Varicose Veins Treatment: Cryosurgery

Cryosurgery is a varicose veins treatment which will employ a cryoprobe introduced in the affected vein. The probe will be frozen and the saphenous vein may be removed totally or partially.

Varicose veins are enlarged veins that typically occur on the legs, but may be visible in other areas of the body as well.


Cryosurgery is considered a variant of vein stripping. The procedure is surgical and will be performed using a probe. The probe will be introduced in the saphenous vein and then, the surgeon will apply either NO2 or CO2 and freeze the vein at temperatures around minus 85 degrees. Once the vein is frozen, the vein can be totally or partially removed.

The procedure is similar to vein stripping, but in the case of crysurgery, the additional distal incision to remove the stripper is not needed.

Complications of Cryosurgery

Cryosurgery is a safe procedure than vein stripping, but it may still have a few risks and complications, including:

  • Damage to the nearby health skin tissues
  • Deep vein thrombosis
  • Embolisms
  • Infections and other wound infections

However, cryosurgery is a minimally invasive procedure that will cause minimal pain and discomfort. The surgery will cause minimal scars, which will be less visible than in the case of vein stripping. After a cryosurgery, the patient will experience redness and swelling; blisters may also occur in the area of the procedure. Analgesics will be recommended to relieve the pain that will occur after the surgery.
