肺动脉造影可确诊急性帅栓塞,但造影有一定危险性、费用昂贵;患者的其他情况如肥胖、呼吸配合不好、肺部原发疾病也将影响其诊断价值,根据报导假阴性的发生率甚至高达60—73％。急性肺栓塞的症状和体征常不特异,虽可提示诊断,但其变化多端,故不可靠。要提出的是以往各家所报告的病例大多有心肺疾病并存,故所谓急性肺栓塞表现常混杂有其他心肺疾病的表现。通过总结未并发心肺疾病的急性肺栓塞的临床表现以提高临床诊断
Pulmonary angiography can be diagnosed acute acute embolism, but angiography has some risk, costly; other patients such as obesity, respiratory coordination is not good, the primary lung disease will also affect the diagnostic value, according to the reported incidence of false negative or even Up to 60-73%. The symptoms and signs of acute pulmonary embolism is often not specific, although it may prompt diagnosis, but its varied, it is not reliable. It is to be mentioned that in the past, most cases reported by the families coexisted with cardiopulmonary diseases. Therefore, the so-called acute pulmonary embolism performance is often mixed with other cardiopulmonary diseases. To improve the clinical diagnosis by summarizing the clinical manifestations of acute pulmonary embolism without concurrent cardiopulmonary disease
