Varicose veins are elongated, bulged and twisted veins below the skin on your legs that are a darkish blue colour.
Varicose veins are usually a symptomatic of a much more serious disease known as "venous insufficiency". Varicose veins are often accompanied by symptoms including swelling, aching, heaviness, burning, cramping and itching.
Spider veins are the most distal and smallest vein tributaries under the skin which can be dark red or purple colour. Spider veins have the apperance of spider webs.
Spider veins usually signal venous disease and are connected to larger veins. Aside from their unpleasant apperance, there is no associated serious symptoms with spider veins. Spider veins like varicose veins are usually hereditary.
Endovenous laser ablation (EVLA)
Endovenous laser ablation (EVLA) is an ultrasound guided, minimally invasive procedure which uses controlled heat from a laser to cause a collapse and sclerosis on the varicose vein wall.
The skin incision is 2-3 mm deep and the procedure is done under local anesthetic.
Sclerotheray is an effective minimally invasive procedure which has been used for several decades to treat spider veins and small varicose veins tributaries.
Sclerotherapy involves injecting a solution into the varicose vein under direct vision or under ultrasound guidance.
