This study describes our technique of aggressive angioplasty with juxta-anastomotic stenting (JXAS) in the autogenous arteriovenous fistula and reviews our outcomes with this technique in its mature form.
We developed a JXAS technique during the last 7 years. Since 2006, we have placed 135 JXASs. The study period reviews 68 consecutive JXASs placed from 2008 to 2012 using the mature technique. We retrospectively analyzed the prospectively collected data. Thirty-three fistulas received JXAS for failure to mature, and 35 were mature but inadequately dialyzing fistulas (problem fistulas). The JXAS technique involves (1) treating the JXA segment as a unit, (2) aggressive angioplasty with rupture of stenoses, and (3) placement of an uncovered nitinol stent.
Technical success was 97%. Of the fistulas that had failed to mature, 75% were brought to maturity by 6 months and 88% by 12 months. Adequate dialysis was achieved in all 35 problem fistulas immediately postoperatively. Assisted fistula patency was 90% at 2 years and 80% at 4 years.
JXAS is an effective technique for maturing and maintaining the wrist radiocephalic arteriovenous fistula.
本研究描述了我们在自体动静脉内瘘中采用吻合口附近血管成形术联合支架置入术(JXAS)的技术,并回顾了该技术成熟形式下的治疗效果。
在过去7年中我们研发了JXAS技术。自2006年以来,我们共置入了135个JXAS。本研究回顾了2008年至2012年期间采用成熟技术连续置入的68个JXAS。我们对前瞻性收集的数据进行了回顾性分析。33个内瘘因成熟失败接受了JXAS治疗,35个为成熟但透析功能不佳的内瘘(问题内瘘)。JXAS技术包括:(1)将吻合口附近节段作为一个整体进行处理;(2)积极进行血管成形术以解除狭窄;(3)置入无覆膜镍钛合金支架。
技术成功率为97%。在成熟失败的内瘘中,75%在6个月时实现成熟,88%在12个月时实现成熟。所有35个问题内瘘术后立即实现了充分透析。辅助内瘘通畅率在2年时为90%,在4年时为80%。
JXAS是使腕部桡动脉头静脉内瘘成熟并维持其功能的有效技术。
