Jul 2, 2024 · Bronchiectasis (plural: bronchiectases) is defined as an irreversible abnormal dilatation of the bronchial tree. It has a variety of underlying causes, with a common etiology of chronic inflammation. High-resolution CT is the most accurate modality for diagnosis. Epidemiology.
May 9, 2018 · Chest x-rays are usually insufficient in the diagnosis and management of bronchiectasis. May be normal or may show dilated bronchi with thickened walls (tram-track sign). An air-fluid level may be seen in severe cystic bronchiectasis. CT. High-resolution CT is the gold standard for diagnosis.
May 22, 2023 · Bronchiectasis is a chronic lung disease characterized by persistent and lifelong widening of the bronchial airways and weakening of the function mucociliary transport mechanism owing to repeated infection contributing to bacterial invasion and mucus pooling throughout the bronchial tree.
Aug 10, 2022 · This article reviews the presentation, diagnosis, and treatment of bronchiectasis, a syndrome of abnormal airways that results in chronic cough, sputum production, and respiratory impairment.
Jan 11, 2024 · Chest radiograph (CXR) is less sensitive than a computed tomography (CT) of the chest for identifying the bronchiectatic airways and can miss early bronchiectasis. CXR is however the primary imaging modality for respiratory illnesses and can identify dilated airways as “tram-tracks” or cystic lucencies with or without air-fluid levels.
Dec 28, 2018 · The full Guideline for Bronchiectasis in Adults is published in Thorax. 1 The key features of the guideline are highlighted in a short article published to accompany the full guideline. 2 The following is a summary of the recommendations and good practice points and includes all figures 1–5 and tables 1–7.
May 29, 2015 · Bronchiectasis is permanent irreversible dilatation of the airways and occurs in a variety of pathologic processes. Recurrent infection and inflammation and the resulting chemical and cellular cascade lead to permanent architectural changes in the airways.
Bronchiectasis is diagnosed by identification of abnormal dilation of the airways on imaging. Chest radiograph (CXR) is less sensitive than a computed tomography (CT) of the chest for identifying the bronchiectatic airways and can miss early bronchiectasis. CXR is however the primary imaging
Jul 14, 2021 · Bronchiectasis is defined radiologically as the abnormal widening of the bronchi and bronchioles within the lungs. This radiological feature is often associated with symptoms of chronic productive cough and recurrent respiratory infections leading to the clinical diagnosis of bronchiectasis.
Bronchiectasis on CT imaging is best identified by considering together a lack of airway tapering, enlargement of an airway relative to its accompanying pulmonary artery, and evidence of enlarged airways in the lung periphery. Bronchiectasis patterns and distribution on visual CT evaluation can point to underlying disease causes.
