In recent years, the role of computational fluid dynamics for Budd‑Chiari syndrome evaluation has become the focus of certain studies. The purpose of the present study was to evaluate the role of computational fluid dynamics in Budd‑Chiari syndrome with obstruction of the inferior vena cava (IVC). Magnetic resonance venous angiography was used to obtain original IVC and hepatic venous blood flow images from patients with Budd‑Chiari syndrome. The computational fluid dynamics method was used to establish a three‑dimensional model and simulate the blood flow velocity, wall shear stress and wall pressure. The results revealed that the hemodynamic parameters of Budd‑Chiari syndrome were successfully simulated by computational fluid dynamics. The hemodynamic parameters of the IVC stenosis varied with the cardiac cycle. Vascular flow velocity (pre‑operative, 1.64±0.10 m/sec; post‑operative, 0.34±0.14 m/sec; t=34.97, P<0.001) and wall shear stress (pre‑operative, 25.69±2.85 Pa; post‑operative, 3.51±1.70 Pa; t=29.86, P<0.001) at the area of stenosis decreased after interventional therapy and the wall pressure increased (pre‑operative, ‑119.33±251.50 Pa; post‑operative, 1,128.42±207.70 Pa; t=17.10, P<0.001). In conclusion, the computational fluid dynamics method was able to effectively simulate the hemodynamic parameters of Budd‑Chiari syndrome with obstruction of the IVC and may provide an effective quantitative method for the evaluation of vascular function post‑treatment.
