Giriş ve amaç: Sirozlu hastalarda Doppler ultrasonografi (DUS) ile incelenen hemodinamik değişiklikler ile portal hipertansiyon veya karaciğer fonksiyon bozukluğunun şiddeti arasındaki ilişki hakkındaki çalışmalar yetersizdir. Sirozlu hastalarda portal, hepatik, splanknik ve renal dolaşımdaki hemodinamik değişiklikleri araştırdık. Gereç ve yöntem:35 sirozlu hasta (11 Child A, 12 Child B, 12 Child C ) ve 13 sağlıklı kontrol çalışmaya alındı. DUS ile SMA' de maksimum akım hızı (MAH), rezistivite indeksi (RI) ve pulsatilite indeksi (PI), hepatik ve renal arterlerde RI ve PI, portal vende ise çap, MAH ve debi ölçüldü. Bulgular: SMA' de; MAH' ı; Child A, B ve C gruplarında kontrol grubuna göre (p her üçünde de

Background and aims: The data about the relation between the severity of liver dysfunction and portal hypertension and changes in the hemodynamic parameters obtained by Doppler US (DUS) in cirrhotic patients are insufficient. We evaluated the hemodynamic changes in portal, splanchnic, hepatic and renal arteries in patients with cirrhosis. Materials and methods: 35 consecutive cirrhotic patients (11 patients in Child A, and 12 patients each in Child B and C groups) and 13 healthy subjects as control group were included in the study. Using DUS, peak systolic flow velocity (PSFV), resistivity (RI) and pulsatility index (PI) were measured at SMA; RI and PI were measured at renal and hepatic arteries. The diameter, maximal flow velocity and flow volume of portal vein were measured. Results: PSFV values obtained at SMA were sigficantly higher in Child A, B and C groups than in control group (p
