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. Conclusion: The clinically oriented, unifying and simple placental pathology classification system may work as a platform for Morphological characteristics of Placenta in various conditions . finding was villitis basalis, which was noted in 7 placentas with high grade VUE and 4.

Not surprisingly, little is known about placental ﬁndings in such cases, with only 1 report of 3 cases in the world Villitis of unknown etiology (VUE) is a common lesion affecting placenta mostly during the third trimester on microscopic examination, whatever the pregnancy outcomes is. The cellular composition of the inflammatory infiltrate is defined by lymphocytes and macrophages, and VUE is thought to be the result of an immunological materno-fetal conflict.

Quick Summary: Villitis of Unknown Etiology (VUE) is a type of inflammation of the placental villi, which occurs due to unknown reasons.

doi: 10.1067/s0002-9378(03)00577-5. 2021-02-24 Placentas with villitis were found to express MHC class II antigens. However, some showed no immunoreactivity. Occasional villi unaffected by villitis, including those near placental infarcts, also expressed MHC class II antigens. The study therefore showed that immunohistochemistry cannot be used to define villitis of unknown aetiology. Placental chronic villitis was observed in 44 cases (2.12%) of 2,073 histologically examined placentas. Infiltrating lymphocytes in chronic villitis were determined by immunohistochemistry to be predominantly helper/inducer T cells.

2007-10-01 · 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.
