Abstract: Objective:To analyze correlation factors of hemodynamic damage after carotid artery stenting.Methods:In this study, 66 cases (71 lesions) who undertook carotid artery stenting were col-lected and the correlation factors of hemodynamic damage were analyzed .Results:Hemodynamic damage emerged in 23 cases (32.4%), of which, 11.3%developed hypotension.The distance between bifurca-tion and lesions (P=0.002 0), plaque distribution (P=0.000 2), plaque character (P=0.001 9), post-dilation ( P =0.002 6 ) were associated with hemodynamic damage by single factor analysis . However, only eccentric plaque (P=0.015 3) and calcified plaque (P=0.009 7) were associated with hemodynamic damage by multiple factors analysis .All the patients could reach stable circulation by drugs during operation , and no cerebral ischemic events ( transient ischemic attack or stroke ) and cardiovascu-lar ischemic events happened .Conclusion: The distance between bifurcation and lesions , eccentric plaques, calcified plaques are correlation factors of hemodynamic damage .
