Abstract

Background: Spinal dural arteriovenous fistulae comprise the majority of spinal vascular malformations. The most common clinical presentation is thatof progressive myeloradiculopathy, probably related to venous hypertension, which may lead to permanent disability and even death. Objective: To report our clinical experience with spinal dural arteriovenous fistulae. Methods: Nine patients with spinal dural AVF were managed at our center during a one year period (1998-1999). The patients, eight men and one woman ranging in age from 46 to 75 years, presented with initially fluctuating andeventually permanent and progressive paraparesis, sensory disturbances andsphincter dysfunction. The neurological signs generally began symmetrically and progressed from the distal to proximal limb regions. The duration of symptoms before diagnosis ranged from 6 to 36 months during which the patents underwent an extensive but fruitless work-up and even unnecessary operations due to misdiagnosis. All patients finally underwent magnetic resonanceimaging and spinal angiography, which demonstrated the pathological vascular fistula. Interruption of the AVF was achieved by embolization or by surgical resection. Results: Following treatment, six patients experienced improvement of gaitand sphincter control, and the severe neurological deficits stabilized in the other three patents with long duration of illness. There was no furtherdeterioration in any of the treated patients. Conclusions: The history, neurological findings and radiological changes on MRI scan should alert clinicians to the possibility of spinal dural AVF, leading to diagnostic spinal angiography. Early diagnosis and treatment maysignificantly improve outcome and prevent permanent disability and even mortality.
