双导管球囊技术治疗高流量颈动脉海绵窦瘘

目的探讨双球囊导管技术治疗高流量颈动脉海绵窦瘘(CCF)的可行性及疗效。方法随机选择1枚可脱性球囊无法闭塞的CCF患者3例，双侧股动脉置管，送2枚球囊进入瘘口，调整位置，充盈2枚球囊，使瘘口完全闭塞后再解脱球囊，观察栓塞效果和颈内动脉通畅情况，评价该技术的可行性。结果3例患者均1次性完全闭塞瘘口，颈内动脉皆通畅，操作过程简单易行，未增加介入治疗的危险性。结论双导管球囊技术能在保证颈内动脉通畅的前提下简单有效地治疗1枚球囊无法闭塞的CCF。

Double-catheter-balloon technique for embolization of high-flow carotid cavernous fistulas

Objective To study the possibility and value of double-catheter-balloon technique for embolization of high-flow carotid cavernous fistula (CCF).Methods Three high-flow CCFs, which can't be completely occluded by 1 detachable balloon, were treated with the technique. By the way of bilateral femoral arteries approach, 2 detachable balloons were advanced to the internal carotid artery (ICA). After passing through the fistula, both balloons were inflated on the venous side in order to occlude the fistula. Results All CCFs were occluded completely and the ICAs remained patent. This procedure was easy and safe without increasing the risk of interventional therapy.Conclusions The application of double-catheter-balloon technique for high-flow CCF should be an effective method of choice during failure of 1 balloon procedure and simultaneously maintainning the patency of ICAs completely.
