Wave intensity change not arterial wall character, but the pressure of the arterial wall. The purpose of this present study is to clarify the change of the wave intensity between pre-, post-stentgraft deployments. The wave intensity of the circulation mock, pig, and clinical cases was measured by an ultrasound device(prosoundα7, ALOKA, Tokyo). In every three group, wave I and II did not change significantly. At pre-and post stentgraft deployment, the pole of refractory wave change in many cases of all groups. The refractory wave change by endoleak was found at the circulation mock. In this present study, the possibility of wave intensity was clarified for the aneurysm diagnosis, including the post-repair endoleak. More suitable device will be expected to measure the wave intensity.

波强度改变的不是动脉壁的性质，而是动脉壁的压力。本研究旨在阐明覆膜支架展开前后波强度的变化。通过超声设备（prosoundα7，ALOKA，Tokyo）测量循环模拟、猪和临床病例的波强度。各组I、II波变化不明显。在支架植入物展开前后，所有组中许多病例的不应波极点发生变化。内漏引起的不应波改变见于循环模拟。在本研究中，阐明了波强度用于动脉瘤诊断的可能性，包括修复后内漏。期望有更合适的装置来测量波的强度。
