Spinal Dural Arteriovenous Fistulas: A Rare, Insidious Cause of Progressive Myelopathy
نویسندگان
چکیده
Spinal Dural Arteriovenous fistulas (sDAVFs) represent the most common vascular malformation of the spinal cord accounting for 70% of all cases and are very rare in the general population. Usually, sDAVFs present with symptoms and signs of myelopathy and if left untreated can lead to permanent disability. The diagnosis and characterization of sDAVFs requires high index of suspicion and knowledge of the vascular supply and venous drainage of the spinal cord. The present review highlights the most important pathophysiologic characteristics, clinical findings, diagnostic modalities and treatment options available for spinal DAVFs.

CASE REPORT Double Spinal Dural Arteriovenous Fistulas
A. El-Serwi A. Maubon J. Vidal R. Chapot SUMMARY: We present a patient with double spinal dural arteriovenous fistulas revealed by progressive myelopathy. Numerous dilated veins extending along the entire length of the spinal cord were found on MR imaging. Angiography showed a first spinal dural fistula at the level of T7 with descending venous drainage and a second spinal dural fistula at the ...

The spinal dural arteriovenous fistula (SDAVF) is rare, presenting with progressive, insidious symptoms, and inducing spinal cord ischemia and myelopathy, resulting in severe neurological deficits. If physicians have accurate and enough information about vascular anatomy and hemodynamics, they achieve the good results though the surgery or endovascular embolization. However, when selective spin...

Spinal vascular malformations (SVM) are rare diseases in comparison to vascular malforma‐ tions of the brain. Spinal dural arteriovenous fistulas (SDAVFs), also known as Type I spinal arteriovenous malformations, account for 70% of spinal vascular malformations, and are the most common vascular malformations of the spinal cord and its surrounding dura mater; however, they remain relatively unde...

PURPOSE To examine the clinical and radiographic findings in a large group of patients having or suspected of having a spinal dural arteriovenous fistula. METHODS An analysis of 240 spinal angiograms in 132 patients revealed 97 vascular malformations that included 66 spinal dural arteriovenous fistulas. Sixteen patients had 1 or more normal spinal angiograms that were performed for suspected ...
متن کاملPredictive Factors of the Management of Spinal Cord Arteriovenous Fistulas.
AIM Spinal cord arteriovenous fistulas are rare cause of progressive myelopathy. The predictive factors of their outcome after endovascular or surgical treatment are still controversial. MATERIAL AND METHODS Twenty patients were diagnosed with spinal arteriovenous fistulas; 13 of them had dural and 7 had perimedullary fistulas (1 Dorsal and 6 Ventral). Surgery, endovascular or both treatments...
