Trombosis venosa de sitio inusual: síndrome de Paget-Schroetter / Venous thrombosis of unusual site: Paget-Schroetter syndrome

RESUMEN Fundamento: la enfermedad tromboembólica venosa es una enfermedad clínica frecuente, asociada a múltiples factores de riesgo ya identificados. Existen presentaciones con localizaciones atípicas, como lo es la trombosis en miembro superior. Al ser su etiología en el 30 % de los casos la hipertrofia de músculos de la cintura escapular (síndrome de Paget-Schroetter), el cual siempre deberá ser sospechado en pacientes sanos que realicen actividades deportivas de máximo esfuerzo donde tanto el tratamiento farmacológico como quirúrgico ofrecerán una adecuada alternativa terapéutica. Objetivo: presentar un paciente joven con trombosis venosa de sitio inusual en miembro superior. Presentación del caso: se presenta el caso de un paciente joven de 20 años sano, deportista de alto rendimiento, quien acude a consulta por cuadro subagudo de signos inflamatorios y circulación colateral en miembro superior izquierdo, con posterior confirmación de trombosis venosa de sitio inusual, se descartan causas comunes, trombofilias y luego se confirma la hipertrofia de músculos escalenos como evento precipitante. Dada la duración del cuadro en su inicio es manejado con anticoagulación e intervenido de forma quirúrgica con adecuada respuesta. Conclusiones: la presencia de trombosis venosa de sitio inusual en miembro superior en pacientes jóvenes, sanos y deportistas obliga a sospechar el síndrome de Paget-Schroetter como principal causa, al permitir un adecuado manejo y pronóstico.

ABSTRACT Background: venous thromboembolic disease is a frequent clinical illness, associated with multiple risk factors already identified. There are presentations with atypical locations such as thrombosis in the upper limb. The etiology in the 30% of cases is the hypertrophy of the scapular waist muscles (Paget-Schroetter syndrome), which should always be suspected in healthy patients that practice sports to their maximum level, where both pharmacological and surgical treatment will offer an adequate alternative. Objective: to present a young patient with venous thrombosis of unusual site in the upper limb. Presentation of the case: we present the case of a 20-year-old healthy patient, previously a high-performance athlete, who went to consultation for a sub-acute symptomps of inflammatory signs and collateral circulation in the left upper limb, with subsequent confirmation of unusual site venous thrombosis. The common etiologies are ruled out and, finally, scalene hypertrophy known as Paget-Schroetter syndrome is confirmed. Given the duration of the symptoms, the anticoagulation is initially handled and subsequently he is surgically treated with an adequate response. Conclusions: the presence of unusual site venous thrombosis in upper limb in young, healthy and athletic patients forces us to be suspicious about the Paget-Schroetter syndrome as the main etiology allowing the correct handling and prognosis.

Catheter-directed thrombolysis for patients with acute lower extremity deep vein thrombosis: a meta-analysis / Trombólise dirigida por cateter para pacientes com trombose venosa profunda aguda das extremidades inferiores: uma metanálise / Trombólisis dirigida por catéter para pacientes con trombosis venosa profunda aguda en las extremidades inferiores: un metanálisis

ABSTRACT Objectives: To evaluate case series studies that quantitatively assess the effects of catheter-directed thrombolysis (CDT) and compare the efficacy of CDT and anticoagulation in patients with acute lower extremity deep vein thrombosis (DVT). Methods: Relevant databases, including PubMed, Embase, Cochrane, Ovid MEDLINE and Scopus, were searched through January 2017. The inclusion criteria were applied to select patients with acute lower extremity DVT treated with CDT or with anticoagulation. In the case series studies, the pooled estimates of efficacy outcomes for patency rate, complete lysis, rethrombosis and post-thrombotic syndrome (PTS) were calculated across the studies. In studies comparing CDT with anticoagulation, summary odds ratios (ORs) were calculated. Results: Twenty-five articles (six comparing CDT with anticoagulation and 19 case series) including 2254 patients met the eligibility criteria. In the case series studies, the pooled results were a patency rate of 0.87 (95% CI: 0.85-0.89), complete lysis 0.58 (95% CI: 0.40-0.75), rethrombosis 0.11 (95% CI: 0.06-0.17) and PTS 0.10 (95% CI: 0.08-0.12). Six studies comparing the efficacy outcomes of CDT and anticoagulation showed that CDT was associated with a reduction of PTS (OR 0.38, 95%CI 0.26-0.55, p<0.0001) and a higher patency rate (OR 4.76, 95%CI 2.14-10.56, p<0.0001). Conclusion: Acute lower extremity DVT patients receiving CDT were found to have a lower incidence of PTS and a higher incidence of patency rate. In our meta-analysis, CDT is shown to be an effective treatment for acute lower extremity DVT patients.

RESUMO Objetivos: Avaliar os estudos de séries de casos e avaliar quantitativamente os efeitos da trombólise dirigida por cateter (TDC) e comparar a eficácia entre TDC e anticoagulação nos pacientes com trombose venosa profunda aguda das extremidades inferiores (TVP) para tratamento futuro. Métodos: Foram pesquisadas as seguintes bases de dados relevantes: PubMed, Embase, Cochrane, Ovid MEDLINE e Scopus​. Os critérios de inclusão foram aplicados para pacientes selecionados com TVP aguda de extremidades inferiores tratados com TDC comparada a TDC com anticoagulação. Nos estudos de série de casos, as estimativas agrupadas de resultados de eficácia para a taxa de permeabilidade, lise completa, retrombose e síndrome pós-trombótica (SPT) foram calculadas em todos os estudos. Em estudos comparando TDC com anticoagulação, foi calculada a razão de chance de resumo (summary odds ratio - OR). Resultados: Vinte e cinco artigos (seis comparando TDC com anticoagulação e 19 séries de casos), incluindo 2.254 pacientes, preencheram os critérios de elegibilidade. Nos estudos da série de casos, os resultados agrupados foram: taxa de permeabilidade 0,87 (IC95%: 0,85-0,89), lise completa 0,58 (IC95%: 0,40-0,75), e retrombose 0,11 (IC95%: 0,06-0,17), SPT 0,10 (IC95%: 0,08-0,12). Seis estudos que compararam os resultados de eficácia entre TDC e anticoagulação mostraram que TDC foi associada à redução da SPT (OR 0,38; IC95%: 0,26-0,55; p<0,0001) e maior taxa de permeabilidade (OR 4,76; IC95%: 2,14-10,56; p<0,0001). Conclusão: Pacientes com TVP aguda de extremidades inferiores que recebem TDC estão associados a uma menor incidência de SPT e maior incidência de taxa de permeabilidade.

Research progress of risk factors of pulmonary thromboembolism / 中国基层医药

Pulmonary embolism is a clinical and pathophysiological syndrome caused by endogenous or exogenous emboli obstructing the pulmonary artery , and its branches causing acute pulmonary circulatory disturbances .Venous thromboembolism is a complex multifactorial disease that involves the interaction of secondary or hereditary thrombosis and various risk factors such as trauma and surgery .With the characteristics of high incidence , misdiagnosis and high mortality ,this study explored the risk factors for pulmonary thromboembolism .Finding its risk factors is the main method to reduce the incidence of pulmonary embolism and reduce the severity of pulmonary embolism.

Reduction mammoplasty as a treatment for symptomatic central venous stenosis

Central venous stenosis is a rare cause of unilateral breast edema occurring in hemodialysis patients that needs to be differentiated from other differential diagnoses, including, but not limited to, inflammatory breast carcinoma, mastitis, lymphedema, and congestive heart failure. All reports of similar cases in the available literature have described improvement or resolution of the edema after treatment. Herein, we report and discuss the pathophysiology of breast edema formation in a patient who presented with massive left-sided breast edema 7 years after being diagnosed with central venous stenosis. Medical and minimally invasive therapy had not been successful, so she underwent reduction mammoplasty to relieve the symptoms.

Management of Venous Thrombosis in Atypical Location / 대한내과학회지

Venous thrombosis in atypical locations means thrombosis of upper extremity deep vein, cerebral venous sinus, splanchnic vein including portal, hepatic, mesenteric and splenic vein, renal vein, ovarian vein and retinal vein. This thrombosis rarely occurred and could be affected by the involved organ when compared to the incidence and cause of deep vein thrombosis in lower extremity with or without pulmonary embolism. There is a limitation to perform a large-scaled randomized trial for these rare conditions, and several recommendations based on results of small-sized studies and observational registries are available now. Therefore, we need multi-department and international collaboration to test the efficacy and safety of anticoagulation including new oral anticoagulants in the treatment of venous thrombosis in atypical locations.

Deep vein thrombosis after spine operation in prone position with subclavian venous catheterization: a case report / 대한마취과학회지

We experienced a case of deep vein thrombosis after spine surgery in the prone position with a central venous catheter (CVC). Posterior lumbar interbody fusion was performed on a 73-year-old female patient who was diagnosed with spinal stenosis. Accordingly, in the operation room under general anesthesia, two-lumen CVC were inserted into the left subclavian vein. The surgery was performed in the prone position with a Wilson frame. On the next day, there was a sudden occurrence of severe edema in the patient's left arm. By ultrasonography and computed tomography scanning, extensive deep vein thrombosis was observed in the left subclavian vein. The existence of a factor affecting blood flow such as the prone position may increase the risk of thrombus formation. Therefore, careful perioperative evaluation should be implemented.

A Case of Upper Extremity Deep Vein Thrombosis and Pulmonary Thromboembolism in a Severely Obese Man / 대한내과학회지

Deep vein thrombosis is a predisposing condition for pulmonary embolism, which can be fatal. Usually, deep vein thrombosis is found in the lower extremities, but it can also occur in the upper extremities. The prevalence of upper extremity deep vein thrombosis appears to be increasing, particularly due to the increased use of indwelling central venous catheters. Pulmonary embolism is present in up to one-third of patients with upper extremity deep vein thrombosis. Upper extremity deep vein thrombosis is an increasingly important clinical entity, with the potential for considerable morbidity. Here, we report a case of upper extremity deep vein thrombosis and pulmonary embolism in a severely obese man who was successfully treated with anticoagulants.

Management of Upper Extremity Deep Vein Thrombosis with a Superior Vena Cava Filter - A Case Report - / 대한구급학회지

Upper extremity deep vein thrombosis (UEDVT) is relatively uncommon and superior vena cava (SVC) filter placements are not often encountered due to strict indication. A 33-year old male with underlying protein C/S deficiency and secondary liver cirrhosis was admitted because of hematemesis. The patient was conservatively managed, but underwent elective splenectomy to prevent aggravation of gastric varix. During postoperative care, the patient underwent cholecystectomy for acalculous cholecystitis. During the postoperative course, UEDVT was detected and heparinization was initiated. The patient experienced repeated attacks of severe dyspnea, which was accompanied by chest pain that lasted for 3 to 10 minutes. Repeated episodes of pulmonary thromboembolism were suspected and SVC filter was placed. Warfarin treatment was initiated and the SVC filter was removed about one month later. The case highlights the clinical significance of UEDVT and reports rare case of SVC filter placement. Intensivists should have comprehensive understanding of UEDVT and its management.

Estudo anatômico da veia braquial comum como via de drenagem colateral do membro superior / Anatomic study of the common brachial vein as a collateral drainage channel of the upper limb

CONTEXTO: Traumatismos ou tromboses que possam evoluir com alterações da drenagem venosa do membro superior, dependendo do território interrompido, podem ter como mecanismo compensatório uma via colateral de drenagem sem que haja prejuízo para o retorno venoso desse membro. A veia braquial comum apresenta-se como uma alternativa plausível e pouco conhecida. OBJETIVO: Descrever a anatomia da veia braquial comum como via de drenagem colateral no membro superior. MÉTODOS: Utilizamos 30 cadáveres do sexo masculino, cujos membros superiores estavam articulados ao tronco, não importando a raça, formolizados e mantidos em conservação com solução de formol a 10 por cento. Utilizamos como critérios de exclusão cadáveres com um dos membros desarticulado ou alterações deformantes em topografia das estruturas estudadas. RESULTADOS: A veia braquial comum esteve presente em 73 por cento (22/30) dos cadáveres estudados, sendo que em 18 por cento (04/22) dos casos drenou para a veia basílica no seguimento proximal do braço e em 82 por cento (18/22), para a veia axilar. CONCLUSÃO: A veia braquial comum está frequentemente presente e, na maior parte das vezes, desemboca na veia axilar.

BACKGROUND: Trauma and thrombosis that can result in changes in the venous drainage of the upper limb, depending on the vascular territory interrupted, may have as a compensatory mechanism a collateral drainage channel that prevents damage to the venous return of that limb. The common brachial vein is a plausible and little known collateral channel for this purpose. OBJECTIVE: To describe the anatomy of the common brachial vein as a collateral drainage channel of the upper limb. METHODS: We have dissected 30 cadavers of people of different races, whose upper limbs were articulated to the trunk and preserved in a 10 percent formaldehyde solution. The exclusion criteria were disarticulated limbs or deformities in the topography of the studied structures. RESULTS: The common brachial vein was present in 73 percent (22/30) of the cadavers dissected. The common brachial vein drained into the axillary vein in 82 percent (18/22) and into the basilic vein in the proximal segment of the upper limb in 18 percent of the cadavers (04/22). CONCLUSION: The common brachial vein is frequently present, and, in most cases, it drains into the axillary vein.

A Case of Trousseau's Syndrome with Catastrophic Course Triggered by an Intravenous Injection / 결핵및호흡기질환

Trousseau's syndrome is an unexplained thrombotic event that precedes the diagnosis of an occult visceral malignancy or appears concomitantly with the tumor. Upper extremity deep vein thrombosis is prevalent in patients with a central venous catheter. Furthermore, a peripheral intravenous injection may cause upper extremity deep vein thrombosis as well. However, a deep vein thrombosis has not been reported in the form of Trousseau's syndrome with a catastrophic clinical course triggered by a single peripheral intravenous injection. A 48-year-old man presented with a swollen left arm on which he was given intravenous fluid at a local clinic due to flu symptoms. Contrast computed tomgraphy scans showed thromboses from the left distal brachial to the innominate vein. The patient developed multiple cerebral infarctions despite anticoagulation treatment. He was diagnosed with stomach cancer by endoscopic biopsy to evaluate melena and had a persistently positive lupus anticoagulant. After recurrent and multiple thromboembolic events occurred with treatment, he died on day 20.
