目的：探讨高压注射器联合静脉留置针在CT 血管造影评价兔脑血栓模型中的应用价值。方法将行CT血管造影的38例兔脑血栓模型分为实验组和对照组，各19例。实验组采用静脉留置针穿刺兔耳缘静脉置管并连接高压注射器，团注法注射对比剂；对照组采用传统静脉注射法联合高压注射器。对两组 CT 增强扫描图像质量以及穿刺结局进行观察统计。结果实验组19例兔脑血栓模型中图像质量优18例（94．74％），对照组中图像质量优13例（68．42％），二者差异有统计学意义（Z＝－2．099，P＝0．036）。实验组中所有兔模型颈动脉 CT 造影均顺利，图像可显示血栓部位和情况。结论静脉留置针联合高压注射器行血管造影对比剂注射，应用于 CT 增强扫描可提高实验效率，简化操作程序，有效达到评价目的，是 CT 血管造影评价兔脑血栓模型中实用的实验方法。

Objective To explore the application and problems of using high pressure injection combine detaining needle in cere‐bral thrombosis on CT angiography in rabbit models .Methods 38 rabbit models were divided to experimental group and control group (19 cases each) .Rabbits in the experimental group were injected contrast medium into rabbit ear marginal vein with detaining needles and connected high pressure injection and the control group used intravenous infusion combined high pressure injection . Then observe the CT image quality and infusion outcome in two groups .Results There were 18 cases (94 .74% ) in the experimen‐tal group obtained successful infusion and excellent image quality ,and 13 cases (68 .42% ) in the control group got excellent image , the difference has statistical significance (Z = - 2 .099 ,P = 0 .036) .All of the images of experimental group showed thrombosis clearly .Conclusion High pressure injection combine detaining needle on CT angiography can increase test efficiency ,simplify the operation sequence and achieve evaluating goals .
