摘要
目的评价经皮脾穿刺 CO_2门静脉造影(CO_2-SP)的临床价值。方法 36例患者均接受了 CO_2-SP 及三维 MR 增强门静脉血管成像(3D-CE-MRA),评价门静脉主干、肝内分支、门静脉开放性、侧支循环的显示情况,建立评分标准评价两者的优越性。结果 CO_2-SP 时19例患者(52.8%)出现腹部轻度不适感觉,1例出现脾包膜下血肿,经保守治疗后好转出院,16例无不适。CO_2-SP 对显示肝内门静脉分支优于3D-CE-MRA(总评分分别为232、198分,t=4.52,P<0.01);显示门静脉的侧支循环与3D-CE-MRA 比较差异无统计学意义(总评分分别为14、16分,t=0.62,P>0.05)。结论超细针直接法 CO_2-SP 具有微创、安全、动态等优点,对肝内门静脉细小分支显示效果较 MRI 更好。
Objective To evaluate the clinical efficacy of pereutaneous ultra-fine needle CO2 splenoportography （CO2-SP）. Methods CO2-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 CO2-SP. One patient developed subcapsular 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 CO2-SP was much more superior to 3D-CE-MRA （the score was 232 and 198 respectively, t = 4. 52, P 〈 0. 01 ）. The visualization of the collateral vessels of the portal vein between the two techniques was not statistically significant （ the score was 14 and 16 respectively, t = 0. 62, P 〉 0. 05 ）. Conclusion Ultrafine needle CO2-SP is a minimally invasive and safe procedure, able to provide dynamic and clearer imaging of the intrabepatic branches of the portal vein.
