Forty-three patients with arterio-venous fistulae of the dura of the transverse sinus with a complaint of tinnitus are reviewed, with a follow-up of 12 months to 11 years. 34 patients were embolized, 2 treated surgically, and 7 were untreated. Embolization appears to have been beneficial. The frequently benign nature of this abnormality must be emphasized,(More)
During a 3 year period, 21 patients with spinal cord vascular malformations involving the anterior spinal artery were treated by embolization through this artery. Of four cases of extramedullary arteriovenous fistula, two patients embolized at an early stage showed excellent results, whereas results were mediocre in two patients who were paraplegic at(More)
The cases of 38 children with AVM seen at the Lariboisière Hospital since 1962 are reviewed. The clinical picture was often of sudden onset with impairment of motor function and/or subarachnoid hemorrhage. The diagnosis was usually made by myelography, but spinal arteriography is the key examination, since it confirms the diagnosis and is essential to(More)
We studied eleven patients with intrathecal extramedullary arteriovenous fistulas identified by selective angiography and myelography. The fistulas were located on the surface of the cord, fed by medullary arteries. Angiography distinguished three separate types that gave identical clinical disorders. Therapeutic results of surgery and embolization allowed(More)
A case of a large extramedullary arteriovenous fistula in a young man, which was deemed inoperable, is described. The fistula was mainly supplied by the anterior spinal artery and was responsible for a progressive myeloradicular syndrome. Successful treatment with detachable balloons was carried out. Along with this case report, a review is made of the(More)
Thirty-four patients with angiographically proved arteriovenous malformations of the spinal cord were studied between May 1986 and July 1987. Examinations were performed on a CGR 5000 Magniscan 0.5-T scanner with a surface coil in all cases, and multislices in both T1- and T2-weighted sequences were obtained in sagittal and axial planes. The results showed(More)
