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.
The primary objective of this study is to evaluate whether the combination of Pembrolizumab and Axitinib given in the neoadjuvant setting can change the Inferior Vena Cava Tumor Thrombus burden. A decrease in the size of the tumor thrombus can potentially lead to decrease in surgical complications, improve patient related health outcomes, and improve long term outcomes such as progression free survival and overall survival.
The purpose is to conduct a dietary intervention study in which human participants will consume beverages sweetened with erythritol or aspartame, each for 2 weeks, in a randomized crossover design
A functioning dialysis vascular access is critical to the delivery of lifesaving hemodialysis. Arteriovenous graft (AVG) is a surgically created vascular access used for hemodialysis in patients with end-stage renal disease. AVG thrombosis due to underlying flow-limiting stenosis of the graft vein junction and outflow veins is a common complication. Thrombosed AVG can be treated with thrombolysis combined with percutaneous transluminal angioplasty with good immediate success rates. However, the mid-to-long term patency rates following angioplasty have been suboptimal. Sirolimus drug-coated balloon has been shown to be safe and effective in the salvage of thrombosed arteriovenous graft. The investigators hypothesize that sirolimus drug-coated balloon is non-inferior to stent graft in maintaining the patency of thrombosed AVG that is successfully salvaged. This study is conducted to compare the 6-month access circuit primary patency of thrombosed AVG treated with sirolimus drug-coated balloon versus stent graft.
