abdominal aortic aneurysm

Background

Abdominal aortic aneurysms (AAA) occur in the part of the aorta that passes through the abdomen (abdominal aorta). The abdominal aorta represents the location of 80% of all aortic aneurysms.


Approximately 4.5 million people in the developed world are living with an AAA. As many as 8% of people over the age of 65 have an AAA*.


While smaller aneurysms rarely rupture, those that get wider (5 centimeters and over) often require surgery due to the increased chance of rupture. Aortic aneurysms are most often treated with a conventional endovascular aneurysm repair (EVAR) using commercially available stent-grafts, versus open surgical repair, an invasive, complicated, and lengthy (4 to 6 hour) procedure. Approximately 50% of patients who do not undergo treatment die of ruptured AAAs*. Ruptured AAAs represent the tenth leading cause of death in men over 55, accounting for more than 15,000 deaths in the United States each year. However, approximately 40% of patients are not suitable candidates for EVAR due to inadequate aortic neck anatomy (<12 mm)*.


Currently, there are very limited, expensive procedures for those prevented from undergoing EVAR. Many patients who do not qualify for EVAR will benefit from BiFlow Medical’s side-branch stent and will then be candidates for EVAR.

Technical improvements in graft design and advances in delivery techniques will result in the increased application of EVAR.
