Can more than one aneurysm occur at the same time?

Yes, it is possible for a person to have multiple aneurysms at the same time. In fact, some people are born with a condition called familial aneurysmal disease, which means that they are more likely to develop multiple aneurysms throughout their lifetime. Additionally, people who have one aneurysm are more likely to develop another aneurysm in the future. This is because the risk factors for aneurysms, such as smoking, high blood pressure, and diabetes, can also contribute to the formation of new aneurysms.
