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.
■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。
