【摘要】 目的探讨连续2点超声联合D-二聚体(D dimmer,DD)检测在下肢骨折患者术后可疑血栓的应用价值。方法选取下肢骨折术后怀疑下肢深静脉血栓形成的806例患者,随机分为连续2点超声组(A组)及常规下肢静脉彩色多普勒组(B组),A组401例,采用连续2点超声联合DD检测,B组405例,采用常规下肢静脉彩色多普勒检测,无下肢深静脉血栓形成的患者随诊1个月,收集数据并统计分析。结果 806例随访1个月以后,排除遗失病例,A组下肢静脉血栓发生6例(1.6%),B组发生(1.8%)。两组方诊断率相比较,差别无统计学意义(χ~2=0.061,P>0.05)。结论连续2点超声联合D-二聚体检测和常规下肢静脉彩色多普勒对下肢深静脉血栓的检出率相同,但前者较之常规下肢静脉彩色多普勒更简便、快捷、有效,在诊断下肢深静脉血栓形成中有较高的应用价值。更多还原

【Abstract】 Objective To explore the application values of suspected thrombosis under serial 2-point ultrasound plus D-dimer for the lower limb fracture patients after operation.Methods 806 cases after lower limb fracture surgery who were suspected deep venous thrombosis of lower limb were randomly divided into serial 2-point ultrasound group( Group A) and lower limb vein color Doppler group( Group B).The Group A with 401 cases was used serial 2-point ultrasound plus D-dimer.The Group B with 405 cases was used lower limb vein color Doppler.The patients with deep venous thrombosis of the lower limbs were follow- up for 1 month,and the data were collected and analyzed statistically.Results 806 cases were follow-up for 1 month,excluding the missing cases,the venous thrombosis of lower limb in the Group A occurred in 6 of384 cases( 1.6%),the Group B was 1.8%.The difference in the two groups was not statistically significant( χ~2= 0.061,P > 0.05).Conclusion The serial 2- point ultrasound plus D- dimer and lower limb vein color Doppler for deep venous thrombosis of lower limb had the same detection rate,but the serial 2-point ultrasound plus D-dimer was more convenient,fast and effective than the latter.It has a high value in the diagnosis of deep venous thrombosis of lower limb.更多还原
