静脉窦内球囊保护下Onyx栓塞侧窦区硬脑膜动静脉瘘的随访分析

Onyx embolization of lateral sinus dural arteriovenous fistula under the balloon protection:a follow-up analysis

目的初步探讨侧窦区硬脑膜动静脉瘘的栓塞治疗中,静脉窦内球囊保护技术的疗效及安全性。方法回顾性连续纳入2012年12月至2016年8月,经静脉窦内球囊保护下,使用Onyx栓塞侧窦区硬脑膜动静脉瘘7例患者,并对其临床资料、影像学资料及随访结果进行分析。结果 7例患者中,瘘口位于乙状窦区3例、横窦区4例。术后即刻造影显示完全栓塞5例,大部分栓塞2例,球囊保护静脉窦均保持通畅。临床随访7例,随访时间为术后6~43个月,无新发神经功能缺损。7例患者均获全脑DSA复查,随访时间为术后6~11个月,提示5例完全治愈,其中4例静脉窦通畅,1例闭塞;1例瘘口稳定且静脉窦通畅,1例瘘口新发合并静脉窦闭塞。结论静脉窦内球囊保护下栓塞硬脑膜动静脉瘘在栓塞瘘口的同时,可长期维持静脉窦通畅,有利于维持栓塞效果的稳定性。

Objective To preliminarily discuss the efficacy and safety of balloon protection technique in venous sinus in the embolization of lateral sinus dural arteriovenous fistula. Methods From December 2012 to August 2016,7 consecutive patients with lateral sinus dural arteriovenous fistula embolized with Onyx under the protection of venous sinus balloon were enrolled retrospectively. Their clinical data, imaging data, and follow-up results were analyzed. Results In 7 patients, the fistulas of 3 cases were located in the sigmoid sinus and the fistulas of 4 cases were located in the transverse sinus. Immediately after operation, 5 patients were embolized completely and 2 were embolized mostly. All balloon protected venous sinuses maintained patency. Seven patients were followed up clinically and the follow-up time was 6-43 months. No new neurological deficits were observed. All 7 patients received whole DSA reexamination and the follow-up time was 6-11 months. It is suggested that 5 patients were completely cured, among them,the venous sinuses were patent in 4 cases, the venous sinus was occluded in 1 case ; the fistula was stable and venous sinus patency in 1 ease;and 1 had newly complicated venous sinus occlusion. Conclusion At the same time of embolization of the fistulas, the dural arteriovenous fistulas were embolized under the protection of venous sinus balloon. It could maintain long-term patency of venous sinus and be conductive to maintaining the stability of the embolization effect.
