Influence of Talc Dose on Extrapleural Talc Dissemination after Talc Pleurodesis

open access: yesAmerican Journal of Respiratory and Critical Care Medicine, 2003
Abstract This study was designed to ascertain, in a rabbit model, extrapleural talc deposition and the related inflammatory response after talc slurry pleurodesis with two clinical doses, 200 and 50 mg/kg. Histopathologic evaluations revealed that whereas numerous rabbits receiving a high dose had talc in the ipsilateral (70%) and ...
