目的 通过对３２７ 例脑动静脉畸形血管内治疗的分析， 探索导致各种并发症的相关因素， 以避免或减少血管内治疗并发症的发生。方法 对６０８ 例次采用不同栓塞材料进行血管内栓塞治疗产生不同并发症的分析， 其中胶栓塞后出血４ 例、水肿１５ 例、误栓４ 例、血管痉挛３ 例， 线段栓塞出血２ 例、水肿１２ 例、误栓２ 例、血管痉挛１９ 例， 探讨栓塞治疗中出现不同并发症的因素。探索避免或减少并发症的有效措施。结果 脑动静脉畸形血管内治疗并发症不仅与栓塞技术有关， 更与选用不适当的栓塞材料和栓塞材料的用量有明显关系， 其中线段多导致术中、术后血管痉挛； 多聚体类（ＩＢＣＡ、ＮＢＣＡ） 使用难度较大， 多引起脑水肿及脑出血并发症。结论 要提高脑动静脉畸形栓塞治疗的治愈率， 减少并发症， 除了有熟练的操作技术外还应根据病变的具体情况， 选择合适的栓塞材料、及其用量， 必要时与γ刀、Ｘ刀联合治疗。
OBJECTIVE: To analyze the intravascular treatment of 327 cases of cerebral arteriovenous malformations and explore the related factors leading to various complications in order to avoid or reduce the occurrence of endovascular complications. Methods 608 cases of different embolization materials for endovascular treatment of different complications were analyzed, including plastic bleeding after embolization in 4 cases, 15 cases of edema, misdiagnosis in 4 cases, 3 cases of vascular spasm, 2 cases of segmental hemorrhage, edema 12 cases, 2 cases of erroneous suppository and 19 cases of vascular spasm. The factors that caused different complications in embolization were discussed. Explore effective measures to avoid or reduce complications. Results The complications of endovascular treatment of cerebral arteriovenous malformations were not only related to the embolization technique, but also significantly related to the dosage of improper embolization materials and embolic materials. Among them, the intracranial and postoperative vasospasm were mostly caused by the line segments; IBCA, NBCA) more difficult to use, and more cause cerebral edema and cerebral hemorrhage complications. Conclusion To improve the cure rate of cerebral arteriovenous malformation embolization and reduce complications, in addition to skilled surgical techniques should also be based on the specific circumstances of the lesion, select the appropriate embolic material, and its dosage, if necessary, γ knife, X knife Combination therapy.
