Abstract

Abstract: Objective To observe the changes of hepatic hemodynamics by ultrasonography before and after splenectomy in patients with hepatolenticular degeneration（HLD） complicated by hypersplenism. Methods 108 patients with HLD were recruited and they all received color doppler ultrasonography before and after splenectomy. The inner diameter and maximum velocity of right portal vein （Vmax）,peak systolic velocity （PSV） and resistance index（RI） of right hepatic artery were recorded and analyzed. Results The inner diameters of right portal vein before and after splenectomy were （9.09±2.16） mm and （8.48±1.88） mm,respectively（P>0.05）;Vmax of right portal vein after splenectomy declined remarkably as compared with that before splenectomy[（19.40±3.41） cm/s vs.（23.47±5.78） cm/s,P<0.01];PSV and RI of right hepatic artery after splenectomy were significantly higher than those before surgery [（60.71±11.85） cm/s vs. （40.33±8.83） cm/s and （0.66±0.05） vs. （0.63±0.05）,P<0.01 for both]. Conclusion Prominent changes in blood supply of portal venous system and hepatic artery system in patients with HLD and hypersplenism take place after splenectomy. Ultrasonography can monitor the changes of hepatic hemodynamics and provide information for the evaluation of patients' liver function.
