sclerotherapy
Pronunciation: SKLER-oh-THER-ah-pee
Injection of a sclerosing agent into veins to cause closure and elimination of varicose or spider veins.
Full Definition
Sclerotherapy involves injecting chemical sclerosants into abnormal veins to induce endothelial damage, inflammation, and eventual fibrosis leading to vein closure. Common agents include sodium tetradecyl sulfate, polidocanol, and hypertonic saline. The procedure is primarily used for treating spider veins, reticular veins, and small varicose veins. Foam sclerotherapy, where the sclerosant is mixed with air or gas, allows treatment of larger vessels and improves contact time with the vessel wall.
Usage
Usage note: Distinguish between liquid and foam sclerotherapy in documentation.
