Varicose veins are enlarged blood vessels that form beneath the skin surface.
The condition is caused by the improper functioning of one-way valves in the veins that would normally channel the blood back to the heart, causing the blood to ‘pool’ in the veins.
This pooling stretches the veins, creating swollen and twisted blood vessels that appear under the skin as blue, rope-like veins.
These veins can become large and unattractive and can produce symptoms such as tiredness, heaviness, aching, burning, itching or cramping legs.
Spider veins are small, thin blood vessels that lie close to the surface of the skin and appear red or blue.
These small, enlarged blood vessels may appear as short, unconnected lines or may be connected in a spider web or cluster pattern.
Spider veins can cover a large area of skin and are unattractive. They commonly occur in the thighs, ankles and feet. At times, they may be uncomfortable.
Sclerotherapy (micro-injection) is a technique which can treat most varicose and spider veins. Tiny needles are used to inject a medication (sclerosing solution) directly into the unwanted vein.
The solution acts on the inner linning of veins, causing it to collapse and shrink so that no more blood can flow through this unwanted vein. Within weeks, the unused vein is absorbed by the body and eventually becomes barely noticeable.
Compression stockings are often required after injection.
Different techniques of injection and sclerosants are employed to achieve a good outcome.
Ultrasound guided sclerotherapy (UGS) is employed to treat leaking valves in leg vein.
