摘　　要：目的探讨彩色多普勒超声在原发性深静脉瓣膜功能不全对骨科大手术后深静脉血栓形成影响的应用。方法 106例骨科大手术患者,术前超声检查原发性深静脉瓣膜功能者44例(功能不全组)和瓣膜功能者62例(正常组)。术后超声监测下肢深静脉血栓的发生情况,栓测深静血管管径、管腔压闭情况及血流频谱。计算深静脉血栓的发生率。结果原发性深静脉瓣膜功能不全组深静脉血栓发生率63.60%(28/44),深静脉瓣膜功能正常组深静脉血栓发生率19.35%(12/62),前者高于后者,差异有统计学意义(P<0.05)。结论原发性深静脉瓣膜功能不全是骨科大手术后下肢深静脉血栓发生的危险因素,超声可作为早期诊断和干预治疗的有效方法。Objective To evaluate the association of primary deep venous valvular incompetence of lower limb （PDVI） and the occurrence of deep vein throalbosis（DVT） after major orthopedic operation by color Doppler flow image（CDFI）. Methods One hundred and six patients were examined by CDFI before major orthopedic operation. The patients were divided into two groups according to the presence of backstreaming in femoral vein. After the operation, all the patients were re- examined by CDFI to find if there was DVT. Results The DVT incidence rate in backstreaming veins group was 63.60% （28/44） whereas it was 19.35%（12/62） in normal group. Compared with that in the normal group, there was a higher incidence of DVT in the baekstreaming group（P〈0.05）. Conclusion PDVI may be a risk factor of the occurrence of DVT after major orthopedic operation. CDFI is an effective method for the early diagnosis and intervention.
