74. A male newborn delivered at 34 weeks' gestation dies of respiratory failure shortly after birth. The pregnancy was complicated by oligohydramnios found in the second trimester. Fetal ultrasonography at that time showed lack of a urinary bladder, and renal agenesis was suspected. Which of the following best describes the mechanism of respiratory failure in this newborn? A) Oligohydramnios associated with hypoplastic ungs B) Oligohydramnios associated with hypoplastic right ventricle C) Oligohydramnios associated with tracheoesophageal fistula D) Renal agenesis associated with insufficient surfactant production E) Renal agenesis associated with tracheal atresia

A 30-year old woman dies after a short illness beginning in the late stages of labor. At autopsy, blood vessels in the lungs contained fetal debris, as did other vessels of multiple organs. Review of clinical history reveals that she had become acutely ill with dyspnea, hypotension, and seizures, and chest X-ray had demonstrated pulmonary edema. This was followed by prolonged hemorrhage from the vagina and generalized bleeding from other sites. The changes that were found within blood vessels most likely are: a. Gas emboli b. Septic emboli c. Amniotic emboli d. Bone marrow emboli e. Fat emboli
