颅内硬脑膜动静脉瘘的病变部位与MRI的诊断价值分析

摘要

Objective To analyze relationship between MRI features and the clinical symptoms of dural arteriovenous fistula among different lesions.Methods A total of 89 patients with DAVF diagnosed by DSA were retrospectively analyzed.Clinical materials were collected and divided into invasive and benign,MRI features,as well as the lesion location and clinical classifications according to the whole cerebral angiography.Results The clinical manifestations of DAVF in different parts are different,and MRI manifestation was correlated with the severity of symptoms.The positive rates of MRI in different parts of DAVF were different.Conclusion As a non traumatic examination method,MRI can provide a high diagnostic sensitivity,but this sensitivity is correlated with DAVF of the lesion site.%目的 分析不同病变部位的硬脑膜动静脉瘘的MRI表现与临床症状的关系.方法 回顾分析89例经DSA确诊的DAVF患者的MRI表现.收集病例资料,分为侵袭性和良性、MRI特征以及根据全脑血管造影检查后的病变位置及临床分型.结果 不同部位的DAVF临床表现不同,MRI的表现与症状的严重程度相关.不同部位的DAVF的MRI检查阳性率不同.结论 MRI作为一种非创伤的检查手段,虽然能够提供较高的诊断敏感性,但是这种敏感性与DAVF的病变部位相关.
