Venous sinus stenting for dural venous sinus outflow obstruction due to an intrinsic filling obstruction or extrinsic stenosis is an increasingly popular treatment strategy for idiopathic intracranial hypertension (IIH) and isolated pulsatile tinnitus (PT). The most common site of stenosis is the lateral venous sinus at the transverse-sigmoid junction. Approximately 10% of the population has a persistent occipital venous sinus (OVS), a variant that may be the dominant venous drainage pathway in the setting of a hypoplastic or aplastic transverse sinus. OVS stenosis has been rarely associated with IIH and isolated PT with only a handful published cases. We herein report a retrospective series of OVS stenting in five patients, four of whom presented with non-IIH PT and one with IIH.
对于因内在充盈阻塞或外在狭窄导致的硬脑膜静脉窦流出道梗阻，静脉窦支架置入术已成为治疗特发性颅内高压（IIH）和孤立性搏动性耳鸣（PT）越来越常用的治疗策略。最常见的狭窄部位是横窦-乙状窦交界处的外侧静脉窦。约10%的人群存在持续枕静脉窦（OVS），在横窦发育不全或未发育的情况下，这一变异可能是主要的静脉引流途径。OVS狭窄很少与IIH和孤立性PT相关，仅有少数已发表的病例。我们在此报告对5例患者进行OVS支架置入术的回顾性系列研究，其中4例表现为非IIH型PT，1例表现为IIH。
