Endovascular aneurysm repair(EVAR)
• Inserting graft components folded and compressed within a delivery sheath through the lumen of an access vessel, usually the common femoral artery
• Upon deployment, the endograft expands, contacting the aortic wall proximally and iliac vessels distally to exclude the aortic aneurysm sac from aortic blood flow and pressure
Abdominal aortic aneurysm(AAA)
• The abdominal aorta is the most common site of arterial aneurysm
• Diameter of the dilated region is increased more than 50 percent relative to normal aortic diameter
• The normal diameter of the aorta at the level of the renal arteries is approximately 2.0 cm (range 1.4 to 3.0 cm).
