Spinal Arteriovenous Malformation Associated with a Radicular Arteriovenous Fistula Suggested a Metameric Disease

A spinal intramedullary arteriovenous malformation (AVM) associated with a radicular arteriovenous fistula (AVF) is reported. The patient had mild myelopathy and low back pain. Spinal angiography revealed the AVM fed by the anterior spinal artery via left T10, T11 and right L1 radiculomedullary arteries and the radiculopial arteries of left L1, L2 and right T11, L3 levels and the radicular AVF at the left L4 level. There were three radiculomedullary arteries within four levels in our case. This spinal AVM associated with a radicular AVF is considered a genetic nonhereditary lesion with metameric link.

Spinal Dural Arteriovenous Fistula

Introduction: Low back pain or numbness of the lower extremities is quite common in the present population. Numerous conditions may cause these symptoms, including spinal vascular anomaly. Identifying and diagnosing the cause of these symptoms are crucial for treatment. Accurate diagnosis based on particular radiological findings in magnetic resonance imaging is crucial for administering adequate therapy to patients, especially in spinal dural arteriovenous fistula. Case presentation: We report a case presenting with low back pain and rapid deterioration in paraplegia. Magnetic resonance imaging provided the typical image presentations such as spinal cord edema with tortuous dilated perimedullary venous plexus. The patient was subsequently successfully treated with endovascular embolization. Discussion: Spinal dural arteriovenous fistula should be suspected in any patient who presents with myelopathy. Angiography remains the gold standard for confirmation of diagnosis. Conclusion: Prompt treatment with endovascular embolization or surgery could improve patients’ outcomes.

✓ The authors report a patient in whom a subdural hematoma developed from a Type I spinal arteriovenous malformation (AVM). The patient became symptomatic with back pain, and magnetic resonance imaging revealed a spinal subdural hematoma. Selective spinal angiography, however, failed to demonstrate a pathological process. The patient underwent exploratory laminoplasty that revealed a subdural extraarachnoid hematoma with an underlying Type I spinal AVM, which was surgically obliterated. The patient recovered completely. Subdural hematomas that affect the spine are rare. Although a negative result was obtained using selective spinal angiography, exploratory surgery should be considered for the evacuation of a subdural hematoma and possibly for the definitive treatment of a spinal AVM.
