A spinal CSF-venous fistula is an increasingly recognized type of CSF leak that causes spontaneous intracranial hypotension. The detection these fistulas requires specialized imaging such as digital subtraction myelography or dynamic CT myelography, and several treatment options are available. novel for consisting transvenous embolization with the liquid embolic agent Onyx has been described recently, but some patients require further if fails. purpose this study was to evaluate safety effectiveness surgery following embolization. In a series 6 consecutive who underwent surgical ligation after endovascular embolization, there were no complications. Postoperatively, complete resolution symptoms reported by 5 patients, brain MR findings hypotension resolved in all patients. This suggests effective safe.
