The development of pulmonary hypertension (PH) is a serious complication of bronchopulmonary dysplasia (BPD) among infants born at extremely low gestational ages. Bronchopulmonary dysplasia-associated PH is characterized by persistent pulmonary vasoconstriction, progressive right heart dysfunction, and an increased risk of death. We have shown previously that certain placental vascular lesions are associated with BPD-associated PH. Further evaluation of the villous and vascular morphometry of these placentas is warranted. Using digital image analysis (DIA), we compared villous and vascular morphometric parameters of placentas from infants with and without BPD-associated PH. We conducted a case-control study of placentas from 14 infants born at
