54 cases of pulmonary tuberculosis which had been given unilateral artificial pneumothorax for more than 3 months without other surgical therapies were presented for our observations at more than 6 months after the termination of the artificial pneumothorax.
Results:
1) Relationship between the incidence and the degree of pulmonary contraction No contraction in 20.4%; slight contraction (5 to 20%) in 18.5%; moderate contraction (25 to 60%) in 51.9%; marked contraction (more than 65%) in 9.2%.
2) Relationships between the duration of the pneumothorax therapy and the degree of pulmonary contraction: Cases which had less than 12 months of pneumothorax gave none or slight one, while the cases which had more than 12 months of pneumothorax had remarkable one.
3) Relationship between the extent of the disease (graded by the classification of the National Tuberculosis Association) and the degree of contraction: Minimal showed none or slight one, moderately and advanced showed more or less remarkable one.
4) Relationship between the density of x-ray shadow and the degree of contraction: Slight shadow cases hed none or slight one, heavy shadow cases hed marked one.
5) Relationship between x-ray findings of endobronchial diseases and the degree of contraotion: 0% in non-contraction group; 50% in slight contraction; 82% in moderate contraction group; 100% in marked group.
6) Relationship between the opaque lung and the incidence and degree of contraction: 65% of opaque lung was found in unexpandable lung. partial opacification of upper lobs showed slight contraction; general opacification showed noderate contraction and massive opaque lung showed remarkable contraction. Cases of continuous opaque lobe showed marked contraction. The longer the duration of opacification, the higher the degree of contraction.
7) Relationship between the pleural effusion and the degree of contraction: Generally, the more the effusion, the higher the degree of contraction.
