vascular malformation malformations (VMs) are a group of congenital anomalies characterized by abnormal development of blood vessels. Unlike hemangiomas, which are benign tumors that grow and vascular malformation then regress, VMs are present at birth and do not typically regress. They can range from small, inconspicuous lesions to large, life-threatening conditions. This article will explore the various types of vascular malformations, their clinical manifestations, and the available treatment options.
Types of Vascular Malformations
Vascular malformations can be classified into several categories based on their underlying vascular structure:
Capillary malformations (CMs): These are the most common type of VM and are characterized by dilated superficial capillaries. They can appear as red or purple birthmarks and may be flat or slightly raised.
Venous malformations (VMs): These are composed primarily of dilated veins. They can range from soft, blue masses to hard, painful lesions.
