1 Rapid dilation of the abdominal aorta during infusion of angiotensin II detected by noninvasive high-frequency ultrasonography  Chiara Barisione, BSc, Richard Charnigo, PhD, Deborah A. Howatt, BSc, Jessica J. Moorleghen, BSc, Debra L.

2 Fig 1 Measurement of murine aortic luminal dimensions in vivo by ultrasonography. Photographs are shown of apolipoprotein E−/− mice infused with either saline (left) or angiotensin II (right) for 28 days. The regions used to acquire images are indicated on these photographs. Samples of short-axis ultrasonic images at these abdominal aortic regions are shown (A and C, suprarenal region; B and D, at the level the left renal branch). The perimeter of the aortic lumen is outlined by yellow dotted lines. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 Comparison of aortic lumen measurements acquired in vivo by ultrasonography and ex vivo by histology. Apolipoprotein E−/− mice infused with either saline or angiotensin II for 28 days were subjected to ultrasonography to determine the maximum lumen diameter in the suprarenal region. At the termination of the study, mice were perfusion-fixed at approximately 100 mm Hg, and their entire suprarenal aortas were sectioned to determine the region of maximal dilation. Points represent the maximal lumen diameter for individual mice for ex vivo and in vivo measurements. The two measurements were highly correlated with each other (r = ).

4 Fig 3 Sequential measurements of abdominal aortic luminal diameters of apolipoprotein E−/− mice during infusion with either saline or angiotensin II (AngII). Mice were infused with saline or AngII for 28 days and monitored at frequent intervals. Data are shown for AngII-infused mice that developed abdominal aortic aneurysms and survived the infusion period. Abdominal aortic luminal diameters were measured in the suprarenal region of mice infused with saline (triangles; n = 8 at all time points) or AngII (circles; n = 12). Data are based on the measurement of diameters at each time point by at least two independent operators. Symbols represent means, and bars represent SEMs. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

5 Fig 4 Lumen diameters of the suprarenal aortas of angiotensin II–infused mice that subsequently died of abdominal aortic rupture. Each curve represents an example of temporal changes in luminal diameters of individual mice. In all of these examples, aortic rupture of the suprarenal region occurred 1 or 2 days after the final luminal measurement.
