Microsclerotherapy is considered the gold standard in treatment of spider veins of the legs.
This technique is suited to the treatment of fine spider veins and reticular veins, mainly for cosmetic reasons.
A very fine needle is inserted into the small vessels and a hardening agent (called a sclerosant, usually Sclerovein or 20% Hypertonic Saline), is injected to close the vessels off. The procedure is usually reserved for small blue superficial veins (reticular veins), spider veins, and sometimes for small visible varicose veins. Successfully treated veins will fade as the body gradually removes them. Generally, normal activities can be resumed straight after sclerotherapy. Medically prescribed compression stockings must be worn for a week after treatment to achieve the best outcomes. Walking each day post treatment is recommended.
Each leg may require several treatments in order to achieve an acceptable end point. Yet this treatment, despite the availability of lasers, is still the best treatment for leg spider veins and reticular veins.
Risks from this treatment are relatively rare and mild, reflecting the dilute strength of the sclerosants used. Recurrence of further vessels with time, mild staining, and ulceration are all potential problems. However, ulceration is fortunately a rare complication in experienced hands.
The procedure is performed in a consulting room and usually causes minimum temporary discomfort.
Are there any other treatments for spider veins?
Certain vascular lasers and IPL (intense pulsed light) machines can improve spider veins and reticular veins, but these treatment modalities are best suited to spider veins on the face. Treatment of spider veins on the legs with laser and IPL can help but the results are inconsistent and disappointing. Microsclerotherapy remains the best treatment for spider veins on the leg.
