Investigation Into the Pathophysiology and Treatment of Varicose Veins

Varicose veins affect up to 40% of the population and are associated with significant discomfort, skin damage, and complications including ulceration and perforation. In recent years, there has been a move towards minimally invasive treatment, including chemical sclerotherapy. Despite their widespread use,the fundamental effects of sclerosants have not been fully characterised. Furthermore, their use is associated with significant rates of re-canalisation and clinical recurrence. There is therefore significant scope for researching the effects of sclerosants on the vein wall and the mechanisms of cell death. Furthermore, the pathophysiology of varicose veins has not been fully characterised. It is the aim of this study to research a number of themes related to the use of sclerotherapy and the pathophysiology of varicose veins in order to provide information which will both further scientific knowledge and further develop clinical practice by optimising the use of sclerotherapy. This research will be conducted by a PhD student based at the University of Surrey, in conjunction with the Whiteley Clinic in Guildford. Veins and blood samples removed following varicose vein surgery at the Whiteley Clinic will be provided for laboratory-based research at the university. A range of methodologies will be employed to analyse cellular responses to sclerosants to determine the precise structural and biochemical changes which lead to destruction of the vein and clinical efficacy, and to investigate a number of key themes implicated in the pathophysiology of varicose veins.
