The German Interdisciplinary Society for Vascular Anomalies (GISVA) is a German non-profit association of medical experts from 10 different disciplines dedicated to the diagnosis, differential diagnosis and treatment of vascular anomalies and vascular tumors.

Our endeavor is the interdisciplinary exchange of knowledge across disciplines and the dissemination of knowledge in the field of vascular malformations and vascular tumors including hemangiomas. Our broad medical knowledge database on vascular anomalies is a freely accessible internet encyclopedia. It is growing steadily thanks to a large professional authorship, is being constantly updated and contains a large inventory of case-related data.

Please be aware that it is not possible for us nor intended to directly consult patients. A list of medical experts in interdisziplinary centers may e. g. be found at Federal Association of Congenital Vascular Malformations (Bundesverband Angeborene Gefäßfehlbildungen e.V. –
