Informe de un caso clínico con síndrome de Paget-Schroetter / Report of a clinical case with Paget-Schroetter Syndrome

Introducción: El síndrome de Paget-Schroetter (SPS) es una trombosis venosa profunda primaria del complejo venoso subclavio-axilar que ocurre después del uso repetitivo y extenuante de los hombros y los brazos. Muestra una incidencia de 1 por 100 000 personas al año. Se informa con mayor frecuencia en atletas jóvenes. Objetivo: Presentar un caso inusual de síndrome de Paget-Schroetter en un individuo joven no deportista. Caso clínico: Varón militar activo de 24 años de edad, sin antecedentes patológicos personales, que ingresó con inflamación del miembro superior izquierdo de 24 horas de evolución. Presentó una trombosis de la vena cefálica izquierda después de un esfuerzo físico de carga y descarga. Tras descartar trastornos secundarios de hipercoagulabilidad se le diagnosticó un SPS. Se le informó de la opción de intervención quirúrgica, pero la rechazó. El diagnóstico fue confirmado con ecografía Doppler y tratado con anticoagulación endovenosa al inicio y luego por vía oral durante 6 meses. Durante el seguimiento no se evidenció trombosis crónica de la vena cefálica izquierda ni formación de intervalo de colaterales vasculares. Conclusiones: El SPS es una condición clínica que necesita un alto índice de sospecha y un diagnóstico oportuno, por tanto, los médicos deben estar atentos a esta rara entidad para su reconocimiento temprano y derivación oportuna a cirugía vascular(AU)

Introduction: Paget-Schroetter syndrome (PSS) is a primary deep vein thrombosis of the subclavian-axillary venous complex that occurs after repetitive and strenuous use of the shoulders and arms. It shows an incidence of 1 per 100,000 people per year. It is reported more frequently in young athletes. Objective: To present an unusual case of Paget-Schroetter syndrome in a young non-athlete individual. Clinical case: 24-year-old active military man with no personal pathological history is presented, who was admitted with inflammation of the left upper limb of 24 hours of evolution. He presented a thrombosis of the left cephalic vein after a physical effort of loading and unloading. After ruling out secondary hypercoagulability disorders, he was diagnosed with SPS. He was informed of the option of surgical intervention, but he declined it. The diagnosis was confirmed with Doppler ultrasound and treated with intravenous anticoagulation at the beginning, and then orally for 6 months. During the follow-up of the patient, there was no evidence of chronic thrombosis of the left cephalic vein or interval formation of vascular collaterals. Conclusions: SPS is a clinical condition that requires a high index of suspicion and prompt diagnosis, therefore, physicians must be attentive to this rare entity for early recognition and timely referral to vascular surgery(AU)

Prevention of recurrent thrombotic events in children with central venous catheter-associated venous thrombosis.

Central venous catheters (CVC) are the most significant risk factor for pediatric venous thromboembolism (VTE). After an index CVC-associated VTE (CVC-VTE), the role of secondary prophylaxis for subsequent CVC placement is uncertain. Aims of this single-center retrospective study were to evaluate the efficacy of secondary prophylaxis for patients with a prior CVC-VTE and identify risk factors associated with recurrent VTE in patients less than 19 years with an index CVC-VTE between 2003 and 2013. Data collection included clinical and demographic factors, subsequent CVC placement, secondary prophylaxis strategy, recurrent VTE, and bleeding. Risk factors for recurrence and effectiveness of secondary prophylaxis were evaluated using survival and binomial models. Among 373 patients with an index CVC-VTE, 239 (64.1%) had subsequent CVC placement; 17.4% (65/373) of patients had recurrent VTE, of which 90.8% (59/65) were CVC-associated. On multivariable survival analysis, each additional CVC (hazards ratio [HR] 12.00; 95% confidence interval [CI] 2.78-51.91), congenital heart disease (HR 3.70; 95% CI 1.97-6.95), and total parenteral nutrition dependence (HR 4.02; 95% CI 2.23-7.28) were associated with an increased hazard of recurrence. Full dose anticoagulation for secondary prophylaxis was associated with decreased odds of recurrent CVC-VTE (odds ratio [OR] 0.35; 95% CI 0.19-0.65) but not prophylactic dosing (OR 0.61; 95% CI 0.28-1.30). Only 1.3% of CVCs experienced major bleeding with prophylactic or full-dose anticoagulation. In summary, children with CVC-VTE are at increased risk for recurrent VTE. Secondary prophylaxis with full-dose anticoagulation was associated with a 65% reduction in odds of thrombotic events.

En las campañas de vacunación, como en la actual situación de COVID-19, es habitual que los países señalen posibles efectos adversos después de la vacunación. Esto no significa necesariamente que los eventos estén relacionados con la vacunación en sí, pero es necesario investigarlos. También muestra que el sistema de vigilancia funciona y que existen controles efectivos. La Organización Mundial de la Salud (OMS) está en contacto regular con la Agencia Europea de Medicamentos (EMA) y otras autoridades reguladoras del mundo para obtener la información más reciente sobre la seguridad de todas las vacunas para COVID-19.

Resección de la primera costilla por videotoracoscopía en síndrome de Paget-Schroetter / Resection of the first rib by video thoracoscopy in Paget-Schroetter syndrome

Resumen El síndrome del opérculo torácico se refiere a una serie de signos y síntomas que se producen por la compresión del paquete vásculo-nervioso en la unión costo-clavicular. El síndrome de Paget-Schroetter (SPS) se define como la trombosis primaria, espontánea o de esfuerzo de la vena subclavia. Las vías de abordaje quirúrgicas tradicionales utilizadas para descomprimir el opérculo torácico son la trans axilar y las claviculares (supra e infra). El objetivo del estudio fue describir nuestra experiencia en la resección de la primera costilla por videotoracoscopía (VATS). Este es un estudio descriptivo observacional utilizando una base de datos prospectiva con análisis retrospectivo desde enero de 2017 a marzo de 2020. Se incluyeron 9 pacientes con diagnóstico de SPS en los que se resecó la primera costilla por VATS. En un paciente el procedimiento fue bilateral por presentar trombosis espontánea en ambas venas subclavias. De los 9, 6 eran mujeres. La edad media fue de 30.7 ± 10.7 años. La estadía hospitalaria media fue de 3.1 ± 0.5 días. Uno fue re-operado por hemotórax. No se detectaron recurrencias en el seguimiento a mediano-largo plazo. La resección de la primera costilla por VATS es un procedimiento seguro y factible. La misma, a diferencia de los abordajes tradicionales, puede ser resecada bajo visión directa de todos los elementos del opérculo torácico. Sin embargo, esta técnica requiere un manejo avanzado en cirugía toracoscópica.

Abstract Thoracic outlet syndrome (TOS) refers to a number of signs and symptoms that arise from compression of the neurovascular bundle at the costoclavicular junction. Paget-Schroetter syndrome is defined as the primary, spontaneous or effort thrombosis of the subclavian vein. The supraclavicular and trans-axillary approaches are currently the most commonly used for first rib resection. The aim of this article was to describe our experience in a minimally invasive approach (VATS) of first rib resection for primary venous thoracic outlet and the associated outcomes. This is a descriptive observational study using a retrospective analysis of a prospective database from January 2017 to March 2020. Nine patients underwent video thoracoscopic first rib resection due to PagetSchroetter syndrome (one bilateral procedure). Ten thoracoscopic first rib resections were performed. There were 6 female and 3 male patients, with a mean age of 30.7 ± 10.7 years. The mean length of hospital stay was 3.1 ± 0.5 days. No complications were recorded intraoperatively. One patient had to be re-operated because of hemothorax. There were no recurrences in a follow-up of at least 12 months. VATS resection of the first rib is a safe and feasible procedure and can be performed under direct vision of thoracic outlet elements. However, the technique requires experience with thoracoscopic surgery. The outcomes associated with our technique are comparable with the outcomes related to other current standards of care.

Catheter-related deep vein thrombosis in newborn infants. / Trombosis venosa profunda asociada al uso de catéteres en recién nacidos.

INTRODUCTION: In neonatology, more than 90 % of deep vein thromboses are related to catheter use. The objective of this study was to determine the incidence and risk factors associated with central venous catheter-related deep vein thrombosis. POPULATION AND METHODS: Observational and analytical study conducted in a prospective cohort. All central venous catheters were included using consecutive, non-random sampling. The screening protocol included a daily clinical examination and a Doppler ultrasound (7-10 days after insertion and/or 72 h after removal). Follow-up: from catheter insertion to catheter removal, death or patient counter-referral. The incidence density rate per 1000 catheter-days was estimated with its corresponding 95 % confidence intervals (CIs), and risk factors, using Cox multivariate analysis. RESULTS: Thrombosis was identified in 22/264 catheters. The incidence density rate of thrombosis was 5.33 ‰ catheter-days (95 % CI: 3.34-8.07). Cardiovascular surgery and and the use of central catheters others than peripherally inserted ones, were independent risk factors for thrombosis (hazard ratio: 3.8 [95 % CI: 1.6-9] and 2.75 [95 % CI: 1.17-6.45]). CONCLUSIONS: The incidence of central venous catheter-related deep vein thrombosis was 5.33 per 1000 catheter-days. A history of cardiovascular surgical procedures and and the use of central catheters others than peripherally inserted ones, were associated with a higher risk of this complication.

Introducción. En neonatología, más del 90 % de las trombosis venosas profundas están asociadas al uso de catéteres. El objetivo del estudio fue determinar la incidencia y los factores de riesgo relacionados con trombosis venosa profunda asociada a catéteres venosos centrales. Población y métodos. Estudio observacional analítico de cohorte prospectivo. Se incluyeron todos los catéteres venosos centrales mediante un muestreo no aleatorio consecutivo. El protocolo de pesquisa incluyó la evaluación clínica diaria y ecografía doppler (7-10 días luego de su colocación y/o a las 72 h de su retiro). Seguimiento: desde la colocación al retiro del catéter, fallecimiento o contrarreferencia del paciente. Se estimó densidad de incidencia cada 1000 días/catéter con sus intervalos de confianza (IC) del 95 % y factores de riesgo mediante análisis multivariado de Cox. Resultados. Se identificó trombosis en 22/264 catéteres. La densidad de incidencia de trombosis fue del 5,33 ‰ días/catéter (IC 95 %: 3,34-8,07). La cirugía cardiovascular y el uso de catéteres distintos a los epicutáneos resultaron ser factores de riesgo independientes para trombosis [Hazard Ratio: (3,8 [IC 95 %: 1,6-9] y 2,75 [IC 95 %: 1,17-6,45]). Conclusiones. La incidencia de trombosis venosa profunda asociada a catéteres venosos centrales fue de 5,33 cada 1000 días/catéter. El antecedente de procedimientos quirúrgicos cardiovasculares y el uso de catéteres distintos a los epicutáneos se asociaron con mayor riesgo de la complicación.

Utilidad diagnóstica del dímero D cuantitativo / Diagnostic usefulness of quantitative D-dimer

Introducción: El dímero D es un marcador de la generación de trombina y plasmina. Constituye el producto final de la degradación de un trombo rico en fibrina mediada por la acción secuencial de 3 enzimas: trombina, factor FXIIIa y plasmina. Las pruebas disponibles en la actualidad para el diagnóstico del dímero D son variadas y no son uniformes. Objetivo: Analizar las evidencias disponibles sobre la utilidad de diferentes pruebas rápidas de dímero D. Métodos: Se realizó una revisión de la literatura de los últimos diez años, en inglés y español, utilizando motores de búsqueda como Google Académico y Pubmed que permitió el acceso a artículos relacionados en revistas arbitradas. Se agrupó y organizó información sobre las posibles utilidades del dímero D. Desarrollo: La determinación en el laboratorio del dímero D, se usa como prueba rápida y sencilla, posee un lugar definido en los algoritmos de exclusión de la enfermedad tromboembólica venosa, en el diagnóstico de coagulación intravascular diseminada y con aplicación en la predicción de la recidiva de trombosis venosa profunda, en los últimos años. Existen diversos ensayos para la determinación de la concentración plasmática de dímero D que utilizan distintas metodologías, diferentes anticuerpos y sensibilidades. Conclusiones: La determinación de dímero D por los métodos cuantitativos en pacientes con trastornos trombóticos es muy importante para determinar su sensibilidad, y fundamentar el desarrollo del algoritmo diagnóstico de las mencionadas entidades(AU)

Introduction: D-dimer is a marker of thrombin and plasmin generation. It is the final product of the degradation of a fibrin-rich thrombus mediated by the sequential action of three enzymes: thrombin, factor XIIIa and plasmin. The tests currently available for D-dimer diagnosis are varied and not uniform. Objective: Analyze the evidence available about the usefulness of a number of D-dimer rapid tests. Methods: A review was conducted of the literature published in English and Spanish in the last ten years, using search engines such as Google Scholar and PubMed, which allowed access to papers about the topic in peer-reviewed journals. Data about the possible uses of D-dimer were grouped and organized. Discussion: Laboratory D-dimer determination is a rapid and simple test that has occupied a definite place in the exclusion algorithms for venous thromboembolic disease, the diagnosis of disseminated intravascular coagulation, and the prediction of deep venous thrombosis recurrence in recent years. A number of assays are available to determine D-dimer plasma concentration. These are based on different methodologies, antibodies and sensitivity values. Conclusions: D-dimer determination by quantitative methods is very important in patients with thrombotic disorders to determine their sensitivity and substantiate the development of the diagnostic algorithm for the aforementioned conditions(AU)

Upper extremity deep venous thrombosis and pulmonary embolism after transvenous lead replacement or upgrade procedures.

BACKGROUND: Venous obstructions are frequent in patients with transvenous leads, although related clinical findings are rarely reported. After lead replacement or upgrade procedures, these lesions are even more frequent, but there is still no evidence to support this observation. AIM: To investigate the incidence and possible risk factors for upper extremity deep venous thrombosis (UEDVT) and pulmonary embolism (PE) after lead replacement or upgrade procedures. METHODS: Prospective cohort carried out between April 2013 and July 2016. Preoperative evaluation included venous ultrasound and pulmonary angiotomography. Diagnostic exams were repeated postoperatively to detect the study outcomes. Multivariate logistic regression models were used to identify prognostic factors. RESULTS: Among the 84 patients included, 44 (52.4%) were female and mean age was 59.3 ± 15.2 years. Lead malfunctioning (75.0%) was the main surgical procedure indication. Lead removal was performed in 44 (52.4%) cases. The rate of postoperative combined events was 32.6%, with 24 (28.6%) cases of UEDVT and six (7.1%) cases of PE. Clinical manifestations of deep venous thrombosis occurred in 10 (11.9%) patients. Independent prognostic factors for UEDVT were severe collateral circulation in the preoperative venography (odds ratio [OR] 4.7; 95% confidence interval [CI] 1.1-19.8; P = .037) and transvenous lead extraction (OR 27.4; 95% CI 5.8-128.8; P < .0001). CONCLUSION: Reoperations involving previously implanted transvenous leads present high rates of thromboembolic complications. Transvenous lead extraction had a significant impact on the development of UEDVT. These results show the need of further studies to evaluate the role of preventive strategies for this subgroup of patients.

Trombosis venosa profunda en pacientes pos quirúrgicos de cirugías abdominales y ortopedias / Deep venous thrombosis in postoperative patients of abdominal surgeries and orthopedics

La trombosis venosa profunda (TVP) es el común denominador de distintos estados clínicos y patológicos. Estos incluyen, además de la trombosis de las venas, la embolia pulmonar del infarto pulmonar consiguiente. Las lesiones de las venas varían desde trombos localizados en venas pequeñas hasta trombos extensos en venas principales como la vena cava o los troncos íleo femoral. En algunos casos la TVP se debe a una lesión inflamatoria o traumática del endotelio de la pared de la vena, pero en la mayoría no existen antecedentes de enfermedad ni de daño a la vena. La trombosis venosa profunda es una enfermedad silenciosa, de fácil manejo profiláctico, es por ello la importancia de la identificación de sus factores de riesgo, para mediante una rápida acción se logre un manejo adecuado y eficaz que baje los riesgos del paciente y disminuya costos en cuanto al manejo intrahospitalario. En el hospital nacional Rosales, aún no se cuentan con datos de incidencia de esta enfermedad, por lo que se estudiarán los diferentes factores de riesgo y componentes que envuelven a esta enfermedad

Trombosis venosa profunda de miembros superiores asociada a dispositivos intravasculares serie de casos / Deep vein thrombosis of the upper limbs associated with intravascular devices number of cases

El 10% de todos los casos de trombosis venosa profunda afectan a las extremidades superiores. La trombosis venosa profunda de los miembros superiores (TVPMS) es una entidad cada vez más frecuente debido al uso de catéteres venosos centrales (CVC) y de dispositivos transvenosos, como marcapasos y cardiodesfibriladores. Las venas más frecuentemente involucradas son la subclavia y la axilar.

10% of all cases of deep vein thrombosis affect the upper extremities. Deep vein thrombosis of the upper limbs (DVTUL) is an increasingly common entity due to the use of central venous catheters (CVC) and transvenous devices, such as pacemakers and cardio-defibrillators. The most frequently involved veins are the subclavian and the axillary.

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.

[Síndrome de Paget-Schrötter: presentación de cuatro casos]. / Paget-Schrötter syndrome: description of four cases.

Deep vein thrombosis (DVT) of the upper limb is a rare entity, estimated to account for 10% of all cases of DVT. Classically, they are classified into primary (idiopathic, due to subclavian vein compression or exercise related) and secondary (cancer, thrombophilia, trauma, shoulder surgery, associated to venous catheters or due to hormonal causes). The Paget- Schrötter syndrome is a primary thrombosis of the subclavian vein in the subclavian-axillary junction, related either to repetitive movements or to exercise; leading to microtrauma in the endothelium with consequent activation of the coagulation cascade. Clinically, it presents abruptly with pain, edema and feeling of heaviness in the affected limb. The treatment varies from thrombolytics and anticoagulation to surgical intervention, depending on the time of evolution. We present four cases of exercise-related subclavian vein thrombosis.

Síndrome de Paget-Schrötter: presentación de cuatro casos / Paget-Schrötter syndrome: presentation of four cases

La trombosis venosa profunda (TVP) del miembro superior es una entidad poco frecuente, se estima que representa el 10% de todos los casos de TVP. Clásicamente se clasifican en primarias (idiopáticas, por compresión de la vena subclavia o relacionadas con el ejercicio) y secundarias (cáncer, trombofilia, traumatismo, cirugía del hombro, asociadas a catéteres venosos o de causa hormonal). El síndrome de Paget- Schrötter es una trombosis primaria de la vena subclavia en la unión subclavio-axilar, ya sea por movimientos repetitivos o relacionada al ejercicio; llevando a microtrauma en el endotelio con la consiguiente activación de la cascada de coagulación. Clínicamente se presenta de forma brusca con dolor, edema y sensación de pesadez en el miembro afectado. El tratamiento varía desde trombolíticos y anticoagulación a la intervención quirúrgica, dependiendo del tiempo de evolución. Presentamos cuatro casos de trombosis de vena subclavia relacionada con el ejercicio.

Preferred Management of Primary Deep Arm Vein Thrombosis.

OBJECTIVE: Given its rarity, the management of primary upper extremity deep vein thrombosis is controversial. Although anticoagulation alone is commonly advocated for its treatment, it is unclear if this will reduce the risk of developing post-thrombotic syndrome (PTS). The aim of this "Evidence Driven" Clinical Scenario is to evaluate whether more aggressive treatments (including catheter directed thrombolysis or surgery) might help reduce the risk of PTS or recurrent venous thromboembolism in patients with primary upper extremity deep vein thrombosis (DVT). METHODS: An electronic systematic review of Ovid MEDLINE and Embase was conducted. Randomised controlled trials and observational studies were eligible. The primary outcome was PTS. RESULTS: The initial search identified 146 articles, and 36 more were identified during a secondary search. In total, 25 studies, reporting the outcome of 1271 patients, were included. None of the studies included was a randomised controlled trial and the large majority of studies were retrospective cohorts. The use of anticoagulation alone was associated with a significant risk of PTS. In patients treated with surgery with or without thrombolysis the incidence of PTS was significantly reduced. CONCLUSION: Current evidence, albeit with some methodological limitations, suggests that anticoagulation may not be sufficient to prevent PTS in patients with primary upper extremity DVT and that surgery with or without thrombolysis to repair the anatomical defects is needed.

Spontaneous Subclavian Vein Thrombosis in a Healthy Adolescent Cheerleader: A Case of Paget-Schroetter Syndrome.

We present the case of a healthy 13-year-old female adolescent who developed acute progressive swelling and pain in her right upper extremity that was secondary to an acute deep venous thrombosis of her right subclavian vein. Dynamic imaging revealed subclavian vein compression at the junction of the first rib and proximal third of the clavicle consistent with Paget-Schroetter syndrome, also known as effort-related thrombosis. The compressive etiology of her thrombus was most likely related to her cheerleading activity, in which she served as the pyramid base. The patient received multimodal therapy including anticoagulation, mechanical and site-directed thrombolysis, and a first rib resection. This case illustrates that frontline providers should have a high index of suspicion for an upper extremity thrombosis in pediatric patients who present with unilateral arm swelling.

Nuevas consideraciones en el tratamiento del tromboembolismo pulmonar: new considerations in its treatment / Pulmonary tromboembolismo: new considerations in its treatment

La enfermedad tromboembólica tiene altas cifras de morbilidad y mortalidad. Se presenta en un variado espectro de pacientes. Continúa siendo un diagnóstico importante en la atención de las urgencias médicas por lo que hemos decidido realizar esta revisión bibliográfica con el objetivo de actualizar los conocimientos cada vez más necesarios, sobre el diagnóstico y la conducta que se debe asumir en esos casos. Teniendo en cuenta que su diagnóstico por técnicas de imagen es cada vez más difícil, lo que evidencia el valor del método clínico en esta impactante enfermedad, así como su prevención. Sin olvidar que a pesar de estar estandarizada cada conducta, debe valorarse la individualidad del paciente(AU)

Thromboembolic disease has high morbidity and mortality. It comes in a wide spectrum of patients. It remains an important diagnosis in the care of medical emergencies so we decided to do this literature review in order to update the increasingly necessary knowledge about the diagnosis and behavior that must be undertaken in such cases. Given that its diagnostic by imaging is increasingly difficult, the clinical method is valuable in this shocking disease and its prevention. Not to mention that despite being standardized each patient's individuality must be evaluated(AU)

Trombosis venosa profunda masiva de miembro superior secundaria a fractura de clavícula / Thrombose veineuse profonde massive du membre supérieur après une fracture de clavicule / Upper-Extremity Massive Deep Vein Thrombosis Secondary of Broken Collarbone

La trombosis venosa profunda del miembro superior es una entidad rara que se asocia con el uso de catéteres, estados de hipercoagulabilidad, anticonceptivos orales, neoplasias, síndrome de costilla cervical o de los escalenos, fracturas de clavícula y trombosis inducida por el esfuerzo. Se presenta un paciente de 53 años, del sexo masculino que desarrolló una trombosis de las venas axilar, cefálica y basílica tres días después de sufrir una fractura de tercio medio de clavícula que se inmovilizó inicialmente con vendaje en 8. El cuadro se resolvió con tratamiento con tinzaparina sódica y rehabilitación funcional; la fractura de clavícula consolidó y se recanalizaron las venas trombosadas. Se han reportado algunos casos de trombosis de las venas axilar o subclavia ocasionada por fracturas claviculares. Es muy infrecuente la aparición de trombosis extensa afectando a varias venas, en este caso, secundaria al traumatismo o a la presión ejercida por el vendaje(AU)

Upper-extremity deep vein thrombosis is a rare entity that is associated with the use of catheters, hypercoagulable states, oral contraceptives, neoplasias, cervical rib or scalene syndrome, clavicle fractures and stress induced thrombosis. A 53 year male patient is presented here. He developed thrombosis of the axillary, cephalic and basilica veins three days after suffering a fractured middle third clavicle, which was initially immobilized with eight-bandage. The condition was solved with enoxaparin sodium and functional rehabilitation; clavicle fracture consolidated and thrombosed veins had recanalization. Some cases of thrombosis of the axillary or subclavian veins caused by clavicular fractures have been reported. It is very rare the occurrence of extensive thromboses affecting several veins, in this case, secondary to trauma or pressure exerted by the bandage(AU)

La thrombose veineuse profonde du membre supérieur est une affection rare liée à l'usage de canules, à l'hypercoagulabilité, aux contraceptifs oraux, aux néoplasies, au syndrome de la côte cervicale ou du scalène antérieur, aux fractures de clavicule et à la thrombose induite par l'effort. Un patient âgé de 53 ans, ayant souffert une thrombose des veines axillaire, céphalique et basilique trois jours après une fracture du tiers moyen de clavicule et étant immobilisé au début par un bandage en forme de 8, est présenté. Le traitement a consisté à l'administration de tinzaparine sodique et la réhabilitation fonctionnelle ; la fracture de clavicule a consolidé et les veines affectées par la thrombose ont été récanalisées. Quelques cas de thrombose de la veine axillaire ou sous-clavière provoquée par des fractures claviculaires ont été rapportés. La survenue d'une thrombose étendue affectant plusieurs veines, dans ce cas après un traumatisme ou une pression exercée par un bandage, est très peu fréquente(AU)
