Varicose Veins Are Not Always Visible to the Naked Eye
Most vein conditions are not visible to the naked eye. The veins that are visible can be the ‘tip of the iceberg’ indicating an underlying problem. Therefore, a duplex ultrasound examination may be recommended to determine if there is an underlying condition called, venous inssufficiency. Venous insufficiency indicates when the vein valves are leaky. Bulging, ropy varicose veins, and spider veins in certain anatomic regions of the body such as the inner ankles and inner thighs or blue veins behind the knees suggest underlying venous insufficiency.
