13 patients with spinal dural arteriovenous fistulas (DAVF) diagnosed in our Institution have been the object of this study. The necessity to include the disease in the differential diagnosis with other pathologies affecting the lower thoracic cord, particularly in middle-aged and old males, is emphasized. Involvement of the spinal cord was always demonstrable on magnetic resonance studies, but pathologic vessels suggesting the possibility of DAVF were seldom recognizable. Myelography still remains an important complementary method. Spinal angiography is essential, taking into account that the fistula can be located far from the spinal cord. The therapy consisting in embolization in 7 cases and embolization associated with surgery in 6 cases led to improvement or stabilization of the disease in all cases. Our cases are discussed in comparison with the literature.
本研究以在我院确诊的13例脊髓硬脊膜动静脉瘘（DAVF）患者为对象。强调了在鉴别诊断中需将该病与影响下胸段脊髓的其他病变相鉴别，尤其对于中老年男性患者。磁共振成像研究总能显示脊髓受累情况，但提示DAVF可能性的病变血管很少能被识别。脊髓造影仍是一种重要的辅助检查方法。考虑到瘘口可能位于远离脊髓的部位，脊髓血管造影必不可少。7例行栓塞治疗，6例行栓塞联合手术治疗，所有病例病情均得到改善或稳定。我们将结合文献对这些病例进行讨论。
