Abstract Background Bilateral pulmonary agenesis is a rare congenital anomaly incompatible with life that can be missed on routine prenatal screening. Prenatal ultrasound diagnosis of this fatal anomaly can aid in prenatal counseling and postdelivery care. Case Study We report the case of a newborn who was born prematurely at 29 weeks gestation and underwent several unsuccessful intubation attempts immediately after delivery. Conclusion Autopsy examination revealed bilateral pulmonary agenesis with a short, blindly ending trachea.

Abstract Background Placental laser equatorialization or “solomonization” during treatment for twin–twin transfusion syndrome (TTTS) is associated with improved pregnancy outcomes. Concern exists, however, about the extent of placental injury caused by the technique, and of its ability to create “dichorionization,” or complete separation of the fetal vascular circuits. Case Study A “solomonized” placenta was histologically examined for depth of cell damage. Solomonization produces complete devascularization of the chorionic plate, but has minimal effect on the underlying villi. The median depth of the effect was 2,823 µm, or
