Spinal Dural Arteriovenous Fistulas

Spinal dural arteriovenous fistulas are diagnostically challenging lesions, and they are not well described in patients with a history of a spinal deformity correction. The authors present the challenging case of a 74-year-old woman who had previously undergone correction of a spinal deformity with subsequent revision. Several years after the last deformity operation, she developed a progressive myelopathy with urinary incontinence over a 6-month period. After evaluation at the authors’ institution, an angiogram was obtained, demonstrating a fistula at the T12–L1 region. Surgical ligation of the fistula was performed with subsequent improvement of the neurological symptoms. This case is thought to represent the first fistula documented in an area of the spine that had previously been operated on, and to the authors’ knowledge, it is the first case report to be associated with spinal deformity surgery. A brief historical overview and review of the pathophysiology of spinal dural arteriovenous fistulas is also included.

Spinal Dural Arteriovenous Fistulas

Abstract: Spinal dural arteriovenous fistulas are a rare cause of congestive myelopathy. Symptoms are insidious in onset and may be confused with degenerative spinal disease. MRI characteristically shows edema of the spinal cord with serpiginous flow voids that follow the surface of the spinal cord. Careful evaluation with spinal angiography is required to ensure accurate diagnosis. Spinal dural arteriovenous fistulas differ from spinal arteriovenous malformations in that most fistulas have only a single fistulous point without a nidus. Spinal dural arteriovenous fistulas may be treated successfully with either surgical resection or endovascular embolization depending on their anatomy. Earlier treatment is associated with better outcomes.

Spinal Dural Arteriovenous Fistulas

Spinal dural arteriovenous fistula (DAVF) is an uncommon condition that can be difficult to diagnose. This often results in misdiagnosis and treatment delay. Although conventional MRI plays an important role in the initial screening for the disease, the typical MRI findings may be absent. In this article, the authors present a series of 4 cases involving patients with angiographically proven spinal DAVFs who demonstrated cord T2 prolongation on conventional MRI but without abnormal subarachnoid flow voids or enhancement. These cases suggest that spinal DAVF cannot be excluded in symptomatic patients with cord edema based on conventional MRI findings alone. Dynamic Gd-enhanced MR angiography (MRA) was successful in demonstrating abnormal spinal vasculature in all 4 cases. This limited experience provides support for the role of spinal MRA in patients with abnormal cord signal and symptoms suggestive of DAVF even when typical MRI findings of a DAVF are absent.

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.

The aim of this study is to review the clinical outcome of patients treated for spinal dural arteriovenous malformations and investigate the presence of pretreatment indicators of outcome after short- and midterm follow-up. The authors retrospectively reviewed the records of 65 consecutive patients treated either surgically or endovascularly in 3 neurosurgery departments between 1989 and 2009. After treatment, 80% of patients reported improvement of at least 1 symptom. Motor symptoms improved more than sensory disorders, pain, or sphincter impairment. Spinal dural arteriovenous fistulas at the thoracic level, and in particular at the lower level, responded better than those in other spinal areas. Spinal dural arteriovenous fistula is a rare pathology with a malignant course that should be treated aggressively. This study appears to confirm that neurological status before treatment, anatomical location of the fistula, and symptoms at presentation are all factors that can predict outcome. Early diagnosis of spinal dural arteriovenous malformations in the lower thoracic area in patients with an Aminoff scale score < 3 was associated with the most favorable outcome.

Spinal Dural Arteriovenous Fistulas

Spinal dural arteriovenous fistulas are rare and often unrecognized,  they occur predominantly in men, with an initial clinical picture most often  misleading made of chronic myelopathy in the absence of treatment, the evolution is slowly towards a definitive paraplegia. We report the case of a patient referred for a table of spinal cord compression revealing a spinal dural fistula with perimedullary venous drainage treated urgently, due to the worsening of the clinical picture. The standard treatment consists of surgical or endovascular exclusion of the fistula (in our case the fistula was surgically excluded). From this case and based on the literature, we will specify the a, clinical, radiological characteristics as well as the prognosis of these malformations, and we will discuss the possibilities of therapeutic management.

Spinal dural arteriovenous fistulas (SDAVFs) are often misdiagnosed as their symptoms are non-specific, leading to treatment delay and a poor outcome. We describe the case of a 53-year-old man with a history of progressive paraparesis that worsened abruptly after an epidural corticosteroid injection. We highlight here the need for high diagnostic suspicion for an SDAVF in patients deteriorating after an epidural injection and an indication of repeated spine imaging in such cases. Finally, this is the first reported case of an SDAVF in a HIV-positive patient and it emphasizes the need for a broad differential diagnosis.
