Filter by:The goal of this clinical trial is to evaluate tailored duration of long-term anticoagulant treatment after a first venous thromboembolism based on individualized risk assessments of recurrent VTE and major bleeding risks. Participants will be asked to fill in a questionnaire and take a buccal swab, which are used for an individual estimation of the risks of recurrent VTE and bleeding. Based on these risks a treatment advise will be made, or randomised in a subgroup of patients.
This study will conduct a prospective single blind controlled study on the clinical efficacy and safety indicators of 50 cancer patients with acute lower limb deep vein thrombosis (DVT). The patients were randomly divided into an experimental group (improved mechanical thrombectomy (PMT) group) and a control group (traditional simple anticoagulation group) using the "envelope method", with 25 cases each. After the end of treatment, clinical prognosis evaluations were conducted on the patient's vital signs, symptoms and signs, lower limb Doppler ultrasound examination, patient PTS score (Villalta score), quality of life score (QOL), etc. at 3, 6, and 12 months. Adverse events, the presence or absence of thrombus recurrence, and re surgical intervention were recorded. This study is expected to propose a new strategy for the treatment of acute DVT in cancer patients, thereby improving the overall level of VTE prevention and treatment.
The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
Evaluation of the Safety and Efficacy of the Symphony Thrombectomy System in the Treatment of Pulmonary Embolism
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.
The goal of this multicentric clinical trial is to compare the incidence of pulmonary thromboembolism (PTE), assessed through AngioCT, in the endovascular treatment of acute thrombosis in native and prosthetic arteriovenous fistulas (AVF). The main questions it aims to answer are: - What is the difference in the incidence of pulmonary thromboembolism (PTE) assessed by AngioCT in endovascular treatment of acute thrombosis of native and prosthetic arteriovenous fistulas using balloon thrombectomy versus thromboaspiration systems? - What is the primary patency rate of arteriovenous fistulas treated with balloon thrombectomy versus thromboaspiration systems? - What is the clinical success rate in the treatment of arteriovenous fistulas using balloon thrombectomy compared to thromboaspiration systems? - What are the costs associated with the different thrombectomy techniques in the treatment of arteriovenous fistulas? Participants will be underwent to balloon thrombectomy versus thromboaspiration systems. Researchers will compare the patients treated with balloon thrombectomy and thromboaspiration systems to see if the incidence of PE is comparable and to evaluate the primary and secondary patency rates of both thrombectomy techniques, the clinical technical success rate, and the costs associated with each technique.
This study is a single-arm, multicenter clinical study to evaluate the efficacy and safety of SBRT combined with cardonilizumab and lenvastinib in the treatment of unresectable hepatocellular carcinoma with portal vein tumor thrombus
This study is to look at the success of Intracardiac Echocardiography (ICE) in the Watchman procedure. Currently the process is to use a Transesophageal Echocardiography (TEE) to place the Watchman in patients. This study is aiming to show how the ICE is just as effective in placing the device correctly and effectively.
Recombinant staphylokinase (r-SAK) is a third-generation thrombolytic agent produced by genetic engineering technology in 1985, which has better thrombolytic effect than streptokinase (SK) and urokinase (UK). It has similar biological properties to natural SAK, is highly selective to fibrin, does not activate systemic fibrinolysis, and can dissolve clots in a short period of time without significantly increasing the risk of bleeding, especially for platelet-rich arterial clots. Previous studies have shown that the thrombolytic revascularization rate of r-SAK is significantly better than that of r-SK and UK at the same dose in the rabbit model of acute femoral artery occlusive thrombosis. The revascularization rate of coronary artery at 90 minutes after thrombolysis was significantly higher with r-SAK than r-tPA. The combination of thrombolytic drugs and nanocarriers may provide a new solution for the existing thrombolytic therapy. Inspired by the natural affinity of platelets (PLT) in hemostasis and pathological thrombosis, we have developed a thrombus targeting nanocarrier, which is a platelet membrane cloaked r-SAK（PLT-SAK）and compare the thrombolytic effect of PLT-SAK with different doses of free r-SAK on human arterial thrombus, aiming to further improve the thrombolytic effectiveness of r-SAK.
The investigators aimed to design this randomized control trial to compare rivaroxaban and apixaban with warfarin in Left ventricular thrombus resolution by - Success rate of left ventricular thrombus resolution on follow up echocardiograms to be done at 1st, 3rd and 6th months after starting on these drugs. - Compare the adverse events of each drug in terms of major bleeding and stroke on follow up. Left ventricular thrombus (LVT) leads to thromboembolism in about 10-15% cases. Currently, guidelines recommended therapy for LVT is warfarin but treating LVT with warfarin is challenging due to - Its narrow therapeutic window. - Drug-drug and drug-food interaction. - Frequently tested International normalization ratio (INR) and cost effectiveness especially in low to middle income countries. In contrast Rivaroxaban and Apixaban has no drug-food or major drug-drug interaction and moreover it doesn't require frequent checks on INR and that's the reason Rivaroxaban and apixaban use in LVT is gaining traction over time but there is paucity of data both nationally and internationally. So further studies are required to evaluate the efficacy and safety of rivaroxaban and apixaban in comparison to warfarin in LVT, especially in low to middle income countries.
