They’re due to developmental abnormalities
in the blood vessels.
There are a number of different forms, some
of which are very benign such as the hemangioma
of the skin, which usually just disappears
as the child grows. And some can be extremely
clinically dangerous if they’re in the brain
and they bleed and cause strokes and so forth.
And we’ve talked about the hemangiomas,

and the cavernomas which, when they appear
in the brain, can be a real problem. They

We talked about coarctation of the aorta and
also various abnormalities of aortic-arch
development, which also may require surgery
because they obstruct the oesophagus or the
And finally we talked about the cosmetic problem
