ABSTRACT We present a rare case of multiple spinal perimedullary arteriovenous fistulae associated with the Parkes-Weber (PW) syndrome. A 31-year-old male known to have the PW syndrome involving the left leg since birth, presented with a 7-month-history of progressive myelopathy of the lower extremities and dysfunction of the bladder and bowel. Myelography demonstrated dilated intradural vessels. Angiography demonstrated two distinct single hole perimedullary arteriovenous fistulae near the conus at two different metameres. They were supplied by the left posterior spinal artery. The patient was treated by transarterial embolisation using polyvinyl alcohol particles, which resulted in venous side occlusion of the fistulae. After the treatment, the patient developed transient worsening of the spasticity of the lower extremities, and was treated by heparinization. After heparinization, the patient partially recovered from the pre-embolisation status of his myelopathy. The follow-up angiogram one year after the embolisation demonstrated persistent obliteration of both fistulae. At long-term follow-up, the patient can ambulate without assistance and work as a farmer.

    ABSTRACT: We describe a rare case of multiple arteriovenous fistulae of the spinal cord (SCAVF) in the same myelomer in a five-year-old boy. This case report consists of a trifocal SCAVF at the Th12 myelomeric level without communication between the three different fistulae. Two AVF were located posteriorly, bilateraly, in the spinal cord, fed by left and right posterior radiculopial arteries and one anteriorly in the anterior spinal axis. The venous drainage was independent for each lesion. The patient presents associated lesions characterized by cutaneous stain and inferior limb asymmetry. A metameric distribution is the explanation for the multiplicity of these lesions in a syndromic association related to Cobb syndrome. The patient was treated by transarterial embolization using glue with occlusion of the three different fistulae. The patient achieved a good improvement in neurological status.

    ABSTRACT: We describe a 24-year-old woman who presented with twice previously unverified subarachnoid hemorrhages from the conus medullaris spinal arteriovenous malformation with Parkes-Weber-syndrome. Spinal MRI examination is considered to be necessary for the diagnosis of Klippel-Trenaunay-Weber syndrome. For diagnosis of the spinal cord arteriovenous malformation, it is indispensable to search carefully for the presence of accompanying lesions. Transarterial glue embolizationis effective for the management of the spinal vascular lesion.
