Aneurysm is the Name for the Expansion of Blood Vessels

Abstract

Aneurysm is the name for the expansion of blood vessels. In order to define an aneurysm, the focal enlargement of the artery must be at least 50% of its normal diameter. Aneurysms occur in places where the blood vessel wall is weakened. As a result of the expansion of the aneurysm, a blood vessel may burst and bleed, which may have a fatal outcome, and the aneurysm may also be the site of thrombosis and the origin of clots. Aneurysm treatment is usually operative.
