INTRODUCTION: Chorangiosis is a proliferation of capillaries in terminal chorionic villi and is considered to be a marker for hypoxia and poor clinical outcome. Not all cases with hypervascular villi meet the generally accepted diagnostic criteria as reported by Altshuler. Our aim was to evaluate cases with villous hypervascularity that do not meet the diagnosis of chorangiosis, in which increased vascularity was present in a significant portion of the villous tissue but was not a diffuse process, which we call focal chorangiosis, to ascertain whether there were clinical or pathologic associations...

Placenta is an organ that is responsible for nourishing and protecting the fetus during pregnancy. Histologic examination of the placenta can yield significant information about pre-uterine and uterine conditions affecting fetal growth. Chorangiosis is defined as the presence of ≥10 terminal villi, each containing ≥10 capillaries per terminal villus in ≥10 low power (×10) fields in at least 3 or more random, non-infarcted cotyledons of the placenta. Chorangiosis is an adaptive response to in-utero hypoxia and its presence signifies better pregnancy outcomes...

INTRODUCTION: Hepatic hemangiomas (HH) are benign vascular tumors, and when large, may contribute to fetal morbidity/mortality. Chorangiosis is placental villus capillary hypervascularity, probably linked with fetal hypoxia. CASE REPORT: We present a macrosomic stillbirth at 39 + 3 weeks of gestation with congestive heart failure (CHF) and myocardial infarction. A giant right hepatic lobe HH was present, along with placental chorangiosis. CONCLUSION: A common pathogenetic pathway between congenital HH and placental chorangiosis has not been reported...

The placenta is a complex organ that influences prenatal growth and development, and through fetal programming impacts postnatal health and well-being lifelong. Little information exists on placental pathology in the presence of congenital heart disease (CHD). Our objective is to characterize the placenta in CHD and investigate for distinctions based on type of malformation present. Placental pathology from singleton neonates prenatally diagnosed and delivered at > 37 weeks gestation was analyzed. Placental findings of absolute weight, placental weight-to-newborn birth weight ratio, chorangiosis, villus maturity, thrombosis, and infarction were recorded and analyzed based on four physiological categories of CHD: (1) single ventricle-aortic obstruction, (2) single ventricle-pulmonic obstruction, (3) two-ventricle anomalies, and (4) transposition of the great arteries (TGA)...

BACKGROUND: The Congenital Human Cytomegalovirus Infection Prevention (CHIP) study, a randomized, blinded, placebo-controlled trial, demonstrated that the efficacy of hyperimmune globulin (HIG) was not different from that of placebo regarding transmission of cytomegalovirus (CMV) from mothers to newborns. Our aim was to analyze histologically HIG effects on placentas collected for the CHIP study. MATERIALS AND METHODS: Virological and histological analyses were performed on 40 placentas from transmitter and nontransmitter HIG-treated and untreated mothers by assessing the number of CMV-positive cells, tissue viral load, tissue damage, and compensatory mechanisms...

AIMS AND OBJECTIVES: Spectrum of hyperglycemia in pregnancy includes gestational diabetes mellitus (GDM), mild hyperglycemia, and overt diabetes. Many authors have worked on morphological changes of the placenta in diabetes, but few studies have correlated histopathological changes with vascular endothelial growth factor (VEGF) immunoexpression. The aim of this study was to detect different histopathological changes in various groups of diabetic placentas and to correlate with VEGF immunoexpression...

We applied qPCR to compare relative telomere length in terminal villi microdissected from term control placentas and placentas of patients suffering from type 1 diabetes. Significant differences were not found in the relative T/S ratios between placental groups or between the diabetic placentas affected and those not affected with chorangiosis. We hypothesize that there is no relationship between decreased placental proliferative ability in maternal diabetes type 1 and telomere shortening.

We describe a patient with Class C diabetes who presented for nonstress testing at 36 weeks and 4 days of gestation with nonreassuring fetal heart tones (NRFHT) and oligohydramnios. Upon delivery, thrombosis of the umbilical cord was grossly noted. Pathological analysis of the placenta revealed chorangiosis, vascular congestion, and 40% occlusion of the umbilical vein. Chorangiosis is a vascular change of the placenta that involves the terminal chorionic villi. It has been proposed to result from longstanding, low-grade hypoxia in the placental tissue and has been associated with such conditions such as diabetes, intrauterine growth restriction (IUGR), and hypertensive conditions in pregnancy...

We describe the third case world-wide of a chorangiocarcinoma, a tumour with an abnormal trophoblast proliferation in combination with a hypervascular chorangiosis of the villous stroma. The lesion was an incidential finding by a healthy 31-year-old woman, gravida 1, para 1 when the pregnancy was terminated at 34 weeks gestation because of fetal distress and intrauterine growth restriction. Hormonal levels were within the normal range. Mother and infant had an uneventful postpartum course. Immunohistochemical studies of the abnormal trophoblasts demonstrated strong immunoreactivity for HCG and in 80% for Ki 67...

Objectives  Current guidelines for diagnosis and management of early-onset intrauterine growth restriction (IUGR) rely on umbilical artery Doppler (UAD), without including uterine artery Doppler (UtAD). We hypothesized that IUGR cases with abnormal UAD but normal UtAD has a different spectrum of placental pathology compared with those with abnormal UtAD. Study Design  Retrospective review of pregnancies with sonographic evidence of IUGR and abnormal UAD prior to delivery. Cases with ≥ 1 UtAD record(s) after 18+0 weeks' gestation and placental pathology were included...

CONTEXT: -Chorangiosis has been regarded as a result of low-grade placental hypoxia associated with pregnancy risk factors and abnormal outcomes. It is unknown whether these are a consequence of chorangiosis itself or of associated other placental pathology. OBJECTIVE: -To prove that chorangiosis itself does not portend an increased risk for pregnancy unless associated with other placental pathology. DESIGN: -This retrospective statistical study analyzes 1231 consecutive placentas with diffuse or focal hypervascularity of chorionic villi: 328 with preuterine pattern of chronic hypoxic placental injury (group 1), 297 with uterine type of chronic hypoxic placental injury (group 2), and 606 cases with chorangiosis (group 3) not fulfilling the inclusion criteria for groups 1 or 2...

Intrauterine passage of meconium is common, occurring in approximately 10-15% of term births. Uncommonly, long-standing meconium exposure is associated with umbilical vascular myonecrosis, but few studies have evaluated specific clinical and pathologic features. This is a retrospective study of 481 term placentas: 139 with meconium-associated myonecrosis, 139 with meconium in fetal membranes, only 62 with meconium in the cord without myonecrosis, and 139 controls without meconium. We studied clinical factors, including clinical evidence of meconium discharge, fetal distress, APGAR scores, intrauterine growth restriction (IUGR), and intrauterine fetal demise (IUFD), and histologic factors, including acute chorioamnionitis, umbilical cord complications, uteroplacental malperfusion, fetal thrombosis, chorangiosis, and fetal nucleated red blood cells...

INTRODUCTION: During a pregnancy complicated by diabetes, the placenta undergoes a number of functional and structural pathologic changes. However, differences across studies may reflect pathophysiologic differences of diabetes types under investigation. METHODS: We examined placental pathology from women ages 18-40 years with self-identified race/ethnicity; singleton, live births; and type 1 (T1DM; n = 36), type 2 (T2DM; n = 37), or gestational diabetes mellitus (GDM; n = 126)...

Nowadays, the continuous rise of maternal obesity is followed by increased gestational diabetes mellitus incidence. GDM is associated with adverse fetal and neonatal outcome that often presents with macrosomia, birth trauma, neonatal hypoglycemia, and respiratory distress syndrome. Inclusion of GDM into 'the great obstetrical syndromes' emphasizes the role of the placenta in interactions of the maternal and fetal unit. The placenta acts as a natural selective barrier between maternal and fetal blood circulations...

AIM: This retrospective analysis is aimed to study clinical and placental associations of placental acute, chronic, and acute-on-chronic (overlap) hypoxic lesions. MATERIAL AND METHODS: Frequencies of 32 clinical (maternal and fetal) and 47 placental (gross and microscopic) phenotypes were compared by the Yates χ(2) with the Holm-Bonferroni correction among consecutive placentas from 2831 ≥ 16-week gestations: 778 placentas with chronic hypoxic lesion(s) (diffuse patterns of hypoxic placental injury, chorangiosis, excessive extravillous trophoblasts, microscopic chorionic pseudocysts, clusters of decidual multinucleate trophoblasts), 481 placentas with acute hypoxic lesion(s) (infarction, intravillous hemorrhage, deep meconium penetration, membrane laminar necrosis), 585 placentas with hypoxic overlap lesion(s) (coexisting at least one lesion from each of the above groups), and 987 placentas without placental hypoxic lesions, adjusted for gestational age...

The vascularity of placental tissue is dependent on various factors of which fetomaternal hypoxia plays a major role. Hypoxia can be of different types and each type influences the vascularity of the villi, especially terminal villi, in its own way. In this study, we attempted to identify villous vascular changes in a group of term placentae from mothers with diseases complicating pregnancy. Chorangiosis was the most frequently identified lesion while chorangioma was found in only 2 cases. There were no cases of chorangiomatosis...
