# Ultrasound Model to Help Differentiate Between Placenta Accreta Spectrum and Uterine Dehiscence in 3rd Trimester Pregnancies

**Official Title:** Placenta Accreta Spectrum VS Uterine Scar Dehiscence: Accurate Ultrasound Model in 3rd Trimester Pregnancies for Percise Diagnosis

**NCT ID:** [NCT07236060](https://clinicaltrials.gov/study/NCT07236060)

## Key Facts

- **Status:** NOT_YET_RECRUITING
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 50
- **Lead Sponsor:** Assiut University
- **Conditions:** Placenta Accreta, Third Trimester, Uterine Scar Dehiscence
- **Start Date:** 2025-11-15
- **Completion Date:** 2026-12-15
- **CT.gov Last Update:** 2025-11-19

## Brief Summary

By using 2d Ultrasound on 3rd trimester pregnant women, a model is made to help differentiate between placenta accreta spectrum and uterine scar dehiscence before operative action to help prepare multi-disciplinary steps if needed

## Detailed Description

A cross-sectional observational study

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 50 Years
- **Sex:** FEMALE
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Women in 3rd trimester pregnancy with low lying placenta previa
* History of 1 or more C-section
* Patients planning to deliver baby in Assiut women health hospital
* Willing and able to participate

Exclusion Criteria:

* Antepartum Hemorrhage(sever attack) as it hinders time for accurate diagnosis and calling expert team of diagnosis
```

## Interventions

- **2D ultrasound doppler** (DEVICE) — using 2d ultrasound doppler to form a model that will help distinguish between placenta accreta spectrum and uterine scar dehiscence pre-operatively

## Primary Outcomes

- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: Placental site** _(time frame: (gestational age 28wk-full term) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: placental thickness** _(time frame: (gestational age 28wk- full term) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: placental size** _(time frame: (gestational age 28wk- fullterm) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: placental lacunae** _(time frame: (gestational age 28wk-full term) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: Loss of placental hypoechoic zone** _(time frame: (gestattional age 28wk-full term) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: Mean systolic velocity in both uterine arteries** _(time frame: (gestational age 28wks-full term) till time of operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: Peak systolic velocity in uteroplacental interface** _(time frame: (gestational age 28wks- full term) till operation)_
- **Model for percise diagnosis of placenta accreta spectrum Using 2d and/or 3d ultrasound doppler to assess: Peak systolic velocity in uterovesical interface** _(time frame: (gestational age 28wks- full term) ill operation)_

## Secondary Outcomes

- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental site** _(time frame: (gestational age 28wk- fullterm) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental size** _(time frame: (gestational age 28wk- full term)till the operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental thickness** _(time frame: (gestational age 28wk-full term) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental lacunae** _(time frame: (gestational age 28wk- fullterm) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Loss of placental hypoechoic zone** _(time frame: (gestational age 28wks - fullterm) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Mean systolic velocity in both uterine arteries** _(time frame: (gestational age 28wk- fullterm) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Peak systolic velocity in uteroplacental interface** _(time frame: (gestational age 28wk- fullterm) till operation)_
- **precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Peak systolic velocity in uterovesical interface** _(time frame: (gestational age 28wk-full term) till operation)_
