Objective. Spleen transplanlation has developed to be an effective strategy for hemophilia A. But it has not been reported up to date that which kind of established solutions is most suitable for perfusion and preservation of spleen. This study aimed to establish some experiences with the comparison among Hartmann’s solution

Collins’ solution and WMO I solution

in order to instruct the clinical spleen transplantation. Methods. After the splenic artery and vein were dissociated clearly

three kinds of perfusion solutions began to perfuse the corresponding segments of spleen with a randomized sequence. When the efferent fluids from the splenic vein became clear

the perfused spleen segments were preserved for different durations with the same perfusing solution to calculate the survival rate of splencocyte（SRS） and were examined with light and electron microscopy. Results. Among the three solutions

SRS with WMO I solution was significantly higher than those of the other two（P< 0.001）. The perfused spleen with WMO I solution showed the slightest morphological changes and a significant longer preservation duration than those with the other two（P<0.05 or P< 0 01）. Conclusion. Among the three solutions

WMO I solution was most suitable for perfusion and preservation of spleen.
