Intracranial dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous communications within the dura locating near a major venous sinus and are supplied by pachymeningeal arteries. DAVFs represent 10–15% of all intracranial arteriovenous malformations. The natural history and clinical manifestations are determined by location of the DAVFs and their angioarchitecture. Aggressive DAVF is usually associated with leptomeningeal venous drains or reflux. It may present with hemorrhagic or nonhemorrhagic stroke. The goal of embolization of DAVFs is total fistula occlusion without interfering with the normal dura–venous drains. Embolization can be performed by transarterial and/or transvenous routes or direct puncture of affected dural sinus. Selection of embolic materials depends on access route and angioarchitecture of the fistula. With the involution of endovascular devices, embolic materials, and high-quality angiography, endovascular embolization of DAVFs has been proved a safe and effective method of treating these complex cerebrovascular lesions. 相似文献

Embolization therapy has been used as the initial treatment for spinal dural arteriovenous fistula (SDAVF) only for certain patients or in certain medical institutions due to its minimal invasiveness, but the recurrence of embolization remains a clinical challenge. The recurrent patient usually exhibits a gradual onset of symptoms and progressive deterioration of neurological function. Developing paraplegia several hours after embolization is commonly seen in patients with venous thrombosis-related complications, for which anticoagulation therapy is often administered. This article reports on a SDAVF patient who had weakness of both lower extremities before embolization and developed complete paraplegia several hours after embolization therapy, later confirmed by angiography as fistula recurrence. The symptoms were relieved gradually after second embolization. The pathophysiology of this patient is also discussed. 相似文献

目的: 通过meta分析比较显微外科手术与血管内栓塞治疗硬脊膜动静脉瘘的临床疗效。方法: 计算机检索PubMed、Embase、Web of Science、Cochrane临床试验数据库、中国知网、万方数据库、中国生物医学文献数据库(Chinese BioMedical Literature Database,CBM),检索时间从数据库建库至2019年12月,纳入采用显微外科手术和血管内栓塞治疗硬脊膜动静脉瘘的所有中英文文献。使用RevMan 5.3软件进行统计学分析,评估术后早期失败率、远期复发、神经功能恢复程度、并发症情况,比较两种治疗方式对硬脊膜动静脉瘘的临床疗效,并对血管内栓塞治疗进行亚组分析。结果: 纳入文献46篇,共1 958例硬脊膜动静脉瘘患者,其中935例采用显微外科手术治疗,1 023例采用血管内栓塞治疗,漏斗图显示未见明显发表偏倚。经meta分析结果显示,显微外科手术早期治疗失败的发生率低于血管内栓塞治疗( OR=0.20, 95% CI: 0.13~0.30, P<0.05),远期复发率也低于血管内栓塞治疗( OR=0.36, 95% CI: 0.22~0.58, P<0.05),显微外科手术治疗后患者神经功能改善情况优于血管内栓塞治疗的患者( OR=2.86, 95% CI: 1.36~5.99, P<0.05),两种治疗方式患者并发症的发生率差异无统计学意义( OR=1.52, 95% CI: 0.88~2.64, P=0.14)。血管内栓塞治疗的患者中,使用Onyx胶进行栓塞比使用α-氰基丙烯酸正丁酯(n-butyl 2-cyanoacrylate,NBCA胶)有更高的治疗失败或复发风险,差异有统计学意义( OR=4.70, 95% CI: 1.55~14.28, P<0.05)。结论: 虽然血管内栓塞治疗硬脊膜动静脉瘘的应用日趋广泛,但显微外科手术所获得的临床疗效仍明显优于血管内栓塞治疗。 相似文献

Objective:To evaluate the safety and efficiency of transvenous embolization of dural arteriovenous fistula of cavernous region by multiple venous routes. Methods: Twenty seven patients with dural arteriovenous fistula of cavernous region were treated by transvenous embolization with micro-coils. The transvenous routes included inferior petrosal sinus, superior ophthalmic vein and facial vein. Results: Clinical cure was achieved in 23 cases and significant improvement of symptoms in 4 cases. Complete anglographic obliteration was documented in 22 patients (82%). Residual shunting were left in 2 patients via pterygoid drainage and 1 case via inter-cavernous sinus, 2 cases via inferior petrosal sinus, disappeared one month later by manual compression carotid artery. Headache and vomiting were the most common symptoms after embolization. Three patients had diplopia and relieved within two months after embolization. There was no permanent procedure-related morbidity. The clinic follow up ranged from 5 months to 6 years, and there was not recurrence case. Conclusion: Transvenous embolization via different venous routes is a safe and efficient method for dural arteriovenous fistula of cavernous region treatment. 相似文献

Background Usually, cavernous dural arteriovenous fistula can be treated via transarterial approaches. However, in many complicated patients, transvenous approaches are superior to the transarterial ones because of the difficulties during a transarterial operation. In this study, we retrospectively analyzed the outcomes of 28 patients with cavernous dural arteriovenous fistula treated by transvenous embolization. Methods From September 2001 to December 2005, 28 patients with 31 cavernous dural arteriovenous fistulae were treated with transvenous embolization in Beijing Tiantan Hospital. The involved cavernous sinuses were catheterized via the femoral vein-inferior petrosal sinus approach or the femoral-facial-superior ophthalmic vein approach, and embolized with coils (GDC, EDC, Matrix, Orbit or free coil) or coils plus silk. The patients were followed up for 3 to 26 months. Results All the 31 cavernous sinuses in the 28 patients were successfully embolized. Complete angiographic obliteration of the fistulae was achieved immediately in 25 patients. Residual shunting was observed in the other 3, who had drainage through the pterygoid plexus (2 patients) or the inferior petrosal sinus (1) after the operation. Headache and vomiting were the most common symptoms after the embolization. In 3 patients, who achieved complete angiographic obliteration immediately, the left oculomotor nerve palsy remained unchanged after the operation. Transient abducens nerve palsy was encountered in 1. In 1 patient, the occular symptoms were improved after the operation, but recurred 4 days later, and then disappeared spontaneously after 5 days. During the follow-up, no patient had recurrence. Three months after the operation, angiography was performed on the 3 patients with residual shunting. Two of them had angiographic cure, the other had residual drainage through the pterygoid plexus. Conclusions Transvenous catheterization and embolization of the cavernous sinus is a safe and efficient way to treat complicated cavernous dural arteriovenous fistulae. It is an alternative to the patients with spontaneous cavernous dural arteriovenous fistulae or those in whom transarterial embolization failed. 相似文献

Although recurrent traumatic carotid-cavernous fistula (CCF) and its treatment have beenreported sporadically,^1 a complex cavernous sinus dural arteriovenous fistula (DAVF) secondary to balloon embolization of a direct traumatic CCF is rare. In 2005, we treated such a case via transvenous approach using coils and N-buty-2- cyanoacrylate (NBCA). The causes of recurrent cavernous sinus DAVF and its endovascular approach are discussed. 相似文献
