Varicose Vein Treatment
Sclerotherapy is normally used to treat small varicose veins including thread and spider veins.
It’s a technique where a liquid, often foam, is injected into a vein, to destroy it. It’s sometimes referred to as ultrasound-guided foam sclerotherapy as it involves injecting special foam into your veins using ultrasound guidance. The foam causes the vein to scar and forces blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades.
The procedure is performed under local anaesthetic and it’s possible to treat more than one vein at a time. After sclerotherapy, your treated veins should fade within a few weeks and within a month you should see the full results. In some instances, you may require sclerotherapy treatment more than once before the vein fades, and there is a chance the vein may reappear.
Endonvenuous laser therapy (EVLT) or endovenous laser ablation (EVLA) is often the first line of treatment for varicose veins. It’s a simple procedure that involves using laser to seal the affected veins.
The procedure is normally carried out under local anaesthetic and involves the insertion of a catheter into your vein using ultrasound guidance to ensure it’s in the correct position. A tiny laser is passed through the catheter to the top of your varicose vein. The laser delivers short bursts of energy that heat up the vein and close it. The laser slowly moves along the vein and seals its entire length.
Following the procedure, your legs might feel tight and you may have some bruising and pain around the treated area.
Varicose vein surgery
If sclerotherapy and endothermal ablation treatments are unsuitable for you or, you’d like your problem vein fully removed, surgery may be recommended. Most frequently you'll be offered a surgical procedure called ligation and stripping to remove the affected veins.
Varicose vein surgery is normally performed under general anaesthetic and it usually takes about an hour to operate on one leg. During surgery, your surgeon will make an incision in your groin and the back of your knee or ankle. They will tie and seal the top of your vein and pass a thin flexible wire through the bottom of the vein and carefully remove it.
Vein removal doesn’t affect your blood’s circulation as it will flow through other veins instead.
