Hi! again,

I would like to summarise my presentation at the
symposium.


Vascular anomalies are nowadays classified into:

1. Hemangiomas
-capillary endothelial tumors

2. Vascular malformation
-abnormally formed vascular structures which can be
capillary,
venous, lymphatic or arteriovenous malformations
(arteriovenous malformations are direct connection
between
arteries & veins without the capillary junction)

Basically, we do not need to treat hemangiomas, they arise
at the time of birth & disappear spontaneously at 4-7
year's of age.

As for the vascular malformations, we usually sclerose
them. However, there are many sclerosants & we do not
fully understand their mechanism of action. We have
investigated 3 main sclerosants that are widely used in
many instituions around the world.

1. absolute ethanol
2. 1% polidocanol
3. OK-432 or picibanil

They have different mechanism of action and are indicated
for different lesions.

We saw a few cases of such lesions at Goroka & PMGH. The
one we saw in Pom, was an adolescent girl, who had a large
venous malformation of the right cheek area which was
excised in Melbourne. However, there was a horrible
deformity of the area. In the future, we could introduce
sclerotherapy for such patients.

Please, ask any questions if you have!
