【摘要】 目的　探讨高频超声及彩色多谱勒血流显像 (colordopplerflowimaging ,CDFI)对下肢深静脉血栓的诊断价值。方法　对 3 2条经X线血管造影确诊为深静脉血栓的下肢深静脉进行超声观测 ,同时选择正常人 3 6条下肢深静脉进行对比。结果　正常静脉图像清晰 ,回流通畅 ,不同形态不同类型的血栓对血管的阻塞及血栓急、慢性表现有不同的超声特点。结论　与有创的血管造影相比 ,超声具有无创、实时、安全可靠的特点 ,是诊断下肢深静脉血栓病变理想的方法更多还原

【Abstract】 Objective To explore the value of high frequency and color doppler ultrasonography on diagnosis of deep venous thrombus in lower extremitiy.Method 32 cases with lower extremitiy deep venous thrombi diagnosed by angiography were further examined by CDFI,36 healthy cases were randomly selected as the normal group (NOR).Results High frequency and CDFI displayed the venous image in normal lower limbs rapidly and clearly as well as the echographic features of different shapes and types of the obstructed vessels.Conclusion High frequency and CDFI as a non-invasive and realtime method is better than angiography in diagnosis of the disease.更多还原
