Spinal Arteriovenous Malformations: Radiological Findings and Classification
1Ege Üniversitesi Tıp Fakültesi, Radyoloji Anabilim Dalı, İzmir, Türkiye
Spinal vascular malformations are a rare group of neurovascular diseases with an insidious onset and progressive course that
can confine patients to a wheelchair within a few years if untreated. Over the years, with the maturation of angiographic vascular
anatomy knowledge, the accumulation of surgical experience, and, above all, the development of catheter and embolization
technology, superselective spinal angiography has made it possible to successfully treat many patients with a spinal vascular
malformation. The biggest problem for these patients is that the disease may not be considered in the clinical and radiological
differential diagnosis, and the diagnosis and hence the treatment is delayed. In this article, the pathophysiology, classification and
predominantly radiological findings of spinal vascular malformations will be discussed. Spinal vascular malformations should be
kept in mind in the differential diagnosis of patients with progressive paraparesis and sphincter dysfunction.
