123例无心肺疾病的急性肺栓塞(PE)患者的胸部平片异常与肺动脉平均压、动脉血氧分压和肺泡-动脉氧分压差有关。中央肺动脉突出或心脏肥大患者的肺动脉平均压高于肺不张、肺实质异常或胸腔积液患者(p < 0.001)。这些影像学表现提示了急性肺栓塞时肺动脉高压的严重程度,并提示肺梗死或肺出血与肺栓塞的严重程度较轻有关。
Abnormalities of the plain chest radiograph of 123 patients with acute pulmonary embolism (PE) and no prior cardiac or pulmonary disease were related to the pulmonary arterial mean pressure, the partial pressure of oxygen in arterial blood, and the alveolar-arterial oxygen gradient. Patients with either a prominent central pulmonary artery or cardiomegaly had higher pulmonary arterial mean pressures than did patients with atelectasis, a pulmonary parenchymal abnormality or pleural effusion (p < 0.001). These radiographic findings give clues to the severity of pulmonary hypertension in acute PE and suggest that pulmonary infarction or hemorrhage is associated with less severe PE.
