TIPSS技术在门脉癌栓性门脉高压中的应用

目的 探讨TIPSS技术在治疗门静脉癌栓合并门脉高压中的技术特点及禁忌证。方法 16例门静脉癌栓合并门脉高压症患者，9例门静脉主干完全堵塞，7例门静脉主干及分支有不同程度栓塞；6例合并门脉海绵样变；1例单纯上消化道大出血；4例单纯顽固性腹水；11例上消化道大出血合并顽固性腹水。结果 16例中11例患者成功行TIPSS治疗，技术成功率约68.8%，门脉压力从术前4.9kPa降至2.4kPa，平均降低2.5kPa，腹水减少或消失，症状缓解。平均生存136d。5例失败。结论 TIPSS是治疗门脉癌栓引起的上消化道大出血和顽固性腹水的有效方法，门脉海绵样变是该术的禁忌证。

The application of TIPSS in portal vein cancerous thrombosis complicated with portal hypertension

Objective To discuss the technical skills and the contraindication of transjugular intrahepatic portosystemic shunt stent (TIPSS) in portal vein cancercous thrombosis (PVCT) complicated with portal hypertension. Methods There were 16 cases of PVCT with portal hypertension, and average age of 53.6 yr. There were 9 cases with complete occlusion of portal vein trunk and 7 cases with incomplete thrombosis. There were 5 cases with cavernous transformation of the portal vein(CTPV). 1 case of simple upper gastro intestinal tract (GIT) massive bleeding, 4 with refractory ascites and 11 with upper GIT massive bleeding and refractory ascites. Results The procedure of TIPS was successful in 11 cases, the successful rate reached about 68.8%. The mean portal vein pressure was reduced from 4.9kPa to 2.4kPa with average 2.5kPa reduction. Ascites decreased, bleeding stopped and the clinical symptoms disappeared. The average survival period was 136 days. The procedure failed in 5 cases. Conclusions TIPSS is an effective method to control the bleeding and ascites caused by PVCT. The PV cavernous transformation was the contraindication of TIPSS.
