The Background
Sclerotherapy is a proven procedure with a long history of excellent results in eliminating smaller varicose veins and spider veins.

Research shows that up to 50%-80% of injected veins by experienced physicians may be eliminated with each session of sclerotherapy. Less than 10% of patients do not respond to the injections in which case there are alternative solutions.

Generically, spider veins respond in three to six weeks … three to four months for larger veins. Veins that respond to the procedure will not reappear. However, new veins can later surface at the same place requiring additional injections.

Pregnant or bedridden patients cannot have the procedure. If a history of blood clots, your Vein Specialists physician will determine if sclerotherapy can be performed.

The Procedure

• Patient preparation: To begin, anti-inflammatory medications like aspirin and ibuprofen (i.e. Advil, Motrin and Nuprin) should not be taken 48-72 hours before sclerotherapy. Tetracycline, an antibiotic, should not be taken 7-10 days prior. No lotion should be applied to the legs before the procedure.
• The procedure: A mild sclerosant is injected through a very fine needle directly into small varicose veins and spider veins. Patients may experience only mild discomfort.
  • The solution irritates the lining of the blood vessel, causing it to swell and stick together. Over time, the vessels become scar tissue and subsequently fade away.
  • The size and location of the veins, and a patient’s general medical condition determine the number of injections in one session. Sclerotherapy is usually a 30-minute procedure.
• Post-procedure: After the treatment, the patient will need to wear compression stockings and avoid aspirin, ibuprofen or other anti-inflammatory medications for at least 48 hours - Tylenol may be used if needed. Applying compresses, hot baths, whirlpools or saunas, and direct sunlight on the injected areas should be avoided for 48-hours.
  • Showers are permitted, but the water should be cooler than usual. The injection sites may be washed with a mild soap and tepid water.
  • Patients will be able to drive themselves home and resume their regular daily activities. Walking is encouraged.
• Possible, mild side effects can include: itching, raised red areas, minor allergic reaction, and bruising at the injection site. These should disappear within a few days. Other possible side effects for larger veins might include the feeling of hard lumps (may require several months to dissolve and fade); brown lines or spots at the vein site (they should disappear within three to six months), and the temporary appearance of new, tiny blood vessels in the days or weeks after the procedure that will fade within three to twelve months without further treatment.
  • Should inflammation occur within five inches of the groin … a sudden onset of a swollen leg, or formation of small ulcers at the injection site occur, contact your physician immediately. Our practice maintains access to a Vein Specialist physician 24/7.
