The Relationship Between Doppler Parameters and Perinatal Outcomes in Postterm Pregnancies

Amaç: Uzamış gebeliklerde doppler ultrasonografi bulguları ile perinatal sonuçlar arasındaki ilişkiyi incelemek amaçlandı. Gereç ve Yöntem: Bu çalışmaya 37-41 gebelik haftası arasındaki 51 (kontrol grubu), ≥41 gebelik haftasındaki 50 hasta (çalışma grubu) dahil edildi. Renkli doppler ultrasonografide umblikal arter ve orta serebral artere ait akım paternleri değerlendirilerek doppler indeksleri ölçüldü. Bu damarlarda akımı değerlendirmek için, pulsatilite indeksi, rezistivite indeksi ve sistol/diastol oranı ölçüldü. Bulgular: Uzamış gebeliklerde, kontrol grubuna göre, umblikal arter rezistivite indeks değeri daha yüksek, pulsatilite indeks değeri daha düşük bulundu. Uzamış gebeliklerde ölçülen orta serebral arter rezistivite indeks ortanca değeri kontrol grubuna göre anlamlı derecede daha düşüktü ve bu, beyin için oluşturulan koruma mekanizması lehine bir bulgu olarak değerlendirildi. Orta serebral arter rezistivite indeks / umblikal arter rezistivite indeks ortanca değeri çalışma grubunda (1.11) kontrol grubununkine (1.25) göre istatistiksel olarak daha küçüktü, nitekim uzamış gebelikler için kötü perinatal sonuç %64 sıklıkla kontrol grubuna göre istatistiksel olarak anlamlı derecede daha fazla bulundu. Uzamış gebeliklerde kötü perinatal sonucu öngörmede orta serebral arter rezistivite indeks / umblikal arter rezistivite indeks oranı

Uzamış Gebeliklerde Doppler Ultrasonografi Bulguları ile Perinatal Sonuçlar Arasındaki İlişki

Aim: The aim of the study is to identify the relationship between doppler parameters and perinatal outcomes in post-term pregnancies. Material and Method: 101 pregnant women (37-41 weeks, control group; n:51 and ≥41 weeks, study group, n:50) were included in the study. We performed umblical artery and middle cerebral artery blood flow velocity waveform (pulsatility index, resistivity index, and systole/diastole ratio) analyses for our patients. Results: The mean value of the umbilical artery resistivity index was significantly higher in the study group than the control group while the mean value of the umbilical artery pulsatility index was significantly lower in the study group. The middle cerebral artery resistivity index was significantly lower in the study group, which was consistent with preferantial perfusion of the brain. We also found decreased ratios of middle cerebral artery resistivity index in umblical artery resistivity index in the study group (1.11) compared with the control group (1.25). These findings can be interpreted in favor of worse perinatal outcomes in the study group while the increased adverse perinatal outcome rates (%64) in the study group supports this view. The ratio of middle cerebral artery resistivity index to umblical artery resistivity index
