Surgical Treatment for Spinal Arteriovenous Malformation

In this paper, we outlined the diagnostic and treatment strategies for spinal arteriovenous malformations, focusing on dural and perimedullary arteriovenous fistula(AVF). In many patients with spinal arteriovenous malformations, the symptoms are non-specific. Therefore, we consider it is critical to detect the signal flow voids in the enlarged spinal veins using MRI. An accurate understanding of the vascular structures is indispensable for deciding appropriate treatment strategies. Hence, performing an angiography is essential. Regarding treatment, whether to select surgical or endovascular treatment for AVF depends largely on the institution's protocols. However, the treatment should always be based on an accurate diagnosis.
