Filter by:Individuals with Chronic Venous Insufficiency (CVI) face a number of complications, such as, muscular dysfunction, limited ankle range of motion(ROM) and diminished calf muscle pump function. Exercise therapy has been shown to improve calf muscle pump function and symptoms and may provide additional therapeutic benefits. It has been reported that structured exercise has the ability to improve ankle joint range of motion, calf muscle strength and calf muscle pump function. Participants will receive the 12-week structured resistance exercise programme, 'Strength from Within', a warm up and cool down, walking programme and range of motion exercises. Participants will complete the Short Form quality of life (SF-36) Health Survey and the venous clinical severity score questionnaire. Baseline testing will be conducted. The following measures will be employed in the study through a baseline testing and repeated at the end of the study period (week 12): Functional ambulatory measurements, physical activity measurements (muscle endurance), isokinetic testing (strength), duplex ultrasound scanning. A combination of upper and lower body structured exercise as well as, ankle join range of motion and a walking regimen has the potential to have a significant impact on an individual's calf muscle pump function and avoid these potentially harmful side effects of lower body exercise programmes
The purpose of this study is to determine if the use of image-guided, endovascular therapy (EVT) is an effective strategy with which to reduce Post Thrombotic Syndrome (PTS) disease severity and improve quality of life in patients with established disabling iliac-obstructive post thrombotic syndrome (DIO-PTS).
To evaluate the safety and effectiveness of the BlueLeaf System for the restoration of venous competence for the treatment of symptomatic chronic venous insufficiency (CVI).
Venous disease effects 25% of the population and most healthy people experience venous symptoms after standing for too long. The prime function of leg veins is drainage. Failure leads to a condition called chronic venous insufficiency (CVI) with leg pain, heaviness, swelling, varicose veins, ankle skin changes, eczema and occasionally venous ulcers. The aim of the study is to identify blood components (biomarkers) that occur during the damaging phase of standing versus the healing phases of lying recovery and with medical compression stockings. This will be achieved by taking a blood sample from the ankle region at 3 separate visits (days) to the vascular laboratory at Ealing Hospital. The first visit will be after supervised standing for 1 hour. The second after supervised lying and the third standing whilst wearing a medical compression stocking. Healthy volunteers will be compared to patients with advanced CVI. The potential importance to patients and the public is threefold. Firstly, biomarker profiles will be obtained in each of the 3 states to increase understanding in the cellular mechanisms of damage and recovery. In this way "bad" and "good" biomarkers can be identified. Secondly, drug treatments may develop from this research to adjust biomarkers towards a favourable profile. Thirdly, the success of treating CVI with surgery, venous intervention or compression can be monitored. Whilst it is known that relief of gravitational stress is the treatment for all forms of CVI, the mechanisms of repair and its discrimination from damage have yet to be identified.
More than 100 hospital based outpatient wound centers in the USA and Puerto Rico agree to transmit structured data on all patients followed with chronic wounds and ulcers (e.g. diabetic foot ulcers, venous ulcers, pressure ulcers, arterial ulcers, surgical wounds, and traumatic wounds). Data are collected at point of care including adherence to wound care quality measures developed by the USWR as a Qualified Clinical Data Registry (QCDR).
There is a difference concerning obliteration rate and postoperative pain after treatment of the saphenous vein with 1470nm laser or VNUS Closure Fast (=radiofrequency method) .
To establish if there are venous obstructions in patients with neurodegenerative disorders
Volumetry is essential for the diagnosis and follow-up of patients with limb edema. The objective of this project is the validation of real-time reconstruction and calculation of limb volume using a 3D laser scanner. Water - displacement volumetry (water-filled boot) is the reference method with known accuracy and reproducibility, but is not commonly used in clinical practice because it is cumbersome, difficult, and time-consuming. The most commonly used method remains segmental limb perimetry with a tape measure, followed by volume calculation using the truncated cones formula, thus excluding de facts extremities (hands and feet) which can neither be likened to cones nor easily measured. Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches. The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches. The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with real-time 3D reconstruction. Its advantages are non-contact, accurate and detailed quantification of edema, including extremities, allowing to assess the magnitude and topography of physiological, pathological, or treatment - induced volume changes. This approach will ultimately provide data that will used for designing personalized limb compression ortheses.
