72 were normotensive and 24 were complicated by hypertension. Of the 24 Comments: The most common routes of infection of placenta, membranes and umbilical cord are ascending infection (from maternal vaginal tract) or 18 Feb 2019 Villitis is a serious maternal health complication that occurs when a placental infection is left untreated. Villitis is characterized by the inflammation Figure 13.1 A term placenta, bread-loafed to show extensive perivillous fibrin deposition, which was histologically found to be associated with VUE. Microscopic We examined placentas where villitis was diagnosed in a previous pregnancy to establish the risk of recurrence and outcome. A total of 304 cases of VUA were Chronic villitis is found in 5-15% of placentae and pregnancies complicated by fetal growth restriction and intrauterine death have an increased incidence, up to 34 villitis and maturation disorders.

Villitis of Unknown Etiology Chronic villitis is a relatively common pathologic finding usually in the third trimester placenta and has two distinct clinical associations: infectious and (apparently) non‐infectious. Additionally, the inflammation may spread to the chorionic villi, which cover the placenta and facilitate the exchange of nutrients and gases between the mother and baby. This is a condition called villitis, which is usually benign but can increase the risk of fetal death. Villitis of Unknown Etiology (VUE) is a type of inflammation of the placental villi, which occurs due to unknown reasons.

This article summarizes the most common pathologic changes in the placenta, devoting the greatest amount of information to the 2020-12-05 Paraffin-embedded placentas from four males with VUE and two males with syphilitic villitis were subjected to fluorescence in situ hybridization (FISH) for the X and Y chromosomes. Villitis was more marked in the placenta of the twin that weighed less and correlated with the degree of weight discordance. On examining the junction between the fused dichorionic placentas, Villitis was studied in placentas from 445 singleton infants from an ethnically homogeneous population with a good socioeconomic standard. There were 161 infants small for gestational age (SGA) and 284 appropriate for gestational age (AGA).

The prevalence of inflammatory villous lesions was determined in a prospective study of 120 consecutive placentas. Cord blood IgM level was measured as an indicator of fetal intrauterine infection, and the birthweights of the infants were noted. Ten cases of villitis were found. Villitis of unknown etiology (VUE) is an important pattern of placental injury occurring predominantly in term placentas. Although overlapping with infectious villitis, its clinical and histologic The placenta is a unique organ, given that it resides at the interface between two human beings – the mother and the fetus. Additionally, it changes throughout gestation in such a dynamic way that identifying the normal histology can be a challenge in and of itself.

VUE is an inflammatory condition involving the chorionic villi (placental villi). VUE is a recurrent condition and can be associated with intrauterine growth restriction (IUGR). Acute Villitis of Placenta is a bacterial infection of the chorionic villi The placenta is an organ that connects the developing fetus to the uterine wall. It is a disc shaped reddish brown structure that connects the fetus to the mother through the umbilical cord.

Villitis of Unknown Etiology (VUE) is a type of inflammation of the placental villi, which occurs due to unknown reasons. In most cases, the inflammation occurs in a term placenta.

Villitis of unknown etiology (VUE) is a diagnosis of exclusion, requiring first that infectious causes be ruled out adequately 1 , 4 - 11 . Introduction: Chronic villitis of unknown etiology (VUE) is a chronic inflammatory lesion of third trimester placenta, which contributes to major adverse obstetric outcomes.
