近端血流阻断增压技术栓塞岩尖部硬脑膜动静脉瘘

Embolization of dural arteriovenous fitula at the petrous apex region with pressure cooker technique

目的探讨应用近端血流阻断技术(PCT)栓塞岩尖部硬脑膜动静脉瘘(DAVF)的操作要点及治疗效果。方法回顾性分析2015年10月至2016年2月首都医科大学宣武医院神经外科收治的4例岩尖部DAVF患者的临床资料,采用PCT技术进行栓塞治疗。结果 DSA证实4例患者多支动脉供血的岩尖部DAVF,由岩上静脉引流,采用PCT栓塞患者术后复查DSA,均证实完全栓塞,术后3个月随访症状得到改善。结论对于多支动脉供血的岩尖部DAVF,初步经验显示PCT技术能够提高栓塞效率,从而获得解剖治愈。

Objective To investigate the operation key points and therapeutic effect using the pressure cooker technique （PCT） for embolization of the dural arteriovenous fistula （DAVF） at the petrous apex region. Methods The clinical data of 4 patients with DAVF at the petrous apex region admitted to the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from October 2015 to February 2016 were analyzed retrospectively. The PCT technique was used to conduct embolizatian therapy. Results DSA confmmed that 4 patients bad DAVF at the petrous apex region with the multi- branch artery blood supply and they were drained via the superior petrosal veins. The patients were embolized by using PCT. DSA confirmed that they were embolized completely after procedure. They were followed up at 3months after surgery and their symptoms were improved. Conclusion For DAVF at the petrous apex region with the multi-branch artery blood supply, the preliminary experience shows that PCT technique may improve the efficiency of embolization,thereby obtaining anatomical cure.
