Current research says that for patients with abdominal aortic aneurysm of 4.0-5.5 cm in size (which is considered a small
size) either surgical repair or frequent ultrasound of their aorta is acceptable. Patient should be the one to make this choice. However,
if AAA starts to expand >1 cm/year or causes patient to have symptoms, surgical repair should be considered.
