How do you treat diffuse alveolar hemorrhage?
Treatment for DAH involves three major disciplines: (1) supportive care including hemodynamic correction, transfusion, and ventilator support, ranging from oxygen supplementation to mechanical ventilation with high positive end-expiratory pressure (PEEP) producing a tamponade effect to limit capillary bleeding; (2) …
What is damaged in diffuse alveolar damage?
Diffuse alveolar damage (DAD) is a stereotyped response to injury in lung tissue. DAD consists of an intra-alveolar exudate (often described as hyaline membrane) in association with marked hyperplasia of type II pneumocytes that may appear cytologically bizarre and pleomorphic (Fig. 8-2).
What causes diffuse alveolar hemorrhage?
Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases such as anti-neutrophil cytoplasmic antibody-associated vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus, but DAH may also result from coagulation disorders, drugs, inhaled toxins, or …
What happens in diffuse alveolar hemorrhage?
DAH is a distinct clinicopathologic syndrome of pulmonary hemorrhage that originates from the pulmonary microcirculation, including the alveolar capillaries, arterioles, and venules. It presents with hemoptysis, anemia, diffuse lung infiltration, and acute respiratory failure.
What is alveolar haemorrhage?
Alveolar hemorrhage is the rarest pulmonary complication of catastrophic antiphospholipid syndrome and is associated with high mortality risk. This life-threatening complication results from autoimmune damage to the alveolar blood vessels.
What is a alveolar hemorrhage?
Abstract. Alveolar hemorrhage is the rarest pulmonary complication of catastrophic antiphospholipid syndrome and is associated with high mortality risk. This life-threatening complication results from autoimmune damage to the alveolar blood vessels.
What causes hemorrhage in lungs?
Bleeding from one area of the lung (localised bleeding) infections such as pneumonia, tuberculosis or cystic fibrosis. congenital lung malformations. physical trauma, for example injury in a car crash. a weakness in the blood vessels.

What causes lungs to hemorrhage?
Bleeding from one area of the lung (localised bleeding) Causes of localised pulmonary haemorrhage include: infections such as pneumonia, tuberculosis or cystic fibrosis. congenital lung malformations. physical trauma, for example injury in a car crash.
What is diffuse bleeding?
Diffuse alveolar hemorrhage is persistent or recurrent pulmonary hemorrhage. There are numerous causes, but autoimmune disorders are most common. Most patients present with dyspnea, cough, hemoptysis, and new alveolar infiltrates on chest imaging. Diagnostic tests are directed at the suspected cause.
Can a lung hemorrhage be cured?
Localized pulmonary bleeding usually requires local treatment, like bronchoscopic therapy, bronchial artery embolization or surgery. Diffuse alveolar haemorrhage must be treated systemically, i. e. by immunosuppressive therapy in cases of vasculitis or by medical treatment of coagulation disorders.
