Abdominal endovascular aneurysm repair (EVAR) is a minimally invasive alternative to major open surgery for the repair of abdominal aortic aneurysms (AAAs) that results in reduced recovery times and potentially improved survival rates.
An abdominal aortic aneurysm (AAA) is a localized bulging or abnormal enlargement of the abdominal aorta, most often the infrarenal and aorto-iliac arteries.
Detection can be difficult. Most AAAs are asymptomatic. Frequently, they are discovered on X-rays performed for other reasons.
The mortality rate is high2 due to rupture,3 making timely detection and repair critical.
United States Preventative Services Task Force recommends:
One-time screening for men 65 or older, particularly if the patient is an ever-smoker or has a family history.
Use this 3-minute video to explain AAAs, risk factors, and treatment options.
Two of the most common methods of repairing AAAs are traditional open surgery and endovascular aortic repair (EVAR).
In the surgical procedure, the walls of the aneurysm are replaced with a synthetic graft.
In the EVAR procedure, a stent graft is inserted into the aneurysm through small incisions in the groin.
Minimally invasive endovascular aneurysm repair using the abdominal stent graft.
EVAR of the abdominal aorta is performed using an AAA stent graft. The AAA stent is placed within the aneurysm to provide a permanent, alternative conduit for blood flow within the patient’s vasculature, thereby excluding the aneurysmal sac from blood flow and pressure and preventing the walls of the aneurysm from rupturing.
The AAA stent graft is inserted into the aneurysm through small incisions in the groin and without surgically opening or removing part of the aorta, thereby offering an alternative treatment choice to open surgery.
You can be confident in your outcomes.
Optimize outcomes for the broadest patient base with:
Only the Endurant™ II/IIs stent graft system has the deep clinical experience and favorable clinical outcomes designed to treat both straightforward and challenging anatomy.
