Abstract：Objective To study the clinical features,diagnosis and treatment measures of spinal dural arteriovenous fistula (SDAVF) at the atlanto-occipital junction.Methods Clinical data of 8 patients with SDAVF at the atlanto-occipital junction were analyzed retrospectively.Acute onset was found in 6 patients because of subarachnoid hemorrhage and chronic onset in 2 who showed sensorimotor dysfunction.Microsurgical clipping was performed on 7 patients and interventional embolization on 1 with bilateral SDAVF.Results Postoperative angiography showed all fistulas disappeared in 7 patients who received clipping.One side fistula embolization was achieved in 1 patient who received embolization.Eight patients were followed up for 3 months to 4 years.One of acute onset patients died of acute myocardial infarction and the other 5 had no relapse.The muscle strength was improved in 2 patients with chronic onset.Conclusion For the majority of SDAVF patients at the atlanto-occipital junction,the first symptom is the acute onset of subarachnoid hemorrhage and microsurgical clipping is the first choice.
