Massive haemoptysis DDx
- Haemoptysis is the symptom of coughing up blood. Massive haemoptysis has no generally accepted definition. Suggested volumes range from 100 mL to more than 1000 mL.
- A more relevant definition of massive haemoptysis is the volume that is life threatening by virtue of airway obstruction or blood loss (anatomical dead space is only 100-200 mL)
- Origin is bronchial circulation in 95%, and pulmonary circulation in 5%.
- Alveolar haemorrhage rarely causes massive haemoptysis
Chronic inflammatory conditions (including bronchiectasis, tuberculosis, lung abscess) and lung malignancies are the most common causes
- Mycobacteria, particularly tuberculosis
- Fungal infections (mycetoma)
- Lung abscess
- Necrotising pneumonia (Klebsiella, Staphylococcus, Legionella)
- Swan-Ganz catheterisation
- Transbronchial biopsy
- Transtracheal aspirate
- Hydatid cyst
- Blunt/penetrating injury
- Suction ulcers
- Tracheo-arterial fistula
- Bronchogenic carcinoma
- Bronchial adenoma
- Pulmonary metastases
- Bronchial adenoma
- Foreign body aspiration
- Vascular anomalies
- Pulmonary infarct, embolism
- Mitral stenosis
- Arteriobronchial fistula
- Arteriovenous malformations
- Bronchial telangiectasia
- Left ventricular failure
- Von Willebrand’s disease
- Anticoagulant therapy
- Platelet dysfunction
- Disseminated intravascular coagulation
- Behcet disease
- Granulomatosis With Polyangiitis (GPA, Wegener granulomatosis)
- Bronchiectasis (including cystic fibrosis)
- Chronic bronchitis
- Emphysematous bullae
- Catamenial (endometriosis)
