Transarterial embolization of carotid-cavernous sinus fistula associated with a primitive trigeminal artery-case report

BACKGROUND AND PURPOSE We evaluated our experience in placing detachable coils in the management of spontaneous CCFs due to rupture of a primitive trigeminal artery. Methods A 48-year-old female presented with right conjunctival chemosis and right abducens nerve paresis. Cerebral angiography demonstrated a right carotid-cavernous sinus fistula associated with persistent primitive trigeminal artery. Transvenous routes to the sinus were failed due to the tortuous facial vein. The fistula was treated by Matrix detachable coils and Fibered detachable coils through the transarterial approach. Results The patient was successfully treated by means of transarterial embolization, and symptoms improved within a week. Conclusions Although other techniques using a transvenous approach may also be useful, transarterial embolization with detachable coils should be a safe and effective method to immediately occlude the fistula.

Transvenous treatment of a complex cavernous sinus dural arteriovenous fistula secondary to balloon embolization of a traumatic carotid-cavernous fistula

Although recurrent traumatic carotid-cavernous fistula （CCF） and its treatment have beenreported sporadically,^1 a complex cavernous sinus dural arteriovenous fistula （DAVF） secondary to balloon embolization of a direct traumatic CCF is rare. In 2005, we treated such a case via transvenous approach using coils and N-buty-2- cyanoacrylate （NBCA）. The causes of recurrent cavernous sinus DAVF and its endovascular approach are discussed.

动脉瘤性颈内动脉海绵窦瘘的血管内介入治疗

目的回顾性分析动脉瘤性颈内动脉海绵窦瘘的诊断及经动脉血管内多方式联合治疗的经验。方法总结分析6例经血管内治疗的动脉瘤性颈内动脉海绵窦瘘资料,6例患者经查体及CT、MR、DSA等确诊,均行经动脉血管内治疗,方法包括可脱球囊闭塞瘘口,可脱球囊联合弹簧圈,应用Onyx胶封堵引流静脉、弹簧圈填塞动脉瘤及覆膜支架辅助治疗,经支架辅助下弹簧圈填塞动脉瘤。结果 1例单纯应用可脱球囊,2例联合应用球囊和弹簧圈填塞,2例应用Onyx胶封堵引流静脉、弹簧圈填塞动脉瘤及支架辅助治疗,1例经支架辅助下弹簧圈填塞动脉瘤;术后随访无手术相关并发症,1例因术前视神经损害导致患眼视力未恢复正常。结论血管内多种方式联合治疗动脉瘤性颈内动脉海绵窦瘘是有效、安全的治疗方法。
