Plural of aneurism, meaning multiple instances or locations of dangerous bulges in artery walls where the arterial tissue has weakened.
Simply the plural form of aneurism, formed by adding the standard -s ending to the singular noun.
Some people are at higher risk for multiple aneurisms, especially those with certain genetic conditions—having one aneurism means doctors need to carefully check the rest of your arteries since weakness in one spot might indicate systemic arterial fragility.
