome (NTOS). A secondary aim was to investigate correlation of residual rib stump with long-term symptoms. METHODS This ambispective cohort included patients who underwent transaxillary FRRs for NTOS between 1998 and 2007. Short-term outcomes at 3-month clinical follow-up were retrospectively collected from medical records. Patients who agreed to participate in the study were invited to a long-term clinical follow-up in 2019. Disabilities of Arm, Shoulder, and Hand Score and Cervical Brachial Symptom Questionnaire were used. A chest X-ray limited to a clavicular projection was taken, and the length of the residual first rib was measured. RESULTS Twenty patients {mean age 41.8 [standard deviation (SD): 10.3 years]} who underwent 27 FRRs participated in the study. The mean follow-up time was 14.9 (SD: 3.6) years. Excellent or good recovery was noted after 16 (59.3% of operated arms) operations in the short-term follow-up and 22 (81.5%) operations in the long-term follow-up. No reoperations were necessary for residual symptoms. The mean Cervical Brachial Symptom Questionnaire score was 26.7 (SD: 28.2) (maximum 120), and the Disabilities of Arm, Shoulder, and Hand Score was 21.1 (SD: 18.4) (maximum 100) points. Twenty-six patients (96.3%) had a noticeable residual first rib stump. The mean length of the residual first rib was 28.9 (SD: 9.5) mm. More than 30-mm rib stump did not indicate a worse long-term outcome. CONCLUSIONS This study showed good long-term outcome without symptom recurrence after FRR for NTOS. In most patients, after surgery, quality of life and ability to work improved. Residual rib stump length was not associated with the treatment outcome.

Abstract
The cervical rib syndrome occurs when the interscalene triangle is occupied by a cervical rib, displacing the brachial plexus and the subclavian artery forward, which can cause pain and muscle spasms. The objective of this study is to discuss diagnosis of the cervical rib syndrome and treatment possibilities. This therapeutic challenge describes clinical and surgical management of a 37-year-old female patient with upper limb arterial occlusion caused by a cervical rib.

Abstract
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.

Abstract
BACKGROUND Thoracic outlet syndrome (TOS) surgery is relatively rare and controversial, given the challenges in diagnosis as well as wide variation in symptomatic and functional recovery. Our aims were to measure trends in utilization of TOS surgery, complications, and mortality rates in a nationally representative cohort and compare higher versus lower volume centers. METHODS The National Inpatient Sample was queried using International Classification of Diseases, Ninth Revision, codes for rib resection and scalenectomy paired with axillo-subclavian aneurysm (arterial [aTOS]), subclavian deep vein thrombosis (venous [vTOS]), or brachial plexus lesions (neurogenic [nTOS]). Basic descriptive statistics, nonparametric tests for trend, and multivariable hierarchical regression models with random intercept for center were used to compare outcomes for TOS types, trends over time, and higher and lower volume hospitals, respectively. RESULTS There were 3,547 TOS operations (for an estimated 18,210 TOS operations nationally) performed between 2010 and 2015 (89.2% nTOS, 9.9% vTOS, and 0.9% aTOS) with annual case volume increasing significantly over time (P = 0.03). Higher volume centers (≥10 cases per year) represented 5.2% of hospitals and 37.0% of cases, and these centers achieved significantly lower overall major complication (defined as neurologic injury, arterial or venous injury, vascular graft complication, pneumothorax, hemorrhage/hematoma, or lymphatic leak) rates (adjusted odds ratio [OR] 0.71 [95% confidence interval 0.52-0.98]; P = 0.04], but no difference in neurologic complications such as brachial plexus injury (aOR 0.69 [0.20-2.43]; P = 0.56) or vascular injuries/graft complications (aOR 0.71 [0.0.33-1.54]; P = 0.39). Overall mortality was 0.6%, neurologic injury was rare (0.3%), and the proportion of patients experiencing complications decreased over time (P = 0.03). However, vTOS and aTOS had >2.5 times the odds of major complication compared with nTOS (OR 2.68 [1.88-3.82] and aOR 4.26 [1.78-10.17]; P < 0.001), and ∼10 times the odds of a vascular complication (aOR 10.37 [5.33-20.19] and aOR 12.93 [3.54-47.37]; P < 0.001], respectively. As the number of complications decreased, average hospital charges also significantly decreased over time (P < 0.001). Total hospital charges were on average higher when surgery was performed in lower volume centers (<10 cases per year) compared with higher volume centers (mean $65,634 [standard deviation 98,796] vs. $45,850 [59,285]; P < 0.001). CONCLUSIONS The annual number of TOS operations has increased in the United States from 2010 to 2015, whereas complications and average hospital charges have decreased. Mortality and neurologic injury remain rare. Higher volume centers delivered higher value care: less or similar operative morbidity with lower total hospital charges.

Abstract
OBJECTIVES Robotic first rib resection (R-FRR) is an emerging approach in the field of thoracic outlet syndrome (TOS) that has technical advantages over traditional open approaches, including superior exposure of the first rib and freedom from retracting neurovascular structures. We set out to define the safety of R-FRR and compare it with that of the conventional supraclavicular approach (SC-FRR). METHODS We queried a prospectively maintained, single-surgeon, single-institution database for all FRR operations performed for neurogenic TOS and venous TOS. Preoperative, intraoperative, and complications were compared between approaches. RESULTS Seventy-two R-FRRs and 51 SC-FRRs were performed in 66 and 50 patients, respectively. These groups were not significantly different in age, body mass index, sex, type of TOS, or preoperative use of opioids. Length of procedure and hospital stay were not different between groups. Postoperative inpatient self-reported pain (visual analog scale score 4.7 vs 5.2; P = .049) and administered morphine milligram equivalents (37.5 vs 81.1 MME, P < .001) were significantly lower in R-FRR than SC-FRR. Brachial plexus palsy was less frequent after R-FRR than SC-FRR (1% vs 18%, P = .002) and resolved by 4 months in call cases. All cases were sensory palsies with the exception of 2 motor palsies, which were both in the SC-FRR group. In multivariable analyses, R-FRR was independently associated with less frequent total complications than SC-FRR (P = .002; odds ratio, 0.08; 95% confidence interval, 0.02-0.39). CONCLUSIONS R-FRR provides outstanding exposure of the first rib and eliminates retraction of the brachial plexus and its consequences.

Abstract
OBJECTIVE Although the supraclavicular approach has been widely adopted for cervical rib resection, a transaxillary approach has been favored by many. We have reviewed more than two decades of experience with decompression of the thoracic outlet to treat thoracic outlet syndrome (TOS) in patients with complete cervical ribs using a novel transaxillary approach. METHODS A prospectively maintained database of patients undergoing surgery for TOS was searched for patients with complete (class 3 and 4) cervical ribs from 1997 to 2019. All these patients had undergone transaxillary resection using a technique in which the cervical and first ribs were separated and then individually resected. The data abstracted included patient demographics, symptoms, surgical details, and complications. The outcomes were contemporaneously assessed clinically and using standardized functional tools: somatic pain scale (SPS) and Quick Disabilities of the Arm, Hand, and Shoulder questionnaire (QuickDASH). The cervical rib data were organized and reported in accordance with the Society for Vascular Surgery reporting standards. RESULTS During the study period, 1506 patients had undergone surgery for TOS at our institution. Of these 1506 patients, 38 had undergone complete transaxillary resection of 40 fully formed cervical ribs (10 class 3 and 30 class 4). Of these 38 patients, 74% were women. The presentations had been neurogenic (65%), arterial (31%), and venous (5%). The average initial SPS and QuickDASH score was 6.4 and 50, respectively. The duration of surgery averaged 141 minutes, blood loss was 65 mL, and length of stay was 2.1 days. None of the patients had experienced brachial plexus, phrenic, or long thoracic nerve injury. The average follow-up period was 65 months. The final mean postoperative SPS and QuickDASH scores were lower than the scores at presentation (SPS score, 6.4 vs 1.2; P < .001; QuickDASH score, 50 vs 17; P < .001). CONCLUSIONS To the best of our knowledge, the present study is the largest reported experience of resection of fully formed cervical ribs using a transaxillary approach that allowed for individual dissection and removal of cervical and first rib segments. This technique has proved to be successful, with low morbidity and reliable improvement in patient symptom and disability scores. Based on these reported outcomes, this novel approach to transaxillary resection of fully formed cervical ribs should be considered a safe and effective operation.

Abstract
BACKGROUND Short-term outcomes in patients with all forms of TOS have been widely reported in the literature and have established that rib resection can be beneficial in decompressing the thoracic outlet and relieving pressure on traversing structures. We sought to determine long-term functional outcomes using the Disability of the Arm, Shoulder, and Hand (QuickDASH) survey in patients with TOS who underwent rib resection. METHODS Clinical records for patients who underwent rib resection for TOS at a single institution were retrospectively reviewed. All patients were contacted via telephone and long-term functional outcome was assessed at latest follow-up via the 11-item version of the QuickDASH questionnaire. Demographics, TOS type, preoperative QuickDASH score, and athletic status were recorded. Patients were asked if they returned to baseline activity since their surgery, would have the procedure again, and if they were subjectively better postoperatively. RESULTS From 2000 to 2018, 261 patients underwent rib resection surgery. One hundred seventy patients (65.1%) were able to be contacted via telephone for long-term follow-up. A total of 188 surgeries (102 neurogenic thoracic outlet syndrome, 82 venous thoracic outlet syndrome, 4 arterial thoracic outlet syndrome) were performed in these 170 patients. The mean follow-up time for the cohort was 5.3 years (range 1-18). Overall, 167 (88.9%) patients returned to baseline activity postoperatively. Postop QuickDASH decreased to 12 from 44 preoperatively for the cohort. CONCLUSIONS First rib resection and thoracic outlet decompression for all forms of TOS is a durable surgical treatment which results in excellent long-term functional outcomes as determined by both the QuickDASH score and subjective patient reporting.

Cervical Rib Synostosis to the First Rib: A Rare Anatomic Variation. World Neurosurg 2020; 138:187-192. [PMID: 32169617 DOI: 10.1016/j.wneu.2020.03.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Revised: 02/29/2020] [Accepted: 03/02/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND Congenital anatomic variations exist in human anatomy, which create both diagnostic and treatment challenges. Understanding the osteologic and radiographic anatomy of supernumerary ribs arising from the cervical spine and recognizing the morphologic variations thereof is of great importance to clinicians, radiologists, and surgeons alike. CASE DESCRIPTION This case study describes osteologic morphology and radiologic characteristics of a rare anatomic variant of a cervical rib (CR): a unilateral, right-sided CR synostosis to the first thoracic rib of a 50-year-old South African man of African ancestry. The characteristic features included increased angulation, widening of the body, and shortening of the length of the right-sided first thoracic rib. The synostosis of the CR shaft was at the level of the angle of the first thoracic rib. The widest aspect of the first thoracic rib was close to the site of fusion, namely the angle, with the mediolateral length approximately 34.51 mm. This is in contrast to the contralateral first thoracic rib measuring, at its widest, 26.39 mm. The CR was located approximately 3.34 mm superiorly to the first thoracic rib at the cervical articular facet. The CR presented with a well-defined head, which is small and rounded with the inclusion of an articular facet. Thereafter, it presented with a short neck, just over half the length of the inferiorly placed first thoracic rib, and a similar sized articulating facet at the tubercle. The appearance of the trabecular bone pattern on radiographs is in keeping with the contralateral left first rib, although altered in accordance with the gross osteologic appearance described earlier. Furthermore, the radiographs highlight an elliptical lucent-zone within the trabecular bone demonstrating decreased density centrally with a thin rim of sclerotic cortical bone peripherally. This is consistent with classical rib architecture in cross-section representing the CR shaft site of fusion to the first thoracic rib. The CR synostosis to the first thoracic rib represents a novel complex, termed by the authors as a cervicothoracic rib complex. CONCLUSION The present report refers to the osteologic and radiographic description and comparison of a unilateral, right-sided CR synostosis to a first thoracic rib. The clinical implications of CRs may consist of neurologic, vascular complications, and functional deficits of the involved limb associated with thoracic outlet syndrome (TOS). A CR synostosis to the first thoracic rib represents an associated increased risk of vascular injury, with poorer operative outcomes associated with TOS. This case study is of particular importance to vascular surgeons and neurosurgeons involved with surgical planning and intervention strategies relating to CRs and TOS.
