Efecto de un equipo multidisciplinar (código TEP) en el pronóstico de los pacientes con tromboembolia de pulmón aguda sintomática / Impact of a pulmonary embolism response team (PERT) in the prognosis of patients with acute symptomatic pulmonary embolism

Antecedentes No se han aclarado suficientemente los beneficios del manejo multidisciplinar (código TEP) de los pacientes con tromboembolia de pulmón (TEP) aguda sintomática. El objetivo de este estudio fue evaluar el efecto sobre la mortalidad a corto plazo del código TEP comparado con la atención habitual. Métodos Realizamos un estudio retrospectivo que incluyó a todos los pacientes con diagnóstico de TEP aguda sintomática ingresados en un hospital terciario universitario entre los años 2007 y 2022. Mediante un análisis de emparejamiento exacto 1:1, los pacientes atendidos por un equipo multidisciplinar para el manejo de la TEP (código TEP) fueron emparejados con otros que recibieron la atención habitual (es decir, no multidisciplinar) para la TEP. El evento primario de eficacia fue la mortalidad por cualquier causa durante los 30 primeros días después del diagnóstico. El evento secundario de eficacia fue la mortalidad por la propia TEP durante el mismo período de tiempo. Resultados De los 2.902 pacientes con diagnóstico de TEP aguda sintomática incluidos en este estudio, 223 (7,7%; intervalo de confianza [IC] del 95%: 6,7-8,7%) fueron manejados por el código TEP. Se emparejaron 207 pacientes manejados por el código TEP con 207 pacientes manejados de forma habitual. En la cohorte emparejada, la atención multidisciplinar a los pacientes con TEP aguda sintomática no se asoció a una reducción significativa de la mortalidad por cualquier causa (odds ratio [OR]: 1,09; IC del 95%: 0,63-1,89) o por la propia TEP (OR: 1,30; IC del 95%: 0,47-3,62) en el mes posterior al diagnóstico de la TEP. Conclusiones La atención multidisciplinar a los pacientes con TEP aguda sintomática no se asoció a una reducción significativa de la mortalidad precoz. (AU)

Background The effect of a pulmonary embolism response team (PERT) in the short-term prognosis of patients with acute symptomatic pulmonary embolism (PE) lacks clarity. We therefore aimed at evaluating the effect of a PERT team on short-term mortality among patients with acute PE. Methods We retrospectively reviewed consecutive patients with acute symptomatic PE enrolled in a single-center registry between 2007 and 2022. We used propensity score matching to compare treatment effects for patients with similar predicted probabilities of receiving management by the PERT team. The primary outcome was all-cause mortality within 30 days following the diagnosis of PE. The secondary outcome was 30-day PE-related mortality. Results Of the 2,902 eligible patients who had acute symptomatic PE, 223 (7.7%; 95% confidence interval [CI], 6.7%-8.7%) were managed by the PERT team. Two hundred and seven patients who were treated by the PERT were matched with 207 patients who were not. Matched pairs did not show a statistically significant lower all-cause (odds ratio [OR], 1.09; 95% CI, 0.63-1.89) or PE-related death (OR, 1.30; 95% CI, 0.47-3.62) for PERT management compared with no PERT management through 30 days after diagnosis of PE. Conclusions Our results suggest that multidisciplinary care of patients with acute symptomatic PE by a PERT team is not associated with a significant reduction in short-term all-cause or PE-related mortality.

Aim: to compare the frequency of acute thromboembolic events in patients visited in the casualty department of a regional hospital during the first few weeks of the COVID-19 pandemic in 2020 with the same period of previous year.Material and methods: retrospective study of patients aged over 40 years of age treated in the casualty department of Hospital de Riotinto (Huelva) from 15 March to 30 April 2019 and same period of 2020. The information was collected from a review of medical records. The data collection questionnaire contained clinical and sociodemographic variables.Results: a total of 1245 patients were included. Mean age was 71.2 (SD:13.7) years old and 51.1% were women. In 2019, 797 patients aged over 40 years of age were treated, while in 2020, the patients seen were 448, which represented a decrease of 43.79%. The prevalence of pulmonary embolism was higher in 2020 compared to 2019 (1.6% vs. 0.4%; P=0.024). The frequency of venous thrombotic events was also higher in 2020 compared to 2019 (1.35% vs. 0.4%; P=0.054). The overall prevalence of venous thromboembolic disease with composite variable (pulmonary thromboembolism + venous thrombosis) was statistically significantly higher in 2020 versus 2019 (2.9% versus 0.8%; P=0.003). None of our patients were diagnosed with COVID-19 and thromboembolism.Conclusions: during the period of confinement during the pandemic there was an increase in the number of acute thromboembolic events in adults, both PE and VTE compared to the previous year.(AU)

[Translated article] Risk of venous thromboembolism in thromboprophylaxis between aspirin and low molecular weight heparins after total hip arthroplasty or total knee arthroplasty: Systematic review and meta-analysis.

INTRODUCTION: The aim of this study was to evaluate the efficacy of aspirin versus low molecular weight heparins (LMWH) for the prophylaxis of venous thromboembolism (VTE), deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing total knee arthroplasty (TKA) and/or total hip arthroplasty (THA). MATERIALS AND METHODS: Systematic review and meta-analysis. Sixteen studies were selected. The risk of VTE, DVT and PE were analysed. Mortality, risk of bleeding and surgical wound complications was also analysed. RESULTS: 248,461 patients were included. 176,406 patients with thromboprophylaxis with LMWH and 72,055 patients with aspirin thromboprophylaxis. There were no significant differences in the risk of VTE (OR=0.93; 95% CI: 0.69-1.26; p=0.64), DVT (OR=0.72; 95% CI: 0.43-1.20; p=0.21) or PE (OR=1.13; 95% CI: 0.86-1.49; p=0.38) between both groups. No significant differences were found in mortality (p=0.30), bleeding (p=0.22), or complications in the surgical wound (p=0.85) between both groups. These same findings were found in the sub-analysis of only randomised clinical trials (p>0.05). CONCLUSIONS: No increased risk of PE, DVT, or VTE was found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis. There was also no greater mortality, greater bleeding, or greater complications in the surgical wound found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis.

Randomized clinical trial of aspirin as prophylaxis for thromboembolism in hip arthroplasty / Ensaio randomizado da aspirina na profilaxia do tromboembolismo em artroplastia do quadril

ABSTRACT Objective: This study aims to evaluate aspirin as a chemical prophylaxis (200 mg) in total hip arthroplasty. Methods: the study compared two groups and used ultrasonography (USG) to screen for low-deep venous thrombosis. Group 1 received 600 mg (control), and Group 2 received 200 mg of (intervention), associated with the use of elastic compression stockings and early walking Results: fourteen patients were allocated to Group A (200mg), and 16 to Group B (600mg); in group A (200mg), 3 cases with thrombus below the popliteal vein were detected at the first USG examination. All of them are in the left lower limb (21.4%). In group B (600 mg), 5 cases were identified after the first exam (31.2%). All cases were asymptomatic and followed the protocol with prophylaxis only with Aspirin. Conclusion: In the statistical data, there were no differences in the presence of thrombus between the 200- and 600 mg groups, which is credited to using low-dose aspirin in low doses (200mg). Hematimetric levels returned to baseline levels and suggested there was no chronic or acute bleeding related to the use of aspirin. The manuscript was prepared according to the CONSORT guideline 2010. Level of Evidence I; Longitudinal Randomized Comparative Clinical Study.

RESUMO Objetivo: Este estudo pretende avaliar a aspirina como profilaxia química (200 mg) na artroplastia total do quadril. Métodos: estudo comparando dois grupos com diferentes doses de aspirina e utilizando a ultrassonografia (USG) para rastreamento da trombose venosa profunda baixa. O grupo 1, 650 mg ao dia de aspirina (controle) e o grupo 2, 200 mg de aspirina ao dia na mesma posologia (intervenção) e associados ao uso de meias elásticas de compressão e deambulação precoce. Resultados: quatorze pacientes foram alocados no grupo A (200 mg) e 16 no grupo B (650 mg). No grupo A foram detectados 3 casos com trombos abaixo da veia poplítea ao USG sendo 21,4%. Já no grupo B, 5 casos foram identificados após o primeiro exame (31,2%). Todos assintomáticos e sem sinais de sangramento ativo ou queda da hematimetria no momento da detecção dos trombos. Conclusão: os dados sugerem não haver diferença na incidência de trombo em ambos os grupos, não sendo a profilaxia com a aspirina dose-dependente. Os níveis hematimétricos retornaram aos níveis iniciais o que sugere não ter havido sangramento crônico ou agudo relacionado ao uso. Nível de Evidência I; Estudo Clínico Randomizado Longitudinal Comparativo.

Capacidad de diferentes reglas de decisión clínica para descartar tromboembolismo pulmonar en pacientes de 35 o menos años atendidos en servicios de urgencias: análisis post-hoc de tres cohortes prospectivas / Pulmonary embolism rule-out decision-making tools for patients aged 35 years or younger in hospital emergency departments: a post-hoc analysis of performance in 3 prospective cohorts

Objetivos: Evaluar la capacidad de la regla PERC (Pulmonary Embolism Rule-out Criteria) y la regla modificada por edad (PERC-35) para descartar tromboembolia pulmonar (TEP) en servicios de urgencias hospitalarios (SUH) en pacientes # 35 años. El objetivo secundario fue analizar otras reglas de decisión clínica. Método: Análisis post-hoc de 3 estudios de cohorte europeos (PROPER, PERCEPIC y MODIGLIANI). Se incluyeron pacientes # 35 años con sospecha de TEP en SUH y con seguimiento a 3 meses. La seguridad y eficacia de PERC yPERC-35 se evaluaron con su tasa de error -no detectar TEP- y la proporción de pacientes con diagnóstico de TEP descartado. Se evaluó la seguridad y eficacia de las reglas YEARS y PEGeD. Resultados: Se analizaron 1.235 pacientes # 35 años. Hubo 22 (1,8%, IC 95%: 1,2-2,7) TEP diagnosticados a los 3 meses. Hubo 6 (1,0%, IC 95%: 0,5-2,2) y 5 (0,9%, IC 95%: 0,4-2,1) TEP no diagnosticados con las reglas PERC y PERC-35 respectivamente. Estas reglas permitieron descartar TEP en 591 (48,2%, IC 95%: 45,4- 51,0) y 554 (46,2%, IC 95%: 43,4- 49,0) respectivamente. La tasa de error de YEARS y PEGeD fue del 0,4% (IC 95%: 0,1- 1,1) y 0,5% (IC 95%: 0,2-1,2), con una eficacia similar. Conclusiones: En pacientes # 35 años, las reglas PERC y PERC-35 mostraron perfiles de seguridad y eficacia similares. Sin embargo, el amplio intervalo de confianza comunicado en este estudio no permite confirmar su seguridad. (AU)

Objectives: To assess the performance of the Pulmonary Embolism Rule-out Criteria (PERC) and the age-modified PERC-35 tool in hospital emergency departments (EDs) for evaluating patients aged 35 years or younger. A secondary aim was to assess other decision-making criteria. Method: Post-hoc analysis of 3 European cohort studies. We included data for patients aged 35 years or younger suspected of PE who were followed for 3 months. The safety and efficacy of applying the PERC and PERC-35 were assessed with the diagnostic error rate (failure to detect PE) and the proportion of patients in whom a diagnosis of PE was ruled out. We also assessed the safety and efficacy of applying the YEARS and PEGeD criteria. Results: Data for 1235 patients aged 35 years or younger were analyzed. Twenty-two (1.8%; 95% CI, 1.2%-2.7%) PE cases were diagnosed at 3 months. Six (1.0%; 95% CI, 0.5%-2.2%) and 5 (0.9%; 95% CI, 0.4%-2.1%) PE cases were not diagnosed by the PERC and PERC-35 tools, respectively. These tools allowed PE to be ruled out in 591 (48.2%; 95% CI, 45.4%-51.0%) and 554 (46.2%; 95% CI, 43.4%-49.0%) cases, respectively. The error rates of the YEARS and PEGeD criteria, respectively, were 0.4% (95% CI, 0.1%-1.1%) and 0.5% (95% CI, 0.2%-1.2%); their efficacy was similar. Conclusions: The safety and efficacy profiles of the PERC and PERC-35 algorithms were similar in patients aged 35 years or younger. However, the large confidence intervals we report do not allow us to confirm the safety of using the tools in patients in this age group. (AU)

Emergency department management of atrial fibrillation: 2023 consensus from the Spanish Society of Emergency Medicine (SEMES), the Spanish Society of Cardiology (SEC), and the Spanish Society of Thrombosis and Hemostasis (SETH). / Manejo de la fibrilación auricular en los servicios de urgencias hospitalarios: actualización a 2023 del consenso de la Sociedad Española de Medicina de Urgencias (SEMES), la Sociedad Española de Cardiología (SEC) y la Sociedad Española de Trombosis y Hemostasia (SETH).

OBJECTIVES: Atrial fibrillation (AF) is the most prevalent sustained arrhythmia managed in emergency departments, and the already high prevalence of this arrhythmia is increasing in Spain. This serious condition associated with increased mortality and morbidity has a negative impact on patient quality of life and the functioning of the health care system. The management of AF requires consideration of diverse clinical variables and a large number of possible therapeutic approaches, justifying action plans to coordinate the work of several medical specialties in the interest of providing appropriate care and optimizing resources. This consensus statement brings together recommendations for emergency department management of AF based on available evidence adapted to special circumstances. The statement was drafted by a multidisciplinary team of specialists from the Spanish Society of Emergency Medicine (SEMES), the Spanish Society of Cardiology (SEC), and the Spanish Society of Thrombosis and Hemostasis (SETH). Strategies for stroke prophylaxis, measures to bring heart rate and heart rhythm under control, and related diagnostic and logistic issues are discussed in detail.

OBJETIVO: La fibrilación auricular (FA) es la arritmia sostenida de mayor prevalencia en los servicios de urgencias (SU), y en España presenta una frecuentación elevada y creciente. Esta arritmia es una enfermedad grave, que incrementa la mortalidad y asocia una relevante morbilidad e impacto en la calidad de vida de los pacientes y en el funcionamiento de los servicios sanitarios. La diversidad de aspectos clínicos a considerar y el elevado número de opciones terapéuticas posibles justifican la implementación de estrategias de actuación coordinadas entre los diversos profesionales implicados, con el fin de incrementar la adecuación del tratamiento y optimizar el uso de recursos. Este documento, realizado por un grupo multidisciplinario de expertos en arritmias cardiacas miembros de la Sociedad Española de Medicina de Urgencias y Emergencias, la Sociedad Española de Cardiología y la Sociedad Española de Trombosis y Hemostasia, recoge las recomendaciones para el manejo de la FA en los SU hospitalarios, basadas en la evidencia disponible y adaptadas a las especiales circunstancias de los mismos. En él se analizan con detalle las estrategias de profilaxis tromboembólica, control de frecuencia y control del ritmo, y los aspectos logísticos y diagnósticos relacionados.

Diferencias de sexo en los beneficios de la anticoagulación en pacientes ancianos con fibrilación auricular: un subanálisis del estudio EMERG-AF / Sex-related differences in benefits of anticoagulation therapy in elderly patients with atrial fibrillation: a subanalysis of the EMERG-AF study

Objetivos: Analizar los beneficios y seguridad a largo plazo de la anticoagulación oral (ACO) prescrita en los servicios de urgencias (SU) a pacientes mayores con fibrilación auricular (FA) y las diferencias en función del sexo. Método: Se trata de un análisis post-hoc del estudio EMERG-AF. Se incluyeron pacientes consecutivos $ 75 años, que consultaron en 62 SU por FA. Se recogieron datos clínicos y ACO. La variable principal estuvo compuesta por muerte, tromboembolia o sangrado mayor en 1 año. Resultados: Se incluyeron 690 pacientes, 386 mujeres (55,9%). Al alta, 575 pacientes (83,3%) estaban con ACO. En 96 de ellos se inició en el SU. Tras 1 año, la variable principal sucedió en 158 pacientes (22,9%): 118 (17,1%) fallecieron, 22 (2,7%) tuvieron una complicación tromboembólica y 34 (4,9%) una hemorragia mayor. Tras ajustar por las principales características clínicas, la ACO se asoció a una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p < 0,001), pero no se asoció con la hemorragia mayor. En las mujeres, la ACO se asoció con una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p < 0,001) y una menor mortalidad (HR: 0,281, IC 95%: 0,168-0,469, p < 0,001), incluidos pacientes con nueva prescripción y en aquellos dados de alta. Esta asociación no alcanzó significación en los hombres. (AU)

Objectives: To analyze the long-term benefits and safety of oral anticoagulation therapy prescribed in emergency departments for elderly patients with atrial fibrillation, and to detect any sex-related differences present. Material and methods: Post-hoc analysis of data compiled by the EMERG-AF group (Spanish acronym for Emergency Department Stroke Prophylaxis and Guidelines Implementation in Atrial Fibrillation). Consecutive patients aged 75 years or older with atrial fibrillation who were treated in 62 EDs were included. We recorded clinical data and anticoagulants prescribed. Patients were followed for 1 year. The main outcome variable was a composite of death, thromboembolism, or major bleeding within 1 year. Results: Data for 690 patients were registered; 386 (55.9%) were women. At discharge, 575 patients (83.3%) were on anticoagulants; therapy was started in the ED for 96 of them. A total of 158 patients (22.9%) had experienced at least 1 component of the main outcome within 1 year: 118 (17.1%) died, 22 (2.7%) had thromboembolic complications, and 34 (4.9%) had major bleeding. After adjustment for main clinical characteristics, hazard ratios (HRs) showed that anticoagulation therapy was associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) but not specifically with major bleeding overall. When data for women were analyzed separately, anticoagulant therapy was again associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) and also with death (HR, 0.281; 95% CI, 0.168-0.469; P .001), even in patients with anticoagulant prescriptions initiated on discharge from the ED. These associations did not reach statistical significance in men. (AU)

Deep Vein Thrombosis after a Supracondylar Fracture of the Humerus in a Child - A Rare Complication / Trombose venosa profunda após uma fratura supracondilar do úmero em uma criança - Uma complicação rara

Abstract Deep vein thrombosis in the upper extremities is uncommon, especially in the pediatric population and in the trauma setting. The diagnosis is challenging, due to its rarity, requiring a high degree of suspicion. We describe a rare case of humeral vein thrombosis after a displaced supracondylar fracture of the humerus in a 7-year-old girl. The risk factors for thromboembolism and sequelae are also discussed. The early detection and treatment are mandatory to prevent poor outcomes, such as fatal thromboembolism.

Resumo Trombose venosa profunda nas extremidades superiores é incomum, especialmente na população pediátrica e no ambiente do trauma. O diagnóstico é desafiador, devido a sua raridade, exigindo alto grau de suspeita. Descrevemos um caso raro de trombose venosa úmera após uma fratura supracondilar deslocada do úmero em uma menina de 7 anos. Os fatores de risco para tromboembolismo e sequelas também são discutidos. A detecção e o tratamento precoces são obrigatórios para evitar desfechos ruins, como tromboembolismo fatal.

RESULTS: Data for 690 patients were registered; 386 (55.9%) were women. At discharge, 575 patients (83.3%) were on anticoagulants; therapy was started in the ED for 96 of them. A total of 158 patients (22.9%) had experienced at least 1 component of the main outcome within 1 year: 118 (17.1%) died, 22 (2.7%) had thromboembolic complications, and 34 (4.9%) had major bleeding. After adjustment for main clinical characteristics, hazard ratios (HRs) showed that anticoagulation therapy was associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) but not specifically with major bleeding overall. When data for women were analyzed separately, anticoagulant therapy was again associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) and also with death (HR, 0.281; 95% CI, 0.168-0.469; P .001), even in patients with anticoagulant prescriptions initiated on discharge from the ED. These associations did not reach statistical significance in men. CONCLUSION: ED anticoagulant prescription for elderly patients with atrial fibrillation is safe and contributes to a reduction in mortality. Women in this age group benefited more than men from starting anticoagulation during the acute phase in the ED.

OBJETIVO: Analizar los beneficios y seguridad a largo plazo de la anticoagulación oral (ACO) prescrita en los servicios de urgencias (SU) a pacientes mayores con fibrilación auricular (FA) y las diferencias en función del sexo. METODO: Se trata de un análisis post-hoc del estudio EMERG-AF. Se incluyeron pacientes consecutivos $ 75 años, que consultaron en 62 SU por FA. Se recogieron datos clínicos y ACO. La variable principal estuvo compuesta por muerte, tromboembolia o sangrado mayor en 1 año. RESULTADOS: Se incluyeron 690 pacientes, 386 mujeres (55,9%). Al alta, 575 pacientes (83,3%) estaban con ACO. En 96 de ellos se inició en el SU. Tras 1 año, la variable principal sucedió en 158 pacientes (22,9%): 118 (17,1%) fallecieron, 22 (2,7%) tuvieron una complicación tromboembólica y 34 (4,9%) una hemorragia mayor. Tras ajustar por las principales características clínicas, la ACO se asoció a una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p 0,001), pero no se asoció con la hemorragia mayor. En las mujeres, la ACO se asoció con una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p 0,001) y una menor mortalidad (HR: 0,281, IC 95%: 0,168-0,469, p 0,001), incluidos pacientes con nueva prescripción y en aquellos dados de alta. Esta asociación no alcanzó significación en los hombres. CONCLUSIONES: La prescripción de ACO en los SU a pacientes mayores con FA es segura y contribuye a reducir la mortalidad. En este grupo etario, las mujeres se benefician más que los hombres de iniciar la ACO en la fase aguda.

Tromboembolia pulmonar masiva en un paciente con enfermedad de Crohn y tuberculosis latente tratada con ustekinumab

La enfermedad inflamatoria intestinal (EII) es un espectro de enfermedades crónicas inmunomediadas que afectan tanto el tracto gastrointestinal, como otros sistemas extraintestinales, comportándose como una enfermedad sistémica. Los fenómenos tromboembólicos son una complicación frecuente en la EII, como consecuencia de los estados de hipercoagulabilidad que se asocian con la actividad de la enfermedad, y su aparición tiene un impacto negativo tanto en el pronóstico como en la sobrevida de los pacientes. Debido a ello, el control de la actividad inflamatoria de la EII es uno de los pilares en el control de los eventos tromboembólicos. Los medicamentos biológicos se asocian al control rápido del cuadro inflamatorio, sin embargo, siempre se discute el tema de seguridad para la reactivación de infecciones latentes, en particular tuberculosis. Presentamos el caso de un paciente de 37 años que debutó con trombosis venosa profunda en el miembro inferior izquierdo y posteriormente con tromboembolismo pulmonar masivo. Luego de investigar la etiología y ampliar la historia clínica se le diagnosticó Enfermedad de Crohn (EC). Al realizar los estudios previos al uso de biológicos, las pruebas de PPD y quantiferon resultaron positivas, luego de la discusión del caso se decidió iniciar tratamiento con ustekinumab.

Inflammatory bowel disease (IBD) is a spectrum of chronic immune-mediated diseases that affect the gastrointestinal tract and other extraintestinal systems, behaving as a systemic disease. Thromboembolic phenomena are a frequent complication in IBD, because of hypercoagulability states associated with disease activity, and their presence has a negative impact on prognosis and patient survival. Due to this, the control of the inflammatory activity of IBD is one of the pillars in the control of thromboembolic events. Biological drugs are associated with rapid control of the inflammatory process, however, the security profile for the reactivation of latent infections, particularly tuberculosis, is always discussed. We present the case of a 37-year-old patient who presented with deep vein thrombosis in the left lower limb and later with massive pulmonary thromboembolism. During his evaluation, he was diagnosed with Crohn's disease (CD). When carrying out the studies prior to the use of biologics, PPD and quantiferon tests were positive. After discussing the case, we decided to start treatment with ustekinumab.

Pulmonary CT angiography in the first wave of the COVID-19 pandemic: Comparison between patients with and without infection and with a pre-pandemic series.

BACKGROUND AND AIMS: To analyze the diagnostic performance of pulmonary CT angiography and to compare different D-dimer cutoffs for the diagnosis of acute pulmonary embolism in patients with and without SARS-CoV-2 infections. MATERIALS AND METHODS: We retrospectively analysed all consecutive pulmonary CT angiography studies done for suspected pulmonary embolism in a tertiary hospital during two time periods: the first December 2020 through February 2021 and the second December 2017 through February 2018. D-dimer levels were obtained less than 24 h before the pulmonary CT angiography studies. We analysed the sensitivity, specificity, positive and negative predictive values, area under the receiver operating curve (AUC), and pattern of pulmonary embolism for six different values of D-dimer and the extent of the embolism. During the pandemic period, we also analysed whether the patients had COVID-19. RESULTS: After excluding 29 poor-quality studies, 492 studies were analysed; 352 of these were done during the pandemic, 180 in patients with COVID-19 and 172 in patients without COVID-19. The absolute frequency of pulmonary embolism diagnosed was higher during the pandemic period (34 cases during the prior period and 85 during the pandemic; 47 of these patients had COVID-19). No significant differences were found in comparing the AUCs for the D-dimer values. The optimum values calculated for the receiver operating characteristic curves differed between patients with COVID-19 (2200 mcg/l), without COVID-19 (4800 mcg/l), and diagnosed in the prepandemic period (3200 mcg/l). Peripheral distribution of the emboli was more common in patients with COVID-19 (72%) than in those without COVID-19 and than in those diagnosed before the pandemic [OR 6.6, 95% CI: 1.5-24.6, p < 0.05 when compared to central distribution]. CONCLUSIONS: The number of CT angiography studies and the number of pulmonary embolisms diagnosed during the pandemic increased due to SARS-CoV-2 infection. The optimal d-dimer cutoffs and the distribution of the pulmonary embolisms differed between the groups of patients with and without COVID-19.

Difficult withdrawal of an inferior vena cava filter: Technical considerations and associated variables.

OBJECTIVE: To analyse the efficacy of the procedure for withdrawing an inferior vena cava (IVC) filter and the clinical and radiological factors associated with difficult withdrawal. MATERIAL AND METHODS: This retrospective observational study included patients who underwent IVC filter withdrawal at a single centre between May 2015 and May 2021. We recorded demographic, clinical, procedural, and radiological variables: type of IVC filter, angle with the IVC > 15°, hook against the wall, and legs embedded in the IVC wall > 3 mm. The efficacy variables were fluoroscopy time, success of IVC filter withdrawal, and number of attempts to withdraw the filter. The safety variables were complications, surgical removal, and mortality. The main variable was difficult withdrawal, defined as more than 5 min fluoroscopy or more than 1 attempt at withdrawal. RESULTS: A total of 109 patients were included; withdrawal was considered difficult in 54 (49.5%). Three radiological variables were more common in the difficult withdrawal group: hook against the wall (33.3% vs. 9.1%; p = 0.027), embedded legs (20.4% vs. 3.6%; p = 0.008), and >45 days since IVC filter placement (51.9% vs. 25.5%; p = 0.006). These variables remained significant in the subgroup of patients with OptEase IVC filters; however, in the group of patients with Celect IVC filters, only the inclination of the IVC filter >15 ° was significantly associated with difficult withdrawal (25% vs 0%; p = 0.029). CONCLUSION: Difficult withdrawal was associated with time from IVC placement, embedded legs, and contact between the hook and the wall. The analysis of the subgroups of patients with different types of IVC filters found that these variables remained significant in those with OptEase filters; however, in those with cone-shaped devices (Celect), the inclination of the IVC filter >15° was significantly associated with difficult withdrawal.

Angio-TC pulmonar durante la pandemia de COVID-19: comparación en pacientes con y sin la infección y con una serie prepandémica / Pulmonary CT angiography in the first wave of the COVID-19 pandemic: comparison between patients with and without infection and with a pre-pandemic series

Antecedentes y objetivo: Analizar el rendimiento diagnóstico de la angio-TC pulmonar y comparar distintos valores de corte del dímero-D para el diagnóstico de tromboembolia pulmonar (TEP) aguda en pacientes con y sin infección por SARS-CoV-2.Materiales y métodos: Análisis retrospectivo de todas las angio-TC pulmonares realizadas consecutivamente por sospecha de TEP en un hospital de tercer nivel durante 2 periodos distintos. El primero de diciembre del 2020 a febrero del 2021 y el segundo de diciembre del 2017 a febrero del 2018. Se recogieron los resultados del dímero-D durante las 24h previas a la realización de las angio-TC pulmonares, así como el resultado de estas últimas para todos los pacientes incluidos. Se analizaron la sensibilidad, especificidad, valores predictivos, área bajo la curva (AUC) y patrón de tromboembolia para 6 valores distintos del dímero-D y la extensión del tromboembolia. Durante el periodo de la pandemia se registró si los pacientes tenían enfermedad por SARS-CoV-2. Resultados: Tras desestimar 29 estudios de baja calidad, se incluyeron 492 para el análisis. De ellos, 352 fueron realizados durante la pandemia; 180 en enfermos con COVID-19 y 172 sin la enfermedad. La frecuencia absoluta de TEP diagnosticados durante la pandemia fue mayor (34 durante el periodo previo a la pandemia y 85 durante la pandemia, correspondiendo 47 de este último grupo a pacientes con COVID-19). No se encontraron diferencias significativas al comparar el AUC para los valores del dímero-D. Los valores óptimos calculados a partir de las curvas ROC fueron distintos (2.200, 4.800 y 3.200μg/l en pacientes con COVID-19, sin COVID-19 y en diagnosticados durante el periodo prepandemia, respectivamente).(AU)

Retirada difícil de filtro de vena cava inferior (FVCI). Consideraciones técnicas y variables asociadas / Difficult withdrawal of an inferior vena cava filter: technical considerations and associated variables

Objetivo: Analizar la eficacia del procedimiento de retirada de los filtros de la vena cava inferior (FVCI), así como los factores clínico-radiológicos asociados a una retirada difícil. Material y método: Estudio retrospectivo, observacional y unicéntrico de pacientes tratados mediante retirada de FVCI entre mayo del 2015 y mayo del 2021. Se recogieron variables clínico-demográficas, del procedimiento y radiológicas: tipo de FVCI, angulación respecto a la vena cava inferior (VCI) >15°, gancho contra la pared y patas del dispositivo incrustadas en la pared de VCI> 3mm. Las variables de eficacia fueron: tiempo de fluoroscopia, éxito en la retirada del FVCI y número de intentos hasta la retirada. Como variables de seguridad: presencia de complicaciones, retirada quirúrgica y mortalidad. La variable principal fue la retirada difícil, definida como más de 5min de fluoroscopia o más de un intento de retirada. Resultados: Se incluyó a 109 pacientes, 54 (49,5%) fueron considerados retirada difícil. Las variables radiológicas gancho contra la pared (33,3% vs. 9,1%; p=0,027), patas incrustadas (20,4% vs. 3,6%; p=0,008) y> 45 días desde la colocación (51,9% vs. 25,5%; p=0,006) fueron significativamente más frecuentes en el grupo de retirada difícil. Estas variables mantienen la asociación al analizar los FVCI Optease®. En los FVCI Celect® solo se asoció con retirada difícil la inclinación del FVCI> 15° (25% vs. 0%; p=0,029).Conclusión: Se ha encontrado asociación entre una retirada difícil y las siguientes variables: tiempo desde colocación del FVCI, patas incrustadas y contacto del gancho con la pared de VCI. Al analizar según el tipo de FVCI, estas variables se mantienen en el tipo Optease®, en cambio, la inclinación de más de 15° dificulta la retirada de los dispositivos de morfología cónica (Celect®).(AU)

Riesgo de recurrencia de la trombosis en pacientes con tromboembolia venosa asociada a COVID-19 y a cirugía / Risk of thrombosis recurrence among patients with COVID-19- and surgery-associated venous thromboembolism

Introducción La cirugía reciente es un factor de riesgo transitorio mayor y conocido de tromboembolia venosa (TEV) debido al bajo riesgo de recurrencia de la TEV una vez suspendida la anticoagulación. Por otro lado, se desconoce el riesgo de recurrencia de la TEV en los pacientes con TEV asociada a COVID-19. El objetivo de este estudio consistió en comparar el riesgo de recurrencia de la TEV entre pacientes con TEV asociada a COVID-19 y a cirugía. Método Se realizó un estudio prospectivo, observacional y unicéntrico en el que participaron pacientes consecutivos diagnosticados de TEV en un hospital terciario entre enero de 2020 y mayo de 2022 y que fueron objeto de seguimiento durante un mínimo de 90 días. Se evaluaron las características iniciales, el cuadro clínico y los resultados clínicos. Se compararon las incidencias de recurrencia de la TEV, hemorragias y muertes entre ambos grupos. Resultado En el estudio se incluyó a un total de 344 pacientes: 111 con TEV asociada a cirugía y 233 con TEV asociada a COVID-19. Entre los pacientes con TEV asociada a COVID-19 hubo una mayor frecuencia de varones (65,7 vs. 48,6%, p = 0,003). La recurrencia de la TEV fue de 3% en los pacientes con COVID-19 y de 5,4% en los pacientes quirúrgicos, sin diferencias significativas (p = 0,364). La tasa de incidencia de TEV recurrente fue de 1,25 y 2,29 por 1.000 personas-meses en los pacientes con COVID-19 y quirúrgicos, respectivamente, sin diferencias significativas (p = 0,29). En el análisis multifactorial, la COVID-19 se asoció a una mayor mortalidad (HR = 2,34; IC 95%, 1,19-4,58), pero no a un mayor riesgo de recurrencia (HR = 0,52; IC 95%, 0,17-1,61). En el análisis multifactorial de riesgos competitivos no se observaron diferencias en cuanto a recurrencias (SHR = 0,82; IC 95%, 0,40-2,05). Conclusiones El riesgo de recurrencia fue bajo en los pacientes con TEV asociada a COVID-19 y a cirugía, sin diferencias entre ambos grupos (AU)

Introduction Recent surgery is a well-known major transient risk factor for venous thromboembolism (VTE) due to the low risk of VTE recurrence after anticoagulation is discontinued. On the other hand, the risk of VTE recurrence among patients with COVID-19-associated VTE is unknown. This study aimed to compare the risk of VTE recurrence between patients with COVID-19- and surgery-associated VTE. Methods A prospective observational single-center study was performed including consecutive patients diagnosed with VTE in a tertiary hospital from January 2020 to May 2022 and followed up for at least 90 days. Baseline characteristics, clinical presentation, and outcomes were assessed. The incidence of VTE recurrence, bleeding, and death was compared between both groups. Result A total of 344 patients were included in the study: 111 patients with surgery-associated VTE and 233 patients with COVID-19-associated VTE. Patients with COVID-19-associated VTE were more frequently men (65.7% vs 48.6%, p = 0.003). VTE recurrence was 3% among COVID-19 patients and 5.4% among surgical patients, with no significant differences (p = 0.364). The incidence rate of recurrent VTE was 1.25 per 1000 person-months in COVID-19 patients and 2.29 person-months in surgical patients, without significant differences (p = 0.29). In the multivariate analysis, COVID-19 was associated with higher mortality (HR 2.34; 95% CI 1.19-4.58), but not with a higher risk of recurrence (HR 0.52; 95% CI 0.17-1.61). No differences were found in recurrence in the multivariate competing risk analysis (SHR 0.82; 95% CI 0.40 – 2.05). Conclusions In patients with COVID-19 and surgery-associated VTE, the risk of recurrence was low, with no differences between both groups (AU)

Complicaciones hemorrágicas y trombóticas del embarazo: diagnóstico, prevención y tratamiento

Las hemorragias y la enfermedad tromboembólica venosa (ETEV) figuran entre las cinco causas más frecuentes de morbilidad y mortalidad materna en el mundo. Revisamos la evaluación y el manejo actualizado de las causas obstétricas de la hemorragia posparto (HPP), así como el diagnóstico y manejo de condiciones hematológicas que pueden causar o agravar la HPP, por ejemplo: coagulación intravascular diseminada, enfermedad de von Willebrand, trombocitopenia autoinmune y las microangiopatías trombóticas. Revisamos el rol del síndrome antifosfolípido y las trombofilias hereditarias como factores predisponentes a pérdidas fetales recurrentes y la ETEV en el embarazo y las recomendaciones actuales para la prevención de ambas complicaciones. Asimismo, repasamos el abordaje diagnóstico y líneas de manejo de la ETEV. Un objetivo adicional fue enfatizar la importancia del trabajo colaborativo multidisciplinario para lograr el manejo exitoso de las gestantes con las complicaciones obstétricas y hematológicas descritas.

Bleeding and venous thromboembolism (VTE) are among the five most common causes of morbidity and mortality in pregnant women worldwide. This review describes the current evaluation and management of the obstetric causes of postpartum hemorrhage (PPH), as well as the diagnosis and management of hematologic conditions which can cause or worsen PPH, such as disseminated intravascular coagulation, von Willebrand disease, autoimmune thrombocytopenia and the thrombotic microangiopathies. It also describes the role of the antiphospholipid syndrome and inherited thrombophilia as predisposing factors for recurrent pregnancy loses and VTE, and the current recommendations for the prevention of both complications. As well, the current diagnostic approach and management of ETEV are described. An additional objective of this Review is to emphasize the importance of a collaborative multidisciplinary approach for the successful management of the obstetric and hematologic complications herein described.
