Abstract: 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 embolization therapy. Results DSA confirmed that 4 patients had 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.
