乙状窦憩室致搏动性耳鸣的介入治疗成功案例报道

Interventional therapy for pulsatile tinnitus caused by sigmoid sinus diverticulum: a case report

乙状窦憩室是引起静脉性搏动性耳鸣的重要原因之一。该病虽然发病率不高,但可能导致严重的症状,需及时诊断和治疗。该例患者无明显诱因下出现左侧持续性、搏动性耳鸣,呈吹风样,与心搏频率一致,按压左颈部静脉时耳鸣消失,是静脉搏动性耳鸣的典型症状,全脑血管造影术提示左侧乙状窦憩室大而复杂。采用经血管介入弹簧圈填塞术治疗,术后患者耳鸣症状明显改善。介入治疗为静脉窦源性搏动性耳鸣的治疗提供了新的选择途径。

Sigmoid sinus diverticulum is one of important reasons for causing pulsatile tinnitus. Although the incidence of pulsatile tinnitus caused bysigmoid sinus diverticulum is low, it can lead to serious symptoms requiring diagnosis and treatment in time. This reported patient developed continuousand pulsatile tinnitus at left side without any precipitating factors. The tinnitus was blowy-like with the same rate as heartbeat and disappeared whenpressing the left jugular vein, which were typical symptoms of venous pulsatile tinnitus. The cerebral angiography suggested that there was a big andcomplex sigmoid sinus diverticulum at left side. The patient’s tinnitus symptom was improved remarkably after undergoing the endovascular interventionaltreatment with coil embolization. It indicated that interventional therapy can provide a new option for the treatment of venous sinus origin pulsatiletinnitus.
