Classification of Vascular Malformations

Abstract

As congenital vascular malformations (CVM) are a complex mixture of different vessels, classification is difficult. In the past, different descriptions, syndromes with common names and complex classifications have been used to define these diseases. Only recently, two main classifications, more or less accepted, have been proposed: the Mulliken Classification, based on flow velocity in the defect, and the Hamburg Classification, based on the vessels’ embryological development. Both of these classifications are imperfect. A combination of both may offer the best option to define these pathologies clearly.
