pulmonary atelectasis

【 Method 】 Performed BAL at bedside on 31 elderly patients with acute inflammatory pulmonary atelectasis diagnosed by examination of chest X-ray or/ and CT, FOB under electrocardio-surveillance and monitoring of the transcutaneous oxygen saturation.

方法对胸片或/和CT、FOB检查确诊为急性炎性肺不张31例老年患者，在心电监护，经皮血氧饱和度监测下床边行BAL治疗。

Objective : To evaluate the value of needle aspiration biopsy guid ed by CT in pulmonary atelectasis.

目的: 探讨CT导向下肺不张病灶细针穿刺抽吸活检的价值.

Complications were consisted of pneumonia and pulmonary atelectasis ( 2 cases), simple empyema ( 1 case), thoracic region incisal infection ( 2 cases), transient bucking and hoarseness ( 4 cases).

Light microscope ( HE): PQ group shows that focal pulmonary hemorrhage, alveolar wall thickening apparent, alveolar and interstitial pulmonary edema, inflammatory cell infiltration, and some sections can be seen focal atelectasis, emphysema.

光镜检查：PQ组可见肺灶性出血，肺泡壁明显增厚，肺泡和肺间质水肿，大量炎性细胞浸润，部分切片可见灶状肺不张，肺气肿。

On pulmonary CT/ high-resolution CT ( HRCT), patchy opacity and bronchial wall thickening were seen in each patient. Areas of air trapping were seen in three cases. Bronchiectasis was seen in 2 cases, atelectasis and mosaic perfusion were seen respectively in one case.
