Private,
There is a project for Aneurism (https://www.geni.com/projects/People-Who-Died-as-a-Result-of-an-Ane...)
It is a more general category so that it covers an aneurysm anywhere in the body...
See if it fits. It is under the Cardiovascular heading as it is associated with blood vessels.
This would be a question that would fit in this discussion:
https://www.geni.com/discussions/172707 Cause of Death Projects needed??? (links to pg 1)
*** Use this site if you have a cause of death that you don’t find in the Cause of death portal… this is a site I started to kind of keep them all in one place. I monitor this site freq so would respond quickly if you put a question or need for a new death related project--medically related or other cause.
