超声心动图检查在肺栓塞诊断中的应用

肺栓塞（PE）是一种发病率和病死率较高的急危重病,临床上有多种检查方法可以帮助诊断。超声心动图在明确PE的临床类型、评价PE的血流动力学改变和随访治疗效果等方面具有重要价值。临床上主要应用经胸廓超声与经食管超声检查,两者均有较高的敏感性和特异性。相比其他影像学检查,超声心动图对急性PE患者的处理效果更好。文章就超声技术在PE诊断中的应用价值以及国内外的研究进展作一综述。

Clinical value of echocardiography in diagnosis of pulmonary embolism

Pulmonary embolism is an emergency condition with high morbidity and mortality, and many methods can help to diagnosis pulmonary embolism. Echocardiography is of great value in the determination of clinical types of PE and evaluation of hemodynamics of PE and therapeutic effect. Transthoracic echocardiography and transesophageal echocardiography are commonly used clinically, and both possess relatively higher sensitivity and specificity. Echocardiography outperforms the other imaging examinations in the diagnosis of acute pulmonary embolism. The roles of echocardiography in the diagnosis of pulmonary embolism are reviewed in this article.
