| Abstract | ||
| Background: Medical professionals refer to vaginal bleeding that occurs during the first twenty weeks of pregnancy—when the fetus is clinically expected to be alive—as a threatened miscarriage. You might or might not feel pain in your abdomen when this bleeding occurs. Nearly half of pregnant women who experience threats of abortion end up losing their babies, and around one-fifth of all pregnant women have indications of such threats in the first trimester. Aim and objectives: During the fourth to eighth week of a pregnancy, when the risk of abortion is at its highest, the spiral artery flow should be monitored and compared to that of healthy pregnancies. Subjects and methods: In this case-control study, 100 pregnant women who were admitted between 2022 and 2024 to the obstetrics and gynecology department of Al-Hussien University Hospital at Al-Azhar University in Cairo, Egypt, participated.. Results: A crucial finding was the significant difference in abortion rates between groups, with 26% in the threatened abortion group compared to 8% in the control group(p=0.031). The Doppler ultrasound findings revealed significantly higher impedance indices in the threatened abortion group. The mean S/D ratio was notably elevated in the threatened abortion group(2.32±0.28) compared to controls(1.95±0.24, p<0.001). Conclusion: Circular artery anomaly Pregnancies with a risk of miscarriage are more likely to end in abortion if certain Doppler indices are elevated, such as the S/D ratio, resistance index (RI), and pulsatility index (PI). The predictive accuracy of these Doppler parameters, particularly the RI with its high sensitivity and specificity, suggests they may serve as valuable early indicators of miscarriage risk. | ||
