摘要:
目的探索中心静脉狭窄支架置入术后支架断裂错位的处理措施。 方法以 1 例因“右前臂动静脉内瘘处疼痛 1 月余”入院的肾衰竭置管透析的老年男性患者为对象，分析其右上肢静脉造影特点，从中探索其处理方法。 结果造影结果显示右前臂桡静脉、头静脉血流缓慢，局部表浅静脉迂曲、增粗，肱静脉中段大量侧枝循环形成，上腔静脉近端呈支架置入术后改变，支架近端见一局限性狭窄，且支架中段断裂、错位；遂置入 10 mm×40 mm 球囊再次扩张狭窄段及支架，造影示：狭窄基本解除，支架内血流恢复通畅；术后患者右前臂无疼痛，右上肢体水肿完全消退。 结论对于支架置入术后上肢疼痛的患者应考虑支架错位甚至断裂的可能；造影是明确支架状态的最有效措施，且可直接指导支架异常的处理。 -
