Villous Stromal Hemorrhage in Placental Villi during Chronic Hypertension

With the purpose of to describe the vessels of the placental villi in hemorrhage condition during chronic hypertension associated to obesity two placentas were analyzed with light microscopy. Stem villi were observed with closed or opened vessels in their trajectory. Numerous intermediate villi were noted with dilated vessels that refill the stromal region. Remarkable changes as picnotic nucleus, nuclear disintegration, thinness and interruption of the syncytium were found. The vessels have exploited in the stromal region. Syncytium very thin surround to numerous erythrocytes. A disorganized structure of the stem villi with frequency can be seen. These villi have a great deal coverture of fibrinoid deposition and others are observed buried by fibrinoid. Chronic hypertension has provoked intravillous hemorrhage in the placental villi which could to put in danger the fetal good development with decreased fetal nutrition
