Vascular Malformations and Hemangiomas

Vascular malformations refer to abnormal clusters of blood vessels that occur during early stage development and are present at birth.

 

Although present at birth, some vascular malformations might not appear until a later age; though they will grow in proportion to the development of the child.

 

Some vascular malformations are genetic by nature; others we know form during the development of arteries, veins and vessels. Left alone, a vascular malformation will not subside.

 

A hemangioma is another term used for vascular malformations that occur between birth and 3 months of age and have a rapid rate of growth.
