Short-term portal hemodynamic effects of partial splenic embolization for hypersplenism

Background/Aims: The purpose of this study was to investigate the short-term effects of partial splenic embolization (PSE) for hypersplenism. on portal hemodynamics and liver function. Methodology: Thirty-seven patients with hypersplenism were included in this study. Results: The wedged hepatic venous pressure before and after PSE were 39 +/- 10 and 33 +/- 8cmH20, respectively, showing significant change (p < 0.0 1). The flow volumes of the splenic vein before and after PSE were 477 +/- 200 and 319 +/- 187mL/min, respectively, also showing significant change W<0.05). However, the flow volumes of the portal vein before and after PSE were 713 +/- 284 and 684 +/- 152mL/min, respectively, showing no significant change. The blood laboratory parameters showed no significant change after PSE. PSE damaged neither the portal blood flow volume nor the liver function, although it improved the local hyperdynamic state in the splemic area and thrombocytopenia. Conclusions: In conclusion, PSE is a safe and effective treatment for hypersplenism from the portal hemodynamic point of view.
