Síndrome del nervio dorsal escapular en un adulto / Dorsalscapular nerve syndrome in an adult

Se presenta el caso clínico de un paciente de 47 años de edad, quien acudió al Servicio de Ortopedia y Traumatología del Hospital Docente Clinicoquirúrgico Joaquín Albarrán de La Habana por presentar dolor en el cuello irradiado al miembro superior izquierdo. En la exploración física se destacó atrofia de los músculos romboides de la escápula izquierda y deformidad alar, acentuada durante la maniobra. Se realizó radiografía y electromiografía; en la primera, se observó costilla cervical supernumeraria izquierda y, en la segunda, lesión del nervio dorsal escapular, por lo cual se diagnosticó síndrome del nervio dorsal escapular secundario a síndrome del escaleno anterior. Se indicó tratamiento fisioterapéutico y el paciente evolucionó satisfactoriamente.

The case report of a 47 years patient is presented, who went to the Orthopedics and Traumatology Service of Joaquín Albarrán Teaching Clinical Surgical Hospital in Havana due to a pain in the neck irradiated to the left superior member. In the physical exploration atrophy of the left scapula romboid muscles and alar deformity were notable, accented during the maneuver. Radiography and electromyography were carried out; in the first one, left supernumerary cervical rib was observed and, in the second one, dorsalscapular nerve leison, reason why the secondary dorsal scapular nerve syndrome to anterior scalene syndrome was diagnosed. Physiotherapeutic treatment was indicated and the patient had a favorable clinical course.

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.

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"?.

Bases ósseas e musculares do corte comercial de pescoço de jacaré-do-pantanal (Caimanyacare Daudin, 1802) / Bone and muscular bases of commercial cut from the neck of Yacare Caiman (Caiman yacare Daudin, 1802)

O jacaré-do-pantanal (Caiman yacare) é uma espécie abundante no ecossistema do Pantanal. Sua exploração comercial está regulamentada desde 1990 e se tornou um agronegócio em expansão. Para atender essa demanda, uma unidade processadora instalada em Mato Grosso, vem comercializando carne de jacaré em diferentes cortes, entre os quais o filé de dorso, oriundo do pescoço, nos últimos quatro anos. O objetivo desta pesquisa foi descrever os músculos e correspondentes bases ósseas desse corte. Para a descrição de ossos, utilizaram-se seis carcaças desossadas de exemplares juvenis de jacaré-do-pantanal, além de um exemplar adulto obtido após morte do animal, por doação, do Zoológico da UFMT. Os ossos foram macerados em água corrente, clareados com solução de água oxigenada a 10 volumes, e seus detalhes anatômicos foram descritos. Para descrever o músculo, 24 exemplares juvenis foram obtidos após abate e esfola, conservados em freezer e descongelados quando utilizados, sem qualquer fixação. Após a evisceração, foram dissecados em ambos os antímeros, para verificação de simetria de ocorrência, fixações musculares, relacões de sintopia, forma e arquitetura muscular. Verificou-se que a coluna cervical em C. yacare apresenta nove vértebras cervicais (VC), associadas com as respectivas costelas, que servem de base principal ao filé de dorso, que é constituído pela musculatura cervical, exceto os músculos intertransversais cervicais e intercostais cervicais externos.

The yacare Caiman (Caiman yacare) is an abundant species in the Pantanal ecosystem. Commercial exploitation was regulated in 1990 and has become a thriving business. In order to fulfill this demand, a processing plant settled in Mato Grosso state, Brazil, has been supplying for the last four years different cuts of Pantanal Caiman meat, including the "filé de dorso" (back sirloin) obtained from the neck. The aim of this study was to describe the muscles and corresponding bones related to this cut. To describe the bones, we used six boned carcasses from juvenile yacare Caiman, as well as an adult specimen obtained after animal death, by donation from the Federal University of Mato Grosso Zoo. The bones were macerated in water, bleached with 10 volume-hydrogen-peroxide solution, and their anatomical details were recorded. In order to describe the muscles, 24 juvenile specimens were obtained after slaughter and skinning, preserved in a freezer at -20oC, and thawed at the time of use, without any fixation. After evisceration, the specimens were dissected on both sides to verify symmetry of structures, muscle attachments, sintopy relations, shape, and muscular architecture. The cervical spine of C. yacare features nine cervical vertebrae (CV) associated to their ribs, serving as the main base for the back sirloin cut, which is formed by neck muscles, except for the intertransverse cervical and external intercostal cervical muscles.

Clinical and cytogenetic features of a Brazilian sample of patients with phenotype of oculo-auriculo-vertebral spectrum: a cross-sectional study / Características clínicas e citogenéticas de uma amostra brasileira de pacientes com fenótipo de espectro óculo-aurículo-vertebral: um estudo transversal

CONTEXT AND OBJECTIVE: Oculo-auriculo-vertebral spectrum (OAVS) is considered to be a defect of embryogenesis involving structures originating from the first branchial arches. Our objective was to describe the clinical and cytogenetic findings from a sample of patients with the phenotype of OAVS. DESIGN AND SETTING: Cross-sectional study in a referral hospital in southern Brazil. METHODS: The sample consisted of 23 patients who presented clinical findings in at least two of these four areas: orocraniofacial, ocular, auricular and vertebral. The patients underwent a clinical protocol and cytogenetic evaluation through high-resolution karyotyping, fluorescence in situ hybridization for 5p and 22q11 microdeletions and investigation of chromosomal instability for Fanconi anemia. RESULTS: Cytogenetic abnormalities were observed in three cases (13%) and consisted of: 47,XX,+mar; mos 47,XX,+mar/46,XX; and 46,XX,t(6;10)(q13; q24). We observed cases of OAVS with histories of gestational exposition to fluoxetine, retinoic acid and crack. One of our patients was a discordant monozygotic twin who had shown asymmetrical growth restriction during pregnancy. Our patients with OAVS were characterized by a broad clinical spectrum and some presented atypical findings such as lower-limb reduction defect and a tumor in the right arm, suggestive of hemangioma/lymphangioma. CONCLUSIONS: We found a wide range of clinical characteristics among the patients with OAVS. Different chromosomal abnormalities and gestational expositions were also observed. Thus, our findings highlight the heterogeneity of the etiology of OAVS and the importance of these factors in the clinical and cytogenetic evaluation of these patients. .

CONTEXTO E OBJETIVO: O espectro oculoauriculovertebral (EOAV) é considerado um defeito de embriogênese envolvendo estruturas originadas a partir dos primeiros arcos branquiais. Nosso objetivo foi descrever os achados clínicos e citogenéticos de uma amostra de pacientes com fenótipo de EOAV. TIPO DE ESTUDO E LOCAL: Estudo transversal em um hospital de referência no sul do Brasil. MÉTODOS: A amostra foi composta de 23 pacientes que apresentaram achados clínicos em pelo menos duas das quatro áreas: orocraniofacial, oculares, auriculares e vertebrais. Os pacientes foram submetidos a um protocolo clínico e avaliação citogenética através do cariótipo de alta resolução, hibridização in situ fluorescente para as microdeleções 5p e 22q11 e pesquisa de instabilidade cromossômica para anemia de Fanconi. RESULTADOS: Alterações citogenéticas foram observadas em três casos (13%) e consistiam de: 47,XX,+mar; mos 47,XX,+mar/46,XX e 46,XX,t(6;10)(q13;q24). Observamos casos de EOAV com história de exposição gestacional à fluoxetina, ácido retinoico e crack. Um dos nossos pacientes foi um gêmeo monozigótico discordante que teve restrição de crescimento assimétrica durante a gravidez. Nossos pacientes com EOAV foram caracterizados por um amplo espectro clínico e alguns apresentaram achados clínicos atípicos como um defeito de redução de membro inferior e um tumor do braço direito, sugestivo de hemangioma/linfangioma. CONCLUSÕES: Verificamos grande variedade de características clínicas entre os pacientes com EOAV. Também foram observadas diferentes anomalias cromossômicas e exposições gestacionais. Assim, nossos achados salientam a heterogeneidade da etiologia do EOAV e a importância desses fatores na avaliação clínica e citogenética desses pacientes. .

Síndrome del outlet torácico: una patología siempre quirúrgica? / Thoracic outlet syndrome: an always surgical entity?

Objetivo: el objetivo de este trabajo es analizar los resultados obtenidos en una serie de cirugías realizadas en esta patología. Material y métodos: se analizaron todos los casos de cirugías de nervios efectuados en el período 2003-2012, separando los casos con diagnóstico de outlet torácico operados con un período de seguimiento postoperatorio mínimo de 6 meses. Se buscaron los siguientes datos: edad, sexo, presencia de síntomas sensitivos y/o motores, tipo de outlet (verdadero o disputado), resultado de los estudios neurofisiológicos y de imágenes, resultado de la cirugía, complicaciones postoperatorias y recidivas. Resultados: se incluyeron 31 cirugías realizadas en 30 pacientes, 9 con diagnóstico de OTV (8 mujeres) con un promedio de edad fue de 24.3 años, y 21 con OTD (18 mujeres) de 37.4 años en promedio. Un 90% de todos los casos de outlet presentaron alteraciones neurofisiológicas preoperatorios, y los estadios imagenológicos fueron anormales en 66.6%. Una vez realizada la exploración, el 100% de los OTV presentó una alteración anatómica claramente relacionada con la sintomatología, hecho observado sólo en el 36.7% de los OTD operados. El 87.5% de los OTV mejoraron sus síntomas sensitivos luego de la cirugía, mientras que 77.7% mejoraron desde el punto de vista motor. Por el contrario, 45.4% de los OTD mejoraron permanentemente, 36.3% no tuvieron cambios, 13.6% mejoraron transitoriamente y 405% (un caso) empeoró. Las complicaciones postoperatorias fueron más frecuentes aunque transitorias en el grupo de OTV (3 casos sobre 9 operados, 33.3%) que en los OTD (3 casos sobre 22, un 13.6%). Conclusión: el OTV es una patología infrecuente cuyo tratamiento quirúrgico suele evolucionar favorablemente. En cambio, el OTD constituye un diagnóstico de exclusión y su tratamiento quirúrgico da un resultado bueno aunque inferior al del OTV.

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.

Costela intratorácica: relato de caso / Intrathoracic rib: a case report

Costela intratorácica é definida como uma anomalia congênita rara, possivelmente causada por uma fusão incompleta dos processos cefálico e caudal dos esclerótomos durante a embriogênese. Frequentemente é achado incidental, porém, pode estar associada a malformações vertebrais e a alguns sintomas como dor torácica. O quadro apresentado é de costela intratorácica à esquerda, associada a malformação vertebral, com quadro clínico inespecífico.

Intrathoracic rib is defined as a rare congenital anomaly, possibly caused by an incomplete fusion of cephalic and caudal processes of sclerotomes during embryogenesis. Frequently, such abnormality is incidentally found, but may be associated with vertebral malformation and some symptoms such as chest pain. The authors report the case of a patient with left-sided intrathoracic rib in association with vertebral malformation, with a non-specific clinical picture.

Teratoma cervical congênito gigante: relato de caso e revisão quanto às opções terapêuticas / Giant congenital cervical teratoma: case report and review about therapeutic options

OBJETIVO:Relatar um caso de teratoma cervical congênito, destacando a gravidade e as dificuldades terapêuticas associadas. DESCRIÇÃO DO CASO: Mãe de 30 anos, com gestação por fertilização assistida. Com 23 semanas, diagnosticada malformação cervical fetal à direita. Parto cesáreo por indicação fetal com 31 semanas. Recém-nascido masculino, peso ao nascer de 1800g, Apgar 4 e 9, com volumoso processo expansivo à direita, ocupando toda a região cervical, comprometendo a mandíbula e estendendo-se para o terço superior do tórax. Com 40 horas de vida, apresentou insuficiência cardíaca congestiva de alto débito por roubo de fluxo pelo tumor. A partir de 54 horas de vida, houve progressiva deterioração hemodinâmica e respiratória, com hipotensão, anúria e labilidade de oxigenação, refratárias às aminas vasoativas, reposição de volume e aumento do suporte ventilatório. Indicada abordagem cirúrgica para ressecção tumoral, todavia o paciente não apresentou estabilidade clínica que permitisse seu transporte ao centro cirúrgico e faleceu com 70 horas de vida. COMENTÁRIOS: O caso demonstra as dificuldades relacionadas à abordagem pós-natal dos teratomas cervicais volumosos. Apesar do diagnóstico pré-natal, o paciente evoluiu com obstrução de vias aéreas, complicada por um choque cardiogênico refratário, que culminou no óbito. A abordagem intraparto é fundamental nesses pacientes, consistindo em exérese tumoral, enquanto a manutenção da circulação materno-fetal permite a oxigenação fetal contínua. A evolução neonatal no caso descrito é condizente com a literatura que mostra prognóstico reservado quando não é realizada a abordagem cirúrgica intraparto.

OBJECTIVE:To report a case of congenital cervical teratoma, highlighting the severity and the therapeutic difficulties associated. CASE DESCRIPTION: A 30-year old mother, with pregnancy by assisted fertilization. At 23 weeks, a cervical fetal malformation was diagnosed. A cesarean section was indicated with 31 weeks due to fetal distress. A male newborn infant with birth weight of 1800g and Apgar score of 4/9 presented a large right cervical tumor, with extensions to the mandible and to the upper chest. Patient presented congestive heart failure due to flow steal by the tumor 40 hours after birth, which caused progressive respiratory, hemodynamic and renal deterioration refractory to vasopressors, volume replacement and increased ventilatory support. Tumor resection was indicated, but the clinical instability of the patient did not allow his transport to the operating room and the infant died 70 hours after birth. COMMENTS: The case is representative of the difficulties related to postnatal treatment of bulky cervical teratomas. Despite prenatal diagnosis, the patient developed airway obstruction, complicated by refractory cardiogenic shock. The surgical approach during delivery is crucial for survival. Nowadays, management includes surgical removal of the tumor while maintaining the maternal-fetal circulation, allowing continuous fetal oxygenation. The clinical course described in the case is consistent with the literature that reports poor prognosis when the intra-partum surgical approach is not performed.

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.

Cervical rib.

Cervical rib is a supernumerary rib. It is one of the deformities of the musculoskeletal system. According to Terves and Keith, there is always a rudiment of a cervical rib in the fetus which usually disappears but in 1-2 %, it persists throughout life. Only a part of this percentage has symptoms. Genetic Factors may play a role. Clinical important: It causes pressure on brachial-plexus or subclavian artery. These structures are entrapped between the cervical rib and scaleneus muscle. There is positive Adson’s sign i.e. radial pulse is lost in the arm during abduction and external rotation of the shoulder. There is compression of brachial plexus which causes weakness of muscles of the hand near base of the thumb. This is known as THORACIC OULET SYNDROME. A supernumerary rib develops from anterior tubercle of cervical vertebra- like Meckel’s Diverticulum. Incidence 5 – 6 % .Mostly an incidental finding

Surgical management of thoracic outlet compression syndrome

Thirty patients suffering from thoracic outlet compression syndrome [TOCS] were treated over 15 years [1982-2002] in King Fahad Hospital of the University, Al-Khohbar, Saudi Arabia. The presenting symptoms included pain [86.6%], paresthesia [30%], and weakness [10%]. Thirteen patients underwent surgical intervention; 7 females and 6 males. Group I, 9 patients operated through transaxillary and Group II, 4 operated through five supraclavicular approaches. Group I showed excellent result in 8 patients [88.9%]. In Group II, 2 patients had excellent outcome and 2 with three operations had poor outcome. The follow-up period was at least one year. Our results showed transaxillary approach is effective for relief of pain in TOCS. It is concluded that our experience over 15 years had shown that transaxillary approach is an effective method for the treatment of TOCS in neurogenic type and those with minimal vascular compression that do not need direct surgical intervention

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.

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.

Surgical Experiences of Arterial Thoracic Outlet Syndrome (TOS)

PURPOSE: We wanted to investigate the clinical features and treatment results of arterial type thoracic outlet syndrome (a-TOS). METHODS: We retrospectively reviewed the surgical treatments (n=9) of a-TOS for 6 patients (4 primary, 2 secondary, males: 100%, mean age: 39.6 years). For achieving thoracic outlet decompression, we performed cervical rib resection (n=6) and scalenectomy (n=7) through a supraclavicular incision. Among the primary TOS patients, 4 patients required subclavian artery (SCA) reconstruction. Arterial bypass were performed using saphenous vein grafts for 2 patients with secondary a-TOS. RESULTS: As an underlying cause of primary a-TOS, all the patients revealed bilateral cervical ribs whereas the secondary a-TOS were caused by malunion of clavicular fractures. All the patients presented with hand ischemia: resting pain in 4, cyanosis in 4, tingling sense in 4, pallor in 2 and finger tip gangrene in 2. After surgical treatment, the ischemic symptoms improved in all patients, but not to a satisfactory levels in the patients with distal arterial emboli. We experienced pneumothorax, transient phrenic nerve palsy and winged scapula as the operative complications. CONCLUSION: To achieve better treatment outcomes, we recommend early surgical treatment before the occurrence of distal arterial embolization even in the asymptomatic patients who reveal subclavian artery abnormalities. For surgical treatment of a-TOS, the supraclavicular approach combined with infraclavicular incisions offers good exposure for achieving thoracic outlet decompression and SCA reconstructions.

Shape and Incidence of Rib Variations in Chest Radiographs / 결핵

BACKGROUND: The literature on variations of rib is limited. Very little has been written in the radiological journal of this country on the subject. It seemed of interest to investigate the nature and incidence of congenital variations in a series of routine chest roentgenograms. The topic of rib variations has not been covered extensively in the radiological journals in Korea. This has presented an opportunity to investigate the nature, type, shape and incidences of congenital rib variations in normal Korean adults from a series of routine roentgenograms. METHODS: Chest radiographs of 5,000 adults (,) who visited our hospital for a routine check-up or for employment physical examinations from January 1996 to September 1998, were consecutively reviewed. The sex distribution consisted of 2,827 male males and 2,173 females (ratio of 1.3:1) with the age range between 19 and 65 years (mean age: 34.6 years). The chest PAs was were analyzed for the presence, type, location, and shape of the rib variations (.) From this data, and we the incidence of each type of variations was calculated. RESULTS: Seventy-six of the 5000 adults (1.52%), 63 male (2.23%) and 13 female (0.6%), showed 88 cases of rib variation (Table 1). Bifid rib (n=35) was the The most common variation was the bifid rib (n=35), followed by hypoplasia of the rib (n=22), flaring of the rib (n=18), bridging of the ribs (n=7), cervical ribs (n=3), and fusion of between ribs (n=3) (Table 2). (New paragraph)Bifid The bifid rib (Table 1) was found most frequent in the right fourth rib (12/35, 34.3%), followed by the left fifth rib (6/35, 17.1%) and right third rib (6/35, 17.1%). Hypoplasia of the rib was common in first rib (20/22, 90.9%). Flaring of the rib was common at fourth rib (8/18. 44.4%, right and left combined) (,) and bridging between ribs was common between first and second rib (3/7, 42.9%). CONCLUSION: The percentage of incidence of rib variations in adults was 1.52%. Bifid rib was the most common variation, followed by hypoplasia, flaring, bridging, cervical rib, and fusion of ribs(,) in decreasing order.

Arterial Thoracic Outlet Syndrome: A Case Report / 대한흉부외과학회지

A 17-year-old-boy with a bilateral incomplete cervical rib, upon abduction of his left arm at 45 degrees, had immediately begun to show symptoms of severe tingling, claudication, pallor, and weakness of his left upper extremity. These symptoms were aggravated at 90 degrees, leaving him debilitated from his work in the printing office. Transfemoral positional subclavian arteriography revealed total occlusion of the subclavian artery immediately distal to a cervical rib during 90 degrees abduction. Resection of the anterior scalene and medial aspect of the middle scalene muscles, cervical and first ribs, and arteriolysis were performed via a combined supraclavicular and infraclavi cular approach. He has returned to work as a printer with marked relief of symptoms and has remained asymptomatic over follow-up periods of 10 months.

Congenital High Scapula Associated with Anomaly of the Acromion: A Case Report / 대한정형외과학회잡지

Congenital high scapula, more commonly referred to as Sprengel's deformity, was first described by Eulenberg in 1863. Usually other congenital anomalies are associated such as absent or fused ribs, chest wall asymmetry, Klippel-Feil syndrome, cervical ribs, congenital scoliosis, cervical spina biffida was treated with the excision of the elongated acromion and the resection of prominent elongated acromion to be described is an extremely rare malformation. We experienced one case of congenital high scapula associated with anomaly of the acromion, which was treated with the excision of the elongated acromion and the resection of prominent supermedial border of the scapula for the purpose of the cosmetic and functional correction. After 1 year follow up, abduction was improved by only 10 degrees in the glenohumeral joint with the definite cosmetic improvement.
