ABSTRACT

INTRODUCTION Spinal dural arteriovenous fistulas (AVFs) frequently cause progressive myelopathy. Although endovascular approaches to spinal cord vascular malformations become an important adjunct or primary treatment of theses disorders, surgery can be safely performing in some categories. CASE REPORTS. Two males patients presented with progressively myelopathy two months and three years before, were diagnosed by typical MRI findings and spinal selective arteriograms of dorsal AVFs with single feeder of Spetzler’s modified classification of spinal cord vascular lesions. After an attempt of embolization following diagnostic angiography in first case, surgical approach for clipping the afferent single feeder was done for both.

CONCLUSIONS Early recognition by selective diagnostic spinal angiography in patients with slowly progressive and fluctuating myelopathy, allow us surgery as recommended treatment in AVFs, so can effect a better outcome and often reverse presenting neurologic deficits.
