About
The aim of the study is to evaluate the efficacy of non-invasive echotherapy for the treatment of varicose veins, within local population, using the Sonovein® device. The quality of life scores at baseline, 2 weeks, 3 months, 6 months and 12 months will be assessed using the EQ-50D, AVVQ and CIVIQ scores. Patient satisfaction at these time points will also be assessed.
Full description
Sonovein® is a unique echotherapy solution, combining therapeutic ultrasound and ultrasound for monitoring. The high-intensity ultrasound beam is focused on the vein through a magnifying glass. As thermal energy is delivered, the thermocoagulation property of ultrasound energy affects the vein wall, causing shrinking and collapsing of the target vein. Thus creating a fibrotic seal and occluding the vessel. The treated vein is immediately closed after the procedure, and its diameter will continuously reduce over time, becoming a fibrotic chord. The treatment along the vein is steered automatically via a touch screen monitor. In-beam linear ultrasound probe allows visualisation of the vein in real-time and insures optimal accuracy. The study involves prospective data collection of 30 patients that will be undergoing HIFU as choice of treatment for their varicose veins / CVI. Questionnaires will be conducted at 5 timepoints - baseline before procedure, 2 weeks, 3 months, 6 months and 12 months. Subjects will be seen at outpatient clinic post-procedure. Besides questionnaires, physical examination and duplex ultrasound scan will be conducted at 2 weeks, 3 months, 6 months and 12 months to ensure occlusion of treated vein.
