Sapheon Glue
A recently approved modality that uses a bio-compatible to seal the saphenous vein not yet reimbursed by insurance companies.


Sclerosant
A term used for the solution used to do sclerotherapy for spider veins. FDA approved solutions are Sotradecol & Polidocanol. Other solutions doctors might use are glycerin and solutions that contain dextrose. Saline is rarely used since the effectiveness is low and it causes pain.


Sclerotherapy
Sclerotherapy is the injection of a sclerosing solution into a vein that causes thrombosis of the vein and eventual resolution.

Skin Ulcer
A small sore that rarely occurs after sclerotherapy. Most heal spontaneously but, sometimes a small excision is needed.
  -- Subcutaneous injection of liquid and foamed polidocanol: extravasation is not responsible for skin necrosis during reticular and spider vein sclerotherapy


Small Saphenous Vein
(SSV) The small saphenous vein is located in the back of the leg. The vein starts at the crease in the knee and runs down the back of the calf and angles to the outside of the foot. This vein is responsible for varicose veins in 10% of patients. Varicose veins are located on the back of the calf or thigh. The vein empties into a deep vein called 'popliteal'. The popliteal vein is the main deep vein in the knee area. -- Also called: Short Saphenous Vein, Lesser Saphenous Vein


Sotradecol
Sotradecol (sodium tetradecyl sulfate) Injection is a sclerosing agent used by vein specialists to treat spider veins.


Spider Vein
Small red and bluish veins located just beneath the skin surface. Spider veins are usually associated with higher venous pressure in the reticular venous system. They can be associated with hormonal changes, pregnancy, heredity, and reflux in the deeper venous system.

Staining
Staining refers to a brownish discoloration and often times seen after sclerotherapy treatment. This represents the iron pigment in the blood and resolves in most cases in a few weeks or months.
  -- Cutaneous hyperpigmentation following venous sclerotherapy treated with deferoxamine mesylate.


Stasis Dermatitis
Refers to the pigmentation that occurs in the skin after long standing venous hypertension.


Stripping
The saphenous vein is removed by using a small wire that is passed from the groin to below the knee. This is rarely done now due to newer techniques.
  -- Stripping the long saphenous vein reduces the rate of reoperation for recurrent varicose veins: five-year results of a randomized trial.


Suborbital Veins
Refers to the vein underneath the eye that becomes dilated in some patients.


Superficial thrombophlebitis (SVT)
Inflammation of a vein due to a blood clot in a vein usually located in veins near the skin surface. -- Also called: superficial vein thrombosis


Superficial Vein
Veins that are located closer to the skin above the muscles of the thigh and lower leg. In most cases, superficial veins are responsible for the bulging veins called varicosities.


Swelling
Increase fluid in the lower leg and gives a feeling of tightness or heaviness.
