超声诊断肺动脉栓塞的应用价值

Clinical Application of Ultrasonography in Diagnosing Pulmonary Embolism

目的:探讨超声心动图对肺动脉栓塞的诊断价值。材料和方法:对临床确诊的14例肺动脉栓塞患者进行经胸超声心动图及下肢深静脉超声检查,与肺动脉造影、螺旋CT、磁共振成像或核素肺显像对照。结果:超声心动图发现直接征象者8例,大致正常者2例,重度肺动脉收缩压增高者4例;合并下肢深静脉血栓者12例,合并卵圆孔未闭2例。结论:超声的多项技术联合应用可提高对肺动脉栓塞诊断。

Purpose To evaluate the diagnostic value of ultasonography in patients with pulmonary embolism.Materials and Methods Fourteen patients with confirmed pulmonary embolism underwent transthoracic echocardiography and peripheral vascular ultrasonography.The findings of ultrasonography were compared with those of pulmonary angiography,spiral CT,MRI or radionuclide lung imaging.Results Transthoracic echocardiography detected the thrombus in the pulmonary aeteries on 8 patients,no abnormal findings on 2 cases and pulmonary hypertension on the other 4 cases.Two cases complicated with patent foramen ovale and 12 cases complicated with proximal vein thrombosis on peripheral vascular ultrasonography.Conclusions The combined application of ultrasonic techniques can improve the diagnostic accuracy of pulmonary embolism and its complications.
