“…An operation was a good alternative in this patient, and symptoms improved as in patients with SDAVFs. 17 The vascular structures surrounding the lesion must be analyzed thoroughly to determine appropriate treatment plans. We routinely obtain a 3D rotational spinal angiogram to better understand the relationships among the feeders, fistulas, and draining veins.…”

BACKGROUND AND PURPOSE: Spinal epidural arteriovenous fistulas are rare vascular malformations. We present 13 patients with spinal epidural arteriovenous fistulas, noting the various presenting symptom patterns, imaging findings related to bone involvement, and outcomes. MATERIALS AND METHODS:Among 111 patients with spinal vascular malformations in the institutional data base from 1993 to 2017, thirteen patients (11.7%) had spinal epidural arteriovenous fistulas. We evaluated presenting symptoms and imaging findings, including bone involvement and mode of treatment. To assess the treatment outcome, we compared initial and follow-up clinical status using the modified Aminoff and Logue Scale of Disability and the modified Rankin Scale. RESULTS:The presenting symptoms were lower back pain (n ϭ 2), radiculopathy (n ϭ 5), and myelopathy (n ϭ 7). There is overlap of symptoms in 1 patient (No. 11). Distribution of spinal epidural arteriovenous fistulas was cervical (n ϭ 3), thoracic (n ϭ 2), lumbar (n ϭ 6), and sacral (n ϭ 2). Intradural venous reflux was identified in 7 patients with congestive venous myelopathy. The fistulas were successfully treated in all patients who underwent treatment (endovascular embolization, n ϭ 10; operation, n ϭ 1) except 2 patients who refused treatment due to tolerable symptoms. Transarterial glue (n ϭ 7) was used in nonosseous types; and transvenous coils (n ϭ 3), in osseous type. After 19 months of median follow-up, the patients showed symptom improvement after treatment. CONCLUSIONS:Although presenting symptoms were diverse, myelopathy caused by intradural venous reflux was the main target of treatment. Endovascular treatment was considered via an arterial approach in nonosseous types and via a venous approach in osseous types.ABBREVIATIONS: ALS ϭ Aminoff and Logue Scale of Disability; SDAVF ϭ spinal dural arteriovenous fistula; SEDAVF ϭ spinal epidural arteriovenous fistula; TAE ϭ transarterial embolization; TVE ϭ transvenous embolization

The cervical anterior spinal artery (ASA) is a very important artery arising from the intracranial vertebral artery (VA). It can play different roles in endovascular treatment (EVT) of spinal vascular diseases. The current understanding of these roles is incomplete; therefore, we performed this review. We found that cervical ASA can be involved in many spinal vascular diseases, such as arteriovenous fistula (AVF), arteriovenous malformation (AVM), and aneurysm, and can serve as a collateral channel in proximal VA occlusion. In AVF and AVM, when the cervical ASA is involved, it often plays the role of an accomplice or victim because it acts as the feeder or as a bystander that does not provide blood flow to the AVF and AVM. In cervical ASA aneurysm, the ASA is a victim. During EVT of VA aneurysms or stenoses, the cervical ASA ostia can be covered or occluded, resulting in ASA ischemia. In this situation, the ASA is a victim. In VA occlusion or the subclavian steal phenomenon, the cervical ASA can serve as a collateral channel to provide blood flow to the posterior circulation. In this case, the ASA plays the role of a friend. According to the role of the cervical ASA in spinal vascular diseases, EVT should be determined “case by case.” Most importantly, when EVT is performed to treat these diseases, the cervical ASA axis must be preserved. Therefore, understanding the role of the cervical ASA in spinal vascular diseases is crucial.

“…Digital subtraction spinal angiography (Artis zee; Siemens, Forchheim, Germany) with selective angiography or 3-dimensional rotational angiography (3DRA) was used for localization and characterization of the SEDAVF, including the relationship between feeding arteries, epidural venous sacs, epidural venous drainage, and the point of intradural reflux and the venous drainage pattern. 2,18,19 Spinal magnetic resonance imaging (MRI) was performed for the initial assessment of the disease. Axial and sagittal images of T1-and T2-weighted sequences with or without contrast enhancement were obtained with 1.5T or 3T systems.…”

Purpose: Spinal epidural arteriovenous fistulas (SEDAVFs) show an epidural venous sac often with venous congestive myelopathy (VCM) due to intradural reflux at a remote level to which a transarterial approach would be difficult. We present 12 cases of SEDAVF with VCM and describe 3 main tactics for effective transarterial embolization.Materials and Methods: Among 152 patients with spinal vascular malformations diagnosed in our tertiary hospital between 1993 and 2019, 12 SEDAVF patients with VCM were included. Three different transarterial embolization tactics were applied according to the vascular configuration and microcatheter accessibility. We evaluated treatment results and clinical outcomes before and after treatment.Results: Transarterial embolization with glue (20–30%) was performed in all patients. The embolization tactics applied in 12 patients were preferential flow (n=2), plug-and-push (n=6), and filling of the venous sac (n=4). Total occlusion of the SEDAVF, including intradural reflux, was achieved in 11 (91.7%) of 12 patients, and partial occlusion was achieved in 1 patient. No periprocedural complications were reported. Spinal cord edema was improved in all patients for an average of 18 months after treatment. Clinical functional outcome in terms of the pain, sensory, motor, and sphincter scale and modified Rankin scores improved during a mean 25-month follow-up (6.3 vs. 3.3, P=0.002; 3.6 vs. 2.3, P=0.002, respectively).Conclusion: Endovascular treatment for 12 SEDAVF patients with VCM achieved a total occlusion rate of 91.7% without any periprocedural complication. The combined embolization tactics can block intradural reflux causing VCM, resulting in overall good clinical outcomes.
