下肢静脉血栓的彩色多普勒超声诊断

目的 探讨下肢静脉血栓的彩色多普勒超声声像图特点。方法 回顾性分析71例下肢静脉血栓形成患者的彩色多普勒声像图特点。结果 左下肢的发病率明显高于右下肢，常累及股静脉、股浅静脉、股深静脉、月国静脉等。声像图特点为管腔内探及实性高或低回声团块CDFI血流信号变细或无血流信号；脉冲多普勒血流速度减慢且不受呼吸影响。结论 彩色多普勒超声诊断下肢静脉血栓具有直观性、可靠性。

Value of Color Doppler Flow Imaging in Venous Thrombosis of the Lower Limbs

Objective To study the features of Color Doppler Flow Imaging(CDFI) of patients with venous thrombosis of the lower limbs.Methods Review the findings of CDFI of 71 cases with venous thrombosis of the lower limbs retrospectively.Results The most common site of venous thrombosis was the left lower limbs.The femoral vein,superficial femoral vein,deep femoral vein,popliteal vein were involved frequently. Hyper-echo or hypo-echo masses were seen in the lumen.Thin blood flow or no blood flow was observed in Color Doppler.Slow velocity was detected or the velocity was not changed with deep breath in Pulse Doppler.Conclusions CDFI is sensitive and reliable for diagnosing venous thrombosis of the lower limbs.
