通过X线摄影对与静脉搏动性耳鸣（PT）相关的各种血管异常和变异进行全面评估对于制定治疗计划和改善临床结果至关重要。本研究评价了PT侧各种血管异常和变异的发生率，并确定这些病变是作为多个实体还是单个实体发生。回顾性分析了242例单侧静脉性PT患者的双期增强CT图像。分析有症状和无症状侧的血管异常和变异，并比较每侧血管异常或变异的发生率。计算每例患者症状侧的异常和变异数量。(1)共有170例患者（170/242）在症状侧有一个以上的异常或变异，58例患者（58/242）在断层扫描上有一个病灶。(2)乙状结肠板裂开的发生率有统计学显著差异（P = 0.000），侧窦狭窄（P = 0.014），颈静脉球高位（P = 0.000），乙状窦憩室（P = 0.000）、颈静脉球憩室（P = 0.000）、颈静脉球裂开（P = 0.000）和症状侧与无症状侧之间的大导静脉（P = 0.006）。(3)乙状结肠板裂开（86.4%）是症状侧最常见的病变，其次是侧窦狭窄（55.8%），颈静脉球高位乙状窦憩室占47.1%（34.3%），颈静脉球憩室其中颈静脉球破裂13.6%，大导静脉4.1%，静脉窦血栓1.2%，岩鳞窦0.8%。各种血管异常和变异更常发生在静脉PT侧。初步研究结果表明，静脉PT患者可能有多个血管异常或变异的症状。
A comprehensive assessment of various vascular anomalies and variants associated with venous pulsatile tinnitus (PT) by radiography is essential for therapeutic planning and improving the clinical outcome. This study evaluated the incidence of various vascular anomalies and variants on the PT side and determined whether these lesions occurred as multiple or single entities. The dual-phase contrast-enhanced computed tomography images of 242 patients with unilateral venous PT were retrospectively reviewed. The vascular anomalies and variants on the symptomatic and asymptomatic sides were analyzed, and the incidences of anomalies or variants on each side were compared. The number of anomalies and variants on the symptomatic side in each patient was calculated. (1) A total 170 patients (170/242) had more than one anomaly or variant on the symptomatic side, and 58 patients (58/242) had a single lesion on tomography. (2) There was a statistically significant difference in the incidence of dehiscent sigmoid plate (P = 0.000), lateral sinus stenosis (P = 0.014), high jugular bulb (P = 0.000), sigmoid sinus diverticulum (P = 0.000), jugular bulb diverticulum (P = 0.000), dehiscent jugular bulb (P = 0.000), and a large emissary vein (P = 0.006) between the symptomatic and asymptomatic sides. (3) Dehiscent sigmoid plate (86.4%) was the most frequent lesion on the symptomatic side, followed by lateral sinus stenosis (55.8%), high jugular bulb (47.1%), sigmoid sinus diverticulum (34.3%), jugular bulb diverticulum (13.6%), dehiscent jugular bulb (13.6%), large emissary vein (4.1%), sinus thrombosis (1.2%), and petrosquamosal sinus (0.8%). Various vascular anomalies and variants occur more frequently on the venous PT side. Preliminary findings suggest that venous PT patients may have multiple vascular anomalies or variants on the symptomatic side.
