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

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

About this study

A cross-sectional observational study

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

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

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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

  8. 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

  1. precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental site

    Time frame: (gestational age 28wk- fullterm) till operation

  2. 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

  3. 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

  4. precise diagnosis of uterine dehiscence Using 2d and/or 3d ultrasound doppler to assess: Placental lacunae

    Time frame: (gestational age 28wk- fullterm) till operation

  5. 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

  6. 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

  7. 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

  8. 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
