The relation of pulsatility indices of middle cerebral, umbilical and uterine arteries with birth weight in normal pregnancies

Abstract Aim. The aim of this study was to assess the relation between middle cerebral to umbilical artery pulsatility index ratio and uterine artery pulsatility and resistive indices with birth weights in normal pregnancies. Methods. The pulsatility indices were obtained together with the birth weight from 160 healthy pregnancies. Measurements were done at five weeks intervals from 20 weeks’ gestation until delivery. A relationship between indices and birth weight was sought at gestational age ranges of 20 th to 40th weeks. Results. The values of pulsatility indices towards to 40th weeks of gestation were decreased progressively. There was a correlation between the pulsatility indices of uterine and the middle cerebral arteries nd the birth weights of cases. Conclusion. Doppler pulsatility index measurements can be valuable in detecting birth weight. Keywords: Pulsatility index, middle cerebral artery, umbilical artery, uterine artery, birth weight Ozet Amac . Bu calismanin amaci normal gebelerde orta serebral arter- umbilikal arter pulsatilite indeksi orani ve uterin arter pulsatilite ve rezistif indekslerinin dogum agirliklari ile iliskisini degerlendirmektir. Yontem. Yuzaltmis saglikli gebeden pulsatilite indeksleri ile birlikte dogum agirliklari elde edildi. Olcumler 20. haftadan itibaren doguma kadar beser hafta araliklarla yapildi. 20-40. gebelik haftalarindaki indeksler ve dogum agirligi arasindaki iliski arastirildi. Bulgular. Gebeligin 40. haftasina dogru pulsatilite indekslerinin degerleri giderek azaldi. Uterus ve orta serebral arterlerin pulsatilite indeksleri ve olgularin dogum agirliklari arasinda bir korelasyon vardi. Sonuc. Doppler pulsatilite indeksleri olcumu dogum agirligini saptamada degerli olabilir. Anahtar sozcukler: Pulsatilite indeksi, orta serebral arter, umblikal arter, uterin arter, dogum agirligi
