The aim of this work is to evaluate the role of Ultrasound-Doppler in the hemodynamic study of hepatic vessels during the liver cirrhosis in Togo. Method: This was an analytic cross-sectional study that measured the velocimetric parameters of hepatic vessels in cirrhotic patients and in non-cirrhotic patients. Results: The velocimetric parameters of the hepatic artery, the portal vein, and the hepatic veins were measured in 50 cirrhotic patients and 50 non-cirrhotic The caliber of the portal vein was significantly increased in cirrhotic patients compared to non-cirrhotic patients with 13.11 ± 2.16 mm versus 11.45 ± 1.02 (p < 0.00006). The systolic velocity and the hepatic artery resistance index were significantly raised in the cirrhotic patients compared to the non-cirrhotic with 67.32 ± 22.77 versus 49.97 ± 17.24 (p-value < 0.00004) respectively, and 0.78 ± 0.07 against 0.72 ± 0.08 (p < 0.00006). The caliber of the hepatic veins was significantly decreased in the cirrhotic patients compared to the non-cirrhotic patients (p < 0.0003). There was no correlation between the gender of the patients and the change in the hemodynamics of the hepatic vessels. Conclusion: The hemodynamic study of the hepatic vessels can and must rightly be a diagnostic argument for liver cirrhosis.
