Bronchopulmonary sequestration, also known as BPS or pulmonary sequestration, is a rare birth defect in which an abnormal mass of nonfunctioning lung tissue forms during prenatal development. It can form outside (extralobar) or inside (intralobar) the lungs, but is not connected directly to the airways.

2025年1月8日 · Bronchopulmonary sequestration (BPS), sometimes referred to simply as pulmonary sequestration, is a rare congenital abnormality of the lower airway. It consists of a nonfunctioning mass of lung tissue that lacks normal communication with the tracheobronchial tree and that receives its arterial blood supply from the systemic circulation [1].

2024年11月10日 · KEY FACTS Terminology • Bronchopulmonary tissue that does not connect to tracheobronchial tree or pulmonary arteries Imaging • Homogeneously echogenic lesion adjacent to diaphragm Typically triangular and well defined but can fill hemithorax and be difficult to differentiate from compressed lung • Color Doppler key: Prominent feeding ...

BPS lesions get their blood supply from a feeding vessel arising directly from the aorta as opposed to the blood supply to the normal lung. The identification of a feeding vessel helps to distinguish a BPS from a CPAM.

2024年2月1日 · Bronchopulmonary sequestration (BPS) and congenital pulmonary airway malformation (CPAM) are the 2 most common echogenic chest masses discovered incidentally during routine ultrasound scans in the second trimester. This paper describes BPS and differentiates it from CPAM sonographically in utero.

先天性肺部肿块包括支气管肺隔离症 (bronchopulmonary sequestration, BPS；又称肺隔离症)、先天性肺气道畸形 (congenital pulmonary airway malformation, CPAM)、先天性肺叶过度膨胀 (congenital lobar overinflation, CLO)、支气管源性囊肿和支气管闭锁。

2 天之前 · Bronchopulmonary Sequestration Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract. It consists of a nonfunctioning mass of normal lung tissue that lacks normal communication with the tracheobronchial tree, and that receives its arterial blood supply from the systemic circulation.

2019年7月7日 · Bronchopulmonary sequestration (BPS) is a solid lung lesion of nonfunctioning pulmonary tissue, a supernumerary lobe of the lung, which lacks connection to the tracheobronchial tree and receives its blood supply from an aberrant systemic feeding artery, originating commonly from the descending aorta.

2003年11月17日 · Bronchopulmonary sequestration (BPS) is a nonfunctioning bronchopulmonary tissue that is separate from the tracheobronchial tree and receives arterial blood from the systemic circulation. BPS has a wide spectrum of imaging findings. Surgery is generally indicated for the treatment of BPS.

Bronchopulmonary sequestration (BPS) is a congenital malformation of the lower respiratory tract in which a portion of the lung develops without connection to the normal airways. It also has an abnormal blood supply derived from the aorta. BPS is a rare condition, comprising less than 5% of all congenital lung abnormalities.
