“…DAVFs generate a set of clinical signs and symptoms arising from venous hypertension and pial venous rupture (3,5,8). Patients with unruptured DAVFs may remain asymptomatic or develop headache, diplopia, proptosis, epilepsy, dementia, neuropsychiatric disturbances, or myelopathy (1,2,10,12,19,20,24). The importance of venous drainage in the clinical presentation of DAVFs is well known when they distinguished between drainage directly into the dural sinuses and the pial veins(Table 1) (3,5,8).…”

Objective:Dural arteriovenous fistulas (DAVFs) is a complex condition in neurovascular surgery. Many DAVF classifications have been reported and have changed over time in the literatures. The purposes of this study was to propose a practical and easy-to-follow grading system for DAVFs.Methods: From a retrospective analysis of our database, 143 DAVF patients were consecutively collected. Patients were grouped into modified Borden types I, II and III. Patients’ characteristics, treatment and outcomes were analyzed between 3 types. Patients’ pre-treatment status(pre-mRS) were analyzed between Borden, Cognard and modified Borden grading systems. Results:Male and non-sinus locations were statistically significantly correlated with the type III DAVF type (p<0.001). More than 3 pedical suppliers and pial arterial suppliers were associated with high grade (type II and III) DAVFs(p=0.003). Worse symptoms were present in most type II and type III patients(p<0.001). Type III DAVF was associated with TAE and type II DAVF was associated with TVE treatment modalities(p<0.001). The results of one-way ANOVA indicated that pre-mRS was significantly different within modified Borden types and Cognard types (p = 4.3×10-6 and p = 1×10-4, respectively). In terms of pre-mRS, patients were not separated well using Cognard grading systems.Conclusions: A modified grading system of cerebral and spinal DAVFs was promoted according to understanding of angioarchitectures in order to evaluate risk of DAVFs and guide the therapies of these lesions. The modified Borden grading system was informative by providing an effective assessment for the risk of patients with simple but precise results.

“…It is very rare for DAVF to be the cause of HFS, and there have only been two reports thus far ( Table 1 ). 19 , 20) Deshmukh et al first described the association of HFS with a tentorial DAVF. 19) A 50-year-old man suffered from progressive left facial twitching.…”

“…Li et al reported of HFS associated with the dilated petrosal vein of the DAVF, which had compressed and indented the facial nerve at the REZ, and treated using transarterial Onyx embolization, and that post-embolization, the patient had a prompt improvement in the spasm. 20) Purely venous compression is rarely encountered. El Refaee et al reported that only one of 249 cases of facial spasms caused by venous compression.…”

Objective: We describe a patient treated with transarterial Onyx embolization for a tentorial dural arteriovenous fistula (DAVF) who presented with hemifacial spasm (HFS).Case Presentation: A 56-year-old man suffered from right blepharospasm for 4 years, and the symptom gradually spread to the right side of his face with oculo-oral synkinesis. MRI of the brain revealed abnormal multiple flow voids at the surface of brainstem and cerebellar hemisphere. MRA (time of flight) and spoiled gradient recalled echo-revealed abnormal vessels at the posterior fossa indicated arteriovenous shunting. 3D-MRI fusion images showed that a dilated vein was in contact with the root exit zone (REZ) of the right facial nerve. The right carotid angiography displayed a complex tentorial DAVF on the right side. There were multiple feeding vessels drained to the tentorial sinus at the point where the inferior cerebellar vermian vein met, and severe venous congestion was noted. We diagnosed a tentorial DAVF and thought that this was responsible for the right HFS. We used neuroendovascular treatment for this lesion. After transarterial Onyx embolization, his right HFS diminished. MRI after treatment showed that the vein in contact with the REZ of the right facial nerve had shrank. Conclusion:We experienced a rare case of HFS associated with a DAVF. Our case supports that transarterial Onyx embolization can treat HFS associated with a tentorial DAVF. It is the first description of successful treatment that could be confirmed through postoperative MRI.

“…HFS caused by cerebral aneurysms is reported to be rare. 1,2) For treatment of this type of HFS, clipping, endovascular treatment, and MVD have been reported. [3][4][5][6][7][8] However, many of these aneurysms were dissecting or fusiform aneurysms.…”

We report a rare case of symptomatic vertebral and posterior inferior cerebellar arteries (VA-PICA) aneurysmcaused ipsilateral hemifacial spasm (HFS) for which coil embolization of the aneurysm with the assistance of abnormal muscle response (AMR) monitoring was effective. Case Presentation: A 62-year-old woman presented with left HFS. Magnetic resonance imaging showed a saccular aneurysm of the left VA-PICA which compressed the seventh cranial nerve at its root exit zone (REZ). Stent-assisted coil embolization resulted in intraoperative disappearance of AMR in the intraoperative electrophysiological study and HFS was relieved temporally. One month after endovascular surgery, HFS slightly occurred again with the reappearance of the AMR, although there was no recurrence of aneurysm. Thereafter, the frequency of her HFS markedly decreased to once per several days 1 year after the coiling. Conclusion: Although complete disappearance of symptoms was not obtained, it was suggested that coil embolization is one of the therapeutic options for HFS which is caused by aneurysmal compression of REZ and intraoperative AMR is useful for identification of responsible lesions and determination of therapeutic effects. Keywords▶ hemifacial spasm, aneurysm, coil embolization, abnormal muscle response with assistance of abnormal muscle response (AMR) monitoring and showed the marked improvement in symptoms. Case Presentation A 62-year-old woman presented with HFS in her left eyelid, which appeared 3 years ago and progressively aggravated over the last 6 months to be persistent during the daytime. MRI revealed a left VA-PICA aneurysm, which was in the posterior upper direction, located near REZ of the facial nerve. Then we considered the cause of HFS was the aneurysm. Neurological findings: Her general condition was good and she had no neurological abnormality except for continuous HFS of the left eyelid which did not expand to the orbicularis oris muscle or platysma. Imaging findings: Computed tomography angiography (CTA) revealed that the left vertebral artery (VA) was tortuous and a saccular aneurysm of the left VA-PICA junction, projecting toward the posterior upper direction (Fig. 1A-1C). The aneurysm had a wide neck and its neck slightly rode on the posterior inferior cerebellar artery This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives International License.
