Study of the relationship between portal vein thrombosis and post-splenectomy fever

Objective To investigate the relationship between portal vein thrombosis and post-splenectomy fever in patients with portal hypertension.Methods Clinical data of 212 cases undergoing splenectomy plus devascularization due to portal hypertension and 110 cases of splenectomy due to injury were analyzed retrospectively to observe the incidences of postoperative portal vein thrombosis and fever.Results Of the 212 cases of splenectomy plus devascularization due to portal hypertension,153 underwent color Doppler ultrasonography.The incidences of portal vein thrombosis and persistent fever were 38.6%(59/153) and 17.6%(27/153) respectively.83 of 110 cases with splenectomy due to injury underwent color Doppler ultrasonography,and the incidences of portal vein thrombosis and persistent fever were 16.9%(14/83) and 2.4%(2/83) respectively.Conclusions There is no significant correlation between portal vein thrombosis and postoperative fever.
