BACKGROUND Arteriovenous fistula of the sigmoid sinus is an abnormal connection of arteries with the sigmoid sinus.Endovascular treatments of such lesions are considered safe and with low rates of complications.CASE SUMMARY A 62-year-old female patient underwent endovascular treatment of an arteriovenous fistula of the right sigmoid sinus on February 7,2017,but her tinnitus was not cured.She was admitted to the Beijing Tiantan Hospital,Capital Medical University,on March 20,2017,and her pre-operative diagnosis,by digital subtraction cerebral angiography,was arteriovenous fistula of the sigmoid sinus.She underwent endovascular embolization of the distal occipital artery and posterior auricular artery using Onyx-18.The arteriovenous fistula of the sigmoid sinus was cured,and her tinnitus disappeared,but ischemia of the upper 2/3 of the right auricle occurred without hearing loss.The patient received treatment to improve microcirculation,in addition to fluid supplementation,analgesia,and hyperbaric oxygen,and the swelling due to ischemia in the right auricle did not progress further.The patient reported no tinnitus,and the right auricle had returned to normal 3 years later.CONCLUSION Ischemic complications of vital organs should be considered when performing embolization procedures for arteriovenous fistulas of cerebral sinuses.Compensation of the organs should be evaluated before the operation,and the related treatment regimens should be planned. 展开更多
