Onyx-18和(或)弹簧圈栓塞治疗海绵窦区硬脑膜动静脉瘘(附17例报道)

目的探讨Onyx-18和(或)弹簧圈血管内栓塞治疗海绵窦区硬脑膜动静脉瘘(DAVF)的安全性和有效性。方法回顾性分析17例经Onyx-18和(或)弹簧圈血管内栓塞的海绵窦区DAVF患者的临床疗效及随访资料,栓塞治疗方式选择Onyx-18和(或)弹簧圈,单用经静脉途径治疗或单用经动脉途径治疗或经静脉+动脉联合途径治疗。结果 17例海绵窦区DAVF患者中,11例治愈,6例改善。单用经静脉途径治疗10例,治愈率为70%(7/10例);单用经动脉途径治疗3例,治愈率33.3%(1/3例);经静脉+动脉途径联合治疗4例,治愈率75%(3/4例)。所有经治病例均无严重致残和致死并发症。结论海绵窦区DAVF的血管内治疗应建立在正确认识该部位DAVF解剖特点的基础上。Onyx-18和(或)弹簧圈栓塞治疗海绵窦区DAVF是安全有效的方法。经静脉途径治疗及联合经静脉+动脉途径治疗优于单纯经动脉途径治疗。

Occurrence of De Novo Dural Arteriovenous Fistula after Transvenous Embolization of Dural Arteriovenous Fistula : Case Reports of Two Patients

Development of de novo dural arteriovenous fistula (DAVF) at a different site after resolution of an initial DAVF, is rare. Here we report two cases, which we encountered in our hospital. A 68-year-old woman presented with pulsatile tinnitus on the left side. Cerebral angiography demonstrated a left anterior condylar confluence (ACC) DVAF and she underwent transvenous embolization. Four years after this treatment, she presented with tinnitus on the left side, and cerebral angiography revealed a right DAVF around the sinus of the lesser sphenoid wing. Another 69-year-old woman presented with left-sided orbital bruits, chemosis, and conjunctival hyperemia. Cerebral angiography showed left cavernous sinus (CS) DAVF, for which she underwent transvenous embolization for CS DAVF. One year later, she developed a left ACC and transverse-sigmoid sinus (TSS) DAVF.

25例硬脊膜动静脉瘘患者的临床特征分析

目的 分析硬脊膜动静脉瘘（spinal dural arteriovenous fistula,SDAVF）的临床特征,提高临床医师对SDAVF的认识,减少误诊、漏诊。方法 回顾性收集2015年1月-2020年12月北京丰台右安门医院收治的SDAVF患者的病历资料,描述性分析其一般资料、临床表现、脑脊液检查、影像学特点、治疗及预后。结果 共纳入25例患者,其中男性21例（84.0%）,发病年龄40～75岁,中位发病年龄61岁。临床表现为运动障碍25例（100.0%）,感觉障碍22例（88.0%）,尿便功能障碍16例（64.0%）,腰背部疼痛3例（12.0%）,呼吸费力、构音障碍、吞咽困难2例（8.0%）。脑脊液检查示白细胞计数升高2例（18.2%,2/11）,蛋白水平升高8例（72.7%,8/11）。MRI均表现为长节段脊髓病变,19例（76.0%）位于胸腰段,2例（8.0%）位于骶段,4例（16.0%）位于颈段及颅颈交界区。19例（76.0%,19/25）髓周可见血管流空影,11例（61.1%,11/18）髓质不规则片状强化或伴脊髓表面线样强化,其中5例（45.5%,5/11）呈现“断层征”。CTA检查的瘘口检出率为93.3%（14/15）,供血动脉检出率为80.0%（12/15）。DSA检查示23例（92.0%）为单瘘口,2例（8.0%）为双瘘口。所有患者均行瘘口切除术或血管内介入栓塞治疗,中位随访5（3～6）个月,4例（16.0%）失访,完成随访的21例患者采用改良Aminoff-Logue评分评价预后,其中17例（81.0%）改善,3例（14.3%）无缓解,1例（4.8%）恶化。结论 SDAVF多发生于脊髓胸腰段,以进行性运动、感觉及尿便功能障碍为主要临床表现,颅颈交界区SDAVF可出现脑干功能障碍甚至危及生命。脑脊液检查可呈类炎症反应,脊髓增强MR“I 断层征”有助于SDAVF的早期识别,CTA检查可作为SDAVF的常规筛查手段。SDAVF容易误诊,早期诊治可改善预后。     

颅颈结合区硬脑膜动静脉瘘的临床和影像学特征

目的 总结颅颈结合部硬脑膜动静脉瘘（dural arteriovenous fistula,DAVF）患者的影像学和临床 特征。 方法 回顾性分析2005年8月-2016年7月在成都市第五人民医院经DSA确诊的16例颅颈结合部 DAVF患者临床资料及其DSA、CTA和MRI影像信息。根据发病时间将患者分成急性（7 d内）、亚急性（1 个月内）和慢性（超过1个月）三组。 结果 确诊的患者急性组4例、亚急性组4例和慢性组8例,其中急性和慢性患者中男性比例均为 75.0%,高于亚急性患者（50.0%）。在静脉引流方向上,有7例（87.5％）的慢性患者引流方向向上, 而急性和亚急性患者静脉引流向上的比例分别为3例（75.0%）和2例（50.0%）。所有患者在临床上均 出现头痛、恶心等非特异性症状。DSA影像显示DAVF在颅颈结合区集中在C1神经根处、双侧乙状窦处、 横窦区、右脑膜后动脉近横窦处、右侧硬脊膜动静脉瘘瘘口、左/右侧椎动脉区、枕大孔区、右侧脑 膜中动脉分支、窦汇区、天幕区和双侧海绵窦。5例患者接受了CTA检查,其中4例CTA影像呈阳性,显 示出蛛网膜下腔出血或血管的数目、形状和粗细上的改变;12例患者行脊髓MRI平扫检查,均显示被 检者出现异常流空血管,并在脑实质区出现异常信号。 结论 颅颈结合部DAVF的临床表现与颅颈结合部位置无关,与静脉引流的方向有关,CTA和MRI有 助于DAVF诊断,但确诊需要DSA检查。     

Vagal Nerve Palsy After Transarterial Embolization of Transverse-Sigmoid Dural Arteriovenous Fistula Using Onyx

We report a case of a 70-year-old man who developed a transverse-sigmoid dural arteriovenous fistula (TS-DAVF) that was successfully treated by transarterial embolization (TAE) with Onyx.

Multimodality Evaluation of Dural Arteriovenous Fistula with CT Angiography,MR with Arterial Spin Labeling,and Digital Subtraction Angiography: Case Report

Dural arteriovenous fistulae (DAVF) are cerebrovascular lesions with pathologic shunting into the venous system from arterial feeders. Digital subtraction angiography (DSA) has long been considered the gold standard for diagnosis, but advances in noninvasive imaging techniques now play a role in the diagnosis of these complex lesions. Herein, we describe the case of a patient with right‐side pulsatile tinnitus and DAVF diagnosed using computed tomography angiography, magnetic resonance with arterial spin labeling, and DSA. Implications for imaging analysis of DAVFs and further research are discussed.     

Digital Subtraction Angiography‐Dynavision in Pretreatment Planning for Embolization of Dural Arterio‐Venous Fistulas

BACKGROUND AND PURPOSE

We have found DSA‐Dynavision with multiplanar reconstruction very helpful in understanding the complex anatomy and planning of treatment of carotico‐cavernous fistulas. The purpose of our study was to examine whether using DSA‐Dynavision in pretreatment planning results in better outcome after endovascular treatment of dural arterio‐venous fistulas (dAVFs).

METHODS

Patients with dAVF treated with endovascular embolization were retrospectively identified from our interventional neuroradiology database. Patients were assessed and divided into those with DSA‐Dynavision and those without. They were compared for procedural time, angiographic evidence of cure, rates of resolution of cortical venous reflux (CVR), complications, and need for postembolization surgery.

RESULTS

Eighty‐six percent of 28 patients (mean age 57 years, range 1.67‐84 years) had Borden type 3 DAVF; 7% had Borden type 2; and 7% had Borden type 1. DSA‐Dynavision was used in 14 of 28 (50%) patients. Fewer patients with DSA‐Dynavision required postendovascular embolization surgery (7% vs. 50%, P = .01) and fewer DSA‐Dynavision patients had CVR postprocedure (29% vs. 71%, P = .023). Mean procedural time (207 vs. 249 minutes; P = .40); permanent neurological complication rates (7% vs. 7%, P = 1.0); rate of immediate angiographic occlusion (64% vs. 29%, P = .061), and reported resolution of symptoms (79% vs. 53%, P = .18) were not significantly different. There was no significant difference in follow‐up (mean: 75 vs 120 weeks, P = .47).

CONCLUSION

The use of DSA‐Dynavision in planning of endovascular treatment of dAVF is associated with higher rates of elimination of CVR and less need for postembolization surgery.     

320排CTA对硬脊膜动静脉瘘的诊断价值

目的 探讨320排CT血管成像(CTA)对硬脊膜动静脉瘘(SDAVF)的诊治价值.方法 回顾性分析11例SDAVF病人的临床资料,均行320排CTA及DSA检查,以病变的定性诊断、供血动脉、瘘口、引流静脉的显示情况及手术治疗效果等作为观察指标进行分析.结果 320排CTA对11例病人均做出正确诊断,DSA首次检查漏诊2例,经行320排CTA获得相关图像信息后再行DSA检查发现病变.所有病人经手术治疗后随访3个月～2年,短期预后均良好,但术后9～12个月出现神经功能障碍加重3例.结论 320排CTA可良好地立体显示SDAVF病灶的特征及其周围的骨性解剖结构,但其不能动态显示病灶的血流动力学改变,尚不能取代DSA检查.     

Paradoxical Exacerbation of Symptoms with Obstruction of the Venous Outflow after Gamma Knife Radiosurgery for Treatment of a Dural Arteriovenous Fistula of the Cavernous Sinus

A 59-year-old female presented with progressive right proptosis, chemosis and ocular pain. An imaging work-up including conventional catheter angiography showed a right-sided dural arteriovenous fistula of the cavernous sinus, which drained into the right superior petrosal sinus, right superior ophthalmic vein, and right inferior ophthalmic vein, and cortical venous reflux was seen via the right petrosal vein in the right posterior fossa. After failure of transvenous embolization, the patient underwent Gamma Knife radiosurgery (GKRS). At one month after GKRS, she developed increasing ocular pain and occipital headache. Repeat angiography showed partial obliteration of the fistula and loss of drainage via the superior and inferior ophthalmic veins with severe congestion, resulting in slow flow around the right cerebellar hemisphere. Prompt transarterial embolization relieved the patient''s ocular symptoms and headache. We report on a case of paradoxical exacerbation of symptoms resulting from obstruction of the venous outflow after GKRS for treatment of a dural arteriovenous fistula of the cavernous sinus.
