Overview

Vascular malformation is a blood vessel abnormality. There are many types, but the most common is arteriovenous malformation. It may cause aesthetic problems as it has a growth cycle and can continue to grow throughout life. This is also known as Vascular giantism or lymphangiomas.

Simple Vascular Malformations

Simple Vascular Malformations are divided into:

• Capillary malformation
• Lymphatic malformation
• Venous malformation
• Arteriovenous malformation
• Arteriovenous fistula
