It aims to improve care by helping people who are at risk to get tested, specifying how often to monitor asymptomatic aneurysms, and identifying when aneurysm repair is needed and which procedure will work best. Aortic disease or an injury may also cause an aneurysm. Imaging has a key role in active surveillance. Follow-up of a previously demonst rated AAA This bulge or swelling is called an abdominal aortic aneurysm, or AAA. An aneurysm ("AN-yuh-rizm") is a bulge in a weakened blood vessel. Box 1. The SVS suggests a door-to-intervention time of <90 minutes, based on a framework of 30-30-30 minutes, for the management of the patient with a ruptured aneurysm. The SVS also suggests that elective open aneurysm repair be limited to hospitals with a documented mortality of 5% and that perform 10 open aortic operations of any type each year. Refer people with an AAA that is 5.5 cm or larger to a regional vascular service, to be seen within 2 weeks of diagnosis Refer people with an AAA that is 3.0 cm to 5.4 cm to a regional vascular service, to be seen within 12 weeks of diagnosis Offer an aortic ultrasound to people with a suspected AAA on abdominal palpation Who is it for?

The acronym for an abdominal aortic aneurysm is AAA and is commonly called "a triple A" in health care settings. Your heart pumps blood to the lower part of your body through a large blood vessel called the "abdominal aorta." If an aneurysm develops here, it is called an abdominal aortic aneurysm. Typically, abdominal aortic aneurysms should be treated when their size is greater than 5.4 cm. Thus, for the majority of patients, an infrarenal aorta with a maximum diameter 3.0 cm is considered aneurysmal [ 3-5 ]. Abdominal aortic aneurysms (AAA) are focal dilatations of the abdominal aorta measuring 50% greater than the proximal normal segment, or >3 cm in maximum diameter.
