What is a triple A stent?
The Endurant II AAA Stent Graft System is placed inside the abdominal aorta through catheters inserted into blood vessels in the groin. The device is designed to conform to a broad range of aortic anatomies, empowering physicians to offer endovascular aortic repair (EVAR) to more AAA patients than ever before.
How long does an abdominal aortic stent last?
Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.
How is an aortic stent placed?
During the procedure, a surgeon makes an incision through an artery in your groin. A thin, flexible tube (catheter) is threaded up through the artery and to the site of the aortic aneurysm. A stent graft is sent along the catheter to the aneurysm.
How long does AAA stent surgery take?

They are made to be permanent — once a stent is placed, it’s there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.
How long does a AAA repair last?
The 1-year mortality after open AAA repair was 8 %. Overall, 39 % of patients died within 10 postoperative years (mean 6.0 ± 2.8 years). Long-term survival of patients with a ruptured or symptomatic aneurysm was similar to that of patients undergoing elective aneurysm repair.
How are stents used to treat abdominal aneurysms?
The Alto™ Abdominal Stent Graft System is used to treat patients with aneurysms of the infrarenal abdominal aorta. What will it accomplish? The Alto™ Abdominal Stent Graft System prevents further growth and rupture of the aneurysm.
What are the different types of aortic stents?
A diagram of the aorta. An aortic stent is a tiny tube-like structure that is inserted into the aorta to prop it open. There are a few types of aortic stents that physicians use today. These are often made from metal, and some are covered with fabric. Some aortic stents also release medications to help keep the artery open.
How does the Alto abdominal stent system work?
The Alto™ Abdominal Stent Graft System prevents further growth and rupture of the aneurysm. If the device does not completely seal off the aneurysm from blood flow, additional procedures may be needed to prevent aneurysm growth and rupture.
What are the components of an abdominal stent system?
The system consists of the following components: 1 Implant: Plastic tubes with sealed polymer-filled plastic outer rings with an upper bare metal framework (stent) made of nickel-titanium alloy (nitinol) 2 Extension Implants: Plastic tubes supported by internal stents made of nitinol 3 Delivery Catheter: A long thin tube used to place the implants
