2025年1月21日 · Bleeding into the alveolar spaces of the lungs characterizes the syndrome of diffuse alveolar hemorrhage (DAH) and is due to disruption of the alveolar-capillary basement membrane. This disruption is caused by injury or inflammation of the arterioles, venules, or alveolar septal (alveolar wall or interstitial) capillaries.

Diffuse alveolar hemorrhage (DAH) is a life-threatening condition caused by a variety of disorders associated with hemoptysis, anemia, diffuse lung infiltration, and acute respiratory failure.

2021年9月1日 · Exacerbation causing acute diffuse alveolar hemorrhage: Severity ranges from intermittent hemoptysis to life-threatening respiratory failure. ~14% of patients may be critically ill in the acute phase of the disease. Symptoms may include cough (usually with hemoptysis), dyspnea, and fever.

Diffuse alveolar hemorrhage (DAH) is a life-threatening pulmonary complication in patients with hematologic malignancies or systemic autoimmune disorders. Pathologic findings show pulmonary capillaritis, bland hemorrhage, diffuse alveolar damage, ...

Diffuse alveolar hemorrhage is persistent or recurrent pulmonary hemorrhage that originates from the lung parenchyma (ie, the alveoli) as opposed to the airways. There are numerous causes, but autoimmune disorders are most common.

2024年12月19日 · Diffuse alveolar hemorrhage (DAH) is a subset of diffuse pulmonary hemorrhage when bleeding is diffuse and directly into the alveolar spaces. It can occur in a vast number of clinical situations and can be life-threatening.

Diffuse alveolar hemorrhage (DAH) is a clinical syndrome characterized by generalized intra-alveolar bleeding originating from the pulmonary microcirculation. The finding of DAH carries an extended differential diagnosis and may be associated with a number of histopathologic patterns.

2009年8月27日 · Diffuse alveolar hemorrhage (DAH) is a clinicopathologic syndrome describing the accumulation of intraalveolar RBCs originating from the alveolar capillaries. All causes of DAH have the common denominator of an injury to the alveolar microcirculation.

2020年11月3日 · Diffuse alveolar hemorrhage is an acute, life-threatening event, and repeated episodes can lead to organizing pneumonia, collagen deposition in small airways, and, ultimately, fibrosis difficult to diagnose and uncommon, requiring a high index of suspicion

Diffuse Alveolar Hemorrhage (DAH) is a life-threatening condition; It is a subset of Pulmonary hemorrhage involving the microcirculation involving alveolar microvasculature; Most commonly the result of systemic vasculitis ; Clinical Features. Hemoptysis (may be initially absent in up 33% of DAH presentations) Anemia; Diffuse lung infiltrates
