Résumé
<p><b>OBJECTIVE</b>To study the clinical characteristics and treatment method of pneumonoconiosis with spontaneous pneumothorax.</p><p><b>METHODS</b>The clinical data of 55 cases with spontaneous pneumothorax were analyzed.</p><p><b>RESULTS</b>Among these 55 cases, there were 19 cases with left side pneumothorax, 25 cases with right side pneumothorax and 11 cases with bilateral pneumothorax. The lungs of 17 cases were compressed to less than 20%, the lungs of 29 cases were compressed to 20% ∼ 50% and the lungs of 9 cases were compressed to more than 50%, 17 cases were treated conservatively, 7 cases were treated by thoracentesis, and 32 cases were treated by closed thoracic drainage, including 10 cases intrapleural injected with thrombin and PAMBA. After the treatment, 41 cases were cured, 10 cases were improved, 3 cases were transferred to other hospital for plugging or pleurodesis and 1 case died of the respiratory failure.</p><p><b>CONCLUSION</b>The clinical symptoms of cases with pneumonoconiosis and spontaneous pneumothorax are atypical. These cases easily recur. After treatment, the healing of these cases is better.</p>
