Abruptio placenta: sonographic and pathologic correlation

Is pathologic confirmation of placental abruption more reliable in cases due to chronic etiologies compared with acute etiologies?

“…Walker et al [7] described a case where a chronic abruption was diagnosed in a woman with preeclampsia by ultrasound performed for routine fetal monitoring. However, in the absence of retained hematoma, the sonographic diagnosis may not be possible [3], although newer technology, particularly the availability of magnetic resonance imaging [2], has improved diagnostic accuracy.…”

Intrauterine Haematoma an Ultrasonic Study of Threatened Abortion

“…THREATENED abortion is defined as vaginal bleeding alone or associated with lower abdominal pain in a pregnancy of less than 20 weeks (Wilson and Carrington, 1979). Later in pregnancy bleeding and pain lead to a diagnosis of accidental haemorrhage from the placental site.…”

Intrauterine membranes: Sonographic findings and clinical significance

“…Extrachorionic hemorrhage elevates the chorionic membranes, producing a fine linear echo that appears to be lying or floating within the uterine cavity, separated from the uterine wall by an echolucent space. 8 The retrochorionic space may contain a solid clot; but if it does not, the membrane has a similar appearance to that seen in CAS. The findings that distinguish the two conditions are extension of the lucent space under the margin of the placenta in extrachorionic hemorrhage and extension of the membrane over the fetal surface of the placenta in CAS.…”
