Abstract:
Blood supply of the tracheobronchial tree is derived from a dual system involving pulmonary and bronchial circulation. Various primary and secondary abnormalities of central airway vasculature can present with patterns that are distinct during bronchoscopy. These patterns maybe visualized during bronchoscopic evaluation of a patient with hemoptysis or as an incidental finding during an airway examination for other indications. Thorough knowledge of airway vasculature abnormalities and recognition of possible underlying pathophysiology is vital for the bronchoscopist. This review is a comprehensive description of vascular anatomy of the airway and the different vascular abnormalities that can be encountered during bronchoscopy.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
