Hemoptysis

Definition

Hemoptysis refers to the expectoration of blood originating from the lower respiratory tract. It ranges from small blood-streaked sputum to massive, life-threatening bleeding. The source is typically the bronchial circulation, although pulmonary circulation may also contribute in certain conditions.

Anatomy and Blood Supply of the Lungs

The lungs have a dual blood supply, which explains the mechanism of bleeding:

  • Bronchial circulation

    • High-pressure system from the aorta
    • Supplies airways and supporting structures
    • Most common source of hemoptysis

  • Pulmonary circulation

    • Low-pressure system from right ventricle
    • Supplies alveoli for gas exchange
    • Bleeding less common but severe when present

  • Anastomoses

    • Connections between bronchial and pulmonary vessels
    • Can enlarge in chronic diseases

Classification of Hemoptysis

Hemoptysis is classified based on severity:

  • Mild hemoptysis

    • Small streaks or minimal blood in sputum

  • Moderate hemoptysis

    • Noticeable blood loss but not life-threatening

  • Massive hemoptysis

    • 200–600 mL in 24 hours

    • Risk of airway obstruction and death

Etiology of Hemoptysis

Infectious Causes

  • Pulmonary tuberculosis
  • Pneumonia
  • Lung abscess
  • Bronchiectasis infections
  • Fungal infections (e.g., aspergillosis)

Neoplastic Causes

  • Lung carcinoma
  • Bronchial adenoma
  • Metastatic tumors

Cardiovascular Causes

  • Mitral stenosis
  • Pulmonary embolism
  • Pulmonary hypertension

Inflammatory Causes

  • Vasculitis (e.g., Wegener’s granulomatosis)
  • Goodpasture syndrome
  • Systemic lupus erythematosus

Trauma and Iatrogenic Causes

  • Bronchoscopy
  • Lung biopsy
  • Chest trauma

Miscellaneous Causes

  • Foreign body aspiration
  • Coagulation disorders
  • Drug-induced (anticoagulants)

Pathophysiology

Hemoptysis occurs due to disruption of blood vessels in the respiratory tract:

  • Chronic inflammation → vessel wall damage
  • Tumor invasion → erosion of vessels
  • Increased vascular pressure → rupture
  • Infection → necrosis and bleeding

Bronchial arteries, being high-pressure vessels, are responsible for most cases of significant bleeding.

Clinical Presentation

Symptoms

Hemodynamic Changes in Hemoptysis

In significant cases of Hemoptysis, the body undergoes important physiological changes:

  • Acute blood loss

    • Reduction in circulating blood volume
    • Leads to decreased oxygen delivery

  • Compensatory mechanisms

    • Increased heart rate (tachycardia)
    • Peripheral vasoconstriction

  • Severe cases

    • Hypovolemic shock
    • Multi-organ dysfunction if untreated

Airway Obstruction Mechanism

  • Blood accumulates in bronchi

Certain immune-mediated diseases directly damage lung vasculature:

  • Granulomatosis with polyangiitis

    • Leads to alveolar hemorrhage

  • Systemic lupus erythematosus

    • Immune complex deposition
    • Pulmonary involvement causes bleeding

Role of Pulmonary Embolism

Pulmonary embolism can lead to hemoptysis due to:

  • Infarction of lung tissue
