Key result
Computed tomography evaluation of abdominal aortic aneurysms showed synchronous thrombus increase in 5-7 cm aneurysms, while those >7 cm expanded the patent lumen without thrombus increase.
Why the study?
Can computed tomography descriptors of abdominal aortic aneurysms interpret aneurysm stability and potential for rupture?

Can computed tomography descriptors of abdominal aortic aneurysms interpret aneurysm stability and potential for rupture?
CT descriptors, specifically the thrombus-lumen ratio, can effectively describe the changing internal architecture of abdominal aortic aneurysms to interpret stability and potential for rupture.
May refine CT assessment of AAA stability by size; hypothesis-generating for rupture prediction in observational data.
A group of computed tomography (CT) descriptors were derived for abdominal aortic aneurysms. Terminology was defined and applied to the interpretation of the CT image in 55 prospective cases. Correlation of geometric parameters of aneurysm and analysis of the relationship of internal aneurysm components such as lumen and thrombus was performed. Predictive growth patterns for aneurysm demonstrated a synchronous increase in the volume of thrombus within the aneurysm in those aneurysms measuring 5 to 7 cm. Aneurysms greater than 7 cm were associated with an expansion of the patent pulsatile lumen, with no appreciable increase in thrombus volume. The thrombus-lumen ratio effectively described the changing internal architecture of aneurysm associated with increase in size. Proper utilization of CT descriptors develops a language that interprets aneurysm stability and potential for rupture and may provide an improved basis for timely surgical planning.

George Pillari (1988) conducted an observational in Abdominal aortic aneurysm (n=55). Computed tomography (CT) was evaluated on Correlation of geometric parameters and relationship of internal aneurysm components (lumen and thrombus). Computed tomography evaluation of abdominal aortic aneurysms showed synchronous thrombus increase in 5-7 cm aneurysms, while those >7 cm expanded the patent lumen without thrombus increase.
