Thrombotic Event Prevention in Patients Undergoing Posterior Lumbar Arthrodesis: our experiencie. A retrospective case series study. / Prevención de eventos trombóticos en pacientes sometidos a cirugía de artrodesis lumbar por vía posterior: experiencia en nuestro centro. Estudio retrospectivo de casos.

INTRODUCTION: There is no generalized consensus regarding perioperative prophylaxis of venous thromboembolism (VTE), either on using or timing it in patients undergoing spine surgery. VTE is a current concern because, even though being an uncommon event, it can cause serious complications. The aim of the present study is to propose guidelines for the prevention of thrombotic events in posterior spinal surgery, either as deep vein thrombosis or pulmonary thromboembolism. If the number of patients getting prophylaxis drugs is reduced a subsequent reduction of the incidence of epidural hematoma can be expected. MATERIALS AND METHODS: A number of 235 patients who had undergone posterior spinal arthrodesis in the previous five years were studied. Mechanical thromboprophylaxis measures consisting of compression stockings were applied in all of them. Anticoagulant drugs were also applied whenever risk factors for thrombosis were observed. Early weight-bearing was resumed immediately after surgery. Demographic, clinical, and surgical variables were collected, as well as complications appearing during the follow-up period, that was scheduled at one, two, four, six and twelve months after the surgery. Thrombotic events, if present, were diagnosed by clinical and imaging tests such as ultrasound and CT angiography. RESULTS: From the total 235 patients of this series, one hundred and fifty-three cases met the study inclusion criteria. A total of four thrombotic events appeared, one in the form of deep vein thrombosis and other three in the form of pulmonary thromboembolism. These last patients suffering an embolism died because of it. None of the variables studied had statistical significance for the occurrence of a thrombotic event. All four patients who suffered thrombotic events were receiving anticoagulant drugs, in addition to mechanical compression stockings, because of the presence of risk factors for thrombosis. CONCLUSIONS: By applying the fore mentioned protocol, adequate prevention of thromboembolic events was achieved in this study population of patients undergoing posterior spinal surgery.

[Peripartum cardiomyopathy with biventricular failure plus pulmonary thromboembolism and atrial septal defect]. / Miocardiopatía periparto con fallo biventricular más tromboembolismo pulmonar y comunicación interauricular.

This case report examines peripartum cardiomyopathy (PPCM), a rare variant of heart failure with reduced ejection fraction, which manifests at the end of labor or puerperium. The frequency of this pathology varies globally, and its association with risk factors such as genetic disorders, autoimmune diseases, viral infections, suggests a multifactorial etiology. Diagnostic criteria include: Heart failure secondary to left ventricular systolic dysfunction, manifested in the puerperium or at the end of pregnancy and lack of other identifiable causes of heart failure. The case presents a patient with no significant personal pathological history, who, 17 days post cesarean section developed acute symptoms, including abdominal pain, dry cough and dyspnea. Clinical findings revealed hypoxemia, alterations in blood tests and an echocardiogram that confirmed an atrial septal defect. Multidisciplinary management resulted in successful treatment and the patient was discharged without complications. This case highlights the importance of MCPP, a disease with high maternal mortality. The connection between atrial septal defect and PPCM, as well as the involvement of pulmonary thromboembolism.

Actualización del abordaje de la hipertensión pulmonar tromboembólica crónica / Update in the management of chronic thrombo-embolic pulmonary hypertension

La hipertensión pulmonar tromboembólica crónica (HPTEC) es una forma potencialmente curable de hipertensión pulmonar (HP) que aparece hasta en 3% de los pacientes tras una embolia pulmonar (EP). En estos pacientes, la EP no se resuelve, dando paso a coágulos fibróticos organizados, con el desarrollo de HP precapilar debido a la obstrucción proximal de las arterias pulmonares. También puede desarrollarse una microvasculopatía distal que contribuye al aumento de la resistencia vascular pulmonar (RVP). La ecocardiografía transtorácica (ETT) es la exploración que permite establecer la sospecha de HP. La gammagrafía pulmonar de ventilación-perfusión (V/Q) es la herramienta fundamental en el estudio de los pacientes con sospecha de HPTEC; si es normal, prácticamente la descarta. El cateterismo cardiaco derecho es obligatorio para el diagnóstico. La HPTEC se define como la existencia de síntomas, defectos de perfusión residuales e HP precapilar tras un periodo mínimo de tres meses de anticoagulación. La angiografía pulmonar ayuda a determinar la extensión y la accesibilidad quirúrgica de las lesiones tromboembólicas. Las personas con HPTEC son candidatas a anticoagulación indefinida. La endarterectomía pulmonar es el tratamiento de elección, resultando en una mejoría clínica y hemodinámica significativa. Aproximadamente un 25% de los pacientes presentan HP residual postendarterectomía. La angioplastia pulmonar con balón (APB) es una técnica endovascular dirigida a lesiones más distales, de utilidad para sujetos con HPTEC inoperable o HP persistente/recidivante postendarterectomía. Ambos tipos de pacientes también se pueden beneficiar de tratamiento farmacológico para la HP. Las tres terapias constituyen los pilares de la terapia, que ha evolucionado hacia un enfoque multimodal.(AU)

Chronic thrombo-embolic pulmonary hypertension (CTEPH) is a potentially curable form of pulmonary hypertension (PH) that develops in up to 3% of patients after pulmonary embolism (PE). In these patients, PE does not resolve, leading to organized fibrotic clots, with the development of precapillary PH as a result of the proximal obstruction of the pulmonary arteries. In addition, a distal microvasculopathy may also develop, contributing to the increase of pulmonary vascular resistance. Transthoracic echocardiography is the diagnostic tool that allows to establish the suspicion of PH. Ventilation-perfusion lung scintigraphy is the fundamental tool in the study of patients with suspected CTEPH; if it is normal, virtually rules out the diagnosis. Right heart catheterization is mandatory for the diagnosis of these patients. CTEPH is defined as the existence of symptoms, residual perfusion defects and precapillary PH after a minimum period of three months of anticoagulation. Pulmonary angiography helps determine the extent and surgical accessibility of thromboembolic lesions. CTEPH patients are candidates for long-term anticoagulation. Pulmonary endarterectomy is the treatment of choice, resulting in significant clinical and hemodynamic improvement. About 25% of patients have residual PH post-endarterectomy. Balloon pulmonary angioplasty is an endovascular technique that targets more distal lesions, being potentially useful for patients with inoperable CTEPH or persistent/recurrent PH post-endarterectomy. Both types of patients may also benefit from pharmacological treatment for PH. These three therapies are the cornerstone of CTEPH treatment, which has evolved towards a multimodal approach.(AU)

Underuse of reperfusion therapy with systemic thrombolysis in high-risk acute pulmonary embolism in a Portuguese center.

INTRODUCTION: Reperfusion therapy is generally recommended in acute high-risk pulmonary embolism (HR-PE), but several population-based studies report that it is underused. Data on epidemiology, management and outcomes of HR-PE in Portugal are scarce. OBJECTIVE: To determine the reperfusion rate in HR-PE patients, the reasons for non-reperfusion, and how it influences outcomes. METHODS: In this retrospective cohort study of consecutive HR-PE patients admitted to a thromboembolic disease referral center between 2008 and 2018, independent predictors for non-reperfusion were assessed by multivariate logistic regression. PE-related mortality and long-term MACE (cardiovascular mortality, PE recurrence and chronic thromboembolic disease) were calculated according to the Kaplan-Meier method. Differences stratified by reperfusion were assessed using the log-rank test. RESULTS: Of 1955 acute PE patients, 3.8% presented with hemodynamic instability. The overall reperfusion rate was 50%: 35 patients underwent systemic thrombolysis, one received first-line percutaneous embolectomy and one rescue endovascular treatment. Independent predictors of non-reperfusion were: age, with >75 years representing 12 times the risk of non-treatment (OR 11.9, 95% CI 2.7-52.3, p=0.001); absolute contraindication for thrombolysis (31.1%), with recent major surgery and central nervous system disease as the most common reasons (OR 16.7, 95% CI 3.2-87.0, p<0.001); and being hospitalized (OR 7.7, 95% CI 1.4-42.9, p=0.020). At a mean follow-up of 2.5±3.3 years, the survival rate was 33.8%. Although not reaching statistical significance for hospital mortality, mortality in the reperfusion group was significantly lower at 30 days, 12 months and during follow-up (relative risk reduction of death of 64% at 12 months, p=0.013). Similar results were found for MACE. CONCLUSIONS: In this population, the recommended reperfusion therapy was performed in only 50% of patients, with advanced age and absolute contraindications to fibrinolysis being the main predictors of non-reperfusion. In this study, thrombolysis underuse was associated with a significant increase in short- and long-term mortality and events.

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. / Riesgo de tromboembolismo venoso en la tromboprofilaxis entre aspirina y heparinas de bajo peso molecular tras una artroplastia total de cadera o artroplastia total de rodilla. Revisión sistemática y metaanálisis.

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 analyzed. Mortality, risk of bleeding and surgical wound complications was also analyzed. 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 = .64), DVT (OR = 0.72; 95% CI: 0.43-1.20; P = .21) or PE (OR = 1.13; 95% CI: 0.86-1.49; P = .38) between both groups. No significant differences were found in mortality (P = .30), bleeding (P = .22), or complications in the surgical wound (P = .85) between both groups. These same findings were found in the sub-analysis of only randomized clinical trials (P>.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.

Valoración del tromboembolismo pulmonar relacionado con infección SARS-CoV-2 activa en pacientes embarazadas / Assessment of pulmonary embolism related to active SARS-CoV-2 infection in pregnant women

Objetivo Analizar la muestra de pacientes embarazadas a las que se les realizó una gammagrafía de perfusión pulmonar para descartar la sospecha de tromboembolismo pulmonar (TEP) durante el ingreso en nuestro centro por infección aguda por COVID-19. Material y métodos A todas las pacientes (n=5) se les realizó una gammagrafía SPECT con dosis reducida (111MBq) de 99mTc-macroagregados de albúmina. Las imágenes obtenidas se interpretaron comparando los hallazgos con la imagen radiológica según criterios PISAPED. Resultados De las 5 pacientes, tan solo en una se diagnosticó TEP. En 2 pacientes los hallazgos patológicos de la gammagrafía fueron atribuibles a alteraciones radiológicas por neumonía COVID-19, y otras 2 mostraron una perfusión pulmonar normal. Conclusión Dado lo inespecífico de las manifestaciones clínicas y los valores del dímero D dentro de la COVID-19, así como su similitud con los de TEP, la gammagrafía de perfusión pulmonar, por su alta sensibilidad y menor irradiación que la TC, tiene un papel crucial en el despistaje de TEP en estas pacientes. Los resultados obtenidos son de especial relevancia, a pesar del número limitado de pacientes, dada la ausencia de publicaciones científicas en este grupo de pacientes dentro de la situación excepcional por la pandemia de COVID-19 (AU)

Aim To analyze the sample of pregnant patients who underwent pulmonary perfusion scintigraphy to rule out the pulmonary embolism (PE) suspicion during the acute COVID-19 infection hospitalization period in our hospital. Material and methods SPECT scintigraphy with a reduced dose (111MBq) of 99mTc-macroaggregated albumin was performed in all of the patients (n=5). The obtained images were interpreted by comparing the findings with the radiological images according to the PISAPED criteria. Results Only one of the 5 patients was diagnosed with PE. Two patients obtained pathological findings of the scintigraphy attributable to radiological alterations due to COVID-19 pneumonia, and the other 2 had normal pulmonary perfussion. Conclusion Given the non-specific features of the clinical manifestations and D-dimer values in COVID-19, as well as their similarity to those of PE, the pulmonary perfusion scintigraphy plays a crucial role in the screening of PE in these patients due to its high sensitivity and lower irradiation compared to CT. Despite the limited number of patients, the results obtained have special relevance related to the absence of scientific publications on this group of patients within the context of COVID-19 pandemic exceptional situation (AU)

Treatment of intracardiac thrombi using ultra-slow low-dose thrombolytic therapy: A case report.

A 57-year-old male with previously known severe primary mitral regurgitation was admitted to the intensive care unit (ICU) due to massive venous thromboembolism, associated with right ventricular dysfunction and two large mobile right atrial thrombi. Due to deterioration in his clinical condition despite standard treatment with unfractionated heparin, it was decided to use an ultra-slow low-dose thrombolysis protocol, which consisted of a 24-hour infusion of 24 mg of alteplase at a rate of 1 mg per hour, without initial bolus. The treatment was continued for 48 consecutive hours, with clinical improvement and resolution of the intracardiac thrombi and no complications. One month after ICU admission, successful mitral valve repair surgery was conducted. This case demonstrates that ultra-slow low-dose thrombolysis is a valid bailout treatment option in patients with large intracardiac thrombi refractory to the standard approach.

Anticoagulación en enfermedad renal crónica G4-5 en una red de hospitales de Bogotá

Contexto: la anticoagulación en pacientes con enfermedad renal crónica es un reto terapéutico debido a que la evidencia médica es escasa y los beneficios son discutibles, además, el riesgo de sangrado en estos pacientes es mayor. Objetivo: describir los pacientes con enfermedad renal G4-5 que recibieron terapia anticoagulante oral durante por lo menos tres meses en la Subred Centro Oriente de Bogotá. Metodología: estudio analítico de pacientes con enfermedad renal crónica G4-5 en un hospital de referencia entre enero del 2018 y diciembre del 2021, en el cual se analizaron variables sociodemográficas, clínicas y se realizó una regresión logística sobre los anticoagulantes y la frecuencia de eventos (hemorrágicos o embólicos). Resultados: se evaluó a 75 pacientes con diagnóstico de enfermedad renal crónica G4-5 anticoagulados, donde el anticoagulante más usado fue warfarina (76 %), seguido de apixabán (16 %) y rivaroxabán (8 %). El sangrado mayor se presentó con warfarina (8,47 %), apixabán (10%) y rivaroxabán (16,6 %). No se encontraron diferencias significativas entre el sangrado mayor con warfarina (OR: 2,8; IC 95 %: 0,46-16,9; p = 0,262) y rivaroxabán (OR: 1,86; IC 95 %: 0,18-18,7; p = 0,596), además, el sangrado no mayor y clínicamente relevante fue del 28,9 % con warfarina. Solo se presentó una complicación trombótica en un paciente que recibió rivaroxabán. Conclusiones: en los pacientes con enfermedad renal G4-5 que recibieron warfarina y los anticoagulantes orales directos no se encontraron diferencias significativas en cuanto a la presentación de sangrado mayor y no mayor, clínicamente relevantes.

Background: Anticoagulation in patients with chronic kidney disease is a therapeutic challenge since the medical evidence is scarce and the benefits are debatable since the risk of bleeding in these patients is greater. Purpose: To describe patients with G4-5 kidney disease who received oral anticoagulant therapy for at least 3 months in the central-eastern subnetwork of Bogotá. Methodology: Analytical study of patients with G4-5 chronic kidney disease, in a reference hospital between January 2018 and December 2021, in which sociodemographic and clinical variables were analyzed, and a logistic regression was performed on anticoagulants and the frequency of events (hemorrhagic or embolic). Results: 75 anticoagulated patients diagnosed with G4-5 chronic kidney disease were evaluated. The most commonly used anticoagulant was warfarin (76%), apixaban (16%), and rivaroxaban (8%). Major bleeding occurred with warfarin (8.47%), apixaban (10%), and rivaroxaban (16.6%). There are no significant differences between major bleeding with warfarin (OR: 2.8; 95% CI: 0.46;16.9; p= 0.262), and rivaroxaban (OR: 1.86; 95% CI: 0.18;18.7; p=0.596). Clinically relevant non-major bleeding was 28.9% with warfarin. A thrombotic complication only occurred in one patient who received rivaroxaban. Conclusions: In patients with G4-5 kidney disease who received warfarin and direct oral anticoagulants, no significant differences were found in terms of the presentation of clinically relevant major and non-major bleeding.

Assessment of pulmonary embolism related to active SARS-CoV-2 infection in pregnant women.

AIM: To analyze a sample of pregnant patients who underwent pulmonary perfusion scintigraphy to rule out suspicion of pulmonary embolism (PE) during the acute COVID-19 infection hospitalization period in our hospital. MATERIAL AND METHODS: SPECT scintigraphy with a reduced dose (111MBq) of 99mTc-macroaggregated albumin was performed in all the patients (n=5). The images obtained were interpreted by comparing the findings with the radiological images according to the PISAPED criteria. RESULTS: Only one of the 5 patients was diagnosed with PE. Two patients showed pathological scintigraphy findings attributable to radiological alterations due to COVID-19 pneumonia, and the other two had normal pulmonary perfusion. CONCLUSION: Given the non-specific features of the clinical manifestations and d-dimer values ​​in COVID-19, as well as their similarity to those of PE, pulmonary perfusion scintigraphy plays a crucial role in the screening of PE in these patients due to its high sensitivity and lower irradiation compared to CT. Despite the limited number of patients, the results obtained have special relevance due to the absence of scientific publications in this group of patients within the exceptional context of the COVID-19 pandemic.

Tromboembolismo pulmonar como posible reacción adversa a Quetiapina Reporte de caso / Pulmonary thromboembolism as a possible adverse reaction to Quetiapine Case report

Resumen Algunos estudios sugieren que existe una relación entre el uso de antipsicóticos y el riesgo de tromboembolismo venoso (TEV) y embolia pulmonar (EP). Sin embargo, los resultados siguen sin ser concluyentes. Se trata del caso de un Masculino de 23 años con antecedentes de Esquizofrenia y Depresión tratado quetiapina 800 mg, el cual es encontrado muerto en la cama de un hotel. En la necropsia sin lesiones traumáticas visibles, hallazgos histológicos de tromboembolismo pulmonar masivo con infartos pulmonares secundarios. Laboratorio de Toxicología detectó la presencia de quetiapina, no se detectó alcohol o drogas de abusos. Mediante el Algoritmo De Karch & Lasagna Modificado el tromboembolismo pulmonar fue una reacción adversa con una probabilidad de relación causal posible. Se han informado muchos casos de muerte súbita causada por EP con la exposición a antipsicóticos, pero la relación de su uso y el riesgo de TEV y EP sigue siendo controvertida.

Abstract Some studies suggest a relationship between antipsychotic use and the risk of venous thromboembolism (VTE) and pulmonary embolism (PE). However, the results remain inconclusive. This is the case of a 23-year-old male with a history of schizophrenia and depression treated with quetiapine 800 mg, who was found dead in a hotel bed. At necropsy with no visible traumatic lesions, histological findings of massive pulmonary thromboembolism with secondary pulmonary infarcts. Toxicology laboratory detected the presence of quetiapine, no alcohol or drugs of abuse were detected. Using the Modified Karch & Lasagna Algorithm, pulmonary thromboembolism was an adverse reaction with a probable causal relationship. Many cases of sudden death caused by PE have been reported with exposure to antipsychotics, but the relationship of their use and the risk of VTE and PE remains controversial.

Trombosis venosa profunda masiva en gestante: la importancia de individualizar el plan de acción / Massive deep vein thrombosis in pregnant women: The importance of individualizing the action plan

El tromboembolismo venoso (TEV), incluida la trombosis venosa profunda (TVP) y la embolia pulmonar (TEP) es una afección potencialmente letal y a tener en cuenta en mujeres embarazadas, donde la situación es favorecida por los cambios fisiológicos característicos de la gestación, el parto y el puerperio. El manejo de esta patología en este tipo de pacientes está basado en la anticoagulación, con los beneficios e inconvenientes que ello implica. Presentamos el caso de una mujer embarazada con TVP masiva e intentamos arrojar luz sobre temas como son la vía de parto (vaginal vs. cesárea) o el manejo del tratamiento (heparina de bajo peso molecular [HBPM] vs. heparina no fraccionada [HNF]) de cara a obtener la situación más segura para la paciente.(AU)

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a potentially lethal condition to be taken into account in pregnant women, where the situation is favored by the characteristic physiological changes of the pregnancy, childbirth and the puerperium. The management of this pathology in this type of patient is based on anticoagulation, with the benefits and drawbacks that this implies. We present the case of a pregnant woman with massive DVT and the issues are discussed, such as the method of delivery (vaginal vs. cesarean section) or the management of treatment (LMWH vs. UFH) in order to obtain the safest situation for the patient.(AU)

Incidental pulmonary embolism. Incidence, clinical-radiological features and survival / Tromboembolismo pulmonar incidental. Incidencia, manifestaciones clínico-radiológicas y supervivencia

Objetive: To describe the incidence and features of incidental pulmonary embolism (IPE) and survival of all patients with IPE from January 2012 to December 2014. Rationale: The prevalence of IPE accounts for 1–10% of all pulmonary embolisms (PE). Methods: All radiological reports of computed tomography with intravenous contrast in which the IPE was not suspected were evaluated. The numerical data are expressed by mean and standard deviation (SD); Survival by the Kaplan–Meier analysis and the Log Rank test. Results: We reviewed 7508 reports, detecting 44 patients with IPE (0.6%). Men 64%, age 68 years, pack-year 25, oncological disease 73%, chemotherapy last month before IPE 82%. The predominant histological strain was adenocarcinoma (60%) and epidermoid (20%). The origin of the most common tumor was bronchogenic (27%) and colorectal (14%). The distribution according to the PESI index was mainly I (71%) and II (21%). They received anticoagulation 54%. The location of thrombi was bilateral in 32%. Around 70% were located in main and lobar arteries. Overall survival at one year was more than 70%, being higher in anticoagulated patients (log rank <0.05). Conclusions: The incidence of IPE is low, predominantly in oncological patients. Adenocarcinoma is the predominant strain. Most of them have a low severity index. Survival is higher in anticoagulated patients and higher than in the case of published non-incidental PE.(AU)

Los resultados numéricos fueron expresados mediante media y desviación estándar; Supervivencia por KaplanMeier y test de LogRank. Resultado: Revisamos 7508 informes detectando 44 pacientes con TEPI (0.6%). Hombres 64%, edad 68 años, índice paquetes-año 25, enfermedad oncológica 73%, quimioterapia el mes previo al TEPI 82%. La estirpe histológica predominante fue adenocarcinoma (60%) y epidermoide (20%). El origen del tumor más frecuente fue broncogénico (27%) y colorrectal (14%). La distribución teniendo en cuenta la escala PESI fue predominantemente I (71%) y II (21%). Recibieron anticoagulación el 54%. La localización del trombo fue bilateral en el 32%. En torno al 70% fueron localizados en arterias principales y lobares. La supervivencia global al año fue mayor del 70%, siendo mayor en pacientes anticoagulados (log rank <0.05). Conclusiones: La incidencia de TEPI es baja, predominantemente en pacientes oncológicos. La mayoría presentaron bajo índice de severidad. La supervivencia es mayor en pacientes anticoagulados y mayor que la publicada para embolismos pulmonares no incidentales.(AU)

Utilidad diagnóstica del dímero-D en el tromboembolismo pulmonar de pacientes COVID-19 / DiagnosticutilityofD-dimerin pulmonarythromboembolism in COVID-19 patients

Resumen Introducción: El aumento de la concentración de dímero-D en pacientes COVID-19 se ha asociado a mayor gravedad y peor pronóstico; sin embargo, su rol en predecir el diagnóstico de tromboembolismo pulmonar (TEP), aún es incierto. Objetivo: Evaluar la utilidad del dímero-D plasmático en el diagnóstico de TEP en pacientes con COVID-19. Pacientes y Métodos: Estudio observacional analítico. Se incluyó a pacientes COVID-19 que tenían una angiotomografía computada de tórax (AngioTAC). Se registraron datos clínicos, niveles plasmáticos de dímero-D de ingreso y previo al momento de realizar la AngioTAC. Se identificó la presencia o ausencia de TEP. Resultados: Se incluyeron 163 pacientes; 37(23%) presentaron TEP. Al comparar la serie de pacientes con TEP versus sin TEP, no se encontraron diferencias significativas en características clínicas, ni mortalidad. Hubo diferencias significativas en el nivel plasmático del dímero-D previo a realizar la AngioTAC (3.929 versus 1.912 μg/L; p = 0,005). El área bajo la curva ROC del dímero-D para TEPfue de 0,65. El mejor punto de corte del dímero-D fue de 2.000 μg/L, con una baja sensibilidad y valor predictivo positivo. El valor de corte con el mejor valor predictivo negativo (VPN)fue de 900 μg/L (96%), el cual fue mejor que la estrategia de corte de dímero D ajustado por edad (VPN 90%). Conclusión: La capacidad discriminativa del dímero D para diagnosticar TEP fue baja. En cambio, el dímero D mantiene un alto valor predictivo negativo para descartar TEP, el cual es mayor al valor descrito clásicamente en los pacientes no COVID.

Introduction: Increased D-dimer concentration in COVID-19 patients has been associated with greater severity and worse prognosis; however its role in predicting the diagnosis of pulmonary thromboembolism (PTE), is still uncertain. Objective: To evaluate the usefulness of plasma D-dimer in the diagnosis of PTE in patients with COVID-19. Method: Analytical observational study. COVID-19 patients who had a chest computed tomography angiography (CTA) were included. Clinical data, Ddimer plasma levels on admission and prior to CTA were recorded. The presence or absence of PTE was identified. Results: 163 patients were included, 37 (23%) presented PTE. After comparing the series of patients with PTE versus the series without PTE, no significant differences were found in clinical characteristics or mortality. There were significant differences in the plasma level of D-dimer prior to performing CTA (3,929 μg/L versus. 1,912 μg/L; p = 0.005). The area under the D-dimer ROC curve for PTEprediction was 0.65. The best D-dimer cutoffpoint was 2.000μg/L, with a low sensitivity and positivepredictive value. The cutoff value with the best negativepredictive value (NPV) was 900 μg/L (96%), which was better than the age-adjusted D-dimer cutoff strategy (NPV 90%). Conclusion: The discriminative ability of D-dimer to diagnose PTE was low. In contrast, D-dimer maintains a high negative predictive value to rule out PTE, which is higher than the value classically described in non-COVID patients.

Cardiac complications in a geriatric population hospitalized with COVID-19: The OCTA-COVID cohort.

PURPOSE: The geriatric population is especially vulnerable to coronavirus disease (COVID-19) and its potential complications. We sought to analyze the incidence of cardiological complications in an elderly population hospitalized for COVID-19. METHODS: A prospective observational longitudinal that included patients ≥75 years of age with diagnosis of COVID-19 admitted to the Geriatric Department from March to May 2020. Epidemiological, geriatric, clinical and laboratory test variables were collected. Cardiovascular events, including de novo atrial fibrillation (AF), acute coronary syndrome (ACS), congestive heart failure (CHF), pulmonary embolism and in-hospital death, were documented. A follow-up was carried out at 12 months through a telephone interview as well as using electronic medical records, collecting cardiac events and mortality. RESULTS: 305 patients were included; 190 (62.3%) were female, with median age of 87 years (interquartile range (82-91)). More than half of the patients had a history of cardiac disease, with AF being the most common and affecting 85 (27.9%) patients. During hospitalization, 112 (36.7%) patients died. Eighty-nine (29.2%) patients presented cardiac complications. Acute heart failure was the most prevalent (46; 15.1%), followed by new-onset AF (20; 6.5%), pulmonary embolism (17; 5.6%), and ACS (5; 1.6%). Patients with cardiac complications had a longer hospital stay (p<0.001). During follow-up, 29 (15.1%) died, and 40 (20.8%) patients had a cardiovascular event being CHF the most prevalent complication (16.7%). CONCLUSION: The incidence of cardiovascular complications in geriatric patients is high and is associated with a longer hospital stay. CHF was the most frequent event, followed by AF.

Cardiac complications in a geriatric population hospitalized with COVID-19: The OCTA-COVID cohort / Complicaciones cardiacas en una población geritrica hospitalizada por COVID-19: La cohorte OCTA-COVID

Purpose: The geriatric population is especially vulnerable to coronavirus disease (COVID-19) and its potential complications. We sought to analyze the incidence of cardiological complications in an elderly population hospitalized for COVID-19.Methods: A prospective observational longitudinal that included patients ≥75 years of age with diagnosis of COVID-19 admitted to the Geriatric Department from March to May 2020. Epidemiological, geriatric, clinical and laboratory test variables were collected. Cardiovascular events, including de novo atrial fibrillation (AF), acute coronary syndrome (ACS), congestive heart failure (CHF), pulmonary embolism and in-hospital death, were documented. A follow-up was carried out at 12 months through a telephone interview as well as using electronic medical records, collecting cardiac events and mortality.Results:305 patients were included; 190 (62.3%) were female, with median age of 87 years (interquartile range (82–91)). More than half of the patients had a history of cardiac disease, with AF being the most common and affecting 85 (27.9%) patients. During hospitalization, 112 (36.7%) patients died. Eighty-nine (29.2%) patients presented cardiac complications. Acute heart failure was the most prevalent (46; 15.1%), followed by new-onset AF (20; 6.5%), pulmonary embolism (17; 5.6%), and ACS (5; 1.6%). Patients with cardiac complications had a longer hospital stay (p<0.001). During follow-up, 29 (15.1%) died, and 40 (20.8%) patients had a cardiovascular event being CHF the most prevalent complication (16.7%). (AU)

Introducción: La población geriátrica es especialmente vulnerable a la enfermedad por coronavirus (COVID-19) y sus posibles complicaciones. Nos propusimos analizar la incidencia de complicaciones cardiológicas en una población anciana hospitalizada por COVID-19.Métodos: Estudio longitudinal observacional prospectivo que incluyó a pacientes≥75 años con diagnóstico de COVID-19 ingresados en el Servicio de Geriatría de marzo a mayo de 2020. Se recogieron variables epidemiológicas, geriátricas, clínicas y de laboratorio. Se documentaron eventos cardiovasculares, que incluyen fibrilación auricular (FA) de novo, síndrome coronario agudo, insuficiencia cardíaca congestiva, embolia pulmonar y muerte intrahospitalaria. Se realizó un seguimiento a los 12 meses, mediante entrevista telefónica y accediendo a la historia clínica electrónica, recogiendo eventos cardíacos y mortalidad.Resultados: Se incluyeron 305 pacientes; 190 (62,3%) eran mujeres, con una mediana de edad de 87 años (rango intercuartílico: 82-91). Más de la mitad de los pacientes tenían antecedentes de enfermedad cardíaca, siendo la FA la más frecuente y afectando a 85 (27,9%) pacientes. Durante la hospitalización fallecieron 112 (36,7%) pacientes. Ochenta y nueve (29,2%) pacientes presentaron complicaciones cardíacas. La insuficiencia cardíaca congestiva aguda fue la más prevalente (46; 15,1%), seguida de la FA de nueva aparición (20; 6,5%), la embolia pulmonar (17; 5,6%) y el síndrome coronario agudo (5; 1,6%). Los pacientes con complicaciones cardíacas tuvieron una estancia hospitalaria más prolongada (p<0,001). Durante el seguimiento fallecieron 29 pacientes (15,1%) y 40 (20,8%) presentaron un evento cardiovascular, siendo la insuficiencia cardíaca congestiva la complicación más prevalente (16,7%). (AU)

Doble vena cava inferior y enfermedad tromboembólica / Double inferior vena cava and thromboembolic disease

La doble vena cava inferior (DVCI) es una anomalía congénita poco frecuente, pero con grandes implicaciones clínicas en la planificación quirúrgica y el intraoperatorio de cirugías en las que se aborda el retroperitoneo, así como en la enfermedad tromboembólica.En la siguiente revisión se presenta el caso de una paciente de noventa años con enfermedad tromboembólica y doble vena cava inferior.

Double inferior vena cava (DIVC) is a rare congenital anomaly, but with great clinical implications, both in the surgical and intraoperative planning of surgeries where the retroperitoneum is approached, as well as in thromboembolic disease.In the following report and review, a case of a 90-year-old patient with thromboembolic disease and DIVC is presented.
