Placental fetal vascular malperfusion in maternal diabetes mellitus

With the double immunostaining, FVM is as common as maternal vascular malperfusion pattern of placental injury in diabetic pregnancies with high prevalence of fetal congenital malformations. This is likely due to umbilical cord compression evoked by mass-forming fetal anomalies. Recognizing placental FVM may sensitize to the increased risk of neonatal systemic thrombotic pathology. However, several hypoxic lesions and patterns as well as those of shallow placental implantation were also seen with increased frequencies in diabetic pregnancies.
