Abstract：

Objective To study the utility of neuroendoscope-assisted surgery in the treatment of spinal dural arteriovenous fistulas.Methods From November 2008 to November 2010,8 cages of spinal dural arteriovenous fistulas underwent neuroendoscope-assisted surgical treatment by a hemilaminectomy approach.Retrospective analyses were performed for their clinical manifestations,imaging findings,surgical approaches,postoperative recovery and follow-up profiles.Results All were of single fisula.Under the assistance of neuroendoscope,the fistulas were found intra-operatively and the draining veins disconnected successfully.The results of post-operative angiography showed the disappearance of all draining veins.After a follow-up period of 3-35 months,2 cases became asymptomatic,5 cases improved obviously and 1 case had no change.Conclusion Neuroendoscope-assisted surgery is mini-invasive,safe and effective in the treatment of spinal dural arteriovenous fistulas.

硬脊膜动静脉瘘的临床特点和治疗现状

硬脊膜动静脉瘘(SDAVF)是一种临床表现不典型的罕见疾病,脊髓数字减影血管造影是其诊断的金标准。近年来,以脊髓磁共振血管成像、CT血管成像为代表的无创/微创血管成像技术在协助诊断SDAVF方面取得了很大进展。该病自然转归较差,如果未经有效治疗,其症状将呈波动性加重,最终可导致永久性的脊髓损伤。因此一旦确诊,应尽早采取合适的治疗,以阻断疾病进展。SDAVF的治疗方式主要包括显微外科手术和血管内介入治疗。随着医疗技术的进步,两种治疗方式均较以往取得较大进展,手术治疗准确性更高、创伤更小、效果更好。未来在临床实践中,应力争早期正确诊断SDAVF,并根据病情灵活选择和运用各种治疗方式。

Transarterial Onyx embolization of intracranial dural arteriovenous fistulas: A single center experience

BackgroundTransarterial embolization of intracranial dural arteriovenous fistulas (DAVFs) is usually associated with inadequate embolization. The purpose of this study was to report our experience of transarterial Onyx embolization of intracranial DAVFs with an emphasis on treatment outcome with this new embolic agent in different types of DAVFs.MethodsIn the past 3 years, a total of 14 intracranial DAVFs have been treated by transarterial Onyx embolization. Among these, there were nine males and five females, aged from 30 years to 82 years (mean = 62 years). We retrospectively analyzed the injection volume and time of Onyx embolization as well as outcomes in different types of DAVFs.ResultsThe locations of the DAVFs were sigmoid sinus (n = 6), tentorium (n = 3), sinus confluence (n = 2), transverse–sigmoid sinus (n = 1), sigmoid sinus–jugular bulb (n = 1) and the superior petrous sinus (n = 1). The mean volume and time of Onyx injection were 3.4 mL and 28 minutes, respectively (Cognard type I: 4.9 mL, 40 minutes; type II: 4.5 mL, 34 minutes; type III: 2.2 mL, 21 minutes; type IV: 2 mL, 22 minutes). Total fistula occlusion was achieved in six out of seven patients of type III and type IV DAVFs, and in four out of seven patients of type I and type II DAVFs. Nine patients had total resolution of their symptoms, whereas partial regression occurred in five patients. No significant periprocedural complication was found. Mean clinical follow-up period was 16 months.ConclusionTransarterial Onyx embolization of intracranial DAVFs is safe and effective. This technique is particularly useful in type III and type IV DAVFs with a high cure rate, and lower volume of Onyx as well as a short injection time.
