Tratamento cirúrgico da forma arterial da síndrome do desfiladeiro torácico associado à costela cervical / Surgical treatment of cervical rib-associated arterial thoracic outlet syndrome

Resumo A forma arterial da síndrome do desfiladeiro torácico é rara e está associada a uma anomalia anatômica, geralmente uma costela cervical. Suas manifestações são muito variadas. Este artigo tem como proposta relatar dois casos de apresentações clínicas distintas: microembolização e aneurisma. Em ambos, uma costela cervical estava presente. O diagnóstico foi realizado através da história, do exame físico, das manobras posturais e das radiografias. A angiotomografia computadorizada proporcionou o detalhe anatômico necessário para o planejamento operatório. O tratamento cirúrgico foi realizado pela abordagem supraclavicular, com sucesso em ambos casos.

Abstract The arterial form of thoracic outlet syndrome is rare and is associated with anatomic anomalies, generally a cervical rib. It has a varied range of manifestations. The aim of this article is to describe two cases with different clinical presentations: microembolization and aneurysm. A cervical rib was present in both cases. Diagnosis was made on the basis of history, physical examination, postural maneuvers, and X-rays. Computed tomography angiography provided the anatomic detail necessary to plan surgery. Surgical treatment was performed via supraclavicular access, successfully, in both cases.

Tratamento de oclusão arterial em membro superior causada por costela cervical / Treatment of upper limb arterial occlusion caused by a cervical rib

Resumo A síndrome da costela cervical ocorre quando o triângulo intercostoescalênico é ocupado por uma costela cervical, deslocando o plexo braquial e a artéria subclávia anteriormente, o que pode gerar dor e espasmo muscular. O objetivo deste estudo é discutir sobre o diagnóstico da síndrome da costela cervical e as possibilidades de tratamento. Este desafio terapêutico descreve a condução clínica e cirúrgica de uma paciente de 37 anos com obstrução arterial em membro superior causada por costela cervical.

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.

A hard left supraclavicular mass in a young boy— is it cancer?

@#A 12-year-old boy was referred to our ENT clinic with an incidentally discovered left supraclavicular mass that was suspected to be malignant. He was asymptomatic and had no prior illnesses. Neck examination found a fixed, hard, non-pulsatile, and non-tender mass measuring 2 cm in diameter in the left supraclavicular fossa. Rest of the ENT assessment, chest and upper limb neurovascular examinations were unremarkable. The patient’s full blood count was within the normal range.

Cervical rib which resembles original thoracic rib presenting with thoracic outlet syndrome (TOS): literature review with a case report / Costilla cervical que se asemeja a una costilla torácica presentándose con síndrome de salida torácica (SST): revisión de la literatura a partir de un caso clínico

The cervical rib (CR) is a rare skeletal anomaly, which generally articulated with the transverse process of the 7th cervical vertebra, and commonly lead to compression of neurovascular structures in the region of the thoracic outlet. CRs are divided into 2 classes as complete and incomplete forms. A clarifying description of the so-called complete CR form has not been found with sufficient information in the literature. We aimed to present a novel case of an anomalous, supernumerary, extra, or additional rib which arises from the seventh cervical vertebra. We present the case of a 23-year-old female who presented with a mass described as slowgrowing since her childhood in the supraclavicular region. The patient complained of pain, numbness, weakness, and difficulty in lifting her right arm, which increased gradually over in the last 6 months. Physical examination revealed findings of thoracic outlet syndrome (TOS). Radiographic analysis demonstrated a huge cervical rib, which resembles the size of a real thoracic rib. The cervical rib was completely resected through the supraclavicular approach. There is not enough data in theliterature about different morphologic properties of CRs. It is presented with 3-D CT images before and after surgical resection. The final version of the transformation of C7 transverse process to an original Thoracic Rib is shown. As a result, the following question presented, can it be called a Zeroth Rib?.

La costilla cervical (CC) es una anomalía esquelética rara, que generalmente se articula con el proceso transverso de la séptima vértebra cervical y generalmente conduce a la compresión de estructuras neurovasculares en la región de salida torácica. Las CC se dividen en 2 clases, como formas completas e incompletas. No se ha encontrado una descripción aclaratoria de la forma completa de CC, con información insuficiente en la literatura. El objetivo de este trabajo fue presentar un nuevo caso de costilla anómala, supernumeraria, extra o adicional que surge de la séptima vértebra cervical. Exponemos el caso de una mujer de 23 años que presentó una masa descrita como de crecimiento lento desde su infancia en la región supraclavicular. La paciente relató dolor, entumecimiento, debilidad y dificultad para levantar el miembro superior derecho, con un aumento gradual de sus síntomas en los últimos 6 meses. El examen físico reveló hallazgos del síndrome de salida torácica (SST). El análisis radiográfico demostró una costilla cervical de tamaño importante, que se asemejaba al tamaño de una costilla torácica real. La costilla cervical fue resecada completamente a través de un abordaje supraclavicular. No hay suficientes datos en la literatura sobre las diferentes características morfológicas de las CC. Se presentan imágenes tridimensionales de tomogracía computarizada, antes y después de la resección quirúrgica. Se muestra la versión final de la transformación del proceso transverso de C7 a una costilla torácica original. Como resultado, se plantea la siguiente pregunta, ¿se puede denominar a esta costilla como "costilla cero"?.

Costilla cervical en pediatría. Presentación de un caso clínico y revisión de la literatura / Cervical rib in pediatrics. Clinical case and literature review / Costela cervical em pediatria. Apresentação de caso clínico e revisão da literatura

Resumen: Introducción: la costilla cervical es una malformación rara que puede dar lugar a diagnósticos diferenciales y que tiene un manejo variable y controvertido. Objetivo: describir una observación clínica de costilla cervical, analizar su manejo y revisar la bibliografía relevante acerca del tema. Observación clínica: varón de 7 años, sano, en el cual, durante un control en salud, se halla una tumoración supraclavicular izquierda. Este fue estudiado, arribándose al diagnóstico de costilla cervical bilateral asintomática. Se tomó una conducta expectante y a diez meses de evolución el paciente ha permanecido asintomático. Discusión y revisión bibliográfica: se destacan los elementos clínicos que deben hacer pensar en el diagnóstico y el potencial de éstos para generar un curso de acción más rápido, con menores molestias para el paciente, menor ansiedad para la familia y menores costos para el sistema. Con base en la revisión bibliográfica, se destaca que la mayoría de los casos pueden manejarse en forma expectante tras informar al paciente y su familia de los elementos que deben motivar una rápida consulta y se mencionan las raras indicaciones de tratamiento activo y las opciones y controversias en torno a éste.

Summary: Introduction: a cervical rib is an uncommon malformation, that may lead to different diagnoses and to variable and controversial treatment procedures. Objectives: to describe a cervical rib case, to analyze how it was treated and to review the relevant bibliography. Clinical observation: healthy 7-year-old male, on whom a supraclavicular tumor was found during a check-up. He was studied until an asymptomatic bilateral cervical rib diagnosis was reached. We have followed-up the case closely and ten months after the finding the patient remains asymptomatic. Discussion and literature review: we have identified clinical elements that may lead to this diagnosis and may speed up the course of action to adopt as well as generate less patient discomfort, less family anxiety and lower system costs. Literature suggests that once the patient and his family have been warned about the symptoms that could require a rapid consultation, most cases can be treated as expected. We also described to them rare indications, available options and controversial issues that may arise.

Cervical Ribs: A Study On Radiographs In A Tertiary Care Hospital Of Assam

Introduction: Cervical rib is the extra rib arises from the seventh cervical vertebra. The prevalence of cervical ribdepends on the population. Cervical ribs are usually asymptomatic but may cause compression of subclavianartery and brachial plexus. Aim is to study the prevalence of cervical rib with associated gender, age group andlaterality (body sides).Materials and Methods: 8000 plain chest radiographs were studied from the month of January to March, 2017,in which 63 chest radiographs were found with cervical ribs. The particulars of the patients were recorded anddata were tabulated and analysed.Results: prevalence of the cervical rib was found to be 0.79% and female outnumbered male.Discussion: cervical rib is a less studied topic in this part of North-East India and thus, this study was conductedon chest radiographs of the patients of a tertiary hospital of this part of India.

Cephalometric and anthropometric data of obstructive apnea in different age groups / Medidas cefalométricas e antropométricas do índice de apneia e hipopneia em diferentes faixas etárias

Introduction: Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. Objective: To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. Methods: A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years). Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. Results: The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone) and PNS-P (distance between the posterior nasal spine and the tip of the soft palate) and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years). Conclusion: Cephalometric measurements MP-H and PNS-P and cervical and waist circumfer- ences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group. .

Introdução: Pacientes com a síndrome da apneia obstrutiva do sono (SAOS) geralmente apresentam alterações na morfologia das vias aéreas superiores e/ou na distribuição da gordura corporal, que podem ocorrer durante a vida e aumentar a gravidade da SAOS com a idade. Objetivo: Correlacionar medidas cefalométricas e antropométricas com a gravidade da SAOS em diferentes faixas etárias. Método: Estudo retrospectivo de medidas cefalométricas e antropométricas de 102 pacientes portadores de SAOS. Os pacientes foram divididos em três faixas etárias (≥20 e <40 anos, ≥40 e <60 anos, e ≥60 anos). Foi realizada correlação de Pearson destas medidas com o índice de apneia-hipopneia (IAH) na amostra completa e depois por faixa etária. Resultados: As medidas cefalométricas MP-H (distância entre o plano mandibular e o osso hioide) e PNS-P (distância entre a espinha nasal posterior e a ponta do palato mole) e as circunferências cervical e abdominal apresentaram correlação estatisticamente significante com o IAH tanto na amostra total quanto na faixa de <40 e ≥ 60 anos. Estas variáveis não mostraram correlação significante com as outras duas faixas etárias (≤ 40 e ≥ 60 anos). Conclusão: As medidas cefalométricas MP-H e PNS-P e as circunferências cervical e abdominal apresentaram correlação com a gravidade da SAOS em pacientes na faixa etária de ≥40 e <60 anos. .

A Case Report of Thoracic Outlet Syndrome with Vascular Complications due to Cervical Rib.

Thoracic outlet syndrome (TOS) is recognized in approximately 8% of the population. Its manifestations may be neurologic or vascular or both, depending on the component of the neurovascular bundle predominantly compressed. The diagnosis is suspected from the clinical picture and investigations. Treatment is initially conservative but persistence of significant symptoms, which occurs in approximately 5% of patients with diagnosed TOS, is an indication for cervical rib and or first rib resection.1 We report the case of a young woman having a left sided cervical rib. She had presented with clinical features of both neurogenic and arterial TOS. Surgical resection of the cervical rib was performed uneventfully through a supraclavicular approach which resulted in complete relief of her symptoms.

Cervical Ribs-A Report of Two Cases.

The Thoracic Outlet is bounded by the first thoracic Vertebra posteriorly, superior border of manubrium sternum anteriorly, and the first rib and costal cartilage laterally. Thoracic outlet syndrome is a general term for a number of disorders producing neurovascular compression over this area. Cervical Rib is a congenital bony abnormality in which an extra rib is present superior to first rib is attached to C7 vertebra. Of the many factors which can cause neurovascular compression, 30% of the cases is due to bony abnormalities. Cervical rib is one of the important bony factors which lead to thoracic outlet syndrome due to the displacement and compression of the neurovascular structures while crossing the thoracic outlet to the upper limb. In the collection of bones in the Institute of Anatomy Madras medical college, cervical ribs were present bilaterally in two specimens. The present paper will definite be useful to clinicians while dealing with thoracic outlet syndrome.

Synostosis of First Costomanubrial Joint.

The rare congenital anomaly of ribs was found incidentally during routine osteology classes. This type of abnormality of first rib May leads to compression of Neurovascular bundle and causes thoracic outlet syndrome. We are reporting a case of Synostosis of first rib, which we come across during osteology classes at Department of Anatomy, KBNIMS, Gulbarga, Karnataka, India. The specimen showed fusion of first rib with sternum on both sides which is very rare. As far as the literature referred there was no such kind of anomaly reported. Knowledge of such anomalies is an important to know, especially for surgeons and radiologists for interpretation.

Síndrome do desfiladeiro torácico - ressecção de costela cervical por videotoracoscopia / Thoracic outlet syndrome - cervical rib resection through videothoracoscopic surgery

A base do tratamento cirúrgico da Síndrome do Desfiladeiro Torácico (SDT) é a ressecção da primeira costela, podendo associar-se à escalenectomia ou ainda à ressecção de costela cervical. Esta última é feita tradicionalmente por meio de um acesso supraclavicular ou mesmo axilar, o qual é tecnicamente mais trabalhoso. Pode ser realizada também por meio de acesso paraescapular. Embora tecnicamente atrativa e associada à menor invasividade e maior segurança, com ótimo resultado estético, a ressecção da primeira costela torácica, por intermédio de cirurgia videoassistida transaxilar ou pela técnica videotoracoscópica, é pouco relatada na literatura, e nenhuma referência foi encontrada sobre ressecção de costela cervical mediante essa técnica. Neste artigo, apresentamos essa inovação cirúrgica realizada com sucesso para ressecção de costela cervical em duas pacientes.

The basis of Thoracic Outlet Syndrome (TOS) surgical treatment is the first rib resection and may be associated with scalenectomy or cervical rib resection. The latter is traditionally done through a supraclavicular or axillary access, which is the most technically challenging. It can also be achieved through parascapular access. Although technically attractive and associated with less invasiveness and increased security, with excellent aesthetic results, the first thoracic rib resection via video-assisted transaxillary surgery or videothoracoscopic technique is seldom reported in the literature, and no reference was found on cervical rib resection through this technique. In this article, we introduced this innovation successfully performed for surgical cervical rib resection in two patients.

Three Cases of Cervical Rib / 대한이비인후과학회지

Cervical rib is a normal asymptomatic congenital bone abnormality that occurs in 0.4% of the population; 70% of these cases are bilateral. Cervical ribs are found incidentally on routine radiographs, though sometimes patients complain of a hard or pulsatile neck mass in the supraclavicular area. Although most of these ribs produce no symptoms and need no therapy, a few cases are symptomatic and require treatment. Furthermore, a cervical rib can displace the great vessels superiorly and may cause iatrogenic hemorrhage during neck surgery. Thus, otorhinolaryngologists should be aware of the diagnosis and management of this condition in patients with a neck mass. Here, we report three cases of cervical rib and include a review of literature.

Fístula linfática após tratamento cirúrgico de síndrome do desfiladeiro torácico à direita / Chylothorax after surgical treatment of right-sided thoracic outlet syndrome

A fístula linfática como complicação de correção de síndrome do desfiladeiro torácico é um evento muito raro. Relatamos um caso de fístula linfática à direita e apresentamos uma breve revisão do tratamento de quilotórax pós-cirúrgico.

Chylothorax as a complication of the surgical treatment of thoracic outlet syndrome is a quite rare event. We report a case of right-sided chylothorax and present a brief review on the treatment of postoperative chylothorax.

Síndrome do desfiladeiro torácico neurogênica verdadeira: relato de caso / True neurogenic thoracic outlet syndrome

A síndrome do desfiladeiro torácico neurogênica verdadeira é uma condição rara, motivada pelo angustiamento do plexo braquial inferior e médio, quando da sua passagem por um reduzido espaço inter-escalênico. Os autores descrevem o caso de uma jovem de 16 anos que apresentou atrofia e fraqueza da mão direita de início insidioso e evolução progressiva. Seus exames neurológico, de imagem e eletroneuromiográfico apontaram para síndrome do desfiladeiro torácico neurogênica verdadeira à direita na presença de costela cervical bilateral. Num acompanhamento de 22 meses após a ressecção da costela cervical do lado sintomático, houve melhora da função motora mantendo-se amiotrofia tenar.

The true neurogenic thoracic outlet syndrome is a very rare condition caused by involvement of the inferior and medium brachial plexus cords in a reduced interscalenic space. The authors describe a 16-year-old girl with insidious wasting and progressive weakness of her right hand. Her neurologic examination, images, and eletroneuromiographic results point to a right side true neurogenic thoracic outlet syndrome with bilateral cervical rib. After a twenty-two months follow-up post right cervical rib resection, she feels better from the motor function aspect, but maintains tenar atrophy.

Complicações arteriais da síndrome do desfiladeiro torácico / Arterial complications of thoracic outlet syndrome

As manifestações clínicas da síndrome do desfiladeiro torácico são predominantemente neurológicas, sendo as complicações arteriais raras, mas potencialmente graves. Entre elas, devemos citar os aneurismas com complicações embólicas e a trombose. Os autores relatam o caso de uma mulher de 37 anos com costela cervical bilateral que apresentou embolia no membro superior direito originada de um aneurisma pós-estenótico da artéria subclávia direita, além de apresentar ectasia da subclávia esquerda também por compressão.

The clinical manifestations of thoracic outlet syndrome are mainly neurological. Although arterial complications are rare, they are potentially severe. Among these are aneurysms associated with embolism and thrombosis. The authors report a case of a 37 year-old woman with bilateral cervical rib that developed embolism in the right upper limb from a poststenotic right subclavian artery aneurysm and dilatation of the left subclavian artery, both due to compression.

Cervical Rib Syndrome: 2 Cases Report / 대한정형외과학회잡지

Cerivical rib syndrome, one of four common causes of thoracic outlet syndromes, have similar symptoms which accidentally discovered in simple x-ray and needs to be distinguished with other syndromes. Thoracic outlet syndromes are classified according to anatomical structures that causes symptoms; cervical rib syndrome, scalenus anticus syndrome, costoclavicular syndrome and hyperabduction syndrome. Various treatments for thoracic outlet syndromes have been introduced, such as; conservative care, excision of cervical rib and first rib and release of anterior scalenus muscle by supraclavicular approach and excision of cervical rib and first rib by axillary approach. We would like to report a case on a 16 years old girl and a 21 years old man who had cervical rib syndrome and treated successfully without excision of the first rib but excised cervical rib and released anterior scalenus muscle by supraclavicular approach.

Síndrome del opérculo torácico: revisión bibliográfica / Thoracic operculum syndrome: bibliographic review

En el presente caso clínico valoramos a una paciente con síndrome del opérculo toráxico, la cual padecía de una larga historia de síntomas y signos variables e inespecíficos en su miembro superior derecho, cuello y región occipital. El estudio semiológico, de imágenes y fisiológico de esta paciente, mostró que el cuadro que padecía, se debía a una costilla cervical redundante. La paciente mejoró mucho con el tratamiento médico, postergando una intervención quirúrgica si el caso en un futuro lo requiera. Este síndrome afecta con mayor frecuencia a mujeres de entre 10 y 50 años, y conlleva a una serie de limitaciones físicas, y posteriormente anatómicas, que afectarían la calidad de vida del paciente; su identificación oportuna nos permite prevenir dicha evolución y en muchos de los casos, ya sea con tratamiento médico y sobre todo con tratamiento quirúrgico, eliminar la causa que desencadenó este síndrome.

In this opportunity we examined a female patient with thoracic operculum syndrome. She had had a long history of changing and no specific symptoms and signs in her right upper limb, neck and occipital region. Studies of signs, images, and physiology of this patient showed that the abnormality she suffered was caused by a redundant cervical rib. The patient got a lot better with medical treatment postponing surgery that could be necessary in the future. This syndrome affects more frequently to women between 10 and 50 years old and implies many physical limitations and subsequently anatomical ones that would affect the quality of life of the patient; its timely identification allows us to prevent such an evolution, and in many cases either with medical treatment or specially with surgical treatment eliminate the cause that triggered this syndrome.
