Ultrasound guided sclerotherapy or UGS is a modern technique to treat varicose veins. Varicose veins occur when the valves in your veins fail, blood pools and the resulting pressure dilates the veins. The only treatment for these veins used to be painful invasive surgery. UGS involves injecting the vein with a sclerosant, which is a substance which makes the vein walls ‘sticky’.

The vein adheres to itself (called occlusion), closes and forms scar tissue which is absorbed by the body over time. The procedure is ‘Ultrasound Guided’ because the treating practitioner uses an ultrasound machine to image the vein and guide their injections. This means that they can see all the parts of the incompetent (failed) vein and treat even the very small branches. There is no cutting of the vein and this procedure is literally ‘walk-in walk-out’ you can go back to work the same day.

Compression stockings need to be worn for two weeks after the procedure and you need to walk for 30min per day. This procedure is particularly effective for recurrent varicose veins after vein surgery. Recurrent veins tend to form a network of small veins making a second surgical intervention difficult, these smaller networks can be seen and treated easily with the guidance of the ultrasound.

Also most people who have had surgery don’t want to go back! This excellent technique eliminates the need for hospital admission, general anaesthetic and weeks off work. It really is the way of the future for varicose vein treatment. No longer suffer with the pain and discomfort of varicose veins, be treated quickly and effectively to regain that much needed boost in your quality of life.

Varicose veins are caused by the one-way valves in your veins failing and letting blood flow the wrong way. That is- back down the leg. This increased blood flow creates more pressure on the vein and eventually it dilates and forms a varicose vein.

The only way to treat varicose veins used to be with vein surgery, also known as ‘stripping and ligation’ this painful operation needed to be done is hospital with a general anaesthetic and you required two weeks off work after the procedure. There is now available in Australia a relatively new technique called ‘Endovenous Laser Ablation’ or ELA.

This technique involves inserting a laser fibre in to the incompetent (failed) vein and using the light energy to ‘heat seal’ the vein. The vein walls stick together and form scar tissue. This is then absorbed by the body over time. There is no cutting, no hospital admission, no general anaesthetic and you can be back at work the next day. The long term results for ELA are also much better than for the traditional stripping procedures.

At five years’ post surgery about 40% of people will have recurrent varicose veins. At five years’ post ELA less than 1% of people will have had a recurrence. Compression stockings must be worn for two weeks after ELA. This procedure represents the way of the future for vein treatment and in the USA has become the treatment of choice for varicose veins, with more ELA procedures being performed than traditional surgery. For anyone with varicose veins ELA represents a more comfortable, less disruptive procedure with a much better long term outcome, which can benefit you in a range of positive ways.

Veins are vessels which are designed to carry de-oxygenated blood back to the heart from the tissues of the body. However, varicose veins are abnormally dilated veins that cannot perform their function.

Varicose veins are larger veins that bulge above the skin surface. They are commonly found in association with larger and deeper vein problems. If there is a deeper vein problem can be detected at an initial examination.

Dilated blood vessels often cause aching especially after prolonged standing. Although dilated blood vessels do carry blood, they are not very efficient and are often not necessary to the circulatory system. The body already has an established alternative route for the blood to travel back more efficiently to the heart (deep venous system). Varicose veins can therefore be treated without damaging circulation. In fact, treatment actually improves venous circulation.

There are a number of factors that can add to the appearance of varicose veins and spider veins. In a number of cases, the veins are caused by weak valves which create insufficient blood flow. This leads to the appearance of varicose veins.

Varicose veins occur in both men and women. A definitive cause is not known, however a strong family history suggests that some people inherit veins that are more likely to deteriorate. In women, oestrogen may play a role as the onset of puberty, pregnancy and taking oral contraceptives can give rise to vein abnormalities. In pregnancy, the enlarged uterus can restrict blood flow from the legs and promote the development of varicose veins. Spider veins and varicose veins are also associated with obesity. Occupations involving prolonged standing tend to increase the likelihood of veins to develop.

Leg Veins are faced with the difficult task of taking the blood up to the heart against the pulling force of gravity. To do this the leg veins depend on the contraction of the calf and thigh muscles to pump the blood. This is why walking is good for your circulation.

So when you walk, the contraction of your leg muscles pumps the blood up. However, as the saying goes "what goes up must come down" which is what happens to blood in the leg veins. Therefore, to prevent the blood from falling back down, nature has designed valves in the leg veins which open in only one direction: upwards. So the valves allow the blood to get through but when it comes back down, the valves shut and stop the blood going all the way down. The next contraction sends the blood even higher until it eventually reaches the heart. 

In venous disease, the underlying problem appears to be damage to the valves. The abnormal reticular veins, for instance, act as "feeders" of the spider veins . The blood flow in these feeder veins can be compared to a "two-way" street. In other words, blood in the feeder veins can go back and forth. This backward flow through the incompetent valves dilates up the smaller veins (medically called "post-capillary venules"). These dilated post-capillary venules are commonly referred to as "spider veins".

The same principle applies to varicose veins. The abnormal valve cannot stop the blood from rushing back down. The blood in these veins is oxygen low and in fact carries a lot of toxins. In the case of varicose veins, the increased pressure in the veins stimulates nerves in the vein wall, leading to aching, cramping and ‘heavy legs’ at the end of the day.

Varicose veins serve no useful function to the body’s circulation.

They do not return blood to the heart and our body has already established alternative pathways to bypass the abnormal varicose veins. When varicose veins are closed down, the circulatory system improves, as do many of the symptoms.

It is important to understand that varicose veins can be a progressive condition and that new veins can develop with time. Ongoing maintenance treatment is likely for most patients.
