摘要

十一位10歲以下患慢性肺不張之兒童，經保守性治療無效，用肺部電腦斷層攝影及小兒軟式氣管鏡檢查其致病原因，本研究發現其中四位小於一歲之幼童有右肺上葉後枝不張及可見二支分枝。一例由於肺動脈擴張壓迫氣管造成之肺不張，兩位有神經性肌肉病變之病童有多肺葉性肺不張。軟式氣管鏡檢查對氣管內無阻塞之肺不張有診斷之價值，但無治療效果。對於兒童期之慢性肺不張，吾等醫師應多加注意及進一步檢查，如果能夠深入探討其致病機轉，可讓此等病人得到更好之治療效果。

A heterogeneous group of]] children with atelectasis persisting longer than one month were investigated for the causes using chest computed tomography and fiberoptic bronchoscope. Four young infants had right upper lobe (RUL) posterior segmental atelectasis simulating RUL lobar collapse in plain chest films; all had only two visible segmental bronchi by bronchoscopic examination. Intráluminal obstruction in the central airway was not a common cause of pediatric chronic atelectasis in this small series of patients. Only one obstructive atelectasis caused by dilated pulmonary arteries was detected in this study. Two patients with pre-existing neuromuscular diseases showed multiple atelectasis. The atelectatic lobes do not spontaneously re-inflate following flexible bronchoscopy. Investigations involving a larger number of cases are needed to substantiate the etiologies and to guide specific therapy for those children with chronic atelectasis.
