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)
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 experience is reported with 50 vertebral fistulas treated by the authors in a joint radiological and surgical team. Of the 28 fistulas that were traumatic, 18 occurred after incidental iatrogenic puncture, and 22 were spontaneous, of which four presented in patients displaying angiographic features of fibromuscular dysplasia. Eleven patients were(More)
During the past 10 years, 25 infants with alarming hemangiomas--lesions that impaired important functions and were life threatening, especially when there was visceral involvement--have been treated. A vascular mark was present at birth in 68% of these infants. Visceral hemangiomas were associated with bulky cervicocephalic hemangiomas or with small(More)
Haemangiomas of the mandible are relatively rare arteriovenous malformations: 85 cases have been described since 1849. The severe risk of bleeding during tooth extraction or biopsy led us to describe the radiological and angiographic features of this condition. The afferent vessels are the inferior dental, the lingual, and the facial arteries. Preoperative(More)
The clinical and angiographic features of 46 vertebral arteriovenous fistulas (AVFs) seen during a 12-year period (45 patients) were reviewed. Fourteen patients were asymptomatic, with vertebral AVF discovered at routine clinical examination. Specific symptoms at presentation in the other patients were tinnitus (n = 21), vertigo (n = 6), neurologic deficit(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)
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)
