Active clinical trials for "Thrombosis"

To show if a combination therapy of rivaroxaban plus Aspirin® is more efficient (superiority testing) as rivaroxaban alone in the prevention of early venous stent thrombosis in patients suffering from post-thrombotic syndrome in the first 6 months following endovascular therapy To demonstrate tolerability of combination therapy of Aspirin® plus rivaroxaban in long-term treatment.

The purpose of this study is to assess the safety and efficacy of the OsciPulse System in reducing serum d-dimer levels in hospitalized ischemic stroke patients.

Recent guidelines for the management of ST-elevation myocardial infarction (STEMI) recommend against the routine use of thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) (Class III indication). Yet, so far, there is limited data regarding its role STEMI patients with heavy thrombus burden (TB). The aim of this trial is to evaluate the effects of manual TA and PCI in comparison to conventional PCI alone in a real-life clinical trial among heavy TB STEMI patients undergoing PPCI.

The chemoprophylaxis of deep vein thrombosis (DVT) with subcutaneous low-molecular-weight heparin (enoxaparin) in the postoperative period of elective surgeries is already well established in the literature and in clinical practice. However, the use of this medication can have a financial impact on the patient and the parenteral presentation itself is associated with pain at the application site, which can make it difficult for patients to adhere.

The objective of the MEDIS study is to determine if subjects experiencing an Acute Ischaemic Stroke due to large vessel occlusion, treated with IV tPA combined with the MED procedure have a greater likelihood of recanalisation 30-90 minutes after the completion of tPA infusion than subjects treated with IV tPA (plus sham device). Safety of the MED System Procedure will be evaluated by the incidence of symptomatic PH-2 haemorrhagic transformation within 24 hours following the procedure. Lastly, a health economics study will be conducted to estimate health care costs for each treatment.

Direct Oral Anticoagulants INTRODUCTION: DOAC's looks like an attractive alternative to VKA because they offer important advantages beyond their easiness of administration, like less interactions and no need of laboratory monitoring. 1 All oral anticoagulant regimens but not aspirin were associated with a lower risk of recurrent VTE, while only VKAs were associated with a higher risk of major bleeding. 2 There have been significant differences between VKAs and DOACs in the risk of major bleeding by the current study size. Even though the risk of major bleeding with VKAs may be lower in patients already challenged to anticoagulation treatment. 3 Furthermore, when deciding on longer term secondary prevention of VTE, DOACs appeared safer than standard-intensity VKAs, taking clinically relevant bleeding or any bleeding into consideration.4-5 Until now there is no randomized controlled trial assessing the role of oral direct anticoagulant as a prophylaxis for catheter associated venous thromboembolism. Aim of the work: To evaluate the efficacy of direct oral anticoagulants as a prophylactic anticoagulation in thromboprophylaxis of catheter induced thrombosis. Patients and methods Study location: The study will be conducted at the department of vascular surgery in Mansoura University, Faculty of Medicine, Mansoura, Egypt . Type of study: Randomized Controlled Prospective study Study duration: 2 years: 2022-2024 Sample size: It will include all patients presented to our department fulfilling the inclusion criteria. Study population: The study will be conducted in patients with any permanent catheter inserted intravenous either femoral or jugular either for hemodialysis or replacement therapy . Inclusion criteria: Any permanent catheter inserted intravenous either femoral or jugular either for hemodialysis, replacement or chemotherapy. Exclusion criteria: History of central venous occlusion, contraindication of direct oral anticoagulants. Consent: Patients must sign informed consent about possible complications from the therapy. Data collection: The demographics, symptoms, and preoperative clinical data will be collected. History Data: including underlying medical conditions, any previous associated morbidity. Examination: Venous examinations. Laboratory: Blood picture, Blood sugar level, Kidney functions, Liver functions and Coagulation profile. Imaging: Duplex US Method of Randomization: Computer-based Therapies group A : Apixaban 2.5 mg twice group B : Rivaroxaban 10 mg plus placebo group C : Placebo without anticoagulation Follow up All patients are followed by duplex ultrasonography to assess the thrombosis at the tip of catheter or around the catheter 10 days postoperative and 1, 3, 6, months then after one year, venography is indicated if the clinical evaluation not matched with sonographic results.

Point-of-care ultrasound (PoCUS) is a rapidly evolving method of clinical assessment within the intensive care unit (ICU) with training predominantly aimed at physicians. Routine whole-body PoCUS (lungs, heart, abdomen and blood vessels) when conducted by physicians benefits patient care and outcomes including reducing the risk of prolonged ICU stay (>7 days) and mechanical ventilation as well as reducing utilisation of other diagnostic tests. However, physician-only use of PoCUS does not allow for use as a routine assessment method in the ICU due to the low physician to patient ratio and poor ultrasound accreditation rate. Providing other healthcare professionals such as Advanced Critical Care Practitioners (ACCPs), ICU nurses and physiotherapists with PoCUS skills increases the proportion of trained staff to perform routine PoCUS in the ICU. This could aid earlier identification of abnormal pathology, earlier treatment, and prevent patient deterioration. The advancement of handheld PoCUS technology is making ultrasound more portable, cheaper and easier to use. The increased accessibility of PoCUS combined with growing evidence of its diagnostic accuracy compared to other modes of imaging means PoCUS use is gaining traction globally. However, little to no research exists investigating the feasibility of implementing scheduled interprofessional PoCUS in the ICU and its impact on patient outcomes. This study aims to evaluate the acceptability and feasibility of a quick and simple whole body ultrasound scan performed by trained ACCPs, ICU nurses, physiotherapists, and doctors at set time points throughout the patients ICU stay. The investigators want to find out the most common barriers and facilitators to intervention implementation and to explore the key clinical outcomes for use in a future definitive RCT.

The goal of this observational study is to investigate the incidence, current management practices, and outcomes in pediatric patients with HAC after liver transplantation. Research question: What are the overall incidence of HAC and the effectiveness of all treatment strategies for HAC after pediatric LT? What are the current management practices in the experience of centers, anticoagulant therapy, screening protocol, and assessment criteria for HAC after pediatric LT? The burden of participation is considered to be minimal, and limited to the questionnaires.

We aim to assess the the efficiency and safety of N-acetylcysteine for prevention of thrombotic events after allogenic hematopoietic stem cell transplantation.

Critically ill patients require antithrombotic prophylaxis. At the same time, majority of them is receiving various vasopressors. The aim of the study is to determine whether there is a difference in anti-Xa activity, which is a marker of anti thrombotic activity of low molecular weight heparins, between the patients receiving norepinephrine with argipressin, compared to those receiving norepinephrine alone.
