Abstract

Objectives: Description of ultrasound images of placenta accreta at Hanoi Obstetrics and Gynecology Hospital. Subjects and methods: Retrospective descriptive study of 76 pregnant women diagnosed with placenta accreta and cesarean section scars treated at Hanoi Hospital. Results: Research on 76 pregnant women diagnosed with placenta accreta at Hanoi Obstetrics Hospital. The rate of placenta accreta, increta, percreta are 18.4%; 73.7% and 7.9% respectively. The proportion of pregnant women with ultrasound images showing abnormal lacuna in the placenta, loss of retroplacental “clear zone”, placental bulge, and signs on color doppler are 59.2%,86.8%, 6.6% and 84.2% respectively. Lacunae signs, placental bulge signs and doppler signs appear at an increasing rate with the severity of placenta accreta with a statistically significant difference, p < 0.01. There was a statistically significant difference in the rate of placenta accreta, increta, percreta between the group with 2, 3 or 4 signs or more on ultrasound, compared with the group without 2, 3 or 4 signs or more on ultrasound with p < 0.05. Conclusions: Signs of loss of retroplacental “clear zone”and signs of increased vascularity in color doppler mode are the most common signs in placenta accreta. There is a statistically significant difference when combining 2 ultrasound signs in classifying placenta accreta.
