Vascular Marlformations

Vascular malformations have been recognized throughout history as birthmarks. Vascular malformations have been categorized using confusing, inaccurate, and inconsistent terminology. A significant number of patients with vascular lesions receive ineffective and potentially harmful treatment based on misclassification.

Mulliken classified vascular malformations using understandable and accurate nomenclature. Vascular malformations are subdivided into low-flow (capillary, venous, lymphatic, or a combination thereof) and high-flow (arterial) anomalies. Clinical, histological, histochemical, and biochemical differences and radiographic imaging findings support this classification.
