Embolization is recognized as an important adjunct in the treatment of cerebral arteriovenous malformations (AVMs). We reviewed our results of embolizations for AVMs and discussed procedure-related complications. Eleven complications were recorded in 68 consecutive patients (16%). Of these, four were technical problems including a glued catheter, inability to withdraw the catheter, vessel perforation by the microcatheter, and coil migration. Other complications included three cases of ischemic symptoms due to retrograde thrombosis, two cases of asymptomatic cerebral infarction, one case of asymptomatic small haemorrhage due to venous occlusion, and one case of post-embolization haemorrhage of unknown etiology. Our morbidity rate was 7%, mortality rate was 0%, and asymptomatic complication rate was 9%, retorospectively. Further improvements to endovascular techniques and devices are required.
栓塞术被认为是治疗脑动静脉畸形（AVM）的重要辅助手段。我们回顾了我们对AVM进行栓塞治疗的结果，并讨论了与手术相关的并发症。在连续68例患者中记录到11例并发症（16%）。其中，4例为技术问题，包括导管粘连、无法拔出导管、微导管导致血管穿孔和弹簧圈移位。其他并发症包括3例因逆行血栓形成导致的缺血症状、2例无症状性脑梗死、1例因静脉闭塞导致的无症状小出血以及1例病因不明的栓塞后出血。回顾性分析，我们的发病率为7%，死亡率为0%，无症状并发症发生率为9%。需要进一步改进血管内技术和设备。
