2022年7月6日 · Vascular malformations that affect your skin may look like a raised red, blue, purple, brown or black birthmark. These marks may swell, bleed or cause pain. An AVM in your brain may not cause symptoms unless it bleeds.

Vascular malformations close to the surface of the skin can often be seen during physical examination. Deeper vascular malformations are typically diagnosed using MRI (magnetic resonance imaging). Vascular malformations can cause a variety of symptoms depending on the vessels involved and their location in the body.

Capillary vascular malformations (telangiectatic naevi or nevi) are sometimes incorrectly referred to as flat haemangiomas. These are not haemangiomas but are malformed dilated blood vessels in the skin. Lesions are non-cancerous and appear as blotches of red or purple skin discolouration on any part of the body.

What are venous malformations? Venous malformations are a type of vascular naevus or birthmark. They are due to malformed dilated veins and are non-cancerous. They appear as skin coloured, blue or purple swellings on any part of the body, and there are often prominent veins near the skin surface.

Vascular anomalies -- blood vessels or lymph vessels that haven’t developed correctly -- may be present at birth but can cause concern at any age. Their type, location, and size determines their severity. They can be simple benign growths or, in extreme cases, they can be life-threatening.

There are many types of vascular malformations (listed below) which reflect the types of blood vessels which are involved. They may occur singly or multiply, may involve the skin or internal organs (such as the liver, lungs, or brain), or both.

A vascular malformation can occur in or just under the skin, inside the body near organs, in the mouth, or in the brain. There are 5 types of vascular malformations: Capillary malformation. This is when tiny blood vessels form a red or purple mark on the skin. It’s also called a port wine stain. Venous malformation.

What are Vascular Malformations & Anomalies? Vascular malformations or anomalies are unusual, noncancerous growths of blood vessels. They can be inside the body or on the skin, in the form of birthmarks. Sometimes, they can’t be seen for weeks or months after birth, but they grow slowly throughout a lifetime.

Most birthmarks represent a superficial vascular malformation, consisting of abnormal collections of small blood vessels near the skin. Typically, this CVM type of birthmark does not go away nor does it enlarge, growing only at the same rate as the child.
