【摘要】 不伴有梗塞之肺血栓栓塞症并非少见,本文报告6例,所有病例在症状出现之初即拍胸片,经仔细读片发现,全部病例肺野内均见到不同范围与程度的缺血征象,此征比其他征象敏感且随症状之改善而减小或消失。我们认为,当患者被临床怀疑为肺血栓栓塞时,应立即拍胸片,以便明确有无原有病变和肺部并发症,并找出有无缺血征象。这将有利于及时诊断。当然,结合有确切血栓形成条件,相应的ECG 和血气分析资料,是可以确诊的。如能结合肺灌流扫描则更好。更多还原

【Abstract】 The chest films of 6 cases withpulmonary embolism without infarc-tion were investigated.It is consi-dered that a probable diagnosis couldbe made timely by combining the ra-diographic findings with the exactpredisposed embolic condition.Amongseveral X ray signs,the oligemia si-gn is the most common and early ap-pearance,and it responses to treat-ment sensitively.Therefore,one sh-ould pay attention to the meaning ofchest radiographs in diagnosing pul-monary embolism.更多还原
