Abstract
Placenta previa is a severe complication of pregnancy and is the most common cause of postpartum hemorrhage, which often endangers the lives of pregnant women. In patients with malignant placenta previa and placenta accreta, ultrasound can display obvious blood flow changes, such as abnormal blood flow in the placental cavity, abundant blood flow signals, placenta accreta, a thinned echo zone between the uterus and placenta, an enlarged cervix, and thinned myometrium. Color Doppler ultrasound can accurately identify whether it is complete placenta previa. This study was conducted to assess the role of Doppler ultrasound in the diagnosis of invasion of the placental tissue. The study was a retrospective descriptive study conducted at Aljala Maternity Hospital in Tripoli during the years 2020-2021. Among 120 pregnant women were selected from medical files, and a predesigned questionnaire was formed to collect data from patients by simple random sampling methods. The data was coded and analyzed by using SPSS (Statistical Package for the Social Sciences) version 20. All variable results were considered statistically significant with a P value less than 0.05. Among 120 pregnant women who were diagnosed with placental invasion, the mean age group was 29.45 ± 5.345 SD, the minimum age was 18 years, and the maximum age was 45 years. Regarding the obstetric history, the mean gravidity was 3.37 ± 1.942 SD, the mean parity was 1.76 ± 1.559 SD, the mean miscarriage rate was 1.71 ± 0.454 SD, and the mean gestational age at time of diagnosis was 6.21 ± 2.111 SD. Regarding the prior experience with abnormal placentation in previous pregnancy, 66.3% had experienced it. Regarding the Doppler ultrasound approach, 73% of patients had abnormal Doppler findings on assessment. Regarding the prevalence of complications among participants who were diagnosed with placental invasion and the most commonly recognized complications were wound infection and thromboembolism, which both account for 63.5%. On assessing the placental invasion by Doppler ultrasound, this approach had a significant impact on evaluating pregnancy. Therefore, early utilization of Doppler is recommended, particularly in high-risk groups, to evaluate and detect serious health outcomes related to placental invasion.
