Abstract:
Fetal pleural effusion, a nonspecific accumulation of fluid in the pleural space, is an uncommon anomaly which can be associated with aneuploidy and a range of other structural malformations or genetic syndromes. Spontaneous resolution is not rare and confers a good prognosis. Perinatal outcome is better for those fetuses without hydrops than those presenting with hydrops. A detailed review of the literature indicates that, for fetuses with persistent effusions, in utero intervention (repeated thoracocentesis, intrauterine shunting and pleurodesis) may improve the chances of survival.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
Clinical Manifestations:
Pleura of the Lungs
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
