What is Sclerotherapy?

Sclerotherapy is done with injections to improve the appearance of small varicose and spider veins. This treatment is effective but not curative and so might need to be repeated periodically. For more information about sclerotherapy and varicose vein treatment please visit our beauty spa clinic in Richmond Hill.

What Is a Varicose Vein?

Varicose veins are most commonly found in the legs and affect superficial veins. A varicose vein usually looks torturous, swollen, and uneven, and is caused by blood pooling due to vein valve insufficiencies. Small blue varicose reticular veins are good candidates for sclerotherapy treatment. Spider veins, which are purple to red in colour, superficial, and flat, are usually very responsive to sclerotherapy treatment as well.

Causes of Varicose Veins

  • Pregnancy
  • Prolonged standing, prolonged sitting especially with legs crossed
  • Constricting clothing at the waist
  • Weight gain/being overweight
  • Hormones
  • Hereditary

Symptoms of Varicose Veins

  • “Restless” legs at night
  • Pain, cramps
  • Throbbing legs, tired legs, tingling in the legs
  • Swollen torturous or flat visible superficial veins and spider veins

Sclerotherapy is safe, simple and effective varicose vein treatment

Our Sclerotherapy Procedure in Richmond Hill

Sclerosing irritating agent was injected into the targeted vein. Small vein/vessel walls collapse and scar together to be absorbed by the body in the next several days/weeks depending on the size of the vessel.

It is important to understand that spider veins are fed by reticular superficial veins. Spider veins re-occurrence is rare if feeding reticular veins are addressed with sclerotherapy. Therefore, sclerotherapy is considered to be the best and the most effective minimally invasive procedure as compared to other treatment modalities such as laser for closure and elimination of both spider veins and feeding small reticular veins. Large varicose veins, more than 3 mm in diameter, are not appropriate for sclerotherapy and are best treated by surgery.

For sclerotherapy, the most common sclerosing agent for injects is Sclerodex, which is essentially a sterile hypertonic solution containing salt and sugar molecules. Very gentle but effective treatment. Treatments may need to be repeated to achieve the best results.

Different types of veins that can be treated with sclerotherapy:
