Of 387 stillborn fetuses, 327 (84.5%) had maternal vascular PPLs and 60
(15.6%) had abnormal CNVs. Maternal vascular PPLs were more common in
stillborn fetuses with abnormal CNVs compared with those with normal
CNVs (81.7% vs. 64.2%; p=0.008). The proportions of fetal vascular,
maternal/fetal inflammatory, and immune/idiopathic PPLs were similar
among stillborn fetuses with abnormal CNVs compared to those with normal
CNVs. Pathogenic CNVs in stillborn fetuses with maternal vascular PPLs
spanned several known genes.
