Ultrasound Monitoring of Fetuses With Vascular Intra-uterine Growth Restriction (IUGR) Using the Isthmus Systolic Index (ISI): Feasibility, Comparison to Normal Fetuses and Association With Perinatal Mortality
France320 participantsStarted 2016-09
Plain-language summary
Fetuses with IUGR, there is a correlation between Doppler indices of cardiovascular function and perinatal mortality. An index of systolic flow velocities at the aortic isthmus (ISI) has previously been described in a population of normal fetuses. Fetuses with IUGR, the velocities recorded in the aortic isthmus could be affected and the normal development of the ISI should be changed, because of the increase in placental resistance on one hand, and the gradual deterioration ventricular functions on the other one. Investigators hypothesize that the ISI index in the context of placental insufficiency could provide additional arguments on the extraction timing, the prognosis and the fetal extraction mode to severe hypoxia. The primary outcome of the study is to evaluate in an exploratory manner the feasibility and the potential interest of longitudinal monitoring of fetuses with IUGR by Doppler systolic isthmus and the calculation of the ISI index.

* OR a confirmation of placental vascular disease by histological examination
* CONTROL group: non IUGR fetuses for gestational age (normal for weight, Doppler, and structural analyse)
Exclusion Criteria:
* Twin or multiple pregnancy,

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
