Research Abstract	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.
