Aneurysms Arterial aneurysms are a major cause of death. Early detection allows for definitive repair. Aneurysms caused by degenerative etiologies enlarge over years to
decades. Aneurysms caused by infectious or traumatic
etiologies expand over days to months. Localized arterial permanent dilatation arterial wall weakens
until it bulges outward. (then it can rupture) Underlying cause atherosclerotic changes in a vessel,
trauma, congenital weakness, infection, or inflammation. Clinical manifestations depend on the site. Classified as true or false aneurysms. Frequently found in cerebral circulation and thoracic and
abdominal aorta. (AAA) Dissecting aortic aneurysms are a medical emergency and
treated medically and/or surgically. Classification of Aneurysms
Classification True---all 3 layers of the vessel are involved.
---all Saccular---weakening confined to one
side of the vessel.
Fusiform---weakening of both sides of the
vessel False---at least one layer of the vessels is
unaffected. Dissecting---tear in the vessel wall that
creates a channel of blood flow between the
layers of the vessel.(bleeds in between layers of
