PAVA - Primary Avalvular Varicose Anomalies - are a new sort of varicose vein that have been discovered and described by The Whiteley Clinic research team. Their findings are being published in the Journal of Vascular Surgery Venous and Lymphatic Disorders.

PAVA are small varicose veins, often wrapped around big varicose veins, that do not get treated by normal varicose vein treatments. Failure to identify them and treat them may lead to recurrent varicose veins in the future being erroneously thought of as "neovascular tissue" or the re-growth of veins after varicose vein treatments.
