摘要目的评价症状性颅内椎基底动脉夹层(VBD)早期的影像学表现及经保守治疗后的随访的影像学表现。材料与方法制度评审委员会允许此项回顾性分析并免除知情同意书。对210例病人的230个(48个破裂,182个未破裂)症状性VBD的影像学表现进行回顾性分析。全部病人均进行了保守治疗,也进行了MR成像及CT血管成像(CTA),因此能够对夹层的特征性表现(如壁内血肿、内膜撕裂)进行回顾性分析。
Abstract Objective To evaluate the imaging findings of early symptomatic intracranial vertebrobasilar artery dissection (VBD) and follow-up imaging after conservative treatment. The Material and Methods Review Committee allows this retrospective analysis and the waiver of informed consent. The imaging findings of 230 symptomatic VBDs in 210 patients (48 ruptured, 182 unruptured) were retrospectively analyzed. All patients underwent conservative treatment, and MR imaging and CT angiography (CTA) were performed, so that characteristic features of the dissection such as intramural hematomas and intimal tears can be analyzed retrospectively.
