彩色多普勒超声诊断下肢深静脉血栓的应用价值研究

Study on the significance of color Doppler ultrasound in diagnosis of deep venous thrombosis

目的探讨彩色多普勒超声诊断下肢深静脉血栓的应用价值。方法 90例下肢深静脉血栓患者均接受彩色多普勒超声检查,采用GE LOGIQ E9彩色多普勒超声诊断仪,依次检查双侧髂总静脉、髂外静脉、股静脉、腘静脉、胫后静脉、胫前静脉及其分支,观察下肢深静脉血栓分布情况及各种血栓声像图特征。结果①90例患者中,共显示103条患肢存在下肢深静脉血栓,其中单侧77例,双侧13例,左侧74条(71.84%),右侧29条(28.16%)。股静脉血栓比率最高,为32.04%;其次为髂静脉及股静脉,为21.36%;髂静脉比率最低,为4.85%。②超声图像显示急性血栓呈均匀低回声,静脉管腔闭塞或部分堵塞,病变处管腔增宽,管壁光滑。超声图像显示慢性血栓呈不规则形强回声,静脉管腔闭塞或部分堵塞,病变处管腔变小,管壁局限性或弥漫性增厚,内壁毛糙。结论彩色多普勒超声在下肢深静脉血栓的诊断中具有很高的应用价值。

Objective To explore the significance of color Doppler ultrasound in diagnosis of deep venous thrombosis. Methods Ninety patients with deep vein thrombosis were examined by color Doppler ultrasound using GE LOGIQ E9 color Doppler ultrasonographic instrument for checking bilateral iliac vein, external iliac vein, femoral vein, popliteal vein, posterior tibia] vein, anterior tibia] vein and its branches, in order to observe the distribution of deep vein thrombosis and various thrombotic uhrasonographic characteristics. Results 1. Deep venous thrombosis had been found in 103 limbs of 90 patients including unilateral venous thrombosis in 77 cases, bilateral thrombosis in 13 cases, venous thrombosis located in left side of 74 （71.84% ） limbs, and in right side of 29 （28.16%） limbs. Femoral vein thrombosis occupied highest proportion, and it reached 32.04%, followed by iliac vein and femoral vein reached 21.36%, the lowest percentage in iliac vein reached 4.85%. 2. The ultra- sound image of acute thrombosis manifested as uniform hypoechoic venous lumen occlusion or partial blockage of lumen with widened smooth wall. The ultrasound image in chronic thrombus manifested as irregular hyperechoic shape in occluded or partial occluded venous lumen, and the lumen became smaller with localized or diffuse thickening and rough inner wall. Conclusion Color Doppler ultrasound has high significance in diagnosis of deep venous thrombosis.
