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 ].

Bronchopulmonary sequestration (BPS) is another type of fetal lung lesion that share some similarities to CPAM, but also some important differences. BPS lesions do not contain cysts and are formed from normal lung tissue that does not connect to the airway. As a result, a BPS does not contribute to gas exchange after birth like the normal lung.

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.

Bronchopulmonary sequestration (BPS) consists of nonfunctional lung tissue that has its own blood supply. In BPS, the abnormal lung tissue does not communicate with the tracheobronchial tree. The sequestered lung may lie within the fetal chest, or in …

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.

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.

The most common masses seen in the fetal chest are congenital diaphragmatic hernia (CDH), congenital cystic adenomatoid malformation (CCAM), and bronchopulmonary sequestration (BPS) (1). During the course of pregnancy, space-occupying lesions may enlarge rapidly or grow commensurately with the fetus.

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 ...
