To evaluate the safety and efficacy of embolization via transvenous approaches in patients diagnosed with Cavernous Sinus Dural Arteriovenous Fistula (CSDAVF). We also hope to further summarize our preliminary experiences with transvenous approaches.
We retrospectively collected data from patients who were diagnosed with CSDAVF and were treated with embolization via transvenous approaches from June 2014 to November 2020 at Beijing Tiantan Hospital. We evaluated the safety and efficacy of this treatment using radiological results and clinical follow-up.
A total of 83 patients were included in this study. Complete occlusion was obtained in 76 (89.4%) patients. Sub-total occlusion was obtained in eight (9.4%) patients. Partial occlusion was obtained in one (1.2%) patient. There was no recurrence. Seventy-six patients (91.5%) were cured, and seven patients showed symptom improvement (8.5%). There were no cases of worsening symptoms following embolization, and only ten (12.0%) cases had mild complications.
There was a high occlusion rate and a low complication rate in our study. Thus, completing embolization of CSDAVF via transvenous approaches may be safe and effective. However, this operation is more difficult than those via transarterial approaches. Transvenous embolization should therefore be performed in an experienced medical center.
评估经静脉途径栓塞治疗海绵窦硬脑膜动静脉瘘（CSDAVF）患者的安全性和有效性。我们还希望进一步总结我们经静脉途径栓塞治疗的初步经验。
我们回顾性收集了 2014 年 6 月至 2020 年 11 月在北京天坛医院接受经静脉途径栓塞治疗的 CSDAVF 患者的数据。我们通过影像学结果和临床随访评估了这种治疗的安全性和有效性。
本研究共纳入 83 例患者。76 例（89.4%）患者获得完全闭塞，8 例（9.4%）患者获得次全闭塞，1 例（1.2%）患者获得部分闭塞。无复发。76 例（91.5%）患者治愈，7 例症状改善（8.5%）。栓塞后无症状恶化，仅有 10 例（12.0%）出现轻度并发症。
本研究中闭塞率高，并发症发生率低。因此，经静脉途径完全栓塞 CSDAVF 可能是安全有效的。然而，该手术比经动脉途径更具难度，因此应在有经验的医疗中心进行。
