Bronchial atresia is a rare congenital disorder that can have a varied appearance. A bronchial atresia is a defect in the development of the bronchi, affecting one or more bronchi – usually segmental bronchi and sometimes lobar. The defect takes the form of a blind-ended bronchus.
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.
Bronchial atresia is a rare congenital disease characterized by segmental or lobar emphysema and, in some cases, mucoid impaction. The exact cause of bronchial atresia is unknown; the lobar bronchi, subsegmental bronchi, and distal bronchioles develop in the fifth, sixth, and sixteenth weeks of fetal development, respectively.
Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare congenital malformation. PA-IVS involves complete blockage of the pulmonary valve located on the right side of the heart. This blockage prevents the flow of blood to the lungs.
Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a congenital disorder of the lung similar to bronchopulmonary sequestration.
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 mildest variant of pulmonary atresia with ventricular septal defect involves pulmonary atresia with normally developed main pulmonary artery and branch pulmonary arteries, the blood that flows to the lungs from the right side of the heart goes to the left side of the heart through the ventricular septum which then flows through the patent ...
Tricuspid atresia; Tetralogy of Fallot; Total anomalous pulmonary venous return; A mnemonic to remember the conditions associated with right-to-left shunting involves the numbers 1-5, as follows: 1 Combination Vessel: Persistent truncus arteriosus (minimal cyanosis) 2 Vessels involved: Transposition of great vessels; 3 Leaflets: Tricuspid atresia
