Abstract:
Objective To investigate the clinical effect of endovascular embolization in treating spinal dural arteriovenous fistulae, and to discuss its imaging manifestations. Methods A total of 7 patients with spinal dural arteriovenous fistulae were included in this study. Endovascular embolization was carried out in all the 7 patients. The clinical data, including epidemiology, spinal MRI and DSA manifestations, therapeutic method and follow-up findings, were retrospectively analyzed. Results Abnormal MRI manifestations of spinal cord were demonstrated in all 7 patients. After the diagnosis was confirmed by DSA, endovascular embolization was carried out. All patients were followed up for 6 months, and their clinical symptoms were improved in different degrees. N-butyl cyanoacrylate (NBCA) glue was used as embolization agent in 4 cases, and no recurrence was observed in them. Onyx liquid glue was used in 3 patients, and in one of them the arteriovenous fistula recurred. Conclusion For the treatment of spinal dural arteriovenous fistulae, endovascular embolization is effective and safe although further investigation is still needed.
