目的探讨彩色多普勒血流成像在下肢深静脉血栓(DVT)形成中的应用价值。方法应用彩色多普勒血流显像仪,诊断16例下肢深静脉血栓,描述其声像图特征。结果16条下肢深静脉血栓形成的患者,栓塞部位在髂股、股静脉10例,其中3例合并大隐静脉起始部血栓,腘静脉6例。结论彩色多普勒超声作为诊断下肢深静脉血栓形成具有较强的敏感性和特异性,值得临床推广应用。
Objective To explore the value of color Doppler flow imaging in the formation of deep vein thrombosis (DVT). Methods Color Doppler flow imaging was used to diagnose 16 cases of lower extremity deep venous thrombosis and describe its sonographic features. Results Sixteen patients with deep venous thrombosis of the lower extremities had embolization sites in 10 cases of iliac and femoral veins, of which 3 cases had thrombi in the initial part of saphenous vein and 6 cases of veins. Conclusion Color Doppler ultrasonography as a diagnosis of deep venous thrombosis of lower extremity has strong sensitivity and specificity, worthy of clinical application.
