彩色多普勒超声在下肢深静脉血栓诊断中的应用分析

Analysis on Color Doppler Ultrasound Application in Diagnosis of Deep Venous Thrombosis of Lower Extremity

目的：探讨彩色多普勒超声在下肢深静脉血栓诊断中的应用分析。方法选取2013年12月～2014年12月我院接诊的42例下肢深静脉血栓患者，随机分为实验组和对照组，实验组采用彩色多普勒超声诊断技术，对照组采用数字减影血管造影（DSA）诊断技术，观察两组患者的诊断效果。结果实验组患者的诊断准确率、并发症的发生率好于对照组，差异有统计学意义（P〈0.05）。结论彩色多普勒超声在下肢深静脉血栓诊断中的效果显著，诊断率高，并发症的发生率低。

Objective To evaluate the efficacy of color doppler ultrasound application in diagnosis of deep venous thrombosis of lower extremity. Methods We chose 42 patients suffering from deep venous thrombosis of lower extremity who were treated in hospital from December 2013 to December 2014 and separated them into study group and control group at random. Patients in study group were given color doppler ultrasound examination; while patients in control group were diagnosed by DSA（digital subtraction angiography）,and then compared diagnosis effect of two groups. Results Diagnosis accuracy and complication incidence in study group were much better than those in control group; there was a diagnosis differential between two groups,and such a differential had statistic value（P〈0.05）. Conclusion Color doppler ultrasound examination is accurate and efficiency in diagnosis of deep venous thrombosis of lower extremity; it is conducive to increasing diagnosis efficiency and reducing complication incidence,therefore,color doppler ultrasound examination is rather worthwhile to be promoted and applied in diagnosis of deep venous thrombosis.
