Congenital diseases of vasculature
Congenital vascular anomalies are rare. Congenital vascular anomalies occur in barely 1% of all births. These are the vascular malformations or vascular tumors i.e., abnormally formed blood vessels present by birth. Congenital vascular diseases include vascular malformations and vascular tumor known as hemangioma; both of which are commonly called “birthmarks”. Most of these birth marks represent vascular malformation, consisting of abnormal collection of small blood vessels near the skin. Normally vascular malformations are not a health threat as they grow proportionately with the growth of the child. But hemangioma may be alarming during their growth phase called the ‘juvenile hemangiomas’ and requires immediate treatment.
