Dilatation and expansion of the arterial wall

Narrowing of the arterial wall

Complete blockage of the artery

Formation of new arteries

Rupture, thrombosis, embolization, high risk in males over 60

Hypertension, diabetes, stroke, high risk in children

Atherosclerosis, infection, low blood pressure, high risk in females

Arrhythmia, heart failure, high cholesterol, high risk in young adults

larger sizes correlate with increased wall stress and higher likelihood of rupture.

Fusiform aneurysms involve diffuse enlargement and are most common

Saccular aneurysms have a focal bulge with a sac-like appearance

Saccular aneurysms become dangerous at a smaller size than fusiform

Fusiform aneurysms originate from one side of the aorta

occurs when blood flows through the graft material.

endograft fabric rupture

a leak from the main body of the endograft.
