2023年8月11日 · Massive perivillous fibrin deposition is placental lesion characterized by extensive massive deposits of fibrin in the intervillous space. MPVFD is associated with recurrent miscarriage, intra uterine fetal death (IUFD), intra uterine growth restriction (IUGR) and …
Massive perivillous fibrin deposition / maternal floor infarction
2024年6月19日 · Massive perivillous fibrin deposition (MPFD) involves extensive and smothering deposition of fibrin / fibrinoid material around chorionic villi within the placental parenchyma (maternal space), including at least 25% of intraparenchymal or basal villi
Perivillos fibrin deposition was without deleterious effect on the well-being of the fetus, and babies in whose placentas this lesion was present had an unduly low incidence of neonatal asphyxia. Perivillous fibrin deposition was unrelated to fetal arterial disease or villous syncytial degeneration. It is concluded that.
Perivillous fibrin deposition - ULTRASOUNDPAEDIA
Perivillous fibrin deposition is present in approximately 20% of term placentae. It occurs less frequently in placentas after premature delivery (6%) and in the placentas of diabetic (6%) and pre-eclamptic (12%) women.
[Massive subchorionic fibrin deposit: echographic diagnosis]
If the deposition is massive, as in the two cases reported here, delayed fetal growth may occur due to altered placental function. Diagnosis using ultrasound is useful both to identify fibrin plaques and to identify possible fetal hypo-development.
