彩色多普勒超声在下肢静脉血栓诊断中的应用价值

Color Doppler ultrasound in the diagnosis of deep vein thrombosis

目的：探讨彩色多普勒超声对下肢静脉血栓的诊断价值。方法选取我：2011年6月~2013年6月收治的120例临床初步诊断为下肢静脉血栓的患者,采用彩色多普勒进行超声检查,同时行数字减影血管造影（DSA）检查,比较彩超结果与数字减影血管造影结果,对诊断资料与手术病理学资料进行回顾性分析。结果120例下肢静脉血栓患者中,单发于左下肢静脉血栓66例,单发于右下肢静脉血栓30例,双下肢同时患病24例。股总静脉：CDFI检查结果为阳性股总静脉血栓40条,DSA检查结果为44条,CDFI的准确性、灵敏性及特异性分别为80.0%、81.8%及75.0%。股深静脉：CDFI的准确性、灵敏性及特异性分别为71.4%、60.0%及71.4%。股浅静脉：77.8%、81.8%及71.4%。腘静脉：92.3%、92.3%及92.3%。胫前静脉：72.2%、75.0%及80.0%。胫后静脉：81.3%、83.3%及75.0%。不同节段CDFI、DSA检查结果对比,阳性率差异无统计学意义（P〉0.05）。结论在对下肢静脉血栓进行诊断时采用彩色多普勒超声进行诊断与鉴别,具有高准确性、高灵敏性及高特异性的特点。

Objective To probe the diagnostic value of color Doppler ultrasounds In the diagnosis of lower limb venous thrombosis. Methods Selected 120 cases of clinical patients with lower extremity venous thrombosis,in our hospital from June 2011 to June 2013 with color Doppler ultrasound examination, at the same time line digital subtraction an-giography（DSA） inspection, will exceed the results compared with digital subtraction angiography results of diagnostic data with surgery and pathology were retrospectively analyzed. Results All of 120 cases of lower limb venous thrombo-sis patients, single in the left lower limb venous thrombosis 66 cases, single in the right lower limb venous thrombo-sis,30 cases of double lower limbs and 24 cases of illness. A total intravenous of a CDFI stock total vein thrombosis who tested positive for 40, DSA examination results for 44, accuracy, sensitivity and specificity of CDFI was 80.0%,81.8% and 75.0% respectively. A deep vein of a CDFI accuracy, sensitivity and specificity of 71.4%, 60.0% and 71.4%respectively. A superficial vein77.8%,81.8%and 71.4%. Political vein92.3%,92.3% and 92.3%. Pretoria vein 72.2%, 75.0% and 80.0%. Posterior tibia vein 81.3%, 83.3% and 81.3%. Different segments of a CDFI, DSA examination,the results of positive difference had no statistical significant difference（P〉0.05）. Conclusion When the diagnosis of deep vein thrombosis using color Doppler ultrasound for diagnosis and identification with high accuracy,high sensitivity and high specificity characteristics.
