“…Regarding the progress after successful embolization, the patients usually feel better about their legs on the day after recovery from general anesthesia. 3,[10][11][12][13][14][15] They say the legs are light (not heavy as before). And then sensory and motor deficits slowly improve over the next few days.…”

“…5 In contrast, SDAVF is fed by a feeder in most cases and located dorsally within the dural sleeve between the radiculomeningeal artery and radicular or bridging veins without forming a dilated epidural venous sac. [10][11][12] The main goal of treatment is to alleviate neurological symptoms caused by venous congestive myelopathy by occluding the epidural venous pouch or the culprit vein that causes intradural reflux. 1 Endovascular treatment with a transarterial approach can be performed if the arterial feeders supplying a small epidural venous sac have a relatively straight course, especially in the non-osseous type of SE-DAVF.…”

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.

“…11,12 Such crosses may be possible either through the isolated cortical vein (caused by reasons like thrombosis or adhesion in the cortical vein) or other channels (like the emissary-bridging vein, which does not drain into the cortical vein in the subarachnoid space and does drain directly into the venous sinus or the extradural vein via certain trans-dural segments, as in the spinal DAVF). 13 Such dural shunts with the direct pial venous reflux seem to be observed at the overlapped border of the primary meninx forming meninges and calvaria, which are separately originated from the neural crest in meninges, and mesoderm in calvaria, as in the areas like the parietal convexity. 3,14…”
