Varicose Vein Treatment options

How are varicose veins treated?

The removal or otherwise treatment of varicose veins does not cause circulation problems in the limb, because veins can re-route themselves. Venous flow with in the varicose vein is already compromised, with poooling and reverse flow, so there is no detrement to blood circulation in providing treatment.
Minimally and non-invasive treatments options for varicose veins include:
  •    Compression stockings  
  •    Injection therapy (Foam and microsclerotherapy)
  •    VNUS® Closure (Radiofrequency ablation)
  •    EVL (endovenous laser therapy)
  •    SEPS/RFS (Sub endo-scopic perforator surgery /Radiofrequency Stylett)
Choice of treatment should always be individual to the patients' needs, incooperating one or more of the above procedures, dependent on the findings of an investigative Ultrasound scan and the patinets wishes.
Compression Hosiery 
Also called support stockings - these reduce symptoms, by putting pressure on the leg muscles that squeeze the veins, thus improving the flow of blood back to the heart. Hence, there is less swelling, tiredness, and achy feeling. Good compression hosiery provides 'graduated' compression, being maximum at the ankle and reducing up the leg.
An injection therapy, it may be used to close off damaged veins without the need for surgical removal. Microsclerotherpy is used in this way to treat thread veins.
Using a fine needle, an irritating chemical (the sclerosing agent) is injected into the varicose vein. The sclerosing agent creates scar tissue inside the vein by causing a chemical burn, which blocks off the flow of blood to that vein, shutting it down.
VNUS® closure
The VNUS® Closure technique involves inserting a catheter into the defective vein through a small skin puncture. Radiofrequency energy is then applied to the vein wall via this catheter, causing the vein to shrink and seal shut.
The VNUS® Closure technique is a minimally invasive procedure. It can be performed in a clinic room with the patient able to resume normal activity immediately after treatment. Bruising, a common side effect of any invasive procedure, is minimal.
Endovenous laser treatment
Also called "EndoVenous Laser Ablation" or "EVLA". EVLA was introduced in 1999 and is performed in a fashion similar to VNUS® closure. Ultrasound imaging is used to guide the insertion of a laser fibre into the varisoce vein. This is introduced through a very small incision.When the ultrasound shows that the EVLA laser fibre is in the correct place, the laser is activated. The laser light heats the blood almost instantaneously, as a pulsed light source forming steam bubbles. These bubbles transfer the heat to the vein wall, destroying it and causing the vein to close.

About half the patients with varicose veins have “perforating veins”. These are veins that connect the deep veins with the surface veins. Usually they should pump blood inwards. When they go wrong, these perforating veins allow blood to shoot outwards and into the varicose veins. 
Perforating veins can be removed by using a procedure where a small Radiofrequency stylette is guided directly into the perforating vein using ultrasound guidance and radiofrequency energy is transmited the same as VNUS® closure in order to close the vein down.
