Epidemiology of Vascular Malformations

Vascular anomaly comprises a wide spectrum of lesions as an outcome of disorders in vascular development. They continue to be a challenge in both diagnosis and treatment and need individual and multispecialty treatment program. The key to proper treatment of these lesions relies on correct diagnosis and classifying the vascular lesion. The vascular anomaly can be described by two abnormal vascular conditions: the congenital vascular malformation (CVM) and the vascular tumor that represents neonatal or infantile hemangioma. Both conditions are different in their anatomical, histological, and pathophysiological findings and also in their clinical courses, which emphasizes the importance of a precise understanding of these two conditions.
