肢体及肾脏假性动脉瘤的介入治疗

目的评价肢体及肾脏假性动脉瘤应用覆膜支架及栓塞技术治疗的价值,分析相关的并发症及处理方法。方法3例肢体假性动脉瘤应用覆膜支架置入术将其隔绝,2例肾动脉假性动脉瘤应用明胶海绵栓塞。结果5例假性动脉瘤均完全闭合,2例置入覆膜支架者其远端动脉搏动正常。1例股动脉假性动脉瘤患者术中出现支架内血栓形成,溶栓后消失。1例患者由于其他原因,致穿刺部位又出现假性动脉瘤。结论应用覆膜支架及栓塞技术可使肢体及肾脏假性动脉瘤得到有效治疗,且创伤小,恢复快,尤其适用于不能耐受传统手术治疗者,远期疗效尚待进一步观察。

Interventional therapy of pseudoaneurysm in extremities or kidneys

Objective To evaluate the value of covered metallic stent and arterial embolization in the management of pseudoaneurysm of extremities or kidneys.Methods Endovascular covered stent graft was inserted for isolation of peripheral extremity pseudoaneurysm in 3 patients and intraarterial embolization was performed with gelfoam in 2 patients for pseudoaneurysm in kidney.Results All 5 pseudoaneurysms kept occluded after the treatment.Distal arterial pulse was normal in 2 patients treated with stent graft;new thrombosis formed within the stent during the procedure but disappeared after thrombolytic therapy through catheter in 1 case;and still another new pseudoaneurysm presented at puncture site in 1 other case due to other factors.Conclusions Pseudoaneurysms in extremities or kidneys can be effectively treated with interventional techniques of covered stent graft and percutaneous arterial embolization.The long-term investigation is needed.
