Filter by:Migration of a thrombus in the pulmonary circulation is the leading cause of pulmonary embolism (PE). It can be prevented mechanically by implanting a vena cava filter (VCF) in the inferior vena cava. The implation of a VCF is indicated for patients with acute PE and a contraindication to anticoagulation, with an acute deep vein thrombosis (DVT) without PE and a contraindication to anticoagulation or with acute venous thromboembolism (less than 3 months) in whom an interventional gesture at hemorrhagic and thromboembolic risk contraindicates anticoagulation. The purpose of this study is to describe the rates of implantation, removal and complications associated with the use of the optional ALN OATF VCF in current practice.
Identify risk factors for developing chronic thromboembolic pulmonary hypertension after acute pulmonary embolism. Determine echocardiographic predictors of chronic thromboembolic pulmonary hypertension. Determine the radiological predictors of chronic thromboembolic pulmonary hypertension in CT pulmonary angiography.
Retrospectively analyze the risk factors of VTE in 5774 patients with thoracic trauma from 33 hospitals in China, and established a risk prediction model
The purpose of this study is to prospectively validate the first PUMCH model for acute PE severity and prognosis prediction based on multi-center data constructed in the pre-project period based on national population data, and to optimize the PUMCH model based on artificial intelligence clustering algorithm.
Chronic thromboembolic pulmonary hypertension [CTEPH] is caused by pulmonary emboli that have enlarged in pulmonary arteries and have become organized into the vessel wall. Many patients with CTEPH are treated with balloon pulmonary angioplasty [BPA] which mechanically opens the narrow pulmonary arteries. It is unclear how much downstream functional pulmonary capillary surface area [FCSA] is recovered during BPA. We plan to measure FCSAIn CTEPH patients, before and after a session of BPA.
The aim of this pilot study is to assess the feasibility of a larger study to determine the Adjust-Unlikely algorithm safety and efficiency for diagnosing PE. The pilot study objectives are to: 1. Determine study recruitment rate, per site, per month 2. Determine study 90-day loss to follow up rate 3. Estimate of the proportion of enrolled patients who test negative for PE at initial assessment using the Adjust-Unlikely rule 4. Estimate of the Adjust-Unlikely algorithm efficiency 5. Compare excluded and missed-eligible patients to study participants: age, sex and prevalence of PE diagnoses at initial testing. The pilot study hypothesis is that the investigators can recruit at least 20 patients per month and successfully follow at least 90% of patients for 90 days.
The primary objective of this trial is to evaluate the safety and efficacy of treatment with anticoagulation alone versus anticoagulation and mechanical aspiration thrombectomy with the Indigo Aspiration System for the treatment of intermediate-high risk acute pulmonary embolism (PE).
1. Assess performance of PERFORM score in predicting outcome in CTPA confirmed patients. 2. Compare PERFORM score with the currently validated PESI in risk stratification of patients
Aim of the work: 1. To compare conventional medical therapy versus catheter-directed therapy in intermediate high risk acute pulmonary embolism. 2. To define predictors of progression from intermediate to high-risk in medically-treated patients for ideal timing for intervention.
Evaluation of initial safety and clinical feasibility of the Viper Catheter System for thrombectomy in acute submassive pulmonary embolism (PE).
