Despite tremendous efforts to control the CVMs through centuries, it has remained a significant challenge to clinicians and the CVM is often viewed as an enigma among the vascular disorders. Besides, old definition of the CVMs based on only the clinical findings and also the classification with name-based eponyms through the last century added more confusion and failed to provide proper information necessary for its advanced management. Through last two decades new classifications have been established to meet its mandate for the contemporary management: Hamburg Classification and ISSVA Classification. Both classifications were established based on new advanced knowledge of the anatomy, embryology and pathophysiology involved to the CVM pathogenesis as birth defects affecting entire vascular system: artery, vein, and lymphatics. The role of old classification became obsolete, no longer needed for contemporary management of the CVMs. Hamburg Classification is now able to provide safer clinical guide based on embryological characteristics of the CVM le...
