ABSTRACT
|
|
Aims:
The diameter of ascending aorta changes in different stages of cardiac cycle in normal, dissected and aneurysmal aorta. The differences in size of arch of aorta during cardiac cycle in atherosclerotic patients are not well established. Here we studied the long and short axis diameter of arch of aorta in atherosclerotic patients to assess the differences in diameter in different stages of cardiac cycle.
Methods: This study involved evaluation of retrospective data, for patients who underwent retrospectively gated cardiac computed tomogrphy (CT) scan examinations for various indications. Zones 0–4 were identified from CT scan as per Shin Ishimaru’s division of arch of aorta. The short axis and long axis, along with the average of the two, were obtained both in systole and diastole, at the same level. The measurements were taken from outer wall to outer wall of the aorta. Results: Data from 27 patients (11 females and 16 males) was reviewed. The age range was 50–89 years. A total of 135 zones were identified and axial diameters (short and long axes) were measured. The average zone variation between the long axis and short axis diameter during systole and diastole did not exceed 1 mm (max = 2.9 mm, min = 0.0 mm) for any zone. The largest difference in average variation was noted in zone 4; 0.58 mm, although this was not statistically significant. Conclusion: Our study suggested that the variation of atherosclerotic aorta is minimal in different phases of cardiac cycle. This should be considered for endovascular intervention in atherosclerotic arch of aorta. | |
