目的探讨彩色多普勒超声在肺动脉栓塞(PE)的诊断价值。方法 16例肺动脉栓塞患者[均经螺旋CT、核磁共振(MR)及手术证实],对其行经胸超声心动图检查和下肢深静脉彩色多普勒超声检查。主要看右心、室间隔和右室壁的厚度及运动,观察右心系统、主肺动脉及左右分支处是否有血栓状回声及彩色多普勒超声显示的血流情况。结果 16例患者,超声检出肺动脉血栓直接征象9例,右心房内检出条索样活动性血栓4例,肺动脉主干及左肺动脉血栓3例,右肺动脉近端腔内示2例微动血栓,9例下肢深静脉血栓。16例患者三尖瓣不同程度反流,12例肺动脉收缩压6.93~12.40 k Pa。结论彩色多普勒超声是一种快速、便捷、无创的对肺动脉栓塞的诊断方法 ,在肺动脉栓塞的疗效观察及预后判断中具有重要的诊断价值。
Objective To investigate the diagnostic value of color Doppler ultrasonography in pulmonary embolism (PE). Methods Sixteen patients with pulmonary embolism, confirmed by spiral CT, magnetic resonance imaging (MRI) and surgery, were examined by transthoracic echocardiography and deep venous ultrasonography. Mainly to see the right heart, ventricular septum and right ventricular wall thickness and movement, the right heart to observe the system, the main pulmonary artery and left and right branches of the thrombus echo and color Doppler ultrasound showed the blood flow. Results In 16 patients, there were 9 cases of direct pulmonary embolism detected by ultrasound, 4 cases of cord-like active thrombus detected in the right atrium, 3 cases of pulmonary artery trunk and left pulmonary artery thrombosis, 2 cases of minimally invasive thrombus in the proximal pulmonary artery, Nine cases of deep vein thrombosis. Tricuspid regurgitation was observed in 16 patients with different degrees of systole, and systolic blood pressure in 12 patients was 6.93 ~ 12.40 kPa. Conclusion Color Doppler ultrasonography is a rapid, convenient and noninvasive method for the diagnosis of pulmonary embolism. It has important diagnostic value in the observation and prognosis of pulmonary embolism.
