A 40-year-old woman presented with large bulging veins in both thighs and lower legs. Her primary concern was the unsightly aesthetic appearance of the varicose veins but on further questioning, she revealed that she was experiencing heaviness, tiredness and throbbing in the lower legs. She worked as a medical assistant, which involved constant standing for hours, at daily basis. By the end of the day, her legs were extremely fatigued, and it would take several hours of leg elevation to make them feel better. There was no past medical history of deep venous thrombosis. Duplex Ultrasound examination revealed a varicose great saphenous vein bilaterally running from the groin to the mid-distal thigh. Examination of the deep veins of both lower limbs showed no evidence of occlusion in the external iliac, common femoral, popliteal, anterior and posterior tibialis, and peroneal. Which of the following mechanisms is most likely to explain the patient's findings?    Group of answer choicesFailure of arteriovenous anastomosesFailure of venous valves in the deep veinsPredominance of smooth muscle cells of a synthetic phenotype in venous wallsMutation of the vascular endothelial growth factor receptor 3 geneDysfunctional endothelium producing increased levels of vasodilatory mediators
