A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [ 1 ] [ 2 ] These arteries branch from the pulmonary and bronchial arteries , and run together through the center of the segment.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument ( bronchoscope ) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy .
The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as the lingula. Each lobe is further divided up into segments called bronchopulmonary segments. Each lung has a ...
The gloved finger sign has been observed in the imaging of several conditions, including bronchial atresia, cystic fibrosis, bronchiectasis, allergic bronchopulmonary aspergillosis, foreign body aspiration, benign tumors, and malignancies.
Postural drainage is used to treat any condition that causes the build-up of secretions in bronchopulmonary segments. These include: bronchiectasis [2] [3] lung abscesses [2] [3] cystic fibrosis [3] atelectasis [3] chronic obstructive pulmonary disease (COPD) [3] pneumonia [3] postoperative lung damage (after some thoracic surgery) [3] COVID-19 [4]
Segmentectomies are the surgical removal of bronchopulmonary segments and often involve the removal of two adjacent segments. The pulmonary arterial branches to the segments are first identified then divided. Next, stapling is used to divide the segmental bronchi and separate the segments from the lung. [13]
