RESUMO
Management of recurrent malignant pleural effusion associated with trapped lung syndrome remains problematic. An alternative treatment using a pleural catheter has been advocated. Between August 1999 and August 2002, 127 patients underwent thoracoscopy for malignant pleural effusion. Of these, 52 (41%) with trapped lung were managed by insertion of a pleural catheter. Mean age was 66 years (range, 42-89 years). The most frequent diagnosis was breast cancer. Spontaneous pleurodesis (drainage < 10 mL) occurred in 25 (48%) patients whose catheter was removed after 30 to 255 days (mean, 93.8 days). Symptomatic relief was achieved in 49 (94%) patients. Mean dyspnea score improved significantly from 3.0 to 1.9. Complications comprised catheter blockage, surgical emphysema, cellulitis, and loculated effusion in 2 patients each. Mean length of hospital stay was 3 days (range, 1-16 days). Median survival was 126 days (range, 10-175 days). We conclude that long-term placement of a pleural catheter provides effective palliation for malignant pleural effusion associated with trapped lung syndrome.
