'''Repeat''' ultrasounds should be carried out in those who have an aortic size greater than 3.0 cm.<ref name=Brown2013/> Local guidelines apply, but a general recommendation is that in those whose aorta is between 3.0 and 3.9 cm it should be every three years, if between 4.0 and 4.4 cm every two years, and if between 4.5 and 5.4 cm every year.<ref name=Brown2013>{{cite journal |vauthors=Bown MJ, Sweeting MJ, Brown LC, Powell JT, Thompson SG | title = Surveillance intervals for small abdominal aortic aneurysms: a meta-analysis | journal = JAMA | volume = 309 | issue = 8 | pages = 806–13 | date = February 2013 | pmid = 23443444 | doi = 10.1001/jama.2013.950 | url = }}</ref>
