肺不张与许多原因引起的通气不足有关,而不代表任何特异的疾病,也不提示任何特异的病因;肺不张的病因复杂,但主要还是肺癌,炎症和结核,据报道;不同年龄组的365例肺不张中,肺癌居首位,占43.6％,炎症占39.5％,结核占11.5％,其余各种病因仅占5.4％。我院92例肺不张中肺癌占60.9％,炎症占31.5％,结核占5.4％,其余各种病因占2.2％,与资料基本相符。本组92例病人中多系中老年患者,肺癌56例,发病率较其他人群为高,表明中老年患者肺不张多由肺癌所致。
Atelectasis is associated with a number of causes of hypoventilation but does not represent any specific disease nor does it suggest any specific cause; the etiology of atelectasis is complex but is predominantly lung, inflammation and tuberculosis, reportedly by age group Of 365 cases of atelectasis, lung cancer ranks first, accounting for 43.6%, inflammation accounted for 39.5%, tuberculosis accounted for 11.5%, the remaining various causes only 5.4%. 92 cases of atelectasis in our hospital accounted for 60.9% of lung cancer, inflammation accounted for 31.5%, tuberculosis accounted for 5.4%, the remaining various causes accounted for 2.2%, consistent with the data. This group of 92 patients with multi-line elderly, lung cancer in 56 cases, the incidence rate is higher than the other groups, indicating that elderly patients with atelectasis mostly caused by lung cancer.
