Abstract
A method for the eradication of venous blemishes, such as venous "spiders," "sunbursts," telangiectases, venous plexi and groups of dilated venules consists of sclerotherapy employing at least a 20% saline solution with heparin added as a sclerosing agent. The afflicted venules are first partially emptied of blood by gravity and are then completely cleared by forcing small amounts of air through them before they are injected with the sclerosing solution. Chemical burns caused by the caustic effect of extravasated solution on surrounding tissues may be counteracted by injection of water or of a dilute solution of procaine hydrochloride (commonly known as Novocaine) in water.
