Filter by:This prospective cohort study will provide information about: Characteristics of Rivaroxaban use in patients who are prescribed Rivaroxaban for the first time compared to patients who are prescribed standard of care for the first time. The occurrence of intracranial haemorrhage, gastrointestinal and urogenital bleeding, and the occurrence of non-infective liver disease.
The Crux Vena Cava Filter (VCF) Registry is a clinical study, sponsored by Volcano Corporation, to evaluate the short and long term performance and clinical outcomes of the Crux Vena Cava Filter System.
The purpose of this study is to determine whether the novel aspiration thrombectomy device combined with catheter-directed thrombolysis is effective in the treatment of acute iliofemoral deep venous thrombosis (IF-DVT).
Venous thromboembolism (VTE) is a leading cause of death among hospitalized patients, and is an important patient safety issue in plastic surgery. Previous work has shown that enoxaparin prophylaxis can prevent many post-operative VTE events, and current American Society of Plastic Surgeons guidelines support enoxaparin prophylaxis for high-risk patients. Highest risk patients often have cancer or trauma reconstruction. Primary outcomes include 1) peak and trough steady-state aFXa levels in response to standard and escalated doses of enoxaparin and 2) the proportion of patients with appropriate aFXa levels pre and post initiation of a clinical protocol for enoxaparin dose adjustment. The investigators expect that standard dosing will result in inadequate aFXa peak and trough levels, and that the clinical dose adjustment protocol will significantly improve the proportion of in-range aFXa levels. The investigators will also develop a linear regression-based equation to calculate, based on patient-level factors, the required dose of enoxaparin to generate in-range aFXa levels. This research may show that the current "one size fits all" approach to enoxaparin prophylaxis is insufficient. In the trauma and orthopaedic populations, patients with low initial aFXa levels are significantly more likely to develop deep venous thrombosis. Thus, this study has important implications for appropriate enoxaparin dose magnitude and frequency, and may ultimately help to decrease the substantial morbidity and mortality associated with post-operative VTE.
Patients with cancer hospitalized for an acute medical illness have an increased risk of venous thromboembolic events. Although international guidelines suggest the use of thromboprophylaxis in these patients, the recommendations are based on studies which included a percentage of patients with cancer without primarily focusing on this high risk group. Since patients with cancer present an increased risk of bleeding complications it is critical to evaluate the safety of thromboprophylaxis in the cancer group. Recent studies suggest a limited use of thromboprophylaxis in these patients. The aim of this study is to evaluate the use, efficacy and safety of thromboprophylaxis in medical cancer patients hospitalized for an acute medical disease. Design: observational, prospective study Primary end-point: incidence of major and clinically relevant non major bleeding during hospitalization Secondary endpoints: frequency of use, doses and contraindications for pharmacological thromboprophylaxis; venous thromboembolic events up to three months after discharge
The investigators have recently developed a registry of missed doses of VTE prophylaxis that includes retrospective data on missed doses of VTE prophylaxis. To decrease rates of VTE prophylaxis refusal, the group has developed a patient-centered education bundle that will be delivered as an in-person, 1-on-1 discussion session with a nurse educator. Supporting education materials include a 2-page education sheet and an educational video. The investigators hypothesize that patient refusal of VTE prophylaxis is associated with significant knowledge gaps among patients regarding patients' risk of developing VTE and the benefits of VTE prophylaxis and that delivering an education bundle to patients that refuse VTE prophylaxis will improve compliance with VTE prophylaxis and decrease rates of VTE.
To determine the effect and safety of anticoagulation after endoscopic therapy in cirrhotic patients with portal vein thrombosis and to explore whether it can decrease the short-term rebleeding rate.
The purpose of this study is to evaluate the safety and effectiveness of the LUMIFI with Crux VCF System for deployment of the Crux VCF. The study will compare the method of Crux VCF deployment using the LUMIFI with Crux VCF System (IVUS guidance) with the historical results of the Crux VCF System (fluoroscopic guidance). The study will include enrollment into a roll in phase consisting of 2 study subjects per site prior to enrollment into the primary treatment phase for primary analyses. The purpose of the roll in phase is to assure compliance with site training on the use of the investigational device and protocol workflow.
Prospective validation of an age-adjusted D-dimer cut-off to rule out deep vein thrombosis (DVT)
PRESERVE is a multi-center, prospective, open-label, non-randomized investigation of commercially available IVC filters from 6 manufacturers placed in subjects for the prevention of pulmonary embolism (PE). This study will enroll up to 1,800 IVC filter subjects (with a maximum of 300 subjects per IVC filter brand) at up to 60 sites in the US. The primary objective of this investigational device exemption (IDE) clinical investigation is to evaluate the safety and effectiveness of the commercially available IVC filters (retrievable and permanent) in subjects with clinical need for mechanical prophylaxis of PE with an IVC filter.
