Filter by:The study is a single center clinical trial to evaluate the efficacy and safety of blood circulation improvement using an investigational medical device, which is a product on the market and it's name is Ceragem Master V6, for the risk group of Deep Vein Thrombosis (DVT) and the ordinary person. The study compares before and after the application by one time application.
Considering observational studies that suggested a relationship between acutely ill medical patients and venous thromboembolism (VTE), interventional studies with anticoagulant medications indicated a marked decline in VTE during and after hospitalization. Despite the therapeutic value of lowering this result, there is a low inclination to utilize anticoagulants in patients hospitalized for acute medical diseases. This observational research aims to assess the appropriateness of venous thromboprophylaxis offered to patients admitted to internal medicine wards.
This study is a prospective, multicenter, real world, observational study intended to understand tmechanical thrombectomy in the treatment of acute deep venous thrombosis of lower extremities, It is estimated that 600 patients with DVT were enrolled in the group at 24 centers nationwide from May 2022 to May2024. we can obtain data on the incidence of sequelae of deep venous thrombosis after PMT, and analyze the factors that may affect the efficacy of PMT.
The ULTREC research project is designed to assess the safety of a negative strategy relying on Colour Doppler Ultrasound (CDUS) for excluding the diagnosis of a new thrombosis. The ULTREC project does not take into account the validity of the CDUS positive criteria used to confirm the diagnosis of Deep Vein Thrombosis (DVT) recurrence. The risk of considering only the negative strategy is to ignore the possibility of having an improvement in sensitivity and negative predictive value at the expense of specificity and positive predictive value and therefore to increase the false positive rate leading to an overdiagnosis of recurrence and an overtreatment, and a potential bleeding risk. In the ULTREC-ANCILLARY study, the research will aim at assessing the validity of baseline CDUS positive criteria for the diagnosis of DVT recurrence. As there is no diagnostic standard to which the results could be compared, it is suggested to validate these criteria based on the evolution of the thrombosis on CDUS performed at D90±5. The hypothesis is that an unchanged appearance under anticoagulation would be in favor of sequelae and will invalidate the initial diagnosis (diagnostic failure)
The study coordinator aims to compare gold standard deep vein thrombosis (DVT) diagnostic performed by a specialist sonographer to a scan by a non-specialist with a newly developed an automated DVT (AutoDVT) detection software device. The title of the project is: Benefit of Machine learning to diagnose Deep Vein thrombosis compared to gold standard Ultrasound. Currently the process from the DVT symptom begin, to diagnosis and then treatment is all but not straightforward. It implements a laborious journey for the patient from their general practitioner (GP) to accident and emergency (A&E), then to a specialist sonographer. However, handheld Ultrasound devices have recently become available and they have been implemented with a machine learning software. The startup company ThinkSono developed a software which is hoped to divide between thrombosis and no thrombosis. In this single-blinded pilot study, patients which present at St Mary's DVT Clinic will be scanned by the specialist and then by a non-specialist with the machine learning supported device. The accuracy and sensitivity of this device will be compared to the gold standard. This would mean that DVT could be diagnosed at point of care by a non-specialist such as a community nurse or nursing home nurse, for example beneficial for multimorbid confused nursing home patients. This technology could reduce A&E crowding and free up specialist sonographer to focus on other clinical tasks. These improvements could significantly reduce the financial burden for the National Health System (NHS). The AutoDVT has a CE (as the logo CЄ, which means that the manufacturer or importer affirms the good's conformity with European health, safety, and environmental protection standards) Certificate under the directive 93/42/ European Economic Community (EEC) for medical devices. It is classified in Class 1 - Active Medical Device - Ultrasound Imaging System Application Software (40873). Furthermore, following standards and technical specifications have been applied: British Standard (BS) European Norm (EN) International Organisation for Standardisation (ISO) 13485:2016, BS EN ISO 14971:2012, Data Coordination Board (DCB)0129:2018, ISO 15233-1:2016.
Ipsilateral popliteal venous the most common access for pharmacomechanical thrombectomy (PMT) in the treatment of acute deep venous thrombosis (DVT), but the result was not satisfactory. The investigators adjust the access to improve the thrombus clearance rate and reduce the incidence of post-thrombotic syndrome (PTS).
The purpose of this study is to evaluate the use of a D-dimer based protocol to screen for thrombotic events in colorectal surgical patients. This study is unique because of the multistage screening process for DVT's using a standardized D-dimer testing methodology and ultrasound that will take place throughout the preoperative, perioperative, and postoperative processes. The data collected from this screening study will help establish the baseline DVT rates in UTMB's colorectal surgical patients before and after surgery. Additionally, the data from this study can help determine if a D-dimer blood test has predictive value in UTMB's colorectal surgical patient population. This study may also provide preliminary evidence for further research regarding the adjustment of D-dimer cutoff values. Specifically for patient subsets such as surgical colorectal patients with a moderate pretest probability and clinical conditions associated with low test specificity
To see whether our increased dosing regimen of unfractionated heparin (UF) and low molecular weight heparin (LMWH) in COVID-19 patients was effective at preventing thrombo-embolic complications. We did regular anti-Xa tests to optimise the dose of our thromboprophylaxis. Furthermore, we want to examine the time it takes to reach adequate anti-Xa levels, to determine additional risk factors and do a subgroup analysis. Lastly, we will study if there are possible complications of our thromboprophylactic therapy.
There is no randomized controlled trial examining surveillance ultrasonography for lower limb DVT in high-risk medical-surgical ICU patients compared to a clinician-directed approach. The DETECT randomized controlled trial addresses the question of whether surveillance ultrasound in critically ill patients by facilitating DVT detection reduces the incidence of PE and lowers all cause 90-day mortality. The primary outcome is 90-day all-cause mortality.
DESTINY D-Dimer is an observational feasibility study, and a collaboration between the University of South Wales and Cwm Taf Morgannwg University Health Board (CTMUHB). The study is based at St. John's Medical Practice in Aberdare, where participant recruitment will take place. Blood D-dimer data will be collected from CTMUHB Pathology Laboratory services, at Prince Charles Hospital. Study blood samples will be obtained by the research student, LAH, under the direction of Dr Owen Thomas at St John's Medical Centre. The participant data will be collected by the research student who will conduct a Wells' Risk Score and perform D-dimer POC tests to generate quantitative data. Data will later be compared by the research student with the diagnoses obtained from Secondary Care at Prince Charles Hospital via analysis of medical records to include a laboratory generated D-Dimer results and additional diagnostics (eg. Doppler). A laboratory based analytical verification of D-dimer POC tests will be undertaken to compare with the current laboratory method. The study will compare the data from the D-dimer POC tests and those gained using laboratory methods at Prince Charles Hospital.
