Spinal Vascular Malformations

Type 1 spinal dural arteriovenous fistula (dAVF) constitute the vast majority of all spinal vascular malformations. Here we present the case of a 71-year-old male with progressive myelopathy, lower-extremity weakness and numbness, and urinary incontinence. MRI imaging of the thoracic spine demonstrated cord edema, and catheter spinal angiography confirmed a type 1 spinal dAVF. The fistula was supplied by small dural branches of the left L-2 segmental artery. Angiographic cure was achieved with a one-stage procedure in which coils were used to occlude the distal segmental vessels, followed by balloon-assisted embolization with Onyx.The video can be found here: http://youtu.be/8aehJbueH0U.

Spinal Cord Volume

ObjectivesTo examine the utility of standardised volumetric spinal cord measurement as an indicator of successful disconnection of a Type 1 spinal dural arteriovenous fistula.DesignRetrospective analysis at a tertiary neuroscience centre.SubjectsPatients with symptomatic Type 1 spinal dAVFs presenting to the senior author and neurovascular MDT (June 2009 – December 2017). Inclusion based on availability of appropriate cross-sectional imaging. DAVFs arising below T12 excluded: 18 patients with a total 19 dAVFs identified.MethodsType 1 fistulation demonstrated on TRICKS MR angiography and spinal catheter angiography. Sagittal volumes evaluated using Horos (Purview, Annapolis, USA) and wireframe models created. Measurement arbitrarily standardised at ±2 levels from the origin of the fistulous draining vein. Pre- and post-operative clinical outcomes assessed using the Aminoff-Logue Scale. Wilcoxon test employed for between-group comparisons and Spearman’s rank test for clinico-radiological correlation (Prism 7, GraphPad Software, Inc. California).ResultsCord volumes reduced by a mean of 0.854 cm3 (p=0.0181; 95% CI=−1.55,–0.16; SD=1.44). Volume change was not related to gait (r=0.037, p=0.8812, 95% CI=−0.44, 0.49) or micturition scores (r=−0.24, p=0.3165, 95% CI=−0.64, 0.25).ConclusionsSurgical disconnection of type 1 dAVF resulted in a reduction in spinal cord volume. This was not predictive of change in clinical indices in this small series but perhaps merits investigation of this as a surrogate marker in a larger series.

Low Rate

Spinal dural arteriovenous (AV) fistulas are the most commonly encountered vascular malformation of the spinal cord and a treatable cause for progressive paraplegia or tetraplegia. They most commonly affected are elderly men and are classically found in the thoracolumbar region.Symptoms gradually progress or decline in a stepwise manner and are commonly associated with pain and sphincter disturbances. Surgical or endovascular disconnection of the fistula has a high success rate with a low rate of morbidity. Motor symptoms are most likely to improve after treatment, followed by sensory disturbances, and lastly sphincter disturbances.

Background/objectiveThe concomitant origin of the anterior spinal artery (ASA) or the posterior spinal artery (PSA) from the feeder of a spinal dural arteriovenous fistula (SDAVF) is rare and the exact incidence is not known. We present our experience with the management of SDAVFs in such cases.MethodsIn 63 patients with SDAVF between 1993 and 2015, the feeder origin of the SDAVF was evaluated to determine whether it was concomitant with the origin of the ASA or PSA. Embolization was attempted when the patient did not want open surgery and an endovascular approach was regarded as safe and possible. The outcome of the procedure was evaluated as complete, partial, or no obliteration. The clinical outcome was evaluated by Aminoff–Logue (ALS) gait and micturition scale scores.ResultsNine patients (14%) had a concomitant origin of the ASA or PSA with the feeder. There were two cervical, five thoracic, and two lumbar level SDAVFs. A concomitant origin of the feeder was identified with the ASA (n=7) and PSA (n=2). Embolization was performed in four patients and open surgery was performed in five. Embolization resulted in complete obliteration in three patients and partial obliteration in one. Using the ALS gait and micturition scale, the final outcome improved in six while three cases remained in an unchanged condition over 2–148 months.ConclusionsThe concomitant origin of the ASA or PSA with the feeder occurs occasionally. Complete obliteration of the fistula can be achieved either by embolization or open surgery. Embolization can be carefully performed in selected patients who are in a poor condition and do not want to undergo open surgery.

The Impact

BackgroundThe preoperative localization of the feeder of spinal dural arteriovenous fistula (SDAVF) could simplify the diagnostic spinal angiographic procedure. Localization by non-contrast-enhanced MRI-based techniques is an attractive option. However, the usefulness of such an approach for evaluation of SDAVF has not yet been reported.ObjectiveTo study the impact of non-contrast MRI-based feeder localization, followed by targeted spinal angiography, in the evaluation of SDAVF before endovascular intervention.Materials and methodsProspectively collected data were analyzed and the level of the feeder was localized preoperatively. The procedural time for targeted spinal angiography was calculated and compared with that of a historical cohort, who underwent routine spinal angiographic examination before the study period. Follow-up MRI was carried out to assess the reliability of this model for detection of occasional metachronous lesions that might be missed with this approach.ResultsSeven patients underwent targeted spinal angiography during the study. The feeder level was accurately identified in five patients and was localized to one vertebral level in six patients. The correlation between MRI and DSA was statistically significant. The number of spinal levels assessed was fewer and overall procedure time was significantly shorter compared to historical cohort (58 min vs 162 min, respectively; p<0.001). Intervention was coupled with targeted angiography in two patients. Follow-up MRI demonstrated flow voids in one patient, who had recurrent fistula at one vertebral level below the previously embolized feeder.ConclusionsThe non-contrast MRI-based localization technique can reliably detect the level of feeder and help in therapeutic planning of SDAVF. The localization techniques potentially shorten the angiographic procedure and may facilitate simultaneous endovascular definitive treatment. Inclusion of follow-up MRI may be useful for detection of synchronous or metachronous lesions if a targeted approach is adopted. Additionally, this helps to identify failed endovascular therapy.
