摘　　要：目的探讨F L A I R高信号血管征(F L A I R Hyperintense Vessel Sign,FHVs)在颅内静脉窦血栓形成中的诊断价值。方法回顾性选择2018年1月至2023年8月在安徽医科大学附属阜阳医院神经内科住院诊断为颅内静脉窦血栓形成的患者8例为研究组,选择同期住院的非静脉窦血栓形成的患者38例为对照组,均行头颅MRI+MRV检查。比较两组患者静脉窦FHVs的出现率。研究组静脉窦FHVs的分布范围,及其与头颅MRV的一致性。结果研究组静脉窦FHVs出现率(27.50%)明显高于对照组(4.74%,P<0.05)。静脉窦血栓患者静脉窦FHVs主要分布在横窦及乙状窦,与头颅MRV比较具有较高的一致性(Kappa=0.881,P=0.001)。FHVs的灵敏度为84.61%,特异度为100%。结论颅内静脉窦的FHVs可作为静脉窦血栓形成的影像标志物之一,对初步筛查颅内静脉窦血栓形成具有重要价值。Objective To explore the diagnostic value of FLAIR Hyperintense Vascular Signs(FHVs)in intracranial venous sinus thrombosis.Methods Retrospective collection of 8 patients diagnosed with intracranial venous sinus thrombosis in the neurology department of Fuyang Hospital of Anhui Medical University from January 2018 to August 2023 as the study group.38 headache patients hospitalized during the same period were selected as the control group.All patients underwent cranial MRI+MRV examination.Compare the incidence of venous sinus FHVs between two groups of patients.The distribution range of venous sinus FHVs in the research group and their consistency with cranial MRV.Results The incidence of venous sinus FHVs in the study group(27.50%)was significantly higher than that in the control group(4.74%,P<0.05).In patients with venous sinus thrombosis,venous sinus FHVs are mainly distributed in the transverse and sigmoid sinuses,with a higher consistency(Kappa=0.881,P=0.001)compared to cranial MRV.The sensitivity of FHVs is 84.61%,and the specificity is 100%.Conclusion The FHVs of intracranial venous sinuses can serve as imaging markers for venous sinus thrombosis and play an important role in the diagnosis of intracranial venous sinus thrombosis.
