Metal stent implantation in treatment of portal vein cavernous transformation / 实用放射学杂志

ABSTRACT

Objective To explore the efficacy and safety of percutaneous transhepatic portal vein or transjugular intrahepatic portosystemie shunt (TIPS)to implant the portal vein metallic stent in treatment of cavernous transformation of portal vein (CTPV).Methods Clinical and imaging data of 8 patients with CTPV were retrospectively analyzed who were treated in our hospital.All patients were treated with metallic stent implantation in portal vein including 3 patients by TIPS and 5 by percutaneous transhepatic portal vein.Results All patients were successful in the stent implantation without any occurrence of serious complications such as intra-abdominal hemorrhage and so on.Intraoperative angiography showed blood circulated freely in these stents.1 day-2 weeks later,the patients symptoms of abdominal pain and gastrointestinal bleeding were obviously relieved or disappeared.Follow up 1 month-3 years,1 patient with stent occlusion after one year of operation,the blood flow recovery after stent reimplantation,and the remaining patients,color doppler ultrasound reflected patency of blood flows in their stents.No one suffered from gastrointestinal bleeding or abdominal pain again.Conclusion Implantation of portal vein metallic stent via percutaneous transhepatic portal vein or via TIPS in treatment of cavernous transformation of portal vein is safe and effective.
