Open surgery typically involves exposure of the dilated portion of the aorta and insertion of a synthetic (Dacron or Gore-Tex) graft (tube). Once the graft is sewn into the proximal (toward the patient's head - and more specifically, towards their aortic valve) and distal (toward the patient's foot) portions of the aorta, the aneurysmal sac is ...
EVAR involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA, [1] and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States. [2]
The prevalence of AAA worldwide in 2019 was about 0.9% in people under age 79 years, [4] whereas a 2014 review reported a range of 2-12%, occurring in about 8% of men more than 65 years of age. [13] Men are about four times more likely to have AA compared to women at any age, with death occurring in about 55-64% of people having AAA rupture.
Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. [1] An AAA usually causes no symptoms, except during rupture. [1] Occasionally, abdominal, back, or leg pain may occur. [2] Large aneurysms can sometimes be felt by pushing on the ...
Graft infection from a Bentall procedure presents similarly to many infections after a major cardiac surgery, with indications in various degrees of severity. Symptoms can include fever, chills, loss of appetite, weight loss, malaise with clinical indications including septic emboli, abscess, left ventricular fistulae, transient ischemic attack.
Open aortic surgery with replacement of the damaged section of the aorta with a tube graft (often made of Dacron) when no damage to the aortic valve is seen; Bentall procedure – replacement of the damaged section of the aorta and replacement of the aortic valve

Common features of both techniques of the replacement process are the clamping of the aorta and the use of a length of Dacron tube (also known as an "aortic graft"), typically 5 cm, to constrict the aortic root to the normal diameter, while the patient is cooled to 20°C and placed on life support. The procedure typically takes 4 to 6 hours in ...
