Segments of 45 human thoracic and 20 abdominal aortas, including 13 pairs, aged 30-88 yr at autopsy, were perfused with 37 degrees C Tyrode's solution at in-situ length. Diameter changes due to 20 mmHg pressure steps, between 20 and 180 mmHg, were measured to 1 micron accuracy with balanced transducers. Absolute diameter at 100 mmHg was measured to 50 micron accuracy. At 100 mmHg, cross-sectional area ranged from 2.6 to 7.6 for thoracic and from 1.0 to 3.2 cm2 for abdominal segments… CONTINUE READING
