OVERVIEW:
Definition:
expectoration/ coughing of blood originating from tracheobronchial tree
Sources:
Bronchial arteries (90%): under systemic circulatory pressure to supply supporting structures of the lung → heavier bleeding
Pulmonary arteries (5%): under low pressure to supply alveoli → milder bleeding
Nonbronchial arteries (5%): intercostal arteries, coronary arteries, thoracic/ upper/ inferior phrenic arteries
Quantification:
Mild: <20mL/ 24h
Massive defined anywhere from >300mL-1L/ 24hr
Mortality: 38% for massive (>500mL/ 24hr) vs 4.5% for nonmassive
Etiology (in adults):
Infectious (most common):
Bronchitis
PNA (necrotizing, lung abscess)
TB
Viral
Fungal
Parasitic
Malignancy:
Primary lung cancer vs metastatic disease
Pulmonary:
Bronchiectasis
COPD
PE/ infarction
Bronchopleural fistula
Sarcoidosis
Cardiac:
Mitral stenosis
Tricuspid endocarditis
CHF
Rheumatological:
Goodpasture Syndrome
SLE
Vasculitis (Wegener’s, HSP, Behcet)
Amyloidosis
Hematological:
Coagulopathy/ thrombocytopenia/ platelet dysfunction
DIC
Vascular:

AA
Pulmonary artery aneurysm
Aortobronchial fistula
Pulmonary angiodysplasia
Toxins:
Anticoagulation/ aspirin/ antiplatelets
Penicillamine, amiodarone
Crack lung
Organic solvents
Trauma:
Tracheobronchial rupture
Pulmonary contusion
Other:
bronchoscopy/ lung biopsy
Pulmonary artery or central venous catheterization
Foreign body aspiration
Pulmonary endometriosis (catamenial hemoptysis)
Idiopathic (up to 25% of cases)
Pseudohemoptysis:
Sinusitis
Epistaxis
Rhinorrhea
Pharyngitis
URI
Aspiration
GIB
