目的:探讨彩色多普勒超声检查对下肢深静脉血栓形成(DVT)的临床诊断及治疗效果观察中的应用价值。方法:应用彩色超声仪对77例DVT患者进行彩色多普勒血流显像检查,观察血管壁、内径、管腔及周围结构,记录血栓形成的部位、大小、栓塞程度,血栓回声特征及管腔血流情况。结果:血栓形成后静脉内径显增宽,管腔不能压瘪,急性血栓表现为均质低回声,慢性血栓为不均质较高回声,血栓部位血流信号消失或充盈缺损。结论:彩色多普勒超声为诊断DVT及观察疗效首选方法。
Objective: To investigate the clinical value of color Doppler ultrasonography in the diagnosis and treatment of lower extremity deep vein thrombosis (DVT). Methods: Color Doppler flow imaging was performed on 77 patients with DVT by color sonography. Blood vessel wall, internal diameter, lumen and surrounding structures were observed. The location, size, embolism, thrombus echogenicity, Cavity blood flow. Results: After thrombosis, the internal diameter of vein was widened, the lumen could not be squashed, the acute thrombus showed homogeneous hypoechoic, the chronic thrombus was hyperhomial, the signal of blood flow in thrombus disappeared or filling defect. Conclusion: Color Doppler ultrasound is the first choice for the diagnosis of DVT and observation of curative effect.
