WebChorionic villus sampling (CVS) is a pregnancy test that checks the baby for genetic or biochemical abnormalities. The placenta is made of the same cells as the baby, so the baby can be tested by taking a small sample of the placenta. The sample is removed using a slender needle inserted through the abdomen. WebConclusions: -Presence of diffuse hypoxic patterns of placental injury adds prognostically negative significance to increased vascularity of chorionic villi. Chorangiosis without those patterns portends minimal risk for the pregnancy, and is associated with significantly fewer pregnancy risk factors, abnormal outcomes, and other placental ...
