Varicose veins are enlarged veins that are greater than 2 millimetres in width and sometimes exceed 2 centimetres. They may appear blue or green in colour but often no colour is seen. In this latter circumstance, they just appear as protruding, tortuous cords that course under the skin. Varicose veins are apparent when standing but often seem to disappear when lying down or with leg elevation. A normal vein has one-way valves (known as venous valves) which ensures the unidirectional flow of blood. A varicose vein has incompetent valves that are not able to prevent blood from pooling within its channel. Without treatment, the continued pooling of blood causes these veins to become even more distended. Surgery may be required for large varicose veins.
Dilated Capillaries (also referred to as broken capillaries, broken veins, or broken blood vessels) appear as red or pink thread-like lines, usually less than 0.2 millimetres in width. However, when a large number of capillaries are clustered together they may have the appearance of a red patch or a bruise that never disappears. Besides the legs, they are often seen on the face and nose. Unlike the slightly larger spider veins, dilated capillaries respond poorly to Sclerotherapy. The safest and most effective treatment is with an Nd:YAG laser treatment.
Spider veins, or telangiectasia, are those tiny purple and red blood vessels and are defined as distended veins less than 2mm in width. It is found most commonly on the thighs or lower legs of women. They are hereditary and can form anywhere on the leg, from the top of the thigh to the ankle. While often flat, they may protrude, especially during standing. Occasionally, spider veins appear on the face. The most effective non-surgical treatment is by Nd:YAG laser treatment.
Sclerotherapy treatment was developed in the 1920s. During the procedure, a sclerosing solution is injected into the vein through a micro needle. The tiny needle generally causes very little pain. The sclerosing solution causes the vein to blanch (turn white) then gradually disappear.
Prior to treatment, we will review your complete medical history to determine how long you have had a problem with your veins and the severity of the problem. We need to know if the problem is exacerbated by physical activity and if there has been any prior surgery or treatment on your veins.
First, we will thoroughly cleanse the area to be treated. Then we mark the veins to be treated while you are standing. Using a tiny syringe fitted with micro-needle, your physician will inject a small amount of sclerosing agent into the veins. It then causes irritation to the lining of the vein, making it swell. The treated veins will then gradually disappear.
Most patients will experience a little discomfort of a mild burning sensation when we inject the solution, which will then stops after few seconds.
For best results, more than one treatment is required. In most cases, about 50%-70% of the treated vessels or veins will be gone permanently. However, new veins may appear and additional treatments are required for optimum results. These treatments may be in 4-week intervals.
Patients are refrained from vigorous activities for the first 24 hours. Walking is encouraged as it increase blood flow through the other veins. Most patients experience a 60% to 80% improvement.
Today’s new medical laser provides a safe and effective non-surgical treatment option for the removal of some spider veins. During your treatment, light energy is delivered to the targeted vein. The light energy is then absorbed by the blood vessels, but not the surrounding tissue. This causes a coagulation of the blood vessel, which is subsequently absorbed by the body. It is best to consult our professional practitioner or cosmetic nurses for a full assessment and to discuss the suitability of each treatment.
