Abstract：Objective: To study the hemodynamic differences between distal abdominal aorta and common iliac artery caused by different degrees of ipsilateral common iliac arterial stenosis in swine. Methods: The lateral wall of common iliac artery was pinched with vascular clamp resulting in 1/4, 1/2, 3/4 stenosis in 6 juvenile domestic piglets. The parameters of PSV, MDV were obtained in all objects and analyzed with SPSS 13.0 statistical package. Results: PSV had significant negative correlation with stenotic degree, and MDV increased negatively with aggravated stenosis. The ipsilateral common iliac artery hemodynamics caused by common iliac artery stenosis changed more significant than the distal abdominal aorta. The backward needle ridge emerged in ipsilateral common iliac artery when stenosis reached a certain degree and increased with aggravated stenosis. Conclusions: The different position upstream hemodynamics caused by stenosis is different. The more striking the hemodynamics changes, the nearer to the position of stenosis. The backward needle ridge illustrates its position adjacent to the stenosis.
