Vertebral arteriovenous fistulas: a study of 49 cases and review of the literature.
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 operated on and 33 had endovascular treatment. In nine patients who were either symptom-free or in poor health, no treatment was advised. The fistula was occluded in 38 (93%) of the treated patients, and the vertebral artery patency was preserved in 32 (78%). A total of 224 published cases were reviewed: 152 were traumatic, most after a penetrating injury; 72 were spontaneous, with three age peaks (at 7, 26 and 52 years). Treatment has evolved considerably and endovascular occlusion is now the treatment of choice, surgery being reserved for specific indications.
