Abstract:
Objective To evaluate the clinical efficacy of percutaneous ultra-fine needle CO_2 splenoportography (CO_2-SP).Methods CO_2-SP and 3D-CE-MRA were performed in 36 patients.The imaging quality of the methods was compared by a scoring criterion setup based on the visualization of the trunk,intrahepatic branches of the portal vein and collateral vessels.Results Transient mild abdominal discomfort was presented in 19 patients(52.8% )receiving CO_2-SP.One patient developed snbcapsular splenic hematoma and was discharged with clinical stability several days later after conservative treatment. The imaging quality of the intrahepatic branches of the portal vein with CO_2-SP was much more superior to 3D-CE-MRA (the score was 232 and 198 respectively,t=4.52,P0.05 ).Conclusion Ultrafine needle CO_2-SP is a minimally invasive and safe procedure,able to provide dynamic and clearer imaging of the intrahepatic branches of the portal vein.
