Extravasation From lung

Asthma is a chronic inflammatory condition characterized by bronchial hyper-responsiveness and reversible airway obstruction. Cytokine release from a variety of cell types such as eosinophils, lymphocytes and other inflammatory cells produces epithelial sloughing, plasma protein extravasation from the tracheobronchial microcirculation and airway remodeling. Bronchial mucosal inflammation is present in all patients. The primary goal of asthma management is to maintain control of the disease process by reducing symptoms and improving lung function. 

Due to hemoconcentration from fluid extravasation into lungs... 

Pulmonary hemorrhage secondary to irradiation even in the absence of residual or recurrent lung cancer can be controlled by selective embolization of the causative branches of the bronchial or pulmonary arteries. The site of bleeding can be established or confirmed by bronchoscopy. Frequently, extravasation of contrast material from a particular branch is not identified, but there is local hypervascularity or abnormal vessels in the area of the bleeding. Embolization of these arteries may adequately control the hemorrhage.
