Abstract

: Spinal dural arteriovenous fistulas (SDAVFs) are characterized by an abnormal connection between a spinal radicular artery and a perimedullary vein, mainly fed by a radicular artery at the nerve root sleeve. Here, we describe the case of a 40-year-old woman, presenting with progressive weakness of the lower extremities and the sphincter. Thoracic magnetic resonance imaging (MRI) showed spinal cord edema and signal voids on the dorsal surface of the cord. Spinal angiography demonstrated a SDAVF with a nidus at the sacral level; the feeder of the arteriovenous fistula was a lateral sacral artery, as a branch of the internal iliac artery. The lateral sacral artery was subselectively catheterized, and SDAVF was embolized with 25% n-butyl cyanoacrylate (NBCA) glue (glue: lipiodol ratio, 1:3). After embolization, no definite residual connection was visualized between the arterial and venous systems.

脊膜动静脉瘘的双侧骶管起源：一例报告

：硬脊膜动静脉瘘（SDAVFs）的特征是脊髓根动脉和髓周静脉之间的异常连接，主要由神经根套管处的根动脉供血。在这里，我们描述一位40岁的女性，表现为下肢和括约肌进行性无力。胸部磁共振成像（MRI）显示脊髓水肿和脊髓背表面的信号空洞。脊髓血管造影术显示SDAVF在骶骨水平有一个病灶；动静脉瘘的馈线是骶外侧动脉，作为髂内动脉的一个分支。对骶外侧动脉进行亚选择性插管，并用25%氰基丙烯酸正丁酯（NBCA）胶（胶：碘油比例，1:3）栓塞SDAVF。栓塞后，动脉和静脉系统之间没有明确的残余连接。

期刊介绍： The Iranian Journal of Radiology is the official journal of Tehran University of Medical Sciences and the Iranian Society of Radiology. It is a scientific forum dedicated primarily to the topics relevant to radiology and allied sciences of the developing countries, which have been neglected or have received little attention in the Western medical literature. This journal particularly welcomes manuscripts which deal with radiology and imaging from geographic regions wherein problems regarding economic, social, ethnic and cultural parameters affecting prevalence and course of the illness are taken into consideration. The Iranian Journal of Radiology has been launched in order to interchange information in the field of radiology and other related scientific spheres. In accordance with the objective of developing the scientific ability of the radiological population and other related scientific fields, this journal publishes research articles, evidence-based review articles, and case reports focused on regional tropics. Iranian Journal of Radiology operates in agreement with the below principles in compliance with continuous quality improvement: 1-Increasing the satisfaction of the readers, authors, staff, and co-workers. 2-Improving the scientific content and appearance of the journal. 3-Advancing the scientific validity of the journal both nationally and internationally. Such basics are accomplished only by aggregative effort and reciprocity of the radiological population and related sciences, authorities, and staff of the journal.
