ETIOLOGY ANALYSIS OF CASES WITH PLEURAL EFFUSION AND CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Objective: COPD is respiratory system common diseases. Pleural effusion is generally signs in clinical. COPD patients with pleural effusion in clinical are common,its cause is more complex,benign and malignant pleural effusion identified in the clinical and prognosis is great significance.We discussed the cause of our hospital patients with COPD and pleural effusion. To investigate the etiology of pleural effusion and improve the efficiency of diagnosis and differential diagnosis. Methods:We made a retrospective analysis of 87 cases inpatients with COPD and pleural effusion from 2009- 01~ 2010- 12. There were 55 male and 32 female patients with an average age of 67 years. We investigated the etiology of pleural effusion. Results: We diagnosed the effusions with benign origin according to the clinical,radiological examination,quality of pleural effusion or with therapy the patients were cured. Benign pleural effusion 80 cases( 91. 95%), including cardiac dysfunction 41 cases( 47. 13%),hypoalbuminemia 11 patients( 12. 63%),tuberculosis in 7 patients( 8. 05%),pneumonia by pleural effusion in 5 patients( 5. 75%),and pulmonary embolism lead to pleural effusion in 5 patients( 5. 75%),liquid pneumothorax three patients( 3. 45%),pyothorax 1 cases( 1. 14%); Cardiac dysfunction with hypoalbuminemia 7 cases( 8. 05%). According to clinical manifestations, sputum or pleural effusion fall off cytology,fiberoptic bronchoscopic biopsy materials,pleural biopsy microscopic or chest,we had the diagnosis of malignant pleural effusion. Malignant pleural effusion diagnosed 4 cases( 4. 60%),did not make clear diagnosis 3 cases( 3. 45%). Conclusion: Cardiac dysfunction and hypoalbuminemia were major cause leading to chronic obstructive pulmonary disease and pleural effusion.
