Table 13 Comparison of descending thoracic aortic diameters at the diaphragmatic level among different age groups:
From: Multidetector computed tomography study to measure thoracic aorta diameters in Egyptian population
Variable (diameter) | Age group | P value | |||
|---|---|---|---|---|---|
Group A (< 40 y) (n = 69) | Group B (40–60 y) (n = 312) | Group C (> 60 y) (n = 135) | |||
Mean ± SD (mm) | |||||
Descending thoracic aorta at diaphragm | Mean of systolic and diastolic diameters | 19.6 ± 1.8 | 21.8 ± 2.4 | 23.3 ± 2.8 | < 0.001 |
Indexed mean systolic and diastolic diameters | 9.8 ± 1.0 | 10.9 ± 1.2 | 12.0 ± 1.3 | < 0.001 | |
