The first step in the treatment of this diverse group of conditions is making the proper diagnosis. Many, if not most of the patients we see in initial consultation have been misdiagnosed in the past. At the AVM Center of New York at Lenox Hill, our goal is to correctly diagnose and treat the unique medical problem that you or your loved one is facing.
This term is commonly (and mistakenly) applied to all congenital vascular lesions, but it actually describes a very distinct condition which is confined to infancy and early childhood. This is the lesion seen in infants and sometimes referred to as a “strawberry birthmark.” It is quite common in the general population, occurring in up to 12% of infants. It is significantly more common in premature infants, females, and in the Caucasian population, and may be present at birth or appear shortly thereafter. It is a single lesion in most infants, but can be multiple on occasion. This is not a malformation but a benign tumor of the endothelial cells (the cells which normally form the walls of blood vessels). What makes these conditions unique is their characteristic progression through three distinct stages: appearance (at birth or shortly after), a “proliferative” stage when the hemangioma can grow quite rapidly (lasting weeks to months) and the “involution” stage (spontaneous fading of the bright red color, shrinkage and resolution), usually by the age of 7 or 8 years.
Diagnostically, most hemangiomas have such a typical appearance and follow such a predictable chronological course that the diagnosis is easily made clinically and no further diagnostic testing is required. On occasion, a hemangioma located more deeply may appear as a soft tissue mass, which may require imaging studies (CT, MRI) or rarely a biopsy to confirm the diagnosis. While CT and MRI scans are ‘non-invasive” tests, they will generally require sedation or anesthesia in infants and children, so that their use is reserved for lesions which are of indeterminate nature clinically or when treatment is required.read more about hemangioma

Vascular malformations are congenital abnormalities in which some part of the vascular system develops abnormally. These tend to be present from birth and in most cases do not run in families, so that they are considered congenital but not genetically transmitted. Usually these are isolated abnormalities in an otherwise normal individual. They may be found incidentally or cause symptoms ranging from mild discomfort to very severe medical complications. There are a large number of classification systems which are too complex for a nonprofessional to deal with, however there are certain specific categories which will be easily understood.
