应用支架成形治疗源于静脉窦狭窄的顽固搏动性耳鸣

Stenting treatment of venous sinus stenosis for intractable pulsatile tinnitus

目的探讨经血管内应用支架成形治疗源于静脉窦狭窄的搏动性耳鸣的有效性和安全性。方法对解放军总医院神经外科2010年1月至2011年7月收治的12例源于静脉窦狭窄的搏动性耳鸣进行支架成形治疗，全部患者经数字减影血管造影检查确诊，均表现为与耳鸣同侧的横窦、乙状窦交界处狭窄；并接受横窦、乙状窦狭窄处静脉窦支架植入术。结果术后12例患者的搏动性耳鸣症状立即消失；没有发生相关并发症。随访1-20个月，搏动性耳鸣均无复发。结论应用支架成形治疗难治性源于静脉窦狭窄的搏动性耳鸣是一种安全有效的方式。

Objective To evaluate the application, effectiveness and safety of stenting in venous sinus stenosis for intractable pulsatile tinnitus via endovaseular treatment. Methods From January 2010 to July 2011, 12 cases with intractable pulsatile tinnitus originating from cerebral venous sinus stenosis underwent stenting treatment. All of them were diagnosed by digital subtraction angiography （DSA）. There was ipsolateral stenosis in junction segment of sigmoid and transverse sinuses. The diverticulum of sigmoid sinus was found in 6 eases. Eleven patients underwent stenting placement and angioplasty for venous sinus stenosis. Results All pulsatile tinnitus symptoms disappeared immediately after stenting. No related complication was found during stenting and over a follow-up period of 3 - 22 months. There was no recurrence of pulsatile tinnitus. Conclusions Stent placement is a safe and effective procedure for pulsatile tinnitus with cerebral venous sinus stenosis.
