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.
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.
This methodology provided a permanent specimen which could be measured, photographed, or even colorfully painted to delineate the bronchopulmonary segments. Bronchial artery casting techniques, modified and refined by Liebow and his colleagues, demonstrated the importance of dual circulation in the lung, particularly in inflammatory diseases of ...
The lobar bronchi branch into tertiary bronchi also known as segmental bronchi and these supply air to the further divisions of the lobes known as bronchopulmonary segments. Each bronchopulmonary segment has its own (segmental) bronchus and arterial supply. [8] Segments for the left and right lung are shown in the table. [5] The segmental ...
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 ...
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress. [15]
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1]
Bronchopulmonary nodes (hilar nodes) situate in the hilum of each lung. Pulmonary nodes are embedded the lung substance on the larger branches of the bronchi. The afferents of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart ; some of the efferents of the posterior mediastinal glands also ...
