摘要
本文报道了7例门静脉结构异常的影象诊断,包括门静脉海绵样变3例,门静脉重度狭窄2例,门静脉畸形1例,1例门静脉海绵样变血管结构同正常门静脉系统同时存在。检查方法包括US、CT、MRI和动脉法门静脉造影,US和MRI对门静脉结构异常的显示尚不能为TIPSS治疗提供满意的信息,正确诊断率有待进一步提高,在行TIPSS治疗的前,如疑有门静脉结构异常,应行间接门静脉造影,以判断TIPSS治疗可行性。
The imaging of stucture abnormality of the portal vein(PV) in seven patients was investigated,The abnormality included 3 cases of portal vein cavernous transformation (PVCT), severe stenosis of PV in 2 cases, congenital malformation in 1 case, and coexistance of PVCT with mormal Portal vein in 1 case. The observation of the PV was by means of angiography as well as US, CT, MRi and the prior one is the major process for the final diagnosis. The indirect angiography of PV is necessory to the placement of transjugular intrahepatic porto-systemic shunt stent(TIPSS), because of the false negative of US, MRI for the structure abnormality of PV, particularlly, when the observation of the PV with US, MRI is not satisfactory. The importance of structure abnormality of PV to the TIPSS was discussed in detail.
