目的:介绍Onyx治疗脑动脉瘤和动静脉畸形。方法;采用Onyx栓塞4例颅内中～大型动脉瘤和1例巨大型动脉瘤,以及3例巨大型脑动静脉畸形。结果:5例脑动脉瘤中3例获得100％栓塞,2例95％以上栓塞,载瘤动脉均保持通畅。临床恢复良好,仅1例颈内动脉海绵窦段动脉瘤患者术后动眼神经麻痹症状略有加重。3例巨大脑动静脉畸形一次栓塞35％～40％左右。结论:Onyx栓塞中～大型和巨大型宽颈动脉瘤、栓塞脑动静脉畸形有独特的优越性,但长期疗效有待随访。
Objective: To introduce Onyx for the treatment of cerebral aneurysms and arteriovenous malformations. Methods: Onyx embolization in 4 cases of intracranial medium to large aneurysms and 1 case of giant aneurysm, and 3 cases of giant cerebral arteriovenous malformations. Results: In 5 cases of cerebral aneurysms, 100% embolization was achieved in 3 cases, and 95% embolization in 2 cases. All the parental arteries were unobstructed. Clinical recovery was good, only 1 case of carotid artery aneurysm sinus aneurysm patients postoperative oculomotor nerve paralysis symptoms aggravated slightly. Three cases of cerebral arteriovenous malformations embolization 35% to 40%. Conclusion: Onyx embolization ~ large and large wide-necked aneurysms, embolized cerebral arteriovenous malformations have unique advantages, but long-term efficacy remains to be followed up.
