Perforating Vein Sclerotherapy

Another source of venous reflux into varicose veins is through perforating veins. These veins are channels between the deep venous system and superficial venous system, seen primarily in the calf of the lower leg. These perforating veins can be closed with a technique called ultrasound-guided foam sclerotherapy.

Ultrasound-Guided Foam Sclerotherapy

Using a small needle, a mild chemical solution that causes the vein to close is agitated and then injected into the perforating vein using real-time ultrasound as guidance. This treatment causes minimal discomfort during injection. The procedure takes only a few minutes. A compression stocking is then applied after the treatment.

Sclerotherapy FAQs

What is the treatment like and how long does it take?

After your evaluation, a treatment plan will be suggested. We will discuss with you the estimated number of treatments. This depends upon the type and extent of the varicose or spider veins to be treated. It is important to remember that the number of sessions can be only estimated, since every person responds differently to sclerotherapy. A treatment session is about 30 minutes. A very fine needle is used to inject the veins with a small quantity of a chemical solution which involves multiple injections sites.

Is the Procedure Painful?

In general, the only discomfort associated with the procedure is caused by the tiny needle sticks.  The injected solution might cause a slight itching sensation.  Any discomfort is will be relieved by wearing the compression stocking.

When can I expect to see results?

Although some people see results almost immediately, it can take weeks for the veins to resolve completely. With spider vein treatments, the veins often will turn red, and bruising may occur at the injection site. This initial reaction usually goes away within seven days and then the veins slowly disappear over the next two to four weeks. When larger veins are treated by injection, it is normal to see some discoloration and bruising at the injection site and along the vein redness and slight soreness are also common, but not worrisome.

How successful is sclerotherapy?

After 2 to 3 treatments, most patients can expect 50% to 90% improvement. However, fading is gradual and disappearance of spider veins is usually achieved after 6 to 12 weeks.

Who should not be treated?

Patients should wait at least three months after pregnancy or major surgery before being treated for vein disease. Persons with deep vein thrombosis or incompetence, and patients who cannot ambulate for other reasons are NOT good candidates for treatment.  Veins that have been treated with sclerotherapy should not be exposed to sun for 3 weeks after injections.
