一种国产新型动脉抽吸导管疗效研究

The efficacy of a new domestic arterial suction catheter in thrombectomy:an experimental study

目的评价一种国产动脉血栓抽吸导管治疗试验犬急性动脉缺血事件的有效性和安全性,并与Penumbra抽吸导管进行比较。方法 在试验犬颈外动脉、肾动脉建立急性缺血栓塞模型,随机分为试验组、对照组,对栓塞血管进行取栓治疗。结果 共纳入试验犬12只,试验组、对照组各6只,均成功建模。试验组、对照组累计取栓成功率分别为92.9%、66.7%(P>0.05),术中血管出现夹层分别为0、8.3%(P>0.05),痉挛率分别为35.7%、75.0%(P>0.05)。结论 试验组与对照组相比,治疗有效性和安全性无显著差异。

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.
