高频超声在诊断术后静脉血栓中的应用价值

Value of High Frequency Ultrasound in Diagnosis of Postoperative Venous Thrombosis

目的:探讨高频超声在术后四肢静脉血栓诊断中的临床应用价值。方法:选取郑州大学第三附属医院2016年1月至2017年7月收治的112例确诊为四肢静脉血栓的患者,进行回顾性分析,总结分析高频超声图像特征及其临床意义。结果:高频超声检查发现,112例患者中有16例(14.3%)上肢静脉血栓,96例(85.7%)下肢静脉血栓;左侧60例(53.6%)、右侧34例(30.3%)、双侧18例(16.1%);低回声58例(51.8%)、等回声26例(23.2%)、高回声22例(19.6%)、混合性回声6例(5.4%)。血栓处内径明显较健侧增宽。结论:高频超声可用于术后四肢静脉血栓的检查,具有重要的临床意义。

Objective To investigate the clinical value of high frequency ultrasound in postoperative venous thrombosis. Methods 112 patients with confirmed venous thrombosis were enrolled. A retrospective analysis was made to summarize and analyze the characteristics and clinical signifi cance of high frequency ultrasound images. Results In 112 cases,16 cases（14.3 %） is the upper extremity venous thrombosis,96 cases（85.7 %） is the venous thrombosis of lower extremity. The left side was in 60 cases（53.6 %）, on the right side in 34 cases（30.3 %）, on both sides in 18 cases（16.1 %）. Hypoechoic thrombus was present in 58 cases（51.8 %）, echo thrombus was in 26 cases（23.2 %）, hyperechoic thrombus was in 22 cases（19.6 %）, mixed echo thrombus was in6 cases（5.4 %）. Thrombus diameter was signifi cantly wider than the healthy side. Conclusions High frequency ultrasound can be used for the diagnosis of postoperative venous thrombosis, and has important clinical signifi cance.
