耳鸣可分为搏动性耳鸣(pulsatile tinnitus,PT)和非搏动性耳鸣(non-pulsatile tinnitus,NPT),以非搏动性耳鸣为多见,搏动性耳鸣只占其中的一小部分[1]。搏动性耳鸣多由血管因素导致[2],主要是由于血管狭窄或不规则导致的血流紊乱引起,根据血管来源可分为动脉源性搏动性耳鸣和静脉源性搏动性耳鸣[3]。动脉源性致病因素包括动脉粥样硬化导致的血管狭窄和动脉瘤、颅底及颞骨血管性肿瘤、硬脑膜动静脉畸形、硬脑膜动静脉瘘、颅内及颅外动脉瘤、心输出 Tinnitus can be divided into pulsatile tinnitus (PT) and non-pulsatile tinnitus (NPT), which is more common in unstimulated tinnitus, and pulsatile tinnitus is only a small part of it [1]. Pulmonary tinnitus caused by multiple vascular factors [2], mainly due to vascular stenosis or irregular blood flow caused by disorder, according to vascular origin can be divided into arterial pulsatile tinnitus and intravenous pulsatile tinnitus [3]. Arterogenic causative agents include atherosclerosis-induced vascular stenosis and aneurysms, skull base and temporal bone vascular tumors, dural arteriovenous malformations, dural arteriovenous fistulas, intracranial and extracranial aneurysms, cardiac output
