Before the 1980s, the classification and naming of vascular diseases at home and abroad have not been uniform, resulting in confusion in clinical treatment, and even now there are still some areas still using the old classification method, some of them using the term “hemangioma” to refer to all vascular diseases. In fact, the so-called “hemangioma” actually includes two categories of hemangioma and vascular malformation, and vascular malformation accounts for the majority, especially the proportion of adult patients is greater. Since the two types of vascular diseases are treated differently, a clear diagnosis can be of great help in treatment. Infantile hemangiomas have the characteristic of spontaneous regression. About 70% of them appear within a few weeks after birth, early as white spots on the skin followed by red patches, then rapidly increasing in size, and gradually fading after the age of one year. The course of a typical hemangioma is divided into three phases: the proliferative phase, the receding phase, and the complete receding phase. Although infantile hemangiomas have a natural tendency to regress, if not treated early, they can leave large scars after regression. Treatment is best started at the time of the proliferating star and can include: sclerotherapy, oral medications, laser therapy, or surgery in advanced stages. Vascular malformations do not have a natural fading process, usually present after birth, but sometimes not obvious, and only gradually manifested later, slowly increasing thickening with age, even until the end of life, so early treatment is also required. Treatment options include: laser therapy, sclerotherapy, embolization and surgery. These methods can be used in combination.
