Novel treatment effective for sidewall brain aneurysm

A novel mesh plug that has been traditionally used to treat brain aneurysms occurring where the blood vessels branch out was found to be equally effective in treating aneurysms on the side of the vessel, according to a study ...

Studies compare best ways to treat wide-neck aneurysms

Aneurysms are weak, bulging portions of blood vessel walls. These blood-filled sacs resemble balloons in structure and have necks like balloons. Some aneurysms have larger necks and are called "wide-neck" aneurysms. These ...

Aneurysm

An aneurysm or aneurism (from Ancient Greek: ἀνεύρυσμα - aneurusma "dilation", from ἀνευρύνειν - aneurunein "to dilate") is a localized, blood-filled balloon-like bulge in the wall of a blood vessel. Aneurysms can commonly occur in arteries at the base of the brain (the circle of Willis) and an aortic aneurysm occurs in the main artery carrying blood from the left ventricle of the heart. When the size of an aneurysm increases, there is a significant risk of rupture, resulting in severe hemorrhage, other complications or death. Aneurysms can be hereditary or caused by disease, both of which cause the wall of the blood vessel to weaken.
