Outcome Measures

Primary Outcomes (1)

  • The measurement of signal strength

    The measurement of signal strength (in arbitrary units) in the Inter-Villi Space in the first trimester (at 8SA, 11SA and 13SA) obtained by contrast ultrasound, in women who have confirmed a voluntary termination of pregnancy.

    1 day

Secondary Outcomes (4)

  • Measurement of the vascularization parameters of the Inter-Villi Space (IVS) and myometrium: signal strength

    1 day

  • Measurement of the vascularization parameters of the Inter-Villi Space (IVS) and myometrium: infusion kinetics.

    1 day

  • Comparison of quantitative data on uteroplacental vascularization obtained with the 2 techniques.

    1 day

  • Obtaining analyzable placental villi for the study of the development and functions of the human placenta.

    1 day

Study Arms (1)

surgical termination of pregnancy

EXPERIMENTAL

Contrast agent: SonoVue®: Hexafluoride (SonoVue®, injectable solution to solubilisate, 8µg/mL) is injected in all patients for ultrasound angiography during the termination of pregnancy. 2,4 mL are administrated per patient, divided into two injections of 1,2 mL.

Drug: Contrast agent: SonoVue®.

Interventions

SonoVue® Injection: will be done through the peripheral venous way already set up by the anesthetist for its injection. None venous dedicated way will be established. The injection will take place when the woman will be under general anesthesia, ventilated and under constant cardio-respiratory monitoring.

Also known as: hexafluoride
surgical termination of pregnancy
