RESUMO
INTRODUCTION: Parapneumonic effusions, as a complication of inflammatory processes in the lungs, usually have a good course, but they sometimes progress into pulmonary empyema, thus becoming a significant clinical problem. OBJECTIVE: To review clinical and radiological features, as well as diagnostic and therapeutic options in parapneumonic effusions. METHODS: The analysis included 130 patients with parapneumonic effusions hospitalized at the General Pulmonology Clinic of the Institute for Pulmonary Diseases of Vojvodina, Sremska Kamenica during 2013. RESULTS: Of 385 patients with pneumonia, 130 (33.8%) had parapneumonic effusion, 78 (60.0%) of whom were males. Most patients (361; 27.7%) were 60-69 years of age. The most common symptoms included fever (92; 70.8%) and cough (91; 70.0%). Hypertension was the most common comorbidity registered in 81 (62.3%) patients, and chronic obstructive pulmonary disease present in 33 (25.4%) patients. Pleural puncture was performed in 62 (47.7%) patients. Macroscopically, effusion was clear in most cases (31; 50.0%), and cytologically the mixed type was most frequently established (26; 41.9%). Bronchoscopy was performed in 52 (40.0%) patients, and video-assisted thoracoscopy in 9 (6.9%) patients. Empyema signs were registered in 13 (10.0%) patients; in all a thoracic drainage with administration of intrapleural streptokinase was performed. CONCLUSION: Patients with a parapneumonic effusion have the symptoms of acute respiratory infection and frequent concomitant diseases. Further diagnostic and therapeutic treatment depends on pleural fluid features and chest CT finding.
