PURPOSE
To report cases of stent and stent-graft fracture in the subclavian vessels.
METHODS AND RESULTS
Three patients with self-expanding stents of 3 different types in 1 subclavian artery and 2 subclavian veins presented with recurrent symptoms 6 months to 2 years after stenting. All devices showed signs of compression with stent fracture. The covered stent in the subclavian artery was excised. Of the 2 venous patients, 1 was treated with first rib resection and the other refused further treatment.
CONCLUSIONS
The subclavian vessels are prone to flexion during movement, and the vessels may be compressed by external structures, including the clavicle and first rib. Stents that have not been designed to withstand these forces may be damaged.
目的
报告锁骨下血管内支架及覆膜支架断裂的病例。
方法与结果
3例患者在1条锁骨下动脉和2条锁骨下静脉置入了3种不同类型的自膨式支架，在支架置入后6个月至2年出现复发症状。所有装置均显示有受压及支架断裂迹象。切除了锁骨下动脉的覆膜支架。2例静脉病变患者中，1例接受了第一肋切除术，另1例拒绝进一步治疗。
结论
锁骨下血管在活动时易于弯曲，且血管可能被包括锁骨和第一肋在内的外部结构压迫。未设计用于承受这些力量的支架可能会受损。
