Leg thread veins
Also called thread veins or broken veins, these are very common. Almost 50% of adults are affected and therefore many people are interested to know how to get rid of these unsightly blemishes. People with thread veins fall into one of two categories, and in the majority of cases there is a problem with the valves of the superficial veins – either in the large saphenous vein, or else in the smaller reticular or feeder veins. This is why it is very important to get a duplex ultrasound scan before deciding how to treat spider veins. A duplex scan will identify which veins have faulty valves and how best this can be put right. For the remainder of those with thread veins, there may be aggravating factors but the cause is not known. These leg thread veins are said to be idiopathic. A duplex ultrasound scan is needed to make sure that people with leg spider veins are classified correctly so they get the correct treatment.
Those with vein reflux should have this treated first. This may mean endo-venous laser for the unhealthy veins. Typically, this is performed under a local anaesthetic as a walk in walk out procedure. Endo-venous laser has replaced surgical stripping as it is much less invasive and gives much better results with no scarring. Once the larger unhealthy veins have been dealt with, then the smaller feeder veins and thread veins can be injected – a treatment called microsclerotherapy
