An aneurysm is a balloon-like bulge in an artery. Typically, arterial walls are thick and strong, but someone with thinner arterial walls is more prone to getting aneurysms because the blood flow pressure is too great. Aneurysm’s are more common in women, and can be caused by a blow to the head, infection, high blood pressure, cigarette smoking, hypertension, drug use, or it can also be hereditary.
Doctors can often successfully treat aneurysms with medication to help lower blood pressure, relax blood vessels, and reduce the risk of rupture. Surgery can also help, in which case doctors will reinforce the vessel walls or replace them if necessary.
