Abstract

Purpose To assess the longitudinal variation of the ratio of umbilical and cerebral artery pulsatility index (UCR) in late preterm fetal growth restriction (FGR).

Materials and Methods A prospective European multicenter observational study included women with a singleton pregnancy, 32+ 0–36+ 6, at risk of FGR (estimated fetal weight [EFW] or abdominal circumference [AC] < 10th percentile, abnormal arterial Doppler or fall in AC from 20-week scan of > 40 percentile points). The primary outcome was a composite of abnormal condition at birth or major neonatal morbidity. UCR was categorized as normal (< 0.9) or abnormal (≥ 0.9). UCR was assessed by gestational age at measurement interval to delivery, and by individual linear regression coefficient in women with two or more measurements.

Results 856 women had 2770 measurements; 696 (81 %) had more than one measurement (median 3 (IQR 2–4). At inclusion, 63 (7 %) a UCR ≥ 0.9. These delivered earlier and had a lower birth weight and higher incidence of adverse outcome (30 % vs. 9 %, relative risk 3.2; 95 %CI 2.1–5.0) than women with a normal UCR at inclusion. Repeated measurements after an abnormal UCR at inclusion were abnormal again in 67 % (95 %CI 55–80), but after a normal UCR the chance of finding an abnormal UCR was 6 % (95 %CI 5–7 %). The risk of composite adverse outcome was similar using the first or subsequent UCR values.

Conclusion An abnormal UCR is likely to be abnormal again at a later measurement, while after a normal UCR the chance of an abnormal UCR is 5–7 % when repeated weekly. Repeated measurements do not predict outcome better than the first measurement, most likely due to the most compromised fetuses being delivered after an abnormal UCR.

Zusammenfassung

Ziel Beurteilung der longitudinalen Variation der umbilikozerebralen Ratio (UCR) der Pulsatilitätsindizes bei später fetaler Wachstumsrestriktion (FGR).

Material und Methoden Eine prospektive europäische multizentrische Beobachtungsstudie schloss Frauen mit Einlingsschwangerschaft (32+ 0–36+ 6) und Risiko für FGR ein (geschätztes fetales Gewicht (EFW) oder Abdomenumfang (AU) < 10. Perzentile, abnormaler arterieller Doppler oder Absinken der AU-Perzentile um > 40 Punkte im US in der 20. SSW). Der primäre Outcome war kombiniert aus auffälligen Geburtsparametern oder schwerer neonataler Morbidität. Die UCR wurde als normal (< 0,9) oder abnormal (≥ 0,9) eingestuft. Die UCR wurde im Messintervall bis zur Entbindung mittels SSW und mittels individuellen linearen Regressionskoeffizienten bei Frauen mit 2 oder mehr Messungen bewertet.

Ergebnisse 856 Frauen hatten 2770 Messungen; 696 (81 %) hatten mehr als eine Messung (Median 3, IQR 2–4). Bei Einschluss hatten 63 (7 %) eine UCR ≥ 0,9. Diese entbanden früher und hatten ein niedrigeres Geburtsgewicht und eine höhere Inzidenz für einen unerwünschten Outcome (30 % vs. 9 %, relatives Risiko 3,2; 95 %-KI 2,1–5,0) im Vergleich zu Frauen mit normaler UCR bei Einschluss. Wiederholte Messungen nach abnormaler UCR bei Einschluss waren in 67 % (95 %-KI 55–80) erneut abnormal, aber nach einer normalen UCR betrug die Wahrscheinlichkeit, eine abnormale UCR zu finden, 6 % (95 %-KI 5–7 %). Das Risiko für einen kombinierten unerwünschten Outcome war ähnlich, wenn man den ersten oder den nachfolgenden UCR-Wert verwendete.

Schlussfolgerung Eine abnormale UCR ist wahrscheinlich bei einer späteren Messung wieder abnormal, während nach einer normalen UCR die Wahrscheinlichkeit einer abnormalen UCR bei wöchentlicher Wiederholung 5–7 % beträgt. Wiederholte Messungen sagen das Ergebnis nicht besser voraus als die erste Messung, was höchstwahrscheinlich darauf zurückzuführen ist, dass die am stärksten gefährdeten Föten nach einer abnormalen UCR entbunden werden.
