Abstract:
Objective To study portal vein hemodynamics changes after autoiogous bone marrow stem cell transplantation in patients with liver cirrhosis. Methods The hemodynamic parameters, including portal vein diameter, average portal blood flow velocity and spleen size, were determined by Colour Doppler Ultrasonography in 50 patients after autologous bone marrow stem cell transplantation and all cases were followed for up to 6 months. Results (1) After autologous marrow stem cell transplantation, the portal vein diameter reduced significantly at different timepoints compared to before the treatment ([1.41 ± 0. 15] cm, [1. 38 ± 0. 11]cm,[1.36±0. 17] cm vs. [1. 53 ±0. 18] cm,t = 1. 987,1.994,1. 976, Ps < 0.05), but we found no significant difference in the comparisons among different timepoints (F = 2. 35 ,P >0.05). (2) After autologous marrow stem cell transplantation, the average portal blood flow velocity increased significantly at different timepoints compared to before the treatment ([15. 7 ± 3. 6] cm/s, [16. 1 ± 2.4] cm/s, [15. 9 ± 3.0] cm/s vs.[11.4 ± 3. 3] cm/s ,t = 2. 345, 2.460,2. 381, Ps < 0. 01) , but we found no significant differences in the comparisons among different timepoints (F = 2. 14, P > 0.05) . (3) After autologous marrow stem cell transplantation,the spleen size reduced significantly at different timepoints compared to before the treatment ([4.8±0.3]cm,[4.7±0.6]cm,[4.8±0.5]cm vs. [5. 2 ±0. 7]cm,t =2. 289,2. 390,2.425,Ps <0.01), but we found no significant differences in the comparisons among different timepoints (F = 2. 26, P > 0.05) .Conclusion The autologous bone marrow stem cell transplantation can effectively improve the portal vein blood flow,reduce the spleen size,alleviate portal hypertension in patients with liver cirrhosis.
