目的分析羊水吸入综合征(AFAS)的临床与计算机X线成像(CR)表现特征,提高其X线诊断水平。方法对诊断明确,资料完整的324例羊水吸入综合征患儿的临床及CR表现进行回顾分析,对其病因病理、临床表现及CR诊断进行讨论。结果根据CR表现,可将AFAS分为轻度、中度及重度三类。轻度46例,中度267例,重度11例。324例AFAS中,伴气胸2例,纵隔气肿2例,肺不张3例,死亡1例。结论胸部X线摄片是诊断AFAS的必不可少的影像学检查方法,CR检查可明显提高其X线诊断阳性率。
Objective To analyze the clinical and computerized radiographic features of amniotic fluid aspiration syndrome (AFAS), and to improve the diagnostic accuracy of X-ray. Methods The clinical manifestations and CR findings of 324 patients with amniotic fluid aspiration syndrome were analyzed retrospectively. The etiology and pathology, clinical manifestations and the diagnosis of CR were analyzed. Results According to CR performance, AFAS can be divided into mild, moderate and severe three categories. Mild 46 cases, moderate 267 cases, severe in 11 cases. 324 cases of AFAS, with pneumothorax in 2 cases, mediastinal emphysema in 2 cases, atelectasis in 3 cases, 1 died. Conclusions Chest radiography is an indispensable imaging method for the diagnosis of AFAS. CR examination can obviously improve the positive rate of X-ray diagnosis.
