Vascular malformations arise due to disorders in vascular morphogenesis. This term refers to the ordered differentiation of cells and tissues into the organs and structures of the body.
The first trimester is critical the proper formation of all organs, including the vascular system. Vascular malformations may be seen as birth marks or may be occult at birth and manifest later in life.
They are classified based upon their flow characteristics and on the anatomical structures that are involved. Many vascular malformations show mixed features. They may contain arteries, veins or lymphatics or a combination of these structures.
