ABSTRACT

Lymphatic malformations (LMs) constitute one subset of a

larger group of so-called vascular malformations which may

affect any segment of the vascular tree including arterial,

venous, capillary, and lymphatic vessels. All vascular

malformations can be considered to be the result of errors

of embryonic development and can be categorized accord-

ing to the particular vascular component involved, as well

as by physiologic flow properties. Thus, there exist slow-

flow lesions (which include lymphatic, venous, and capil-

lary malformations), fast-flow anomalies (which contain an

arterial component) and complex, combined vascular

malformations.
