Previous Versions:
The glossary is an appendix to the Classification and was created to allow wide access and clarification of vascular anomalies terminology. Its online version is hosted on the ISSVA website. Shortly, there will be hyperlinks within the classification and the glossary, to facilitate cross referencing and enhanced understanding. The document will be updated continuously.
The glossary lists and explains, in alphabetic order, all technical terms, abbreviations, acronyms, eponyms, genes and syndromes related to vascular anomalies. After explanation, each term is accompanied by specific codes meaning its definition, that is, whether it is a technical term (t), an eponym (e), an acronym (a) a gene (g) or a syndrome (s). The glossary therefore forms an important part of the classification. Since it is a living document, it is hoped that glossary entries will also be linked to ‘atlas’ type resources of typical pathology, medical imaging, and clinical images. This should aid not only the proper classification of lesions but also facilitate education and communication for patients and caregivers.
