Abstract：
UNASSIGNED: Stenting of central venous stenosis to preserve upper extremity hemodialysis access is well-described, though upper extremity complications secondary to these stents are less frequently discussed.
UNASSIGNED: We present the case of a 43-year-old male with a right brachiocephalic fistula who developed symptoms of venous hypertension following placement of a Wallstent for central venous stenosis. Workup demonstrated venous outflow obstruction secondary to stent foreshortening into the right subclavian vein.
UNASSIGNED: The Wallstent was removed in a piecemeal fashion using an open surgical technique and a HeRO graft was placed for dedicated fistula outflow with complete relief of the patient\'s symptoms.
UNASSIGNED: In situations where a stent has migrated and endovascular removal is not possible, individual Wallstent fibers can be removed through a limited venotomy.

摘要：
■为保持上肢血液透析通路而对中心静脉狭窄进行了很好的描述，尽管这些支架继发的上肢并发症较少讨论。
■我们介绍了一个43岁的男性，患有右头臂瘘，在放置Wallstent治疗中心静脉狭窄后出现静脉高压症状。检查显示，静脉流出道阻塞继发于右锁骨下静脉的支架缩短。
■使用开放式手术技术以零碎方式移除Wallstent，并放置HeRO移植物用于专用瘘管流出，从而完全缓解患者的症状。
■在支架已迁移且无法进行血管内移除的情况下，可以通过有限的静脉切开术去除单个Wallstent纤维。
