This minimally invasive procedure is used to treat spider veins. A solution of various concentrations, called tetradechol, is injected into the vein. This procedure varies in time depending on the size of the veins. This procedure takes approximately 30 minutes, and requires only the wearing of support hose or stockings for several days following the treatment to optimize its effects. The number of treatments necessary varies based on the number of veins and their size. For the best results, sclerotherapy treatments are usually scheduled 4-6 weeks apart.
How successful is sclerotherapy?
Most patients have satisfactory results following their treatment plan. Some patients may notice that their legs look worse before they look better. This is common. Positive results are usually visible within 4 weeks following the first treatment.
What are the side effects?
As with any procedure, there is always the possibility of side effects. Some of the most common side effects include:
- Tenderness - the veins may be tender to the touch after treatment and an uncomfortable sensation may run along the course of the vein. This discomfort is usually temporary.
- Some patients complain of an itchy sensation after treatment.
- Firmness in the treated area can occur and is minimized by the use of support hose.
- Trapped blood may cause a discoloration, although this may leave hyperpigmentation up to one year
- Transient Hyperpigmentation - Approximately 20% of patients who undergo sclerotherapy notice discoloration after treatment. This usually fades in several months. There is a 1% chance of hyperpigmentation continuing after one year.
- Patients frequently notice a brown discoloration, which
fades in a couple of months - at most within a year.
In rare instances the following side effects may occur:
- Skin Ulceration - this occurs in less than 1% of patients who receive sclerotherapy. A blister may form, open and become ulcerated. Healing occurs slowly over a few months. After healing, a scar may be present.
- Allergic Reaction - very rarely, a patient may have an allergic reaction to the sclerosing agent. The risk of this is greater in patients who have a history of allergies.
- Deep Vein Thrombosis - this very rare complication is seen in approximately one out of every 10,000 patients treated. The dangers of phlebitis include the possibility of pulmonary embolus (a blood clot carried to the lungs) and post-phlebitic syndrome, resulting in a permanent swelling of the leg.
