title: Placental and umbilical cord macroscopic changes associated with fetal and maternal events in the hypertensive disorders of pregnancy.
abstract: OBJECTIVE
  The purpose of this study was to identify placental and umbilical cord macroscopic changes and correlate them to maternal and fetal clinical events in hypertensive disorders of pregnancy (HDP).
  
  
  METHODS
  The authors examined 150 placentas, 30 from each HDP group, totaling 120, and 30 from the control group. All placentas and umbilical cords were examined, recorded, and photographed.
  
  
  RESULTS
  The mean placental weight in the control group (526.3 +/- 95.6 g) was greater than in the HDP (435.5 +/- 43.1 g). Calciphylaxis was the most common macroscopic change found in the control and HDP groups in 27 (90%) and 118 cases (98.3%), respectively.
  
  
  CONCLUSIONS
  Pregnant women with HDP were relatively younger. In addition, due to low blood flow seen in HDP, the macroscopic changes found included lower placental weight, calciphylaxis in the maternal surface, and fibrin in the fetal surface. Because of all complications associated, most women with HDP had preterm infants who developed respiratory problems and had shorter umbilical cords.
