International Society for the Study of Vascular Anomalies (ISSVA)
The International Society for the Study of Vascular Anomalies (ISSVA) is the formalization of prior biennial international workshops, which were started in 1976 by Drs. John Mulliken and Anthony Young, of specialists interested in the diagnosis, management and investigation of these disorders. ISSVA was officially founded in 1992, two years after its first International Workshop held in 1990 in Amsterdam. The basic concepts behind the workshops has been maintained over the years as the field burgeoned around the original classification of vascular anomalies developed, revised and codified by ISSVA.
