Summary
Spinal dural arteriovenous fistulas cause leg weakness and bladder issues. Endovascular embolization successfully treated most patients, improving neurological deficits.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Context:
- Spinal dural arteriovenous fistulas (SDAVFs) are rare vascular malformations.
- They often present with progressive myelopathy, affecting motor and autonomic functions.
- Early diagnosis and treatment are crucial for better outcomes.
Purpose:
- To review clinical and neuroradiological findings in patients with SDAVF.
- To evaluate the efficacy of endovascular embolization for SDAVF treatment.
- To discuss the pathophysiology underlying the clinical manifestations of SDAVF.
Summary:
- This study reviewed 8 patients with SDAVF, noting progressive spastic paraparesis, and micturition/defecation disturbances as common symptoms.
- Diagnostic findings included elevated cerebrospinal fluid protein, dilated perimedullar veins on myelography, and intramedullary T2 signal changes on MRI.
- Endovascular embolization using N-butyl cyanoacrylate achieved successful treatment in 6 out of 8 patients, leading to significant improvement in leg weakness and partial recovery of autonomic functions.
Impact:
- Highlights the effectiveness of endovascular embolization as a primary treatment for SDAVF.
- Provides insights into the diagnostic utility of MRI and angiography in SDAVF.
- Contributes to understanding the pathophysiology and clinical presentation of SDAVF, aiding in timely diagnosis and management.
