Intrauterine infarction of a pulmonary segment in a full-term newborn. A case report

Intrauterine pulmonary infarction is extremely rare. In a series of 775 stillborn and newborn infants, only a few cases of acute pulmonary infarction were reported. The authors present the findings from a full-term infant who died at 9 hours of age of a chronic pulmonary infarction. Several pathogenic mechanisms, including the entry of placental thromboplastin into the fetal circulation, are discussed.
