Methods for the localization of incompetent ankle perforating veins.

A test for localizing incompetent ankle perforating veins uses an injection of fluorescein into a vein on the dorsum of the foot, with subsequent scanning of the leg under ultraviolet light. The test was found to be 96% accurate, and to be simple, safe, and cheap. It is considered to be particularly suitable for assessing legs with very early changes and with recurrent varicose veins.
