ObjectiveTo determine the usefulness and the results of a strategy using intrapleural streptokinase (SK) instillation guided by repeated computed tomography (CT) scan examinations in pleural empyemas unresponsive to chest tube drainage.DesignA retrospective chart review.SettingThe medical Intensive Care Unit and Department of Radiology, in a university hospital.PatientsSixteen patients with empyema who had a persistent pleural effusion despite drainage, among 37 patients with infectious pleural effusion.InterventionsIn the 16 patients, CT examination was performed before and at least once after SK. Intrapleural SK was instilled, either through the chest tube or via a needle puncture, according to the CT scan results.ResultsThe first CT scan confirmed a persistent effusion in all, showing a multiloculated effusion in 13 patients, and an ectopic loculus in one. The first SK instillation resulted in a dramatic increase of fluid drained per day (from 68 +/- 28 ml to 567 +/- 262 ml; p < 0.001), leading to complete resolution in 11 patients, while the others required a second CT scan-guided procedure. In one, the chest tube was misplaced, while in two, transparietal injection was needed. Finally, a complete resolution was observed in 14 (87.5%) of the patients. Two patients had a poor initial response to SK and were eventually scheduled for video-thoracoscopy. A single episode of chills and fever was observed among 32 SK instillations.ConclusionCT-guided SK instillation in pleural empyema appears to be safe, and allowed complete resolution in 87.5% of our patients.
