AIM
To evaluate the clinical efficacy of an expanded polytetrafluoro-ethylene-covered Fluency stent compared with that of a polyethylene terephthalate-covered Wallgraft stent for the management of transjugular intrahepatic portosystemic shunt (TIPS) dysfunction.
METHODS
A retrospective review of patients who underwent TIPS revision with stent-grafts between May 2007 and June 2011 was conducted. The patients were divided into two groups according to the stent-grafts implanted: the Fluency stent (Bard Incorporated, Karlsruhe, Germany) and the Wallgraft stent (Boston Scientific, Galway, Ireland). The primary patency rates were calculated and compared using the Kaplan-Meier method.
RESULTS
A total of 73 patients were evaluated in this study: 33 with Fluency stents and 40 with Wallgraft stents. The primary patency rates at 12 and 24 mo were 91% and 85%, respectively, in the Fluency stent group and 78% and 63%, respectively, in the Wallgraft stent group. The primary shunt patency rates after TIPS revision were significantly better with the Fluency stent than with the Wallgraft stent (P = 0.033).
CONCLUSION
TIPS revision with the Fluency stent has higher medium-term patency rates than that with the Wallgraft stent.
目的
评估聚四氟乙烯覆膜 Fluency 支架与聚对苯二甲酸乙二醇酯覆膜 Wallgraft 支架治疗经颈静脉肝内门体分流术（TIPS）功能障碍的临床疗效。
方法
回顾性分析 2007 年 5 月至 2011 年 6 月期间接受 TIPS 支架置入术的患者。根据植入的支架将患者分为两组：Fluency 支架（Bard 公司，卡尔斯鲁厄，德国）和 Wallgraft 支架（波士顿科学公司，戈尔韦，爱尔兰）。采用 Kaplan-Meier 法计算并比较两组患者的初始通畅率。
结果
本研究共评估了 73 例患者：33 例患者使用 Fluency 支架，40 例患者使用 Wallgraft 支架。Fluency 支架组患者在 12 个月和 24 个月时的初始通畅率分别为 91%和 85%，Wallgraft 支架组患者分别为 78%和 63%。TIPS 支架置入术后，Fluency 支架组的初始分流通畅率明显优于 Wallgraft 支架组（P = 0.033）。
结论
与 Wallgraft 支架相比，Fluency 支架治疗 TIPS 功能障碍的中期通畅率更高。
