| 释义 | placentae plural ofplacentaspecialized Examples of placentaeplacentae When the placentation is dichorionic, separate fetal placental circulations are maintained whether the placentae are fused or separate. The placentae of the experimental gravid monkeys demonstrated diffuse congestion of the intervillous space and coagulation necrosis. Regardless of the appearance of the membrane this is a dichorionic gestation since there are separate placentae on opposing uterine walls. Infarcts were evident in the placentae of dogs with aortic constriction. With distant uterine implantation the two placentae will appear separate and their gross form classified as two discs. An understanding of the relationship of the placentae and fetal membranes is crucial in comprehending chorionicity in twin gestations. The placentae from six of the dogs with elevated thoracic arterial pressure were examined. These lesions were absent in the placentae obtained from five normal pregnant rabbits. Risk factors for abruptio placentae and eclampsia: analysis of 445 consecutively managed women with severe preeclampsia and eclampsia. Through close implantation, the two placentae, as they grow, may fuse to form an apparently single disc. Pathological changes were virtually absent in the kidneys and placentae of the control animals. Placentae were also retained from some litters and extracted as above. Trisomic placentae demonstrate immaturity and hydropic change and it is suggested that the passage of fetal cells across such placentae is made easier as a result of this.
