【摘要】目的：探讨介入置管溶栓治疗急性肾动脉栓塞的方法及临床应用价值。方法：5例急性肾动脉栓塞的患者，经增强CT和血管造影明确诊断，均为一侧肾动脉栓塞。微导丝穿过栓塞段，将微导管置入肾动脉血栓内，注入尿激酶25万～35万U，后留置导管持续泵入尿激酶2～4万U/h，持续1～3d。每天造影复查，3d后如肾动脉完全开通，则拔除导管鞘及导管。结果：5例患者患侧的肾动脉均成功开通，腰腹痛、高血压等症状明显缓解，各项实验室指标恢复正常。在抗凝和溶栓期间，没有患者出现脏器出血、黏膜出血或其他严重并发症。在溶栓后使用华法林进行口服抗凝治疗期间，没有患者出现肾栓塞或其他身体部位的栓塞。结论：介入置管溶栓术创伤小，并发症少，能迅速改善临床症状，是一种安全有效的治疗方法。
