Vascular malformations are developmental anomalies that are present at birth but may not be visually apparent. These malformations can be slow-flow (ie, capillary, lymphatic, venous) or fast-flow (ie, arterial). Arteriovenous malformations (AVMs) represent a combination of these elements. Arteriovenous malformations (AVMs) occur equally in males and females. Low flow malformation are much more common than lhigh flow malformations. 3
