摘要
Abstract
Objective To find out the characteristics of anteroposterior abdominal aortic wall motion and to consider the potential implications of such variations. Methods M-mode ultrasound was used to measure abdominal aortic wall motion in human (n=20) and 2 animal species [dogs (n=8), and pigs (n=5)]. Anterior wall displacement (da),posterior wall displacement (dp), and diastolic diameter (Da) were measured. The ratio of displacement to the diameter was calculated (da/Dd. and dp/Dd). Results Aortic diameter varied from to (6.34±0.84) mm (dog) to (13.76±1.11) mm (human).Anterior wall displacement was about 3 times greater than the posterior among the species studied. The ratio of wall displacement to diastolic diameter were similar for the anterior and posterior walls. Wall displacement increased linearly with the diameter. Conclusions Abdominal aortic wall dynamics are similar in humans and animals regardless of the aortic size, with more anterior than posterior wall motion. These data suggest increased .dynamic strain of the anterior wall,which may help explain why human abdominal aortic aneurysms initially develop anteriorly. Haemodynamies plays an important role in the abdominal aortic aneurysm pathogenesis.关键词
