| 中文摘要:目的 通过对比溶栓前后自体动静脉内瘘血管通路的通畅情况和血流参数的变化，探讨高频彩超在自体动静脉内瘘溶栓中的监测价值。方法 回顾性分析经临床证实的48例自体动静脉内瘘血栓形成患者的超声图像，对比分析溶栓前后内瘘吻合口血管内径（D），收缩期峰值流速（PSV）、舒张期流速（EDV）、阻力指数（RI）及内瘘血流量（BFV）。结果 溶栓成功41例，有效率85.4%，管腔内实质回声消失，血流信号充满整个管腔，7例溶栓未通，无效率4.6%；溶栓前后瘘口内径比较差异无统计学意义（P >0.05），溶栓前后瘘口血流参数（PSV，EDV，RI）和内瘘血流量的比较，差异有统计学意义（P<0.05）。结论 超声引导自体动静脉内瘘溶栓有较高的有效率，溶栓成功后内瘘血流量明显增加，吻合口血流速度增快，阻力指数明显降低，高频彩超可为临床医生提供准确的量化影像学信息，为其溶栓效果的评价提供支持。 |

| Abstract:Objective To discuss the monitoring value of high-frequency color Doppler ultrasonography in thrombolytic therapy of autogenous arteriovenous fistula, by comparing the flow condition and the change of the blood flow parameters between before and after thrombolytic therapy in autogenous arteriovenous fistula. Methods The ultrasound image manifestation of 48 patients with autogenous arteriovenous fistula proved clinically was retrospectively analyzed.We made a comparison of the diameter (D), the peak systolic velocity (PSV), end-diastolic velocity (EDV), resistance index (RI) and blood flow volume(BFV) of the internal fistula anastomotic orifice blood vessel, before and after thrombolytic therapy. Results In total 41 patients had successful thrombolytic therapy, thrombus echo in blood vessel were disappeared, and blood flow signal was full of blood vessel. The effective rate was 85.4%. However, 7 patients did not be cured, ineffective rate was 4.6%. The blood vessel diameter had no statistic significant between before and after treatment(P >0.05).The blood flow parameters(PSV,EDV,RI) had statistic significant between before and after treatment(P<0.05). Conclusion Thrombolytic therapy of autogenous arteriovenous fistula guided by ultrasound could be more efficiently. Internal fistula blood flow increases significantly after a successful thrombolytic therapy. Blood flow volume of the anastomotic becomes faster, and resistance index is decreased obviously. High-frequency color Doppler ultrasonography can provide accurate quantitative imaging information for clinical doctors so as to evaluate the thrombolysis effect. |
