Varicose Veins are permanently dilated veins through which blood circulates with difficulty or not at all.

Frequent causes are: heredity (most common), pregnancy, heat, and standing positions for long periods of time.

An evolving disease, patients who suffer from venous disorders should be aware that only a continuing treatment can control the evolution of the disease.

Elastic stockings must be worn to compress the lower extremities, stopping the swelling of the legs and formation of new varicose veins. Stockings should be put on before getting out of bed or else lift up legs 2-3 minutes, and then pulled on.

The sclerosing agent injected in varicose veins collapses the incompetent vein in 1 to 3 months. Blood circulation is restored through normal veins.

Surgery is often indicated in the treatment of varicose veins. All incompetent veins, however, are not eliminated by this method, which must invariably be followed by sclerosing therapy.

Pain tends to disappear and the aesthetic appearance of the legs improves after a brief 3 or 4 sessions.

Injections in the areas of the knees, ankles, and feet may cause oedema (swelling); however, this problem rapidly disappears.

Each session lasts 15 to 20 minutes, and most patients can expect to see 80 to 90 percent improvement.

Ecchymoses (bruises), either very small or large, occur frequently during treatment and disappear within four weeks.

Small Red Spots may be caused by the injection of small varicosities; they disappear within 3 weeks.

Tender red cords: this is not phlebitis! Occurring occasionally, this is light inflammation which reduces through brisk walking and application of warm wet gauzes. Do not hesitate to call us if you are worried.

Staining of the skin: In rare instances, the skin remains a darker colour in some areas and takes longer in regaining its normal pigmentation; some spots may even be permanent.
Small telangiectasia (spider veins) may appear after injections of large veins in a few patients. However, such telangiectasia will be treated afterwards and will disappear with time.

Allergic response to the sclerosing agent: In spite of the detailed questionnaire you are required to answer, it is possible that you may be allergic to the sclerosing agent. These rare complications range from a slight tingling sensation and/or red blotches on the skin, to anaphylactic reaction (severe allergic reaction); this rare complication will bring a drop in blood pressure associated with other symptoms demanding further medical attention.
Rare cases of deep vein thrombosis and pulmonary embolus have been reported in medical literature, following injection in the long saphenous vein.

Also, there are two possible accidental complications arising from the sclerosing agent being injected into the subcutaneous tissue or into a tiny arterial vessel. Both complications result in an ulcer eventually leaving a scar.

Do not:
• Do not apply oil or cream the day of your treatment; bandages will not adhere properly.
• Do not wax or shave the day before your treatment.
• Do not take very hot baths, whirlpools, saunas, or massages.
• Do not sunbathe for 48 hours after your treatment.

• Continue your routine as usual with emphasis on exercise (walking, jogging, cycling).
• Wear compression stockings as often as possible during the day.
• Remove tapes 2 hours after treatment while taking a lukewarm bath with oil.
