Hemoptisis Clinical Trial
Hemoptysis is defined as the expectoration of blood from respiratory tract, a spectrum that
varies from blood-streaking of sputum to coughing up large amounts of pure blood.
Massive hemoptysis variably defined as the expectoration of 100-600 ml over 24-h period.
The most common site of bleeding is the tracheobronchial tree, which can be affected by
inflammation (acute or chronic bronchitis, bronchiectasis) or by neoplasm ( bronchogenic
carcinoma, endobronchial metastatic carcinoma, bronchial carcinoid tumor). The bronchial
arteries, which originate either from aorta or from intercostal arteries, and are part of
the high-pressure systemic circulation, are the source of bleeding in bronchitis or
bronchiectasis or endo bronchial tumors.
