Thoracic Outlet Syndrome in the Pediatric and Young Adult Population.

PURPOSE: This study aimed to assess both nonsurgical and operative treatment outcomes of pediatric and young adult patients with thoracic outlet syndrome (TOS) at a tertiary care pediatric hospital. METHODS: A retrospective chart review of patients diagnosed with TOS, who were seen between January 2010 and August 2022 at a tertiary care pediatric hospital, was conducted. Collected pre- and postoperative data included symptoms, provocative testing (ie, Roo's, Wright's, and Adson's tests), participation in sports or upper-extremity activities, additional operations, and surgical complications. Assessment of operative treatment efficacy was based on pre- and post-provocative testing, pain, venogram results, alleviation of symptoms, and return to previous activity level 6 months after surgery. RESULTS: Ninety-six patients, (70 females and 26 males) with an average age at onset of 15 ± 4 (4-25) years, met the inclusion criteria for TOS. Among them, 27 had neurogenic TOS, 29 had neurogenic and vasculogenic TOS, 20 had vasculogenic TOS, 19 had Paget-Schroetter Syndrome, and one was asymptomatic. Twenty-six patients were excluded because of less than 6 months of follow-up. Of the remaining 70, 6 (8.6%) patients (4 bilateral and 2 unilateral) underwent nonoperative management with activity modification and physical therapy only, and one was fully discharged because of complete relief of symptoms. Sixty-four (90.1%) patients (45 bilateral and 19 unilateral) underwent surgery. A total of 102 operations were performed. Substantial improvements were observed in provocative maneuvers after surgery. Before surgery, 79.7% were involved in sports or playing musical instruments with repetitive overhead activity, and after surgery, 86.2% of these patients returned to their previous activity level. CONCLUSIONS: Few patients were successfully managed with nonoperative activity modification and physical therapy. In those requiring surgical intervention, first or cervical rib resection with scalenectomy using a supraclavicular approach provided resolution of symptoms with 86.2% of patients being able to return to presymptom sport or activity level. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Development and validation of a prediction model for outcomes after transaxillary first rib resection for neurogenic thoracic outlet syndrome following strict Society for Vascular Surgery diagnostic criteria.

OBJECTIVE: Neurogenic thoracic outlet syndrome (NTOS) is the most common form of thoracic outlet syndrome. However, NTOS has remained difficult to diagnose and treat successfully. The purpose of the present study was to generate a predictive clinical calculator for postoperative outcomes after first rib resection (FRR) for NTOS. METHODS: We performed a retrospective review of patients who had undergone FRR for NTOS at a single tertiary care institution between 2016 and 2020. A multivariate stepwise logistic regression analysis was performed to assess the association of the percentage of improvement after FRR with the patient baseline characteristics, pertinent clinical characteristics, and diagnostic criteria set by the Society for Vascular Surgery. The primary outcome was subjective patient improvement after FRR. A prediction risk calculator was developed using backward stepwise multivariate logistic regression coefficients. Bootstrapping was used for internal validation. RESULTS: A total of 208 patients (22.2% male; mean age, 35.8 ± 12.8 years; median follow-up, 44.9 months) had undergone 243 FRRs. Of the 208 patients, 94.7% had had symptoms localized to the supraclavicular area, and 97.6% had had symptoms in the hand. All the patients had had positive symptoms reproduced by the elevated arm stress test and upper limb tension test. Another reasonably likely diagnosis was absent for all the patients. Of the 196 patients who had received a lidocaine injection, 180 (93.3%) had experienced improvement of NTOS symptoms. Of the 95 patients who had received a Botox injection, 82 (74.6%) had experienced improvement of NTOS symptoms. Receiver operating characteristic curve analysis was used to assess the model. The area under the curve for the backward stepwise multivariate logistic regression model was 0.8. The multivariate logistic regression analyses revealed that the significant predictors of worsened clinical outcomes included hand weakness (adjusted odds ratio [aOR], 4.28; 95% confidence interval [CI], 1.04-17.74), increasing age (aOR, 0.93; 95% CI, 0.88-0.99), workers' compensation or litigation case (aOR, 0.09; 95% CI, 0.01-0.82), and symptoms in the dominant hand (aOR, 0.20; 95% CI, 0.05-0.88). CONCLUSIONS: Using retrospective data from a single-institution database, we have developed a prediction calculator with moderate to high predictive ability, as demonstrated by an area under the curve of 0.8. The tool (available at: https://jhhntosriskcalculator.shinyapps.io/NTOS_calc/) is an important adjunct to clinical decision-making that can offer patients and providers realistic and personalized expectations of the postoperative outcome after FRR for NTOS. The findings from the present study have reinforced the diagnostic criteria set by the Society for Vascular Surgery. The calculator could aid physicians in surgical planning, referrals, and counseling patients on whether to proceed with surgery.

Management of Paget-Schroetter Syndrome: a Systematic Review and Meta-Analysis.

OBJECTIVE: Currently, there is no consensus on the optimal management of Paget-Schroetter syndrome (PSS). The objective was to summarise the current evidence for management of PSS with explicit attention to the clinical outcomes of different management strategies. DATA SOURCES: The Cochrane, PubMed, and Embase databases were searched for reports published between January 1990 and December 2021. REVIEW METHODS: A systematic review and meta-analysis was conducted following PRISMA 2020 guidelines. The primary endpoint was the proportion of symptom free patients at last follow up. Secondary outcomes were success of initial treatment, recurrence of thrombosis or persistent occlusion, and patency at last follow up. Meta-analyses of the primary endpoint were performed for non-comparative and comparative reports. The quality of evidence was assessed using the GRADE approach. RESULTS: Sixty reports were included (2 653 patients), with overall moderate quality. The proportions of symptom free patients in non-comparative analysis were: anticoagulation (AC), 0.54; catheter directed thrombolysis (CDT) + AC, 0.71; AC + first rib resection (FRR), 0.80; and CDT + FRR, 0.96. Pooled analysis of comparative reports confirmed the superiority of CDT + FRR compared with AC (OR 13.89, 95% CI 1.08 - 179.04; p = .040, I2 87%, very low certainty of evidence), AC + FRR (OR 2.29, 95% CI 1.21 - 4.35; p = .010, I2 0%, very low certainty of evidence), and CDT + AC (OR 8.44, 95% CI 1.12 - 59.53; p = .030, I2 63%, very low certainty of evidence). Secondary endpoints were in favour of CDT + FRR. CONCLUSION: Non-operative management of PSS with AC alone results in persistent symptoms in 46% of patients, while 96% of patients managed with CDT + FFR were symptom free at end of follow up. Superiority of CDT + FRR compared with AC, CDT + AC, and AC + FRR was confirmed by meta-analysis. The overall quality of included reports was moderate, and the level of certainty was very low.

Successful paraclavicular surgical decompression for recurrent venous thoracic outlet syndrome following transaxillary first rib resection in an elite athlete.

OBJECTIVES: Recurrent effort thrombosis after prior surgical intervention for venous thoracic outlet syndrome (TOS) is an uncommon problem, and there are multiple alternative surgical approaches in the management of recurrent venous TOS. METHODS: We present a case of a 23 year-old female professional athlete who presented with arm swelling, pain, and recurrent effort thrombosis after prior transaxillary rib resection. Imaging at our institution revealed subclavian vein thrombosis, confirmed with dynamic venography, as well as a remnant first rib. RESULTS: Thrombolysis of the subclavian vein and balloon angioplasty was followed by paraclavicular thoracic outlet decompression with complete first rib resection. Success was confirmed with intraoperative dynamic venography demonstrating a patent subclavian vein and resulted in complete elimination of symptoms. CONCLUSION: Additional surgical decompression with complete medial first rib resection of remnant rib, which was potentially causing compression of the subclavian vein, may be necessary to prevent recurrent venous compression and thrombosis for venous TOS.

Considerations for Surgical Treatment of Neurogenic Thoracic Outlet Syndrome: A Meta-Analysis of Patient-Reported Outcomes.

PURPOSE: It remains unclear whether first rib resection (FRR), 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 FRR. Our findings suggest that RSS is an effective option for the treatment of nTOS. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Predictors of the need for rib resection in minimally invasive retroperitoneal approach for oblique lateral interbody fusion at upper lumbar spine (L1-2 and L2-3).

BACKGROUND: This study aimed to identify factors that can predict the need for rib resection in a minimally invasive, oblique retroperitoneal approach for upper lumbar interbody fusion (OLIF at L1-3) using modern tubular retractors. METHODS: Eighty-six patients, who underwent L1-2 and/or L2-3 OLIF at a single institution, were included. Decision for rib resection was made through intraoperative fluoroscopic view (true lateral view of the desired level). Patients were divided into two groups according to rib resection (rib resection and non-rib resection groups). Baseline demographics, surgical and radiographic data, including coronal/sagittal spinopelvic parameters and perioperative complications, were compared between the groups. Logistic regression analysis was performed to identify the factors predicting the need for rib resection. RESULTS: The study cohort comprised 31 patients in the rib resection group and 55 patients in the non-rib resection group. There was no significant inter-group difference in terms of the baseline demographics. A total of 79% patients undergoing the two-level (both L1-2 and L2-3) procedures were rib-resected, while 81.6% of the patients undergoing the L2-3 level alone were not rib-resected. Endplate injuries occurred more commonly in the non-rib resection group (3% vs. 14%). Pleural laceration was observed in 6% of the patients in the rib resection group. The mean T10-L2 kyphosis was larger in the rib resection group than in the non-rib resection group (14.9° vs. 6.6°, P = 0.031). Multivariate logistic regression analysis identified the following independent predictors of the need for rib resection: an L1-2 inclusive procedure; T10-L2 kyphosis > 15.9°; and the apex of the coronal curve located above L2. CONCLUSION: The need for rib resection should be expected when performing L1-2 inclusive procedure. Even in the L2-3 alone case, aggressive decision-making for intraoperative rib resection might be required for an appropriate tubular retractor position, especially for patients with thoracolumbar kyphosis and apex vertebra of the major coronal curve located above L2.

[Chest wall repair after extensive resections]. / Rezul'taty vosstanovleniya karkasa grudnoi stenki posle obshirnykh rezektsii.

OBJECTIVE: To analyze the outcomes after different methods of post-resection chest wall defect reconstruction. MATERIAL AND METHODS: The study included 41 patients aged 22-73 years who underwent chest wall repair with local tissues and synthetic materials. Twelve (29.3±7.1%) patients had sarcoma, 9 (21.9±5.9%) - non-small cell lung cancer (NSCLC) with invasion of the chest, 9 (21.9±5.9%) - metastatic lesions, 8 (19.5±6.2%) - benign tumors, 2 (4.8±3.4%) - breast cancer with invasion of the chest wall, 1 (2.4±2.4%) - desmoid tumor. Seven patients were diagnosed with T3N0M0, 1 - T3N2M0, 1 - T2N0M1b (oss). Among patients with NSCLC with invasion into the chest wall, squamous cell cancer was verified in 4 (44.4±16.6%) patients, adenocarcinoma - in 4 (44.4±16.6%), neuroendocrine tumor - in 1 (11.2±10.5%) patient. Stages of surgeries are presented. RESULTS: We analyzed treatment outcomes in 41 patients. Five (12.2%) patients had seroma, hemothorax, thoracopleural fistula, subcutaneous emphysema and fatal asystole. There were no postoperative complications associated with paradoxical breathing. CONCLUSION: Accurate morphological verification prior to treatment is valuable to determine the stages of combined treatment of chest wall tumors. Chest wall defect closure with own tissues and synthetic materials is necessary after extensive resections. A multidisciplinary approach involving thoracic and plastic surgeons is needed.

Long-Term Outcomes of Nonoperative and Surgical Management of Paget-Schroetter Syndrome.

PURPOSE: In Paget-Schroetter Syndrome (PSS), subclavian vein thrombosis is caused by external compression of the subclavian vein at the costoclavicular junction. Paget-Schroetter Syndrome can be treated nonoperatively, surgically, or with a combination of treatments. Nonoperative management consists, in most cases, of anticoagulation (AC) or catheter-directed thrombolysis (CDT). With surgical management, decompression of the subclavian vein is performed by resection of the first rib. No prospective randomized trials are available to determine whether nonoperative or surgical management is superior. We report our long-term outcomes of both nonoperative and surgically treated patients. MATERIALS AND METHODS: We retrospectively analyzed all patients with PSS who were treated between January 1990 and December 2015. Patients were divided based on primary nonoperative or primary surgical therapy. Long-term outcomes regarding functional outcomes were assessed by questionnaires using the "Disability of the Arm, Shoulder, and Hand" (DASH) questionnaire, a modified Villalta score, and a disease-specific question regarding lifestyle changes. RESULTS: In total, 91 patients (95 limbs) were included. Seventy patients (73 limbs) were treated nonoperatively and 21 patients (22 limbs) surgically. Questionnaires were returned by 67 patients (70 limbs). The mean follow-up was 184 months (range, 43-459 months). All functional outcomes were better in the surgical group compared with the nonoperatively treated group (DASH general 3.11 vs 9.86; DASH work 0.35 vs 11.47; DASH sport 5.85 vs 17.98, and modified Villalta score 1.11 vs 3.20 points). Surgically treated patients were more likely to be able to continue their original lifestyle and sports activities (84% vs 40%, p=0.005). Patients with recurrence of thrombosis or the need for surgical intervention after primary nonoperative management reported worse functional outcomes. CONCLUSION: Surgical management of PSS with immediate CDT followed by first rib resection leads to excellent functional outcomes with low risk of complications. The results of nonoperative management in our non-matched retrospective comparative series were satisfactory, but resulted in worse functional outcomes and more patients needing to adjust their lifestyle compared with surgically treated patients. CLINICAL IMPACT: Patients with Paget-Schroetter Syndrome and their attending physicians are burdened by the lack of evidence concerning the optimal treatment of this entity. Case series comparing the outcomes of non-operative treatment with surgical treatment are scarce and often not focussed on functional outcomes. Data from this series can aid in the shared decision making after diagnosis of Paget-Schroetter Syndrome. Functional outcomes of non-operative management can be satisfying although high demand patient who are not willing to alter their daily activities are probably better off with surgical management.

Robot-assisted transthoracic first rib resection for venous thoracic outlet syndrome.

BACKGROUND: Venous thoracic outlet syndrome (vTOS) is caused by external compression of the subclavian vein at the costoclavicular junction. It can be subdivided in McCleery Syndrome and Paget-Schroetter Syndrome (PSS). To improve the venous outflow of the arm and to prevent recurrent thrombosis, first rib resection with venolysis of the subclavian vein can be performed. Open transaxillary, supraclavicular, infraclavicular or combined paraclavicular approaches are well known, but more recent robot-assisted techniques are introduced. We report our short- and long-term results of a minimal invasive transthoracic approach for resection of the anteromedial part of the first rib using the DaVinci surgical robot, performed through three trocars. METHODS: We analyzed all patients with vTOS who were scheduled to undergo robot-assisted transthoracic first rib resection in the period July 2012 to May 2016. Outcomes were: technical success, operation time, blood loss, hospital stay, 30-day complications and patency. Functional outcomes were assessed using the "Disability of the Arm, Shoulder and Hand" (DASH) questionnaire. RESULTS: Fifteen patients (8 male, 7 female; mean age 32.9 years, range 20-54 years) underwent robot-assisted transthoracic first rib resection. Conversion to transaxillary resection was necessary in three patients. Average operation time was 147.9 min (range 88-320 min) with a mean blood loss of 79.5 cc (range 10-550 cc). Mean hospital stay was 3.5 days (range 2-9). In three patients, complications were reported (Clavien-Dindo grade 2-3a). Patency was 91% at 15.5 months' follow-up. DASH scores at one and three years showed excellent functional outcomes (7.1 (SD= 6.9, range 0-20.8) and 6.0 (SD= 6.4, range 0-25)) and are comparable to the scores of the normative general population. CONCLUSION: Robot-assisted transthoracic first rib resection with only three trocars is a feasible minimal invasive approach for first rib resection in the management of vTOS. This technique enables the surgeon to perform venolysis under direct 3D vision with good patency and long-term functional outcome. Studies with larger cohort size are needed to compare the outcomes of this robot-assisted technique with other more established approaches.

Our technique of thoracoscopic first rib resection - case report.

INTRODUCTION: First rib resection is a standard surgical treatment for decompressing the neurovascular structures in thoracic outlet syndrome (TOS). Historically, open approaches were used. In this report, we present technical details of thoracoscopic first rib resection. CASE REPORT: This year, we performed two operations in a row using this mini-invasive technique. Three ports were introduced. The used equipment included a laparoscopic camera (30 degree), endoscopic grasper, harmonic scalpel, long neurosurgical bone punch and a long intervertebral disc rongeur. The first rib was cut, separated and removed under thoracoscopic control. CONCLUSION: Thoracoscopic first rib resection for TOS is a safe and promising technique.

Rib-sparing scalenectomy for neurogenic thoracic outlet syndrome: Early results.

OBJECTIVE: Neurogenic thoracic outlet syndrome (NTOS) is no longer either "controversial" or "disputed"; however, its optimal surgical management remains unclear. Many thoracic outlet decompression procedures are performed by first rib resection, usually via a transaxillary route. METHODS: A retrospective review of a prospectively maintained NTOS database was performed. Patients with NTOS associated with a cervical rib and those with recurrent NTOS were excluded from the present analysis. All study patients had satisfied a 5-point clinical diagnostic protocol and had experienced a positive response to a local anesthetic scalene block. Surgical decompression included anterior, minimus, and middle scalenectomy and brachial plexus neurolysis via a supraclavicular incision and pectoralis minor tenotomy through a small vertical infraclavicular incision. No first ribs were excised. All the patients had completed QuickDASH (11-item version of the Disability of the Arm, Shoulder, and Hand questionnaire) preoperatively and at 3 or 6 months postoperatively. RESULTS: From 2011 to 2019, 504 thoracic outlet decompression procedures had been performed in 442 patients. The average operative time was 1.15 hours, and the average hospital length of stay was 1.05 days. Major complications, including intraoperative arterial injury, postoperative wound hematoma requiring reoperation, and chylothorax, occurred in 7 patients (1.4%). All but 2 patients (99.6%) had symptomatic improvement. Using a more rigorous definition of operative success of ≥50% improvement in the 3- or 6-month QuickDASH score, 458 rib-sparing NTOS operations (90.9%) were successful. In contrast to the mean preoperative QuickDASH score of 62.6, the average postoperative QuickDASH score was 25.2 (P = .001). CONCLUSIONS: These results suggest that (1) adherence to a rigorous preoperative diagnostic regimen, including performance of a scalene block, ensures, at the least, that surgery for NTOS can be successfully restricted to patients actually with the condition; (2) fibrotic, contracted scalene muscles are the cause of NTOS; (3) the first rib does not require removal for successful surgical treatment of NTOS; and (4) 90% of the patients so treated can expect significant early symptomatic and functional improvement.

Specialty Mediated 30-Day Complications in First Rib Resection for Thoracic Outlet Syndrome.

BACKGROUND: Thoracic outlet syndrome (TOS) takes on heterogenous upper extremity manifestations depending on whether the artery, vein or brachial plexus is primarily compressed. As a result of these variable vascular and neurogenic symptoms, these patients present to surgeons of various training backgrounds for surgical decompression. Surgeon specialty is known to correlate with outcomes for numerous vascular procedures, but its role in TOS is unclear. In this work we examine the association of surgeon specialty with short-term outcomes following first rib resection (FRRS) for TOS. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database, 3,070 patients were identified who underwent FRRS for TOS between 2006-2017. The primary outcomes of the study were 30-d complications, including postoperative hemorrhage requiring transfusion, wound complications, pneumothorax and deep venous thrombosis. Arterial, venous, and neurogenic TOS were distinguished with ICD-9 and 10 codes while patient characteristics, provider specialty, and postoperative outcomes were classified through a combination of standard National Surgical Quality Improvement Program variables and ICD data. RESULTS: Most FRRS were performed by vascular surgeons (87.9%), general (6.9%) and thoracic surgeons (4.4%). The relative distribution of vascular TOS between the specialties was not significantly different, with non-vascular surgeons performing an equivalent amount of FRRS for arterial (1.1% versus 2.4%) and venous TOS (8.6% versus 9.1%, both P> 0.05). Patients who underwent FRRS with non-vascular surgeons experienced more frequent perioperative transfusions (3.2% versus 1.2%, P = 0.001) and wound infections (1.9% versus 0.8%, P= 0.04). On multivariable regression, patients undergoing FRRS for venous TOS were more likely to require blood transfusion (odds ratios:3.63, 95% CI 1.43-9.25). Patients operated on by surgeons whose specialty was not among the top three most common specialties performing FRRS had a 40% longer operative time (incidence rate ratios:1.42, 95% CI 1.15-1.74) as well as a significantly increased odds of requiring a transfusion (odds ratios:9.87, 95% CI 2.28-42.68). CONCLUSIONS: The significantly increased operative times and transfusion requirements associated with specialties who uncommonly perform FRRS suggest the role of surgeon experience and volume in this procedure may play more of a role than specialty training. These data also suggest that vascular TOS carries unique risks that should be kept in mind when performing FRRS.

Outcomes following operative management of thoracic outlet syndrome in the pediatric patients.

Objectives Thoracic outlet syndrome, a condition commonly reported in adults, occurs infrequently in the pediatric population. The objective of this study was to assess the outcome of surgical interventions of thoracic outlet syndrome in pediatric patients. Methods Clinical records of all pediatric patients with thoracic outlet syndrome who underwent operative repair from 2002 to 2015 in a tertiary pediatric hospital were reviewed. Pertinent clinical variables and treatment outcomes were analyzed. Results Sixty-eight patients underwent a total of 72 thoracic outlet syndrome operations (mean age 15.7 years). Venous, neurogenic, and arterial thoracic outlet syndromes occurred in 39 (57%), 21 (31%), and 8 (12%) patients, respectively. Common risk factors for children with venous thoracic outlet syndrome included sports-related injuries (40%) and hypercoagulable disorders (33%). Thirty-five patients (90%) with venous thoracic outlet syndrome underwent catheter-based interventions followed by surgical decompression. All patients underwent first rib resection with scalenectomy via either a supraclavicular approach (n = 60, 88%) or combined supraclavicular and infraclavicular incisions (n = 8, 12%). Concomitant temporary arteriovenous fistula creation was performed in 14 patients (36%). Three patients with arterial thoracic outlet syndrome underwent first rib resection with concomitant subclavian artery aneurysm repair. The mean follow-up duration was 38.4 ± 11.6 months. Long-term symptomatic relief was achieved in 94% of patients. Conclusions Venous thoracic outlet syndrome is the most common form of thoracic outlet syndrome in children, followed by neurogenic and arterial thoracic outlet syndromes. Competitive sports-related injuries remain the most common risk factor for venous and neurogenic thoracic outlet syndromes. Temporary arteriovenous fistula creation was useful in venous thoracic outlet syndrome patients in selective children. Surgical decompression provides durable treatment success in children with all subtypes of thoracic outlet syndrome.

Infantile cranial fasciitis: case-based review and operative technique.

BACKGROUND: Cranial fasciitis (CF) is an uncommon benign primary lesion of the skull that typically affects the pediatric age group. Due to the rarity of CF, no prospective studies exist. Earliest description of this condition dates to 1980. The limited scientific and clinical literature regarding CF is dominated by case reports. For these reasons, questions pertaining to the true incidence, genetic risk factors, prognosis, and long-term outcome remain unanswered. DISCUSSION: Clinically, CF presents as a firm, painless, growing scalp mass that is typically not considered in the differential diagnosis. Preoperative pathognomonic signs and symptoms are absent, and imaging features are often nonspecific. Treatment is typically through complete surgical resection, at which time histopathological examination confirms the diagnosis of CF. Reconstruction of the skull defect in the child is critical. Autograft techniques help maintain a rigid construct that integrates with the native skull while preserving its continued ability to grow. Generally, a good outcome is observed with complete resection. EXEMPLARY CASE: We report a case of CF in an infant with emphasis on operative nuances and early follow-up results. CONCLUSION: CF is a rare fibroproliferative disease that has a poorly defined incidence and long-term follow-up. Due to its locally invasive nature and nonspecific presentation, CF is often difficult to differentiate from malignancies and infections. Complete surgical resection is the best approach for diagnosis and cure. Its occult clinical presentation often allows it to achieve considerable growth, leaving a sizeable skull defect following resection. Since CF presents in the pediatric population, allograft reconstruction is preferred over titanium mesh or other synthetic materials to allow osseous integration and continued uninterrupted skull growth.

Thoracic outlet syndrome: single-center experience on the transaxillary approach with the aid of the TRIMANO Arthrex arm.

Thoracic outlet syndrome (TOS) is a pathology caused by compression on the neurovascular bundle by the first rib. The treatment of TOS is conservative management by analgesia and physiotherapy; however, if there is no response to conservative treatment, surgery is indicated through thoracic outlet decompression by first rib resection. Several surgical techniques are available, including supraclavicular, transaxillary, and transthoracic first rib resection approaches. The transaxillary approach provides better visualization on the neurovascular bundle and, thus, is sometimes the preferred method of treatment. The transaxillary approach has been criticized due to safety concerns regarding the neural bundle during surgical exposure. During surgery, hyperabduction of the arm is obtained by a surgical assistant, and the quality of exposure can decrease with time, or an iatrogenic injury to the neural bundle (brachial plexus) can occur from the hyperabduction. The use of the TRIMANO Arthrex arm can help in the exposure, instead of a surgical aide, because it provides stable exposure and visualization for the operating surgeon. We performed a retrospective review of patients undergoing transaxillary first rib resection using the TRIMANO Arthrex arm between June 2021 and December 2022. During installation, the patient is placed in the lateral decubitus position and the TRIMANO Arthrex arm is fixed at the operating table at the height of the patient's shoulder. Thus, the surgical aide can help the surgeon during the surgery, rather than placing the arm into and out of hyperabduction. The use of hyperabduction is limited to 15 minutes, followed by 5 minutes of rest, to decrease the tension on the neurovascular bundle. The surgeon then performs the transaxillary approach and systematically resects the first rib, scalene muscles, and subclavian muscles. By this approach, the inferior brachial plexus is also lysed. In our review, we found a total of 15 procedures of first rib resection for the treatment of TOS with the aid of the TRIMANO Arthrex arm that met our inclusion criteria. All procedures were performed by the same surgeon. None of the patients sustained an injury to the neurovascular bundle. All the patients had an uneventful hospital stay postoperatively, and none presented with a hematoma. The drain placed during surgery was removed on postoperative day 2. All patients had at least one radiograph taken during their hospitalization, with no pleural effusion or pneumothorax found. The use of the TRIMANO Arthrex arm is safe and can help in the positioning and installation of the patients undergoing transaxillary first rib resection. It decreases the number of surgical assistants and offers great comfort for the surgeon because it provides stable exposure for the operating surgeon.

Video-assisted thoracic surgery and robotic-assisted first-rib excision and thoracic outlet syndrome decompression.

Multiple surgical approaches have been used in the management of thoracic outlet syndrome. These approaches have traditionally been "open" approaches and have been associated with the inherent morbidities of an open approach, including a risk of injury to the neurovascular structures due to traction and trauma while resecting the first rib. In addition, there has been concern that recurrence of symptoms may be related to incomplete resection of the rib with conventional open techniques. With the advent of minimally invasive thoracic surgery, surgeons began to explore first-rib resection via a thoracoscopic approach. Unfortunately, the existing video-assisted thoracic surgery technology and equipment was not well suited to working in the apex of the chest. With the introduction and subsequent progress in robotic surgery and instrumentation, this dissection can be performed with all the advantages of robotics, but also with minimal traction and trauma to the neurovascular structures, and incorporates almost complete resection of the rib with minimal residual stump. Robotics has developed as a reliable, safe, and less invasive approach to first-rib resection, yielding excellent results while limiting the morbidity of the procedure.

The effect of 11th rib excision on perioperative outcomes in patients undergoing partial nephrectomy for upper pole renal tumors.

INTRODUCTION: We aimed to evaluate the effect of eleven11th rib resection.on the perioperative period TRIFECTA criteria in patients who underwent retroperitoneal partial nephrectomy (PN) with the diagnosis of upper pole kidney tumors. MATERIALS AND METHODS: We conducted a retrospective analysis of the data of the patients who underwent Open PN for upper pole renal masses between 2018 and 2023. The patients were divided into two groups: PN with rib resection and PN without rib resection. The demographic characteristics, tumor sizes, PADUA scores, warm-cold renal ischemia times, mass excision and tumor bed suturing times, histopathological tumor type and surgical margin positivity of the patients were examined. Both groups were evaluated comparatively based on this data. RESULTS: The renal nephrometry scores of the two groups were similar. The total renal ischemia time was significantly shorter in the patients who underwent a rib resection than in those who did not (p < 0.001). Both the tumor excision and tumor bed suturing times were significantly shorter in the group that underwent a rib resection than in the group that did not (p < 0.001). The Clavien-Dindo complication grades were statistically similar between the two groups. CONCLUSION: Complex in nature and high-risk renal masses located in the upper pole of the kidney, partial nephrectomy performed with an 11th rib resection can be considered a reliable surgical option with a shorter ischemia time, supporting the preservation of long-term renal function.

Endoscopically assisted transaxillary release of the scalene muscles for thoracic outlet syndromes: a comparison with or without first rib resection.

OBJECTIVES: There are several surgical techniques for thoracic outlet syndrome (TOS). However, there have been no reports of endoscopically assisted transaxillary release of the anterior and middle scalene muscles (EATRS), leaving the first rib intact for TOS. We hypothesized that EATRS would achieve a good Quick Disability of the Arm, Shoulder and Hand score. This study aims to present our experience with a new technique for TOS using endoscopy. METHODS: We chose two surgeries depending on the patient's TOS condition. If the costoclavicular space was under 12 mm, we selected endoscopically assisted transaxillary first rib resection (EAFRR). If the costoclavicular space was over 12 mm, we selected EATRS. Between January 2021 and December 2022, 31 consecutive surgeries for TOS were performed in our institution. Twenty-five patients underwent EAFRR, and six (19%) underwent EATRS. Since July 2022, EAFRR has been performed under differential lung ventilation. RESULTS: Complete and almost complete relief was achieved in 24 patients (77%), and partial relief was conducted in seven patients (23%) at a mean of 19.7 months after surgery. The symptoms improved in all cases. Intraoperative pneumothorax did not occur, and no other complications were observed. Both EAFRR and EATRS were effective and safe surgeries for TOS. Operative time was significantly shorter in EATRS than in EAFRR. CONCLUSIONS: We first report EATRS surgery for TOS. EATRS is indicated for patients whose costoclavicular space is preserved before surgery. Good surgical results were obtained after surgery for this indication.

17 years' experience of surgical management of thoracic outlet syndrome at a district general hospital.

INTRODUCTION: Thoracic outlet syndrome (TOS) is caused by compression of the neurovascular structures passing through the thoracic inlet. It is categorised into three subtypes: neurogenic TOS (NTOS), venous TOS (VTOS) and arterial TOS (ATOS). This study evaluates the outcomes of patients who underwent first rib resection (FRR) for TOS during a period of 17 years at a single district general hospital. METHODS: Retrospective review of patient notes of individuals treated with FRR from August 2004 to August 2021. RESULTS: A total of 62 FRRs were performed on 51 individual patients. Indications for FRR included 42 NTOS (68%), 6 VTOS (10%) and 14 ATOS (23%). Thirty-four patients (64%) were female and the mean age at time of surgery was 39 years (range 27 to 64 years). Eleven patients (21%) underwent bilateral FRR and seven cases of cervical ribs were observed. The mean time from initial symptoms to diagnosis was 18 months (range 2 to 60 months). Overall, outcomes after surgery were positive across all subtypes of TOS. Based on Derkash's classification, 52 patients (84%) reported excellent/good, 8 (13%) reported fair and 2 (3%) reported poor resolution of symptoms at 6 month follow-up. Complications included four (9%) pneumothorax, two (4%) wound infections, two (4%) haematoma, one (2%) haemothorax, three (5%) phrenic nerve complications and one (2%) brachial neuropraxia. CONCLUSIONS: FRR for TOS can be performed safely and effectively in a district general hospital environment with excellent patient clinical outcomes.

Videothoracoscopic First Rib Resection for Neurogenic Thoracic Outlet Syndrome: Results of 13 Patients.

PURPOSE: To present the clinical experience in video-assisted thoracic surgery (VATS) of first rib resection for patients with neurogenic thoracic outlet syndrome (NTOS). METHODS: The files of 13 patients (10 males, 3 females) having unilateral NTOS undergoing first rib resection via VATS were retrospectively investigated. The symptoms, operative times, durations of chest tube and hospital stay, complications, and postoperative courses were analyzed. All patients underwent VATS using a camera port and 3-5 cm utility incision. RESULTS: There was no morbidity. The average operation time was 81 ± 11 min (range 65-100 min). Chest tubes were removed in the first or second postoperative day (mean 1.23 ± 0.43 days). The mean postoperative length of hospital stay was 2.1 ± 0.9 days (range 1-3 days). The average duration of follow-up was 19 ± 13 months (range 2-38 months). Ten patients completed a follow-up during 6 months. One patient (10%) had minor residual symptoms, and the remaining patients (90%) were fully asymptomatic. CONCLUSION: The VATS approach in the resection of the first rib for thoracic outlet syndrome is a safe method. It should be performed with acceptable risks under experienced hands. The magnified view and optimal visualization from the scope are beneficial. Avoiding neurovascular bundle retraction may seem to decrease the postoperative pain.
