Progressive Weakness

: Spinal dural arteriovenous fistulas (SDAVFs) are characterized by an abnormal connection between a spinal radicular artery and a perimedullary vein, mainly fed by a radicular artery at the nerve root sleeve. Here, we describe the case of a 40-year-old woman, presenting with progressive weakness of the lower extremities and the sphincter. Thoracic magnetic resonance imaging (MRI) showed spinal cord edema and signal voids on the dorsal surface of the cord. Spinal angiography demonstrated a SDAVF with a nidus at the sacral level; the feeder of the arteriovenous fistula was a lateral sacral artery, as a branch of the internal iliac artery. The lateral sacral artery was subselectively catheterized, and SDAVF was embolized with 25% n-butyl cyanoacrylate (NBCA) glue (glue: lipiodol ratio, 1:3). After embolization, no definite residual connection was visualized between the arterial and venous systems.

Spinal Dural Arteriovenous Fistulas

Abstract Spinal dural arteriovenous fistulas are the most common vascular malformations of the spine. They are localized in the sacral spine in 5% to 14% of the cases. They can be fed by the median or the lateral sacral arteries. These lesions present with nonspecific symptoms such as radiculopathy and/or myelopathy, which often leads to a delay in diagnosis. In this video, we present the case of a 65-yr-old gentleman with a lateral sacral dural arteriovenous fistula. The patient was referred to our institution after the outside facility workup was nondiagnostic. He presented with spastic paraparesis and bilateral radiculopathy. After patient informed consent was obtained, we performed a spinal diagnostic angiogram with catheterization and angiography of the internal iliac artery, which revealed the fistula. Onyx (Medtronic, Dublin, Ireland) embolization was performed, which led to a complete occlusion of the fistula. The patient had complete neurological recovery, and at 2-yr follow-up, imaging remained negative for a fistula. In this video, we discuss the nuances and key points related to the epidemiology, diagnosis, and treatment of lateral sacral fistulas.1-3
