Intrapleural Fibrinolytic Therapy With Alteplase for the Management of Multiloculated Malignant Pleural Effusion: A Case Series.

Malignant pleural effusion refers to the presence of fluid in the pleural space due to an underlying malignancy. Malignant pleural effusion is sometimes accompanied by the formation of fibrous adhesions resulting in a multiloculated effusion. This diminishes the efficacy of drainage and makes successful pleurodesis impossible, leaving the patients with severe shortness of breath.
