Gebelerde hepatik ve portal ven?z sistemin renkli doppler ultrasonografi ile de?erlendirilmesi

摘要

?zet Ama? . ?al??mam?zda normal gebeli?in hepatik ven ak?m paterni, ?ap? ve portal ven ?ap?, ak?m h?z?, volümü ve ak?m y?nü üzerine olan etkilerini; gebe olmayan kontrol grubu ile kar??la?t?rarak gebelik d?neminde geli?en de?i?iklikleri ortaya koymak ama?land?. Y?ntem. 10-40 gebelik haftalar?ndaki toplam 98 gebe ve kontrol grubu olarak do?urganl?k ?a??ndaki gebe olmayan 50 olgu renkli Doppler ultrasonografi (RDUS) tekni?i ile prospektif olarak orta hepatik ve portal venler düzeyinden kan ak?m? incelemesi yap?ld?. Bulgular. ?al??mam?zda gebelik d?neminde hepatik ven ak?m paterninde gebelik periyodu ilerledik?e, normal ak?m paterninden bas?lanm?? paterne do?ru do?rusal bir art?? saptad?k. Portal ven ak?m h?z? de?erinde ve dolay?s? ile volümünde ise gebelik d?nemleri aras?nda istatistiksel olarak ?nemli farkl?l?k izlenmeyip, kontrol grubuna g?re bu parametrelerde art?? geli?ti?ini g?sterdik. Sonu?lar. ?al??mada elde etti?imiz verilerin gebe kad?nlar?n hepatik ve portal ven?z sisteminde gebelikteki fizyolojik yans?maya ba?l? geli?en de?i?ikliklerin RDUS ile de?erlendirilmesinde ?n bir ?al??ma ?zelli?i ta??yaca??n?; buna ba?l? olarak da daha geni? hacimli ?al??malara bir temel olu?turabilece?i kan?s?nday?z.

In our study, effects of normal pregnancy on flow patern and diameter of hepatic vein and diameter, flow velocity, volume and flow direction of portal vein were evaluated and compared with non-pregnant control group in order to explain changes during pregnancy. Methods. A total of 98 women from 10 to 40 weeks pregnancies and 50 non-pregnant women in fertile age as control group were evaluated with color Doppler ultrasound prospectively at the level of middle hepatic and portal veins. Results. We detected linear increase from normal flow pattern to dumped pattern in hepatic vein flow pattern as the pregnancy period progresses. An important difference was not detected in portal vein flow velocity value besides the volumes among the pregnancy periods. We demonstrated an increase in these parameters compared to control group. Conclusion. We suggest that our study carry a preliminary study feature in evaluating color Doppler ultrasound changes in hepatic and portal venous systems due to physiological changes in pregnant women. Consequently, our study will establish a basis for further studies in this area.
