SUMMARY:During the past few decades, there have been significant advances in the understanding of spinal vascular lesions, mainly because of the evolution of imaging technology and selective spinal angiography techniques. In this article, we discuss the classification, pathophysiology, and clinical manifestations of spinal vascular lesions other than DAVFs and provide a review of the endovascular approach to treat these lesions.
ABBREVIATIONS:ASA ϭ anterior spinal artery; AVF ϭ arteriovenous fistula; AVM ϭ arteriovenous malformation; DAVF ϭ dural arteriovenous fistula; MMA ϭ middle meningeal artery; n-BCA ϭ n-butyl 2-cyanoacrylate; PSA ϭ posterior spinal artery; PVA ϭ polyvinyl alcohol; SAH ϭ subarachnoid hemorrhage; SVM ϭ spinal vascular malformation S pinal arteriovenous lesions are rare entities, with severe consequences if untreated. During the past few decades, there have been significant advances in the understanding of these lesions, mainly because of selective spinal angiography. Increased knowledge of the angioarchitecture and pathophysiology of SVMs has lead to the development of endovascular embolization for these lesions, first described by Dr Djindjian in France and Drs DiChiro and Doppman in the United States. Further evolution in imaging technology and interventional and surgical techniques allows us to manage these lesions more efficiently, in the context of a multidisciplinary approach. In this article, we present the classification and pathophysiology of spinal arteriovenous lesions and the approach to endovascular treatment. This article does not discuss the pathophysiology and management of spinal DAVFs, which was discussed in a prior review article in this journal.
