Abstract
CT- and ultrasound-guided catheters were used to locate and drain empyemas in 17 patients, most of whom had failed to improve with conventional chest-tube drainage due to a poorly positioned tube. Fifteen patients (88.2%) were treated successfully, averting surgery or further drainage, and bacteremia in 1 patient was the only complication. Previously unrecognized communications with the bronchi, esophagus, and subphrenic space were demonstrated, and intracavitary tumor biopsy and instillation of a sclerosing agent were performed in several patients. Compared to the tubes used to drain abdominal abscesses, empyema catheters need less irrigation; dionosil is often the preferred contrast agent, the catheter can be withdrawn in one step, and a residual fibrotic or tumor cavity may persist after pus has been evacuated.
