Thoracic outlet syndrome in paediatrics: clinical presentation, surgical treatment, and outcome in a series of eight children

The impact of competitive level of high school and collegiate athletes on outcomes of thoracic outlet syndrome

OBJECTIVE

Thoracic outlet syndrome (TOS) has life-changing impacts on young athletes. As the level of competition increases between the high school (HS) and collegiate (CO) stage of athletics, the impact of TOS may differ. Our objective is to compare surgical outcomes of TOS in HS and CO athletes.

METHODS

This was a retrospective review of HS and CO athletes within a prospective surgical TOS database. The primary outcome was postoperative return to sport. Secondary outcomes were resolution of symptoms assessed with somatic pain scale (SPS), QuickDASH, and Derkash scores. Categorical and continuous variables were compared using χ2 and analysis of variance, respectively. Significance was defined as P < .05.

RESULTS

Thirty-two HS and 52 CO athletes were identified. Females comprised 82.9% HS and 61.5% CO athletes (P = .08). Primary diagnoses were similar between groups (venous TOS: HS 50.0% vs CO 42.3%; neurogenic TOS: 43.9% vs 57.7%; pectoralis minor syndrome: 6.3% vs 0.0%) (P = .12). Pectoralis minor syndrome was a secondary diagnosis in 3.1% and 3.8% of HS and CO athletes, respectively (P = 1.00). The most common sports were those with overhead motion, specifically baseball/softball (39.3%), volleyball (12.4%), and water polo (10.1%), and did not differ between groups (P = .145). Distribution of TOS operations were similar in HS and CO (First rib resection: 94.3% vs 98.1%; scalenectomy: 0.0% vs 1.9%, pectoralis minor tenotomy: 6.3% vs 0.0%) (P = .15). Operating room time was 90.0 vs 105.3 minutes for HS and CO athletes, respectively (P = .14). Mean length of stay was 2.0 vs 1.9 days for HS and CO athletes (P = .91). Mean follow-up was 6.9 months for HS athletes and 10.5 months for CO athletes (P = .39). The majority of patients experienced symptom resolution (HS 80.0% vs CO 77.8%; P = 1.00), as well as improvement in SPS, QuickDASH, and Derkash scores. Return to sport was similar between HS and CO athletes (72.4% vs 73.3%; P = .93). Medical disability was reported in 100% HS athletes and 58.3% CO athletes who did not return to sport (P = .035).

CONCLUSIONS

Despite increased level of competition, HS and CO athletes demonstrate similar rates of symptom resolution and return to competition. Of those that did not return to their sport, HS athletes reported higher rates of medical disability as a reason for not returning to sport compared with CO athletes.

Adolescent athletes can get back in the game after surgery for thoracic outlet syndrome

OBJECTIVE

We compared the functional outcomes among adolescent athletes with venous thoracic outlet syndrome (VTOS) and neurogenic TOS (NTOS) after thoracic outlet decompression.

METHODS

We performed a single-institution retrospective review of a prospective database of adolescent athletes (aged 13-19 years) from June 1, 1996 to December 31, 2021 who had undergone operative decompression for TOS. The demographic data, preoperative symptoms, operative details, and postoperative outcomes were compared. The primary outcome was the postoperative return to sport. The secondary outcomes included symptom resolution and assessment of the somatic pain scale, QuickDASH, and Derkash scores. The Fisher exact test and t test were used to evaluate the categorical and continuous variables, respectively. A logistic regression model was constructed to adjust for the influence of preoperative factors and return to sport.

RESULTS

A total of 60 patients (40.0% with VTOS and 60.0% with NTOS) were included. The average age of the VTOS patients was 17.2 years vs 16.6 years for the NTOS patients (P = .265). The NTOS patients were more likely to be female (88.9% vs 62.5%; P = .024). The NTOS patients had more frequently presented with pain (97.2% vs 70.8%; P = .005), paresthesia (94.4% vs 29.1%; P = .021), and weakness (67.7% vs 12.5%; P = .004) but had less often reported swelling (25.0% vs 95.8%; P < .001). At presentation, the NTOS patients had also reported a longer symptom duration (17.7 months vs 3.1 months; P < .001). Transaxillary first rib resection with subtotal scalenectomy was performed for 100% of the VTOS patients and 94.4% of the NTOS patients undergoing cervical rib resection (2.8%) or scalenectomy alone (2.8%). Additionally, 11.1% of the NTOS patients had undergone combined first rib resection and cervical rib resection. For the VTOS patients, postoperative venography showed patent subclavian veins in 27.8%. In addition, 44.4% had required venoplasty, 16.8% had required thrombolysis, and 11% were chronically occluded. No significant differences were found in blood loss, operative time, or length of stay between the groups. No surgical complications occurred. The average follow-up was 6.3 months. Significant differences were found between the VTOS and NTOS groups for the pre- and postoperative somatic pain scale, QuickDASH, and Derkash scores. Complete symptom resolution had occurred in 83.3% of the VTOS and 75% of the NTOS patients (P = .074). No statistically significant difference in the return to sport was observed between the two groups (VTOS, 94.4%; vs NTOS, 73.9%; P = .123). Of the NTOS patients, 10.0% had had other concomitant injuries and 5.0% had had medical conditions that had precluded their return to sport. Logistic regression found no significant relationship between the preoperative somatic pain scale score, QuickDASH score, or duration of symptoms and the return to sport.

CONCLUSIONS

Adolescent athletes with VTOS and NTOS can have good functional outcomes, and most will be able to return to sport after surgery. Greater initial symptom severity and concomitant injuries were observed in adolescents with NTOS. Of those who had not returned to sport postoperatively, three of seven had had unrelated health issues that had prevented their return to sport.

Venous thoracic outlet syndrome and Paget-Schroetter syndrome

Venous thoracic outlet syndrome represents a relatively rare but important diagnosis in the adolescent population with increasing recognition. Compression of the subclavian vein within the costoclavicular space can lead to episodic venous outlet obstruction in the upper extremity, with edema, rubor and functional symptoms. Over time, cumulative injury and compression can lead to thrombosis of the vein, referred to as "effort thrombosis" or the Paget-Schroetter syndrome. This progression can lead to the need for acute management of the venous thromboembolism, requirement for thoracic outlet decompression surgery and the potential for long-term sequelae such as post-thrombotic syndrome. Management is focused on clot minimization, anticoagulation during the period of endothelial injury and inflammation and surgical decompression via first rib resection, anterior scalenectomy and venolysis to remove external compression of the vein. This manuscript reviews the diagnosis, evaluation and treatment of venous thoracic outlet syndrome and Paget-Schroetter syndrome.

Cervical ribs in human early life: morphological variability and first identification as a morbidity criterion in a past population

Despite the medical literature on supernumerary cervical ribs in extant adult samples, little is known about their development and occurrence in early infancy. The documentation of cervical ribs in modern samples of fetuses and neonates is indeed affected by ethical as well as technical limitations. The aim of the present study was to investigate their frequencies and morphological variability in the first known archaeological collection of very young children with this anatomical variant. The study sample comes from the 8B-51 necropolis on the Saï island (Sudan) and dates to the Classic Kerma Period (XVIIIe-XVIe centuries BC). It consists of 64 individuals deceased between 24 weeks of amenorrhoea and 2 years of age. Bilateral or unilateral cervical ribs were found in 27 individuals. A total of 43 cervical ribs were identified, 38 of which are fully preserved. According to these observations, at least 42% of the individuals have unilateral or bilateral cervical ribs, with an average maximum length of < 1 cm. This frequency is very high compared to those observed in contemporary adult samples (up to 3%). First, the comparison of our results with biological and genetic research demonstrating the link between the occurrence of cervical ribs and a reduced chance of survival during infancy allows the first identification of this trait as an indicator of morbidity in an archaeological collection, a morbidity to which a genetic homogeneity or even endogamy could contribute. Second, the number of ribs studied makes it possible to propose a morphological classification based on the general shape and the shape of the articular facets, classification that can be used tos refine the analyses of the trait in future samples.

Treatment-Related Outcomes in Paget-Schroetter Syndrome-A Cross-Sectional Investigation

OBJECTIVE

To investigate treatment-related outcomes, namely radiological clot resolution, post-thrombotic syndrome (PTS), and health related quality-of-life (HRQoL) scores, in children with Paget-Schroetter syndrome (PSS) undergoing multidisciplinary management, including anticoagulation and decompressive rib-resection surgery, with or without thrombolytic therapy.

STUDY DESIGN

We identified all patients treated for PSS at our institution between the years 2010 and 2017. Baseline clinical and radiologic data were abstracted from medical records. Two validated survey instruments to quantify PTS and HRQoL were mailed to eligible patients. Standard statistical methods were used to summarize these measures.

RESULTS

In total, 22 eligible patients were identified; 10 were treated with thrombolysis followed by anticoagulation and rib resection, and 12 were treated with anticoagulation and rib resection alone. Nineteen patients responded to the survey instruments. Median age at deep vein thrombosis diagnosis and survey completion were 16.3 and 20.4 years, respectively. Nineteen of 22 patients had thrombus resolution on radiologic follow-up. Fourteen of 19 survey respondents reported signs/symptoms of PTS of which the majority (12/14) reported mild PTS. Aggregate total, physical, and psychosocial HRQoL scores reported were 90.6, 96.7, and 93.3, respectively. Thrombolytic therapy was not associated with a significant improvement in radiologic, clinical or HRQoL outcomes.

CONCLUSIONS

Most patients with PSS had complete thrombus resolution on imaging. Only 11% of survey respondents reported moderate PTS. The entire cohort reported excellent HRQoL scores. The role for thrombolytic therapy in the management of childhood PSS remains incompletely elucidated.

Peripheral nerve injuries in the pediatric population: a review of the literature. Part II: entrapment neuropathies

INTRODUCTION

Entrapment neuropathies are infrequent in children, and therefore remain unrecognized. The incidence of radial, median, and cubital mononeuropathies are all similar. Despite the rarity of such cases, extensive, albeit scattered, literature has accumulated concerning entrapment neuropathies in children.

OBJECTIVE

To the literature concerning entrapment neuropathies in children.

METHODS

A systematic review of the existing literature has been made.

RESULTS

The management of chronic pediatric pain is very important in such patients to prevent youths from experiencing prolonged absences from school, sports, or other productive activities, and limit the psychological burden of chronic disease. Nonsurgical treatment of both cubital and carpal tunnel syndromes has been disappointing in pediatric patients, with only limited success; and, to date, there is no clear explanation for the outcome differences generated by nonsurgical management between adults and youths. Simple decompression of the ulnar nerve at the elbow also has much higher rates of failure in children than in adults.

CONCLUSIONS

The presence of an entrapment neuropathy (specially carpal tunnel syndrome) in a pediatric-age patient should alert medical care providers to the potential of some underlying genetic condition or syndrome.

Long-term outcomes after surgical treatment of pediatric neurogenic thoracic outlet syndrome

OBJECTIVE Neurogenic thoracic outlet syndrome (nTOS) is an uncommon compression syndrome of the brachial plexus that presents with pain, sensory changes, and motor weakness in the affected limb. The authors reviewed the clinical presentations and outcomes in their series of pediatric patients with surgically treated nTOS over a 6-year period. METHODS Cases of nTOS in patients age 18 years or younger were extracted for analysis from a prospective database of peripheral nerve operations. Baseline patient characteristics, imaging and neurophysiological data, operative findings, and outcomes and complications were assessed. RESULTS Twelve patients with 14 cases of nTOS surgically treated between April 2010 and December 2016 were identified. One-third of the patients were male, and 2 male patients underwent staged, bilateral procedures. Disabling pain (both local and radiating) was the most common presenting symptom (100%), followed by numbness (35.7%), then tingling (28.6%). The mean duration of symptoms prior to surgery was 15.8 ± 6.6 months (mean ± SD). Sports-related onset of symptoms was seen in 78.6% of cases. Imaging revealed cervical ribs in 4 cases, prominent C-7 transverse processes in 4 cases, abnormal first thoracic ribs in 2 cases, and absence of bony anomalies in 4 cases. Neurophysiological testing results were normal in 85.7% of cases. Conservative management failed in all patients, with 5 patients reporting minimal improvement in symptoms with physical therapy. With a mean follow-up after surgery of 22 ± 18.3 months (mean ± SD), pain relief was excellent (> 90%) in 8 cases (57.1%), and good (improved > 50%) in 6 cases (42.9%). On univariate analysis, patients who reported excellent pain resolution following surgery at long-term follow-up were found to be significantly younger, and to have suffered a shorter duration of preoperative symptoms than patients who had worse outcomes. Lack of significant trauma or previous surgery to the affected arm was also associated with excellent outcomes. There were 4 minor complications in 3 patients within 30 days of surgery: 1 patient developed a small pneumothorax that resolved spontaneously; 1 patient suffered a transient increase in pain requiring consultation, followed by hiccups for a period of 3 hours that resolved spontaneously; and 1 patient fell at home, with transient increased pain in the surgically treated extremity. There were no new neurological deficits, wound infections, deep vein thromboses, or readmissions. CONCLUSION Pediatric nTOS commonly presents with disabling pain and is more frequently associated with bony anomalies compared with adult nTOS. In carefully selected patients, surgical decompression of the brachial plexus results in excellent pain relief, which is more likely to be seen in younger patients who present for early surgical evaluation.

How We Manage Pediatric Deep Venous Thrombosis

Over the past two decades, the incidence and recognition of venous thromboembolism (VTE) in children has significantly increased, likely as a result of improvements in the medical care of critically ill patients and increased awareness of thrombotic complications among medical providers. Current recommendations for the management of VTE in children are largely based on data from pediatric registries and observational studies, or extrapolated from adult data. The scarcity of high-quality evidence-based recommendations has resulted in marked variations in the management of pediatric VTE among providers. The purpose of this article is to summarize our institutional approach for the management of VTE in children based on available evidence, guidelines, and clinical practice considerations. Therapeutic strategies reviewed in this article include the use of conventional anticoagulants, parenteral targeted anticoagulants, new direct oral anticoagulants, thrombolysis, and mechanical approaches for the management of pediatric VTE.

Paget-Schroetter syndrome in 21 children: outcomes after multidisciplinary care

OBJECTIVE

To review the presentation, management, and outcomes of Paget-Schroetter syndrome (PSS) in children and propose a multidisciplinary treatment algorithm involving pediatric and vascular surgery, interventional radiology, and hematology.

STUDY DESIGN

Patients with PSS presenting between 2003 and 2013 were reviewed. Demographics, symptoms, therapies, and functional outcomes were noted. Data from early patients informed the development of a multidisciplinary treatment algorithm applied to later patients.

RESULTS

Of 21 patients, mean ± SD age was 16 ± 1.6 years and 11 (52%) were male. Of patients with complete presentation data, common symptoms were edema (84%), discoloration (58%), and pain (58%). Thrombophilia workup revealed one heterozygote for factor V Leiden, 2 patients with factor VIII elevation and 1 patient with mildly low antithrombin. The most recent 8 patients were treated according to an algorithm developed by a multidisciplinary working group through experience with the first 13 cases. All patients underwent a venogram, endovascular intervention (including 15 receiving catheter-directed thrombolysis), and operative ipsilateral thoracic outlet decompression (first rib resection, anterior scalenectomy, and venolysis). Postoperative complications included hemothorax (2), pneumothorax (1), and recurrent thrombosis (2). Follow up duration was 12 ± 9.5 months. Symptoms recurred transiently in 1 patient.

CONCLUSION

Pediatric patients with PSS can be treated successfully using a multidisciplinary treatment algorithm including anticoagulation, catheter-directed thrombolysis, and operative decompression of the thoracic outlet. Early outcomes are promising.

Managing pediatric thoracic outlet syndrome

Background

Thoracic outlet syndrome (TOS) is largely overlooked in children and adolescents because the condition is not widely viewed as a pediatric disorder. This study aimed to clarify the causes, best treatment approaches, and prognosis for young patients with TOS.

Methods

A retrospective study was conducted on 13 patients, from 4 to 13 years of age, with TOS. Ten children underwent surgical treatment, and three were treated conservatively. All patients received local nerve blocks on two occasions and were followed-up for more than 2 years.

Results

Among the 10 children who underwent surgery, six school-aged children returned to school 10 to 14 days after surgery. Parents of the three children treated conservatively reported that activity within the affected limb and overall muscle strength had increased in their children and none of the three children had complained about discomfort in the affected limb.

Conclusion

A diagnosis of TOS should be considered when a child or adolescent has neck and shoulder discomfort, hand numbness, and upper limb weakness. As with adults with TOS, detailed physical examination is the key to diagnosing pediatric TOS. Conservative treatment is effective for young TOS patients who have mild changes in the length and thickness of the affected limb and is an option when parents refuse surgical treatment.

Thoracic outlet syndrome in the pediatric population: case series

We present 4 patients, 4 months to 10 years of age, with thoracic outlet syndrome. All were referred to the brachial plexus clinic. Three patients were diagnosed with vascular thoracic outlet syndrome after clinical evaluation and diagnostic imaging. Three had a cervical rib and 1 had an anomalous first rib. All patients were treated surgically through a supraclavicular approach and had resolution of the symptoms. No postoperative complications were noted.

Supraclavicular decompression for neurogenic thoracic outlet syndrome in adolescent and adult populations

OBJECTIVE

This study was conducted to better define clinical results and understand factors determining responsiveness to surgical treatment for neurogenic thoracic outlet syndrome (NTOS) in adolescent and adult populations.

METHODS

A retrospective review was conducted for 189 patients with disabling NTOS who underwent primary supraclavicular decompression (scalenectomy, brachial plexus neurolysis and first rib resection, with or without pectoralis minor tenotomy) from April 2008 to December 2010. Clinical characteristics were compared between 35 adolescent patients (aged<21 years) and 154 adults (aged>21 years). Functional outcome measures were assessed before surgery and at 3- and 6-month follow-up using a composite NTOS Index combining the Disabilities of the Arm, Shoulder and Hand (DASH) survey, the Cervical-Brachial Symptom Questionnaire (CBSQ), and a 10-point visual analog scale (VAS) for pain.

RESULTS

Adolescent and adult patients were not significantly different with respect to sex (overall 72.5% female), side affected (58.7% right, 60.3% dominant limb), bony anomalies (23.3%), previous injury (55.6%), coexisting pain disorders (11.1%), and positive responses to scalene muscle anesthetic blocks (95.6%). Compared with adults, adolescent patients had a significantly (P<.05) lower incidence of depression (11.4% vs 41.6%), motor vehicle injury (5.7% vs 20.1%), previous operations (11.4% vs 29.9%), preoperative use of opiate medications (17.1% vs 44.8%), and symptom duration>2 years (24.2% vs 50.0%). Mean preoperative NTOS Index (scale 0-100) was significantly lower in adolescent vs adult patients (46.5±3.6 vs 58.5±1.7; P=.009), and hospital length of stay was 4.4±0.2 vs 4.9±0.1 days (P=.03), but the rate of postoperative complications was no different (overall, 4.2%). Although both groups exhibited significant improvement in functional outcome measures at 3 and 6 months, adolescent patients had significantly lower NTOS Index (10.4±3.1 vs 39.3±3.3; P<.001) and use of opiate medications (11.4% vs 47.4%; P<.001) compared with adults.

CONCLUSIONS

Adolescents undergoing supraclavicular decompression for NTOS had more favorable preoperative characteristics and enhanced 3-month and 6-month functional outcomes than adults. Further study is needed to delineate the age-dependent and independent factors that promote optimal surgical outcomes for NTOS.

Anomalies of thoracic outlet in human fetuses: anatomical study

BACKGROUND

Thoracic outlet syndrome (TOS) identifies the clinical condition determined by the mechanical compression and entrapment of the subclavian vessels and the brachial plexus cords within the space delineated by the scalene muscles, the clavicle, and the first rib. To date, there are no concluding explanations concerning the real causes of the appearance of TOS in children. This is the first study to investigate the existence, frequency, and type of thoracic outlet anomalies in the prenatal stage (human fetuses).

METHODS

Eighty cervical dissections (40 consecutive spontaneously aborted human fetuses) were performed, and the musculoskeletal, vascular, and nervous elements that pass through the thoraco-cervico-axillary region were investigated.

RESULTS

Overall, anatomical anomalies of the thoraco-cervico-axillary region were found in 60% of the 80 cervical dissections. Nine (22.5%) of the 40 fetuses had normal bilateral anatomy. In 6.3%, the scalene hiatus had an oval shape due to the common costal insertion of the anterior and middle scalene muscles. Fibromuscular bands were found in 15% of the fetuses. Hypertrophy of the anterior scalene muscle was seen in 12.5% of the dissections. In 28.7% of the cervical dissections, hypertrophy of the C7 transversal process was noted, bilateral in seven cases. There was one case of a "C-shaped" clavicle anomaly. The absence of the internal mammary artery was noted in one case.

CONCLUSION

This study shows that the presence of TOS anomalies in fetuses is not a rare occurrence, emphasizing a pathological cervical background which can be harmful in situations of cervical trauma or inflammatory processes. Having knowledge of the types of anomalies which can lead to TOS is important for performing a complete surgical correction and avoiding the high failure rate of recurrent TOS.

Thoracic outlet syndrome in children and young adults

OBJECTIVES

Thoracic outlet syndrome has been well described in the population between 25 and 40 years of age, and is less frequently reported in those in the first two decades of life. The objective of this study was to review results with onset of TOS in the first two decades of life to determine type of presentation and outcomes from surgical intervention.

METHODS AND MATERIALS

Charts of all patients in the first two decades of life, operated on for TOS between 1994 and 2006 were reviewed with follow-up by clinic visit and phone survey to assess the patients' current level of activity and relief from symptoms.

RESULTS

Twelve patients were identified (13 operations), with a mean age of 16.8 years. Acute ischemic symptoms were the initial presentation for 38%, venous TOS in 24%, and neurogenic symptoms in 38%. All patients had symptom relief with surgery with a mean time to resolution of 10.9 weeks. All patients remained symptom free or improved at follow-up.

CONCLUSIONS

Vascular TOS is much more common in TOS presenting in the first two decades of life. Surgical intervention for TOS in this population results in long-lasting symptom relief and should be considered for all subtypes of patients.

Pediatric thoracic outlet syndrome: a disorder with serious vascular complications

BACKGROUND

Thoracic outlet syndrome (TOS), caused by compression of the neurovascular structures between the clavicle and scalene muscles, typically presents with neurologic symptoms in adults. We reviewed our experience with 25 adolescents and propose a diagnostic/treatment algorithm for pediatric TOS.

METHODS

From 1993 to 2005, 25 patients were treated with TOS. A retrospective chart review was performed with institutional review board approval. Demographics, clinical presentation, diagnostic studies, and treatment were evaluated.

RESULTS

Seven male (28%) and 18 female (72%) patients presented between the ages of 12 to 18 years. Thirteen (52%) had vascular TOS (11 venous, 2 arterial), 11 (44%) had neurologic TOS, and 1 had both. Vascular TOS included subclavian vein thrombosis (7), venous impingement (4), and arterial impingement (2). Three patients had hypercoagulable disorders, and 6 had effort thrombosis. Venography was diagnostic in 10 cases. Neurogenic TOS was diagnosed by clinical symptoms. Five patients with subclavian vein thrombosis underwent thrombolysis, with 3 maintaining long-term patency. Of 25 patients, 24 underwent transaxillary first rib resection.

CONCLUSION

Vascular complications are more common in adolescents with TOS than in adults. A diagnostic/treatment algorithm includes urgent venography and thrombolysis for venous TOS and a workup for hypercoagulability. Neurogenic TOS is diagnosed clinically, whereas other studies are rarely beneficial.

Diagnosis and Management of Subclavian Vein Thrombosis: Three Case Reports and Review of Literature

Axillosubclavian vein thrombosis is seen relatively infrequently in clinical practice when compared with lower limb deep-venous thrombosis; however, it is a condition that can result in significant morbidity if managed suboptimally. A multimodal treatment approach has been increasingly adopted with thrombolysis and/or thoracic outlet decompression being favored over anticoagulation alone, although the evidence base to support this approach is limited. In all, 3 cases are reported, which highlight numerous pertinent issues relating to the diagnostic and therapeutic options available.

Exercise-induced deep vein thrombosis of the upper extremity. 1. Literature review

Paget-Schroetter syndrome or effort-related upper extremity deep vein thrombosis is a rare condition that usually afflicts young healthy individuals, most commonly males. The cause is multifactorial but almost always involves extrinsic compression of the subclavian vein at the thoracic inlet, causing venous stenosis from repetitive trauma. The diagnosis of this condition may be difficult, and its delay may contribute to potential complications including thrombosis progression, pulmonary embolism, thrombosis recurrence, and post-thrombotic syndrome. Similarly, the best therapeutic option has not been established and in the lack of evidence-based guidelines, treatment may be extremely challenging especially in children, in whom long-term complications can be particularly disabling.

Thoracic outlet syndrome in an adolescent with bilateral bifid ribs

Reported here is a 13-year-old girl suffering from pain in her right lower neck region and the shoulder for the preceding 2-3 years. She was diagnosed to have right thoracic outlet syndrome due to bifid ribs--caused by the bony fusion of the variant cervical rib. She was operated via supraclavicular approach, whereby the variant cervical rib and the fibrous bands were excised. She was found to be quite improved 1 month after surgery. Thoracic outlet syndrome, a rare disease of childhood, is discussed in the light of the relevant literature.
