目的介绍1例采用液态栓塞材料(Onyx)栓塞颅内大型多瘘口动静脉瘘(AVF)的治疗体会。方法患者以癫痫起病入院,影像学检查发现双侧额叶皮层高流量多瘘口AVF,分别由左右的大脑前动脉和左侧的大脑中动脉供应,引流静脉曲张并于右颞叶形成2个直径2.5 cm的静脉球,另外在左侧AVF的后方还伴有一小的AVF。采用液态栓塞剂Onyx分别栓塞左右额叶的瘘口。结果双侧大脑前动脉栓塞后,颅内大型AVF完全闭塞,无相关并发症。AVF后方的小AVF待随访后进一步治疗。临床随访12个月,患者恢复良好。结论新型液态栓塞剂Onyx对于供应动脉弯曲的颅内AVF具有良好的栓塞效果,且可控性好。远期疗效尚需进一步积累病例及长期随访加以验证。
Objective To introduce a case of embolization of intracranial large multiple fistula arteriovenous fistula (AVF) with liquid embolic material (Onyx). Methods The patients were admitted to hospital with epilepsy. The AVF in the bilateral frontal cortex with high-flow multi-fistula was detected by imaging examination. The left and right anterior cerebral arteries and the left middle cerebral artery were respectively supplied with the varicose veins and developed in the right temporal lobe 2 A diameter of 2.5 cm vein ball, in addition to the left side of the AVF is accompanied by a small AVF. Onyx embolization of the left and right frontal lobe fistula were used. Results After bilateral anterior cerebral artery embolization, large intracranial AVF occlusion completely without complications. AVF behind the small AVF to be followed up for further treatment. Clinical follow-up of 12 months, the patient recovered well. Conclusion Onyx, a new liquid embolization agent, has good embolization effect on intracranial AVF supplying artery flexion and has good controllability. Long-term efficacy needs to be further accumulated cases and long-term follow-up to be verified.
