Study summary

This study aims to evaluate possible predictors for the successful od external cephalic version (ECV), a procedure that is indicated in your case due to breech presentation of your baby and your desire to avoid cesarean section. Before the procedure, a detailed ultrasound scan will be performed to measure several parameters. After the procedure we will collect data about the duration, outcome and eventual complications of ECV.

Read the detailed description

Pregnant women with a diagnosis of fetal breech presentation, desirous of an attempt of ECV after counseling and written consent and hospitalized for the procedure will be consecutively enrolled. The following anonymous data will be recorded:

  • Demographic and anthropometric data (i.e., age (y), ethnicity, height (m), weight (kg), BMI);
  • Parity
  • Gestational Age (weeks + days)

Before ECV attempt, the following evaluations will be performed:

  • Vaginal examination to evaluate the cervical dilatation and the level of presenting part (floating or not floating)
  • Fetal transvaginal ultrasound reporting:

    • biometry (BPD, HC, AC, FL, EFW);
    • Occiput position (right, left);
    • Back position (anterior, posterior, right, left);
    • Breech variant (footling, frank, complete);
    • Fetal leg posture (extended, flexed)
    • Placental localization;
    • Amniotic Fluid Index (AFI);
    • Fore-bag of amniotic fluid;
    • Eventual presence of nuchal cords;
    • Fetal head ballottement (yes, no);
    • Occiput-spine angle (see Figure 1)

Then, all the participants will undergo a transabdominal ultrasound-guided ECV in a semi-sitting position by the same expert operator (B.C.). After the procedure, the following data will be collected:

  • Success (yes, no)
  • Duration of the procedure (min);
  • Direction of fetal flip in case of success (frontside flip, backside flip)
  • Pain perception in Numerical Rating Scale (NRS) (1-10);
  • Reason for terminating the procedure (success, failure, pain, uterine contractions, non-reassuring fetal conditions)

Study population

We will consecutively enroll all pregnant women at the term of gestation with a fetal breech presentation undergoing ECV attempt after counseling at Fondazione Policlinico Universitario Agostino Gemelli IRCCS of Rome, satisfying the inclusion criteria.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 y.o.;
  • Pregnant women with a diagnosis of fetal breech presentation eligible and desirous for ECV;
  • Singleton;
  • At term (≥ 37 weeks);
  • Breech presentation;
  • No previous uterine scars or other indications for elective C-section;
  • Signed written to study participation.

Exclusion criteria

Exclusion Criteria:

  • Age \<18 y.o.;
  • Preterm gestational age;
  • Multiple pregnancies;
  • Indications for elective cesarean section;
  • Incomplete obstetrical data;
  • Refusal to provide .
  • Desire to an elective C-Section
  • Controindications for ECV or vaginal delivery (placental abruption, placenta previa, uterine malformations)
  • Reduction of amniotic fluid (AFI \<4 cm)
  • Uterine contractions
  • Vaginal bleeding
  • Premature rupture of membranes
  • Nonreassuring fetal heart rate patterns before the procedure.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Group ECV

    Pregnant women with a fetus in breech presentation at term of pregnancy undergoing an external cephalic version (ECV) maneuver. This procedure is aimed to induce fetal cephalic position allowing vaginal delivery instead of cesarean section

    Procedure: ultrasound

Interventions

  • Procedureultrasound

    before ECV procedure, an ultrasound will be performed to evaluate * fetal biometry (BPD, HC, AC, FL, EFW); * Occiput position (right, left); * Back position (anterior, posterior, right, left); * Breech variant (footling, frank, complete); * Fetal leg posture (extended, flexed) * Placental localization; * Amniotic Fluid Index (AFI); * Fore-bag of amniotic fluid; * Eventual presence of nuchal cords; * Fetal head ballottement (yes, no); * Occiput-spine angle These parameters will be compared to find predictive factors for successful ECV

What researchers measure

Primary outcomes

  1. To evaluate ECV success rate.

    to evaluate clinical and ultrasound parameters possibly predictive of the success of ECV. This will allow the creation of a predictive model for adequate counseling for the women undergoing the procedure for the cephalic version of fetuses in breech presentation at term of pregnancy

    Time frame: during the procedure

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
