Vascular malformations are a result of the abnormal growth and development of a single type of vessel or a combination of vessels. Over the years, malformations can grow larger and become problematic depending on what type(s) of vessel is involved.

Can venous malformation spread?

These structural abnormalities can change the blood flow in the affected veins, usually slowing it down, which can sometimes lead to formation of small clots. These are trapped within the malformation so they cannot spread around the body but they can be painful when they form.

Can hemangiomas develop later in life?

Hemangiomas in muscle tissue can develop at any age, but most often occur in young adults. Capillary hemangiomas are more common in muscle than cavernous and compound types.
