门静脉金属内支架置入治疗门静脉海绵样变

目的：探讨经皮肝穿刺和经颈内静脉肝内门体分流术(TIPS)途径门静脉内支架置入治疗门静脉海绵样变(CTPV)的疗效及安全性。方法回顾性分析于本科治疗的8例 CTPV 患者的临床及影像学资料。所有患者均行门静脉金属内支架置入治疗,其中3例经 TIPS 途径放置,5例经经皮肝穿刺途径放置。结果所有患者支架置入均一次性成功,无腹腔内出血等严重并发症发生。术中即刻复查造影显示支架内血流通畅,术后1 d~2周患者腹痛及消化道出血症状均明显减轻或消失。术后所有患者均获得完整随访,随访1个月~3年,1例患者术后1 年复查支架闭塞,再次置入1枚支架后血流通畅,其余患者彩超提示支架内血流通畅,未再发消化道出血或腹痛。结论经皮肝穿刺或经 TIPS 途径门静脉金属内支架置入治疗 CTPV 是一种安全有效方法。

Metal stent implantation in treatment of portal vein cavernous transformation

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.
