Key result
Dynamic 40-slice ECG-gated cine CTA demonstrated a 2.2- to 3.4-mm increase in aortic wall circumference and a 2.4- to 3.6-mm increase in luminal circumference per cardiac cycle in AAA patients.
Why the study?
Does 40-slice ECG-gated cine CTA accurately characterize aortic motion and circumference changes during the cardiac cycle in preoperative AAA patients?
Observational (n=10)
Does 40-slice ECG-gated cine CTA accurately characterize aortic motion and circumference changes during the cardiac cycle in preoperative AAA patients?
Dynamic cine CTA demonstrates significant changes in aortic circumference during the cardiac cycle in AAA patients, which may have important implications for endograft sizing and design.
No takes yet. Share an insight, caveat, or question.
Dynamic aortic expansion in AAA may affect endograft sizing; hypothesis-generating and should not yet change practice.
Teutelink et al. (2006) conducted an observational in abdominal aortic aneurysm (n=10). 40-slice ECG-gated cine computed tomographic angiography (CTA) was evaluated on Changes in aortic circumference for both the aortic wall and the luminal diameter. Dynamic 40-slice ECG-gated cine CTA demonstrated a 2.2- to 3.4-mm increase in aortic wall circumference and a 2.4- to 3.6-mm increase in luminal circumference per cardiac cycle in AAA patients.
