Key result
Observation of unruptured abdominal aortic aneurysms over a mean of 42 months revealed that growth is predominantly staccato (65%), rather than continuous (23%) or absent (12%).
Cohort (n=52)
Abdominal aortic aneurysm growth is typically discontinuous (staccato), suggesting that past growth rates cannot reliably predict future growth rates for individual patients.

Staccato AAA growth may require flexible surveillance; leaves open optimal imaging intervals in prospective studies.
Kurvers et al. (2004) conducted a cohort in unruptured abdominal aortic aneurysms (n=52). Observation of unruptured abdominal aortic aneurysms was evaluated on AAA growth pattern (staccato, continuous, or no growth). Observation of unruptured abdominal aortic aneurysms over a mean of 42 months revealed that growth is predominantly staccato (65%), rather than continuous (23%) or absent (12%).
