tromboembolismo pulmonar

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...

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...

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. MATERIAL AND METHODS: 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...

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...

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...

BACKGROUND: Pulmonary embolism (PE) is a complication reported in the adult population with coronavirus disease 2019 (COVID-19); however, its documentation in the pediatric population is limiteda. CASE REPORT: We report the case of a 15-year-old male with obesity and Down syndrome who was admitted for severe COVID-19 pneumonia. On day 7 of admission, he presented with chest pain, hemoptysis, respiratory distress, and marked elevation of D-dimer. Pulmonary CT angiography found an extensive thrombus in the right lower lobar artery...

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...

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...

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 (111 MBq) 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...

A 53-year-old male patient with history of repaired hernia, who is admitted for 5 days of progressive dyspnea with diagnosis of abdominal sepsis, a computed tomography angiography was made, revealing pulmonary embolism in bilateral main pulmonary artery, and cardiac thrombectomy was performed.

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...

The International Consensus on Venous Thromboembolism (ICM-VTE), will change our current practice as most recent evidence is included. This fact is not usual in most clinical practice guidelines to date. Many orthopedic and trauma procedures do not require thromboembolic prophylaxis, but it should be considered depending on individual risk factors or major surgeries (total hip or knee arthroplasty, spine surgery or fractures that require immobilization and weight bearing restriction). Within the prophylaxis options, we must notice the strength of the drug preventing venous thromboembolism, but also the effect of hemorrhage and bleeding that it may produce...

Recently, it has been suggested that tranexamic acid should be administered only in those patients with hyperfibrinolysis determined using viscoelastic assays, as severely injured patients may present with fibrinolytic shutdown. However the last European guidelines on management of major bleeding and coagulopathy following trauma endorse the use of tranexamic acid to the trauma patient who is bleeding or at risk of significant hemorrhage as soon as possible without waiting for viscoelastic results. We present a severely blunt trauma patient treated with on-scene administration of tranexamic acid that developed immediate pulmonary embolism...

We performed a single center retrospective study in patients wi th pulmonary embolism (PE) undergoing catheter directed thrombolysis (CDT) from 2014 to 2020. Efficacy was defined by mean pulmonary pressure drop, and safety was assessed by intracranial and severe bleeding (defined by GUSTO). Forty-three patients were included, aged 64 (56-79) years old, 5 (12%) with shock, most with right ventricle dilation (95%) and bilateral PE (95%) or unilateral (5%) in patients with only one functional lung. CDT was used as first treatment (53%), upscale after anticoagulation alone (42%), or after failed systemic thrombolytics (5%)...
