This is usually defined using duplex ultrasound which can measure flow in individual veins. Refluxive veins are defined as reverse flow in a superficial or saphenous vein which lasts more than half a second. Refluxive deep veins are defined when this reverse flow lasts more than 1 second. The normal direction of flow in a vein is… Read More »
This is an abbreviation for Ultrasound-Guided Foam Sclerotherapy. It is a common method used for treating varicose veins. It can be used for destroying the varicose veins themselves as well as the saphenous veins which are usually the main veins responsible for causing varicose veins. A detergent is mixed with a gas to produce the foam.… Read More »
This is an abbreviation for Endo-Venous Laser Ablation. It is a widely practiced technique for treating varicose veins. It is usually performed using a local anaesthetic whilst the patient lies on an operating table. A laser fiber is inserted along the length of the saphenous vein, which is usually the main vein from which varicose veins arise. Before firing… Read More »
Phlebitis is characterised as a localised inflammation of a varicose vein when the flowing blood within this vein has thrombosed. It is clinically apparent as a hard indurated cord, tender to touch, with evidence of surrounding inflammation. It is part of the condition of superficial vein thrombosis. Duplex ultrasound is mandatory to screen for a concurrent… Read More »
This could be defined as an impairment of the venous drainage of the leg at a local or regional level. It is parallel to arterial insufficiency which is impaired supply to tissues and organs. These are both haemodynamic terms. Whilst it is relatively easy to quantify arterial insufficiency, venous drainage is much harder to measure. Causes include… Read More »
