Abstract
Background: Placental examination is important for its diagnostic immediacy to correlate with maternal and/or fetal complications and parturitional difficulties. In a broader context, clinicopathologic studies of the placenta have addressed a range of pathogenetic questions that have led to conclusive and inconclusive results and interpretations. Methods: Recent standardized morphologic criteria and terminology of placental lesions have facilitated the ability to compare findings from studies that have focused on complications and outcomes of pregnancy. This review is an evaluation of recent studies on placental lesions associated with hypoxic-ischemic encephalopathy (HIE). Conclusion: No apparent consensus exists on whether it is fetal inflammation with the release of cytokines or chronic maternal and/or fetal vascular malperfusion is responsible for HIE with a lowering of the threshold for hypoxic ischemia. The counter argument is that HIE occurs solely as an intrapartum event. Additional investigation is necessary.
期刊介绍:
Fetal and Pediatric Pathology is an established bimonthly international journal that publishes data on diseases of the developing embryo, newborns, children, and adolescents. The journal publishes original and review articles and reportable case reports.
The expanded scope of the journal encompasses molecular basis of genetic disorders; molecular basis of diseases that lead to implantation failures; molecular basis of abnormal placentation; placentology and molecular basis of habitual abortion; intrauterine development and molecular basis of embryonic death; pathogenisis and etiologic factors involved in sudden infant death syndrome; the underlying molecular basis, and pathogenesis of diseases that lead to morbidity and mortality in newborns; prenatal, perinatal, and pediatric diseases and molecular basis of diseases of childhood including solid tumors and tumors of the hematopoietic system; and experimental and molecular pathology.
