A pulmonary sequestration is a medical condition wherein a piece of tissue that ultimately develops into lung ... During this minimally invasive fetal intervention, a ...
Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a congenital disorder of the lung similar to bronchopulmonary sequestration. In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue.
Causes of pulmonary hypoplasia include a wide variety of congenital malformations and other conditions in which pulmonary hypoplasia is a complication. [1] These include congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, fetal hydronephrosis, caudal regression syndrome, mediastinal tumor, and sacrococcygeal teratoma with a large component inside the fetus.
It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates. [2] [3] It consists of a period of tachypnea (rapid breathing, higher than the normal range of 30–60 times per minute). Usually, this condition resolves over 24–72 hours.
The lecithin–sphingomyelin ratio is a marker of fetal lung maturity. The outward flow of pulmonary secretions from the fetal lungs into the amniotic fluid maintains the level of lecithin and sphingomyelin equally until 32–33 weeks gestation, when the lecithin concentration begins to increase significantly while sphingomyelin remains nearly the same.
Hydrops fetalis or hydrops foetalis is a condition in the fetus characterized by an accumulation of fluid, or edema, in at least two fetal compartments. [ 1 ] [ 2 ] By comparison, hydrops allantois or hydrops amnion is an accumulation of excessive fluid in the allantoic or amniotic space , respectively.
Chest congestion is usually caused by excess mucus in the airways, says Meilan King Han, M.D., M.S., professor of medicine and chief of the Division of Pulmonary and Critical Care at the ...
The EXIT procedure, or ex utero intrapartum treatment procedure, is a specialized surgical delivery procedure used to deliver babies who have airway compression. [1] Causes of airway compression in newborn babies result from a number of rare congenital disorders, including bronchopulmonary sequestration, congenital cystic adenomatoid malformation, mouth or neck tumor such as teratoma, and lung ...
