Background: We reviewed the clinical outcomes of a procedure that combines endovascular embolization and a direct surgical approach in a hybrid operating room (OR) for the treatment of refractory dural arteriovenous fistulas (dAVFs). Methods: All patients with intracranial dAVFs who underwent a procedure combining endovascular embolization and direct surgical approach with biplane angiography or a robotic C-arm system in a hybrid OR between February 2004 and June 2020 were considered. Borden grading, occlusion rate, pre-and post-operative modified Rankin Scale (mRS) scores, and complications were retrospectively investigated. The pre-and postoperative mRS scores were compared using the Wilcoxon signed-ranks test. Results: We evaluated 14 arteriovenous fistulas (AVFs) in consecutive 13 patients. Of these, ten AVFs were previously treated with endovascular embolization, ten were located in the transverse-sigmoid sinus, and four in the cortical vein. The Borden grade was II in two AVFs and III in 12 AVFs. Immediate occlusion of the AVF was achieved in 13 AVFs, and gradual occlusion was observed in one case. The median preoperative mRS was 1 (0–3), whereas the median postoperative mRS was 0 (0–1) which indicated marked improvement (P = 0.006). Complications including postoperative transient visual disturbance and intraprocedural extravasation were observed in only two cases. Conclusion: The combination of endovascular embolization and direct surgical approach in a hybrid OR could achieve sufficient occlusion of refractory AVFs with acceptable complication rates and improved symptoms.

Endovascular embolization has evolved to become the primary therapeutic option for dural arteriovenous fistulas (DAVFs). While guaranteeing complete occlusion of the fistula orifice, the goal of DAVF embolization is also to ensure the patency of normal cerebral venous drainage. This paper describes a case of successful embolization of a complex DAVF in the superior sagittal sinus with a multistaged approach using a combination of transvenous and transarterial tactics. The strategies and techniques are discussed.

Spinal Arteriovenous Malformations

Spinal vascular malformations are rare, with dural arteriovenous fistulas (AVFs) accounting for the majority of the pathology. Unlike spinal arteriovenous malformations, which cause abrupt neurological change as a result of hemorrhage, spinal dural AVFs tend to result in a progressive myelopathy through venous congestion and cord edema. If diagnosed and treated early with endovascular embolization or microsurgery, some deficits may be reversible.

Abstract Anterior cranial fossa dural arteriovenous fistulas (DAVFs) are an infrequent subtype of cranial DAVFs. These lesions are most commonly derived from the ophthalmic artery. These lesions are often best treated utilizing endovascular embolization; however, this modality can be challenging because of the difficulty in catheterizing the ophthalmic or ethmoidal arteries. Surgical intervention is therefore indicated and requires approaching the proximal portion of the drainage vein to appropriately obliterate the fistulous point. For ethmoidal DAVFs, this is frequently along the dura of the cranial base adjacent to the cribriform plate. This patient had a right frontal hematoma with a typical ethmoidal DAVF. The fistula was exposed through a frontal craniotomy, and the ethmoidal branch was identified at the fistulous point. Intraoperative angiography was used to test for obliteration, which revealed a contralateral DAVF. The contralateral fistula was then obliterated in a similar manner, demonstrated on a second intraoperative angiogram. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.

OBJECTIVE Vascular malformations of the spine represent rare clinical entities with profound neurological implications. Previously reported studies on management strategies for spinal dural arteriovenous fistulas (sDAVFs) appeared before the advent of modern liquid embolic agents. Authors of the present study review their institutional experience with endovascularly and surgically treated sDAVFs. METHODS The authors performed a retrospective, observational, single-center case series on sDAVFs treated with endovascular embolization, microsurgical occlusion, or both between 2004 and 2013. The mode, efficacy, and clinical effect of treatment were evaluated. RESULTS Forty-seven patients with spinal arteriovenous malformations were evaluated using spinal angiography, which demonstrated 34 Type I sDAVFs (thoracic 20, lumbar 12, and cervical 2). Twenty-nine of the patients (85%) were male, and the median patient age was 63.3 years. Twenty patients underwent primary endovascular embolization (16 Onyx, 4 N-butyl cyanoacrylate [NBCA]), and 14 underwent primary surgical clipping. At a mean follow-up of 36 weeks, according to angiography or MR angiography, 5 patients treated with endovascular embolization demonstrated persistent arteriovenous shunting, whereas none of the surgically treated patients showed lesion persistence (p = 0.0237). Thirty patients (88%) experienced some resolution of their presenting symptoms (embolization 17 [85%], surgery 13 [93%], p = 1.00). CONCLUSIONS Microsurgical occlusion remains the most definitive treatment modality for sDAVFs, though modern endovascular techniques remain a viable option for the initial treatment of anatomically amenable lesions. Treatment of these lesions usually results in some clinical improvement.

Object Spinal dural arteriovenous fistulas (DAVFs) are the most common spinal vascular malformations and can be a significant cause of myelopathy, yet remain inefficiently diagnosed lesions. Over the last several decades, the treatment of spinal DAVFs has improved tremendously due to improvements in neuroimaging, microsurgical, and endovascular techniques. The aim of this paper was to review the existing literature regarding the clinical characteristics, classification, and endovascular management of spinal DAVFs. Methods A search of the PubMed database from the National Library of Medicine and reference lists of all relevant articles was conducted to identify all studies pertaining to spinal DAVFs, spinal dural fistulas, and spinal vascular malformations, with particular attention to endovascular management and outcomes. Results The ability to definitively treat spinal DAVFs using endovascular embolization has significantly improved over the last several decades. Overall rates of definitive embolization of spinal DAVFs have ranged between 25 and 100%, depending in part on the embolic agent used and the use of variable stiffness microcatheters. The majority of recent studies in which N-butyl cyanoacrylate or other liquid embolic agents were used have reported success rates of 70–90%. Surgical treatment remains the definitive option in cases of failed embolization, repeated recanalization, or lesions not amenable to embolization. Clinical outcomes have been comparable to surgical treatment when the fistula and draining vein remain persistently occluded. Improvements in gait and motor function are more likely following successful treatment, whereas micturition symptoms are less likely to improve. Conclusions Endovascular embolization is an increasingly effective therapy in the treatment of spinal DAVFs, and can be used as a definitive intervention in the majority of patients that undergo modern endovascular intervention. A multidisciplinary approach to the treatment of these lesions is required, as surgery is required for refractory cases or those not amenable to embolization. Newer embolic agents, such as Onyx, hold significant promise for future therapy, yet long-term follow-up studies are required.

Spinal Dural Arteriovenous Fistulas

Abstract: Spinal dural arteriovenous fistulas are a rare cause of congestive myelopathy. Symptoms are insidious in onset and may be confused with degenerative spinal disease. MRI characteristically shows edema of the spinal cord with serpiginous flow voids that follow the surface of the spinal cord. Careful evaluation with spinal angiography is required to ensure accurate diagnosis. Spinal dural arteriovenous fistulas differ from spinal arteriovenous malformations in that most fistulas have only a single fistulous point without a nidus. Spinal dural arteriovenous fistulas may be treated successfully with either surgical resection or endovascular embolization depending on their anatomy. Earlier treatment is associated with better outcomes.
