Interventional radiology treatment of empyema and lung abscesses

Pneumonias in children can be complicated by pleural effusions, empyema and abscesses. The incidence of these complications is increasing, correlated to an increased virulence of the pneumococcal bacterium. These complications may prolong morbidity and lead to decreased pulmonary function. Traditionally, patients were treated medically with antibiotics, and refractory complications were treated surgically with large bore chest tube placement and thoracotomy. Improvements included instilling fibrinolytics into the chest tubes and video-assisted thoracoscopic surgery, which expedited recovery and improved outcomes. Image guided techniques from interventional radiology have been developed as an alternative to treat these patients with minimal invasiveness. These therapies have achieved high success and low complication rates, and are the preferred first-line procedures when available.
