Background: Hemodynamic changes in liver vascular structures of patients in the pediatric age group are evaluated by doppler ultrasonography.
Material: Fifty- nine hepatosteatosis patients, classified as mild, moderate or severe, and 23 healthy volunteers were included in this 82-person study. The height, weight, liver size tests of the subjects were measured. Those values were compared in the patient and control groups. In the patient and control groups, color duplex Doppler ultrasonography was used to examine portal vein peak velocity, portal vein flow volume, hepatic artery resistive index (RI), hepatic artery pulsatility index (PI) and hepatic artery flow volume.
Results: Similar to the degree of hepatosteatosis, increases in body mass index, liver size were statistically significant (p<0.05). The difference between portal vein peak velocity hepatosteatosis and control groups was found statistically significant. As the hepatosteatosis grade increased, there was no statistically significant decrease in hepatic arterial flow volume, portal vein flow volume, and total flow volume. Hepatic artery RI and PI values ​​were statistically significantly lower in the control group than the other groups (p <0.05). There was a significant mild decrease in the mild stool group compared to the middle steat group. Although the hepatic artery RI and PI values ​​did not differ statistically in the comparison of the hepatosteatosis group, there was a minimal increase in the RI and PI values ​​as the steatosis grade increased.
Discussion: According to these results, as the level of steatosis increases, the changes in the portal venous structures become more prominent and the resistance increases in vascular structures.

Giriş: Pediatrik yaş grubundaki hastaların karaciğer vasküler yapılarındaki hemodinamik değişikliklerin doppler ultrasonografi ile değerlendirilmesidir.
Materyal / Metot: Bu 82 kişilik çalışmada, hafif, orta veya şiddetli olarak sınıflandırılan 57 hepatosteatoz hastası ve 23 sağlıklı gönüllü çalışmaya dahil edildi. Deneklerin boy, kilo, karaciğer büyüklüğü testleri ölçüldü. Bu değerler hasta ve kontrol gruplarında karşılaştırıldı. Hasta ve kontrol gruplarında portal ven tepe hızını, portal ven akım hacmini, hepatik arter rezistif indeksi (Rİ), hepatik arter pulsatilite indeksini (PI) ve hepatik arter akım hacmini incelemek için renkli dupleks Doppler ultrasonografi kullanıldı.
Sonuçlar: Hepatosteatoz derecesine benzer şekilde, vücut kitle indeksindeki artışlar, karaciğer boyutu,istatistiksel olarak anlamlıydı (p<0,05). Portal ven tepe hızıi hepatosteatoz ve kontrol grupların arasındaki fark istatistiksel olarak anlamlı bulunmuştur. Hepatosteatoz derecesi arttıkça hepatik arter akım hacminde, portal ven akım hacminde ve toplam akış hacminde istatistiksel olarak anlamlı bir azalma görülmemiştir. Hepatik arter RI ve PI değerleri kontrol grubunda diğer gruplara göre istatistiksel olarak anlamlı derecede düşüktü (p <0.05). Hafif şteatoz grubunda, orta steatoz grubuna göre anlamlı hafif oranda düşüklük vardı. Hepatosteatoz grubunun kendi içinde karşılaştırılmasında, hepatik arter RI ve PI değerleri istatistiksel olarak farklılık göstermese de steatos derecesi arttıkça RI ve PI değerlerinde minimal bir artış vardı.
Tartışma: Bu sonuçlara göre steatos derecesi arttıkça portal venöz yapılardaki değişiklikler daha ön planda olmakla birlikte vasküler yapılarda direnç artışı da meydana gelmektedir.
