Filter by:Cancer patients with Central Venous Catheter (CVC) Associated Deep Vein Thrombosis (DVT) will be treated with Low Molecular Weight Heparin (LMWH) and apixaban. Study duration is 12 weeks.
To clarify the effectiveness and safety of the direct factor Xa inhibitor rivaroxaban in domestic clinical use for patients with deep vein thrombosis and pulmonary embolism
The patients admitted in hospital who had midline catheter inserted in upper limb are followed-up for the presence of complications related to catheter introductions. The symptoms and signs of upper limb thrombosis are recorded. The diagnosis is confirmed by sonography examination. In the selected group of asymptomatic patients sonography examination is done 8 to 10 days after cathether insertion in order to detect the incidence of the asymptomatic thrombosis
Portal vein thrombosis (PVT) is defined as an obstruction of the portal vein. The prevalence of PVT is 10-25% and incidence is about 16% in cirrhotic patients. PVT leads to increased intrahepatic resistance, decreased portal velocities, splanchnic vasodilatation, and stagnant flow. Portal vein recanalization (PVR) with transjugular intrahepatic portosystemic shunt (TIPS) is aimed at restoring main portal vein (PV) flow in chronic PVT. In this study, we will review the safety and outcomes of this approach.
In neurosurgical patients, the risk for venous thromboembolic events (VTE) is high due to the relatively long duration of surgery, the high occurrence of prolonged immobilization of patients due to paresis of the legs or intracranial pathology causing inability to mobilise2. Moreover, intracranial and intraspinal tumours and subarachnoid haemorrhage cause hypercoagulability, which increases the risk on VTE. There is a high degree of diversity in attributed risk on thrombosis in the neurosurgical patient cohort. Due to this diversity, insufficient power of performed studies and lack of careful phenotyping and description of risk factors in previous studies on deep venous thrombosis (DVT) prophylaxis, as yet the optimal DVT prophylaxis in neurosurgery remains unclear. A prospective randomized study with adequate power and detailed information on patient related factors (malignancy, subarachnoid haemorrhage, prevailing coagulopathies), type of surgery, duration of surgery, and postoperative immobilisation will allow us to identify the optimal treatment strategy for high risk neurosurgical patients. In the current study all patients that fulfil the inclusion criteria will be subjected to post-operative systematic evaluation of VTE by echo-duplex investigation.
This is a prospective, randomized vanguard trial of trauma patients admitted to the trauma surgery service at Intermountain Medical Center who are deemed to be at high risk for venous thromboembolism. Once identified and enrolled, subjects will be randomized to receive bilateral lower extremity duplex ultrasound surveillance versus no surveillance. The study will compare the two groups with regard to deep vein thrombosis, pulmonary embolism, and major and clinically relevant bleeding episode rates, both during the index hospitalization and at 90 days post-discharge.
Aortic valve replacement with a biological prosthesis is the most common valve surgery performed with about 1000 operations performed in Denmark each year. Further, the introduction of percutaneous stent valves will increase these types of replacements in the years to come. A biological valve is a foreign body prone to cause thrombus formation at least until the valve is covered with recipient endothelium. There are no conclusive studies of anticoagulation and the investigators have shown stroke to be a common complication. Guidelines have variably recommended aspirin or rivaroxaban for anticoagulation, and currently aspirin is the most common recommendation. In a register study, the investigators have shown that proper anticoagulation with warfarin is likely to be superior. There is a clear need for a large randomised study of aspirin versus anticoagulation for biological aortic valve replacement. This protocol describes a randomised study where 1000 patients will be randomised to receive either rivaroxaban or aspirin for 6 months following aortic valve replacement with a biological prosthesis. The primary efficacy endpoint is a combined event of all-cause mortality and hospitalisation for either acute myocardial infarction or stroke. This study has the power to settle a discussion of appropriate anticoagulation for this operation
Warfarin is a commonly used blood thinner to treat and prevent blood clots. It is important to take the right dose of warfarin because too much can increase the risk of bleeding and too little can increase the risk of blood clots. This is why patients are closely monitored especially when they begin warfarin therapy. When clinicians prescribe warfarin, they have to consider different factors such as patient's age, body size, diet, and other medications that can interact with warfarin. Certain genes have also been found to affect warfarin dose. Individuals have variations in these genes, which can help explain why some patients need higher dose and others require less. These factors have been used to better predict a patient's warfarin dose requirement. However, these predictions were created based on Caucasian populations and they may not be accurate in predicting a safe warfarin dose if a patient is not Caucasian. This study aims to identify new genetic variation that affects warfarin dosing in Hispanic and Latino populations and try to better predict a Hispanic or Latino patient's warfarin dose requirement.
It is a prospective and multi-center clinical research in China to compare the efficacy, safety and related impact factors between TACE alone and endovascular brachytherapy combined with stent placement and TACE for HCC with main portal vein tumor thrombus.
The purpose of this study was to compare the efficacy of Percutaneous mechanical thrombectomy (PMT) followed by standard anticoagulant therapy, with anticoagulation therapy alone, for the treatment of acute proximal lower extremity deep vein thrombosis.
