ARIZONA HEART INSTITUTE USING NEW FDA-APPROVED MEDICAL DEVICES TO TREAT ABDOMINAL AORTIC ANEURYSMS
Procedure repairs body’s main artery with minimal surgical treatment, less recovery time
PHOENIX (Jan. 24, 2011) – Abdominal aortic aneurysm (AAA) affects an estimated 1.2 million people in the United States. For many, AAA – or ballooning in the body’s main artery – typically causes no symptoms until it ruptures, which can be deadly. But for those with a known AAA of a certain size, patients may benefit from a minimally invasive treatment alternative to open surgery, including two new medical devices recently approved by the FDA. Dr. Venkatesh Ramaiah, a vascular surgeon at Arizona Heart Institute and Arizona Heart Hospital, is among the first physicians in the nation to use these innovative devices, which are called stent grafts.
A stent graft consists of a flexible wire frame (stent) sewn onto a specially woven fabric tube. Using tiny tubes inserted into blood vessels in the patient’s groin, they’re implanted inside the aorta to create a new path for blood flow, reducing pressure on the aneurysm and the risk of rupture.
Among these devices is the Medtronic Endurant® AAA Stent Graft System, which expands the number of AAA patients who can receive minimally invasive treatment because of its innovative design. “In addition to being easy to navigate through even tight and tortuous arteries, this unique device is designed to conform to a broader range of aortic anatomies, enabling us to offer less invasive options to more complex AAA patients than ever before,” said Dr. Ramaiah. “It requires a landing zone of only 10 mm of healthy tissue between the top of the aneurysm and the lowest renal artery.”
Another novel stent graft that recently gained FDA approval is the GORE® EXCLUDER® AAA Endoprosthesis and GORE® C3 Delivery System which allows surgeons to recapture and reposition the graft during the procedure until they are confident that the device is accurately placed and the aneurysm is completely covered. “This is an extremely important feature when treating patients with certain types of AAAs,” said Dr. Ramaiah. “AAAs tend to occur at or near the critical arteries which branch off of the aorta and supply blood to the kidneys. When placing stent grafts across AAAs, we have to be very careful not to block blood flow through these side branch arteries,” continued Ramaiah.
Minimally invasive stent grafts offer a lower-risk alternative to open surgical repair and are associated with minimal blood loss, faster recovery, and shorter hospital stays.
“We are thrilled to have gained FDA approval on these latest devices to treat abdominal aortic aneurysms,” said Dr. Ramaiah. “Through the research done in our clinical trials, we have seen first hand how innovative technology contributes significantly to lower complications and faster return to normal activities. Our team looks forward to continued research and scientific endeavors that ultimately save lives,” continued Ramaiah.
