目的探讨下肢深静脉血栓采用彩色多普勒超声检查的诊断价值。方法选择该院2015年10月—2016年10月收治的85例下肢深静脉血栓患者,全部患者均采用数彩色多普勒超声(CDUS)进行检查,记录检查的诊断结果,并和数字减影血管造影(DSA)的检查结果对比。结果血栓发生部位:右下肢21例,左下肢48例,双下肢16例;发病类型:25例急性血栓,40例亚急性血栓,20例慢性血栓;发病血管分类:37例中央型血栓,27例周围型血栓,21例混合型血栓;栓塞程度:完全栓塞型36例,不完全栓塞型49例;CDUS与DSA的检查结果相吻合,诊断符合率是95.29%(81/85)。结论应用彩色多普勒超声诊断下肢深静脉血栓具有操作简单,无创伤性,可重复性,灵敏性和高特异性等优点,值得临床推广使用。
Objective To investigate the diagnostic value of color Doppler ultrasonography in the diagnosis of deep venous thrombosis of lower limbs. Methods Eighty-five patients with deep venous thrombosis of lower extremities admitted from October 2015 to October 2016 in our hospital were enrolled. All patients were examined by digital color Doppler ultrasonography (CDUS). The diagnostic results were recorded and compared with digital subtraction Comparison of angiography (DSA) examination results. Results Thrombus occurred in 21 cases of right lower limb, 48 cases of left lower limb and 16 cases of double lower extremity. The incidence types were 25 cases of acute thrombus, 40 cases of subacute thrombus and 20 cases of chronic thrombus. The incidence of vascular classification was 37 cases of central thrombus 27 Thromboembolism occurred in 21 cases with mixed thrombus. The embolization degree was 36 cases of complete embolization and 49 cases of incomplete embolization. The coincidence of CDUS and DSA was 95.29% (81/85). Conclusion The application of color Doppler ultrasonography in the diagnosis of deep venous thrombosis of lower extremity has the advantages of simple operation, non-invasiveness, repeatability, sensitivity and high specificity, which is worthy of clinical promotion.
