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. The umbilical cord contains two umbilical arteries and one umbilical vein Placenta - Villitis of unknown etiology (VUE) See Elsevier's new video about their Clinic Review Articles on our homepage or click here. 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 characteristics are distinct. It is a common lesion, affecting 5% to 15% of all placentas.

Villitis placenta

28 clinical and 47 placental phenotypes were compared between the two groups by Yates 2 … Placental involvement by CMV infection has been typically made by histological diagnosis of focal segmental lymphoplasmacytic villitis [28, 29], with additional histological features as described above and depicted in Fig. 1, and confirmed by positive immunohistochemistry or in situ hybridization on placental tissue [4, 5, 6, 17] (Figs. 1 and 2). 2020-06-01 2017-01-01 Placental villitis, which is defined by the presence of lymphocytic or macrophagic inflammatory cells within the villosities, constitutes a recently-described histopathological entity. This condition is the consequence of an immune response of the feto-placental unit towards a non-specific, multiple aggression and the incidence is very low. 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. Villitis of unknown etiology (VUE) is a diagnosis of exclusion, requiring first that infectious causes be ruled out adequately 1 , 4 - 11 . Villitis of unknown etiology (VUE) is an important pattern of placental injury occurring predominantly in term placentas.

After exclusion of multiple pregnancies, infectious and TOP without IUGR, 178 placentas were considered eligible. The overall prevalence of lesions was estimated as 4.3% of placentas analyzed. VUE is also characterised by the transfer of maternal lymphocytes across the placenta. VUE is diagnosed in 7–10% placentas in pregnancies. Roughly 80% of the VUE cases are in term placentas (greater than 37 weeks of pregnancy). A case of VUE in a placenta less than 32 weeks old should be screened for infectious villitis. The placentas of patients with influenza infection were examined for histologic signs of chronic villitis.

This lesion was also the predominant villitis in the In our study, villitis, independent of the extent, was clearly overrepresented in stillbirth placentas (18.3% compared to 5.1% in controls) and villitis (<1% or ≥1%) had approximately a four-fold risk for stillbirth in term pregnancies. 2016-08-01 · About 281 placentas presented lesions of villitis or intervillositis. No lesions were found on products of early abortion. After exclusion of multiple pregnancies, infectious and TOP without IUGR, 178 placentas were considered eligible. The overall prevalence of lesions was estimated as 4.3% of placentas analyzed.

Even if the classic intranuclear and intracytoplasmic inclusions are not seen, an immunohistochemical study for CMV can be beneficial, as it will highlight infected cells and eosinophilic debris within the villi. 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. Villitis of unknown eti-ology (VUE) is a diagnosis of exclusion, requiring ﬁrst that infectious causes be ruled out adequately 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 2021-02-24 · Villitis of unknown etiology (VUE) is an important pattern of placental injury occurring predominantly in term placentas.
