Abstract Objective: Delayed villous maturation (DVM) is a spectrum of placental disease characterised by decreased tertiary villus formation, reduced vasculosyncytial membrane formation and, in the more severe grades, increased large bullous villi. In some series it is associated with an increased risk of stillbirth in the late third trimester, but overall there is little data on its significance. The aim of this study was to assess perinatal factors associated with, and the clinical significance of, the finding of DVM on placental histology. Methods: This was a retrospective study investigating all pregnancies with DVM diagnosed on placental histology in a tertiary level unit from December 2001 to August 2006. Over 6 years 2,915 placentas were triaged for histopathological assessment, representing 6.1% of all 48,054 deliveries in this time period. One hundred and ninety (6.3%) of these selected cases showed DVM. Fifteen placentas less than 34 completed weeks gestation were excluded, leaving 175 for further analysis. Principal Results: When compared with controls matched for gestation and delivering within the same time period (n=175), DVM was significantly associated with pre-gestational diabetes (8% vs 2.8%, p<0.05; RR 2.8 (95% CI 1.03-7.6)), gestational diabetes (8.6% vs 3.4%, p<0.05; RR 2.5 95% CI 0.99-6.3), and antenatal or intrapartum intrauterine death (8.6% vs 0%, p<0.05).Conclusion: DVM is associated with both gestational and pre-gestational diabetes mellitus and with perinatal death.
