【摘要】：目的探讨无症状患者中心静脉置管(central venous catheter,CVC)拔管彩超筛查静脉血栓的临床意义。方法回顾性分析2014年7月至2016年6月我科会诊的无临床症状CVC相关静脉血栓形成患者超声所示血栓情况,处理方式及后续随访结果。结果纳入306例患者,超声提示血栓大小(7.5~22)mm×(2.3~4)mm,平均(4.9±2.31)mm×(13±0.97)mm,所有患者按原计划拔出导管,未发生肺栓塞相关临床症状事件,未单纯因超声提示血栓接受额外抗凝治疗,随访过程中大多数患者未再见血栓。结论通过超声筛查发现的无症状患者中心静脉置管附壁血栓,致症状性肺栓塞风险低危,无需特殊处理,因此拔管前置管处彩超检查临床价值不大。
[Abstract]:Objective to investigate the clinical significance of color Doppler ultrasonography in the screening of venous thrombosis in asymptomatic patients with central venous catheterization catheterization. Methods from July 2014 to June 2016, we retrospectively analyzed the clinical symptoms of venous thrombosis associated with CVC. Of the thrombus as shown by ultrasound, Results in 306 patients, the size of thrombus was 7.52mm 脳 2.3mm 脳 2.3mm, with an average of 4.9 卤2.31)mm 脳 13 卤0.97mm. All the patients pulled out the catheter according to the original plan, and there were no clinical symptoms associated with pulmonary embolism. Most of the patients were not treated with extra anticoagulant therapy because of ultrasound alone. Conclusion the risk of symptomatic pulmonary embolism is low in asymptomatic patients with central venous catheterization and wall thrombosis found by ultrasound screening. There is no need for special treatment, so the clinical value of color Doppler ultrasound examination is not significant.
