Neonatal Pulmonary Infarction

Chronic Intrauterine Meconium Aspiration Causes Fetal Lung Infarcts, Lung Rupture, and Meconium Embolism

“…Definite MA was seen in two [8,26], and a third had presumed amniotic fluid aspiration [13]. Plateinfarcts are illustrated in three cases [13,24,26].…”

“…Definite MA was seen in two [8,26], and a third had presumed amniotic fluid aspiration [13]. Plateinfarcts are illustrated in three cases [13,24,26]. There is evidence that meconium-induced vasoconstriction causes intrauterine hypoxia by compromising umbilical cord or placental blood flow [27][28][29], although some investigators dispute this [30,31].…”

“…Three monozygotic twins [24,25] and three singletons with fetal lung infarcts, including case 3, have been previously reported [8,13,14,26]. Definite MA was seen in two [8,26], and a third had presumed amniotic fluid aspiration [13]. Plateinfarcts are illustrated in three cases [13,24,26].…”
