1 Μαΐ 2024 · The pulmonary arteries accompany the bronchi on their course towards the periphery and thus there are lobar, segmental and subsegmental branches. Differentiation can be made by tracing the arterial divisions in correlation to the bronchi.
23 Ιουλ 2024 · Bronchopulmonary segmental anatomy describes the division of the lungs into segments based on the tertiary or segmental bronchi. Gross anatomy. The trachea divides at the carina forming the left and right main stem bronchi which enter the lung substance to divide further.
7 Νοε 2023 · Atelectasis describes the loss of lung volume due to the collapse of lung tissue. It can be classified according to the pathophysiologic mechanism (eg, compressive atelectasis), the amount of lung involved (eg, lobar, segmental, or subsegmental atelectasis), or the location (ie, specific lobe or segment location).
20 Δεκ 2016 · Therefore, the aim of this work was to assess the degree of expiratory 3 rd generation bronchial lumen collapsibility in patients with severe COPD using chest-computed tomography (CT), to evaluate emphysema-phenotype, lobar volumes and correlate results with pulmonary function tests.
1 Μαΐ 2021 · The bronchus of the middle lobe (ML) bifurcates into lateral (B4) and medial (B5) bronchi. The lobar bronchus of the RLL branches into five segmental bronchi: superior (B6), medial basal or paracardiac (B7), anterior basal (B8), lateral basal (B9) and posterior basal (B10).
When the retained secretions with an air bronchogram pattern are present only to the extent of segmental bronchi causing lobar atelectasis. when standard chest physiotherapy has been failed to produce a positive outcome.
9 Οκτ 2023 · New segmental or more proximal airway nodules with a lack of benign features are classified as Lung-RADS 4A with a recommendation of 3-month low-dose CT (LDCT) to assess for resolution (A1: left main stem nodule [arrow], A2: left lower lobe segmental bronchus nodule [arrow]).
