Ultrasound clues may reveal which pregnancies survive threatened miscarriage
NCT ID NCT06797557
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study investigates whether detailed ultrasound measurements can predict if a pregnancy will continue beyond 12 weeks in women experiencing threatened miscarriage. Researchers will use 2D and 3D ultrasound to measure the embryo's size, heart rate, and gestational sac at the initial visit and again after 1-2 weeks. The goal is to identify early signs that indicate a higher chance of the pregnancy continuing, helping doctors and patients make more informed decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify which pregnancies are likely to continue after threatened miscarriage, reducing uncertainty for expectant mothers.
- What could go wrong
- This is an observational study, not a treatment trial. The findings may not apply to all women, and the ultrasound measurements may not reliably predict outcomes in every case.

Inclusion Criteria: * Age 19 -39 years * BMI 18-25 kg/m2 * Singleton pregnancy between 6 to 11 gestational weeks of pregnancy. * First trimester threatened abortion is usually diagnosed in women with history of vaginal bleeding or spotting and/or abdominal pain in whom a live embryo can visualized on scan * Gestational age (GA) calculated by the last menstrual period date (LMP) in women with sure dates and regular menstrual cycles and confirmed by transvaginal sonography performed up to the 11th gestational week, using the crown-rump length Exclusion Criteria: * Uterine malformations or pathology as submucous myoma * Cervical abnormalities as polypi or severe chronic cervicitis * Chronic medical conditions as uncontrolled diabetes or hypertension * Smoking or drug abuse during this pregnancy * Pregnancies resulting from infertility treatments and assisted reproductive techniques. * Women with exogenous progesterone support * Use of abortion induction drugs\\ * First trimester vaginal bleeding or spotting and/or abdominal pain and diagnosed by ultrasound as missed (absence of cardiac activity within fetal pole), incomplete (endometrial thickness between 5 to 15 mm), complete (thin and regular endometrium), anembryonic (gestational sac without a detectable fetal pole) and ectopic (+ve pregnancy test with empty gestational sac
