Abstract:
Objective To evaluate the efficacy and safety of a domestic arterial thrombus aspiration catheter in treating acute arterial ischemic events in the experimental dogs,and to compare this catheter with Penumbra suction catheter.Methods Acute ischemic embolism model was established in the external carotid and renal arteries of experimental dogs,and the experimental dogs were randomly assigned to the study group and control group.The embolized blood vessels were treated with thrombectomy.Results A total of 12 experimental dogs were enrolled in this study,with 6 dogs in each group.All of the 12 experimental dogs were successfully modeled.In the study group and the control group,the cumulative success rates of thrombectomy were 92.9％and 66.7％respectively(P＞0.05),the incidences of intraoperative vascular dissection were 0％and 8.3％respectively(P＞0.05),and the incidences of vasospasm were 35.7％and 0.75％respectively(P＞0.05).Conclusion In treating thrombus-embolized blood vessels with mechanical thrombectomy in experimental dogs,no statistically significant differences in the efficacy and safety exist between using domestic arterial thrombus aspiration catheter and using Penumbra suction catheter.(J Intervent Radiol,2023,32:1207-1210)
