From: Multidetector computed tomography study to measure thoracic aorta diameters in Egyptian population
Variable (Diameter) | Age groups | 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 aorta at pulmonary bifurcation | Mean of systolic and diastolic diameters | 22.5 ± 2.2 | 24.1 ± 2.8 | 25.1 ± 2.9 | < 0.001 |
Indexed mean systolic and diastolic diameters | 11.3 ± 1.1 | 12.1 ± 1.4 | 13.0 ± 1.4 | < 0.001 | |
