尽管没有确切的证据,但临床经验表明胸部X线片正常而有严重呼吸困难的患者可能患有肺栓塞(PE)。本文探讨床旁检查和肺通气/灌注扫描对这类患者PE的诊断价值。方法入选标准是:症状出现后24小时内,提示有急性PE;年龄≥18岁。根据肺动脉造影和转归分类确诊为PE的260例患者中20例胸片正常(PE组);排除PE的642例患者中113例胸片正常(无PE组)。本研究对133例胸片正常者进行评估。在24小时内摄取胸部后前位和侧位片,并记录12导联心电图。病史和体捡在肺通气/灌注扫描之
Although there is no definitive evidence, clinical experience shows that patients with normal chest radiographs and severe dyspnea may have pulmonary embolism (PE). This article discusses the bedside examination and lung ventilation / perfusion scan for the diagnosis of PE in such patients. Methods Inclusion criteria were as follows: Within 24 hours after the onset of symptoms, acute PE was indicated; age> 18 years. Of the 260 patients diagnosed with PE by pulmonary angiography and classification, 20 had normal chest radiographs (PE group); 113 of the 642 patients who had PE excluded had normal chest radiographs (no PE group). The study of 133 cases of normal chest X-ray assessment. In 24 hours after the intake of chest anterior and lateral films, and record 12-lead ECG. History and body picking in lung ventilation / perfusion scan
