What are the chances of a cavernoma bleeding?

The risk of having a haemorrhage varies from person to person, depending on whether you have experienced any bleeding before.

If you haven't had any bleeding before, it's estimated you have a less than 1% chance of experiencinga haemorrhageeach year.

If your cavernoma has bled previously, your risk of having another haemorrhage is somewhere between 4% and 25% each year.

However,this risk decreases progressively over time if you don't experience any further bleeds, and eventually returns to the same level as that of people who haven't had any bleeding before.

Your level of risk will be one of the main factors taken into consideration when deciding if you would benefit from treatment.
