INTRODUCTION Red blood cells' (RBC) rheological properties are disturbed in chronic venous disease (CVD). The aim of the study was to compare deformability and aggregation of erythrocytes taken from the varicose vein and the antecubital vein of patients with chronic venous disease. MATERIALS AND METHODS Blood samples were taken from twelve CVD patients presenting clinical, aetiological, anato...

The ultrasonic treatment of varicose veins uses high-intensity focused ultrasound, in which a blood vessel is contracted by converting acoustic energy into thermal energy. In this study, we propose a phantom of varicose veins that can be applied for the efficient evaluation of ultrasonic treatment in varicose veins. The proposed phantom consisted of glycerol base tissue equivalent material, ves...

Hemorrhoids and varicose veins are common conditions seen by general practitioners. Both conditions have several treatment modalities for the physician to choose from. Varicose veins are treated with mechanical compression stockings. There are several over-the-counter topical agents available for hemorrhoids. Conservative therapies for both conditions include diet, lifestyle changes, and hydrot...

The prevalence of varicose veins was studied in 504 women cotton workers in England and 467 in Egypt, by a standardized questionary and a specially developed method of examination. The English mill population showed a much higher prevalence of varicose veins than the Egyptian, probably owing to environmental rather than ethnic reasons.Among the European women the prevalence of varicose veins wa...

A simple, precise, and consistent anatomical terminology is necessary for evaluating and treating patients with varicose veins. A clear understanding of the anatomy is also very important to correctly diagnose and perform the best treatment for varicose veins. Because the anatomy depicted by ultrasonography has many variations, anatomic definition for at least some of the veins ...

INTRODUCTION varicose veins are tortuous and poorly contractile. Their aetiology remains unclear. Neovascularisation has been suggested as a possible explanation. Endothelins are mitogenic, promoting proliferation and migration of endothelial cells via endothelin-B receptors. We hypothesise that endothelial cells and endothelin receptor density and distribution may play a role in the developmen...

The role of incompetent perforating veins in the aetiology of varicose veins is not well understood. Anecdotally, competitive cyclists appeared to be more prone to varicose veins than the general population. We present a case of a 63-year-old amateur competitive cyclist who acutely developed a painful varicosity of her left calf while straining during a hill climb in 106-mile cycle race. Duplex...

A patient-specific finite-element (FE) model of the human leg is developed to model the stress distribution in and around a vein wall in order to determine the biomechanical response of varicose veins to compression treatment. The aim is to investigate the relationship between the local pressure on the soft tissues induced by wearing the compression garment and the development and evolution of ...
