Active clinical trials for "Thrombosis"

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.

Evaluate the safety and efficacy of the Aventus Thrombectomy System for aspiration thrombectomy in subjects with acute pulmonary embolism.

The CHOICE study suggested that the use of adjunct intra-arterial alteplase after successful endovascular reperfusion in large vessel occlusion acute ischemic strokes may result in a greater likelihood of excellent neurological outcome at 90 days. However, CHOICE was a phase-2 trial and almost exclusively enrolled anterior circulation occlusions. Therefore, data on the safety and efficacy of post-endovascular reperfusion IAT in posterior circulation stroke is lacking. In general, anterior circulation strokes are associated with a higher risk of ICH than posterior circulation strokes. Therefore, we believe it might be safer to perform post-endovascular reperfusion IAT posterior circulation stroke. Also, there are more perforator artery in the posterior circulation, IAT would be more likely to show its benefit. Therefore, we would like to explore IA rt-PA for posterior circulation stroke after successful MT in our RCT.

This study is a multi-center, randomized, open-label, double-blind, positive-controlled phase II clinical study evaluating the efficacy and safety of different doses of SHR2285 tablets vs. enoxaparin for the prevention of postoperative venous thromboembolism in patients undergoing elective unilateral total knee arthroplasty.

The purpose of this study is to evaluate the safety and efficacy of hepatic arterial infusion chemotherapy combined with Lenvatinib and PD-1 inhibitors compared to Lenvatinib plus PD-1 inhibitors for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT).

The objective of the study is to conduct a Bayesian randomized trial comparing non-elastic compression garments applied with high pressure (Circaid group) with no compression (control group) in reducing signs and symptoms in the acute stage of DVT and subsequent postthrombotic syndrome. With a hypothesis that the Circaid group will present a quicker and more marked reduction of pain and leg swelling in the acute stage of DVT, as well as a 20% decrease in the frequency of postthrombotic syndrome within six months from the time of diagnosis of the acute deep vein thrombosis episode.

To compare the impact on survival of neo-adjuvant TAI for patients with HCC and PVTT who underwent hepatectomy.

Non-valvular (NV) atrial fibrillation (AF) increases the risk of stroke by approximately fivefold. The atrial thrombi associated with AF are seen within the left atrial appendage (LAA) in most cases (> 90%). Anticoagulation with a vitamin-K antagonist (VKA) is recommended to prevent thromboembolic complications and to resolve thrombi. Non-VKA oral anticoagulants (NOACs) have replaced the VKA for the thromboprophylaxis in patients with NVAF since 2010. Therefore, NOAC can be the excellent alternative to VKA concerning resolving preexisting LAA thrombi because of its rapid onset of action and no need of bridging with heparin. However, there is still lack of data regarding the optimal treatment for patients with AF and thrombi in LAA with NOAC. There are only several case reports of the efficacy of NOACs in resolving LAA thrombi available. Edoxaban, which has data showing efficacy and safety in thromboprophylaxis, can be the new option for treatment of patients with AF and LAA thrombi. The purpose of this study is to evaluate the efficacy of Edoxaban in resolving the LAA thrombi, which is related with nonvalvular AF.

To evaluate the efficacy and safety of combination of anticoagulant and antiplatelet therapy on the patency of iliac vein at 12-month post stenting in patients with acute proximal DVT and ipsilateral iliac vein stenosis who received percutaneous mechanic thrombectomy and iliac vein stenting.

To study the effect of rivaroxaban anticoagulant therapy for 12 weeks in patients with left ventricular mural thrombus by contrast echocardiography before and after treatment, so as to provide basis and foundation for further study and treatment selection in the future; To provide further relevant data for the treatment outcome, treatment duration and influencing factors of left ventricular mural thrombosis; It is of great sociological and health economic significance to find more effective and safe anticoagulant treatment strategies for patients with left ventricular mural thrombosis, which will reduce the incidence of embolism and bleeding.
