High resolution MR imaging (HRMRI) has been used to study intracranial atherosclerotic plaques. How HRMRI guided our decision making process in endovascular intervention of basilar artery (BA) atherosclerotic disease is reported.
3 patients with symptomatic BA atherosclerotic disease underwent BA wall HRMRI under a 3 T MR scanner. Endovascular intervention was then performed utilizing HRMRI findings to guide therapy and to aid in planning the intervention.
HRMRI clearly identified the eccentric atherosclerotic plaque at the opposite side of the adjacent right anterior inferior cerebellar artery in one patient and left posterior cerebral artery in one patient, and eccentric atherosclerotic plaque protruding BA lumen at the opposite side of the adjacent right anterior inferior cerebellar artery in the remaining patient. The BA stenosis was stented without compromise of the adjacent branch arteries in the three patients.
HRMRI may be used to delineate the eccentric atherosclerotic plaque and the ostia of the major side branches of BA. The HRMRI findings seem helpful in guiding BA stenting with reduced complication risk.
高分辨率磁共振成像（HRMRI）已被用于研究颅内动脉粥样硬化斑块。本文报道了 HRMRI 如何指导我们对基底动脉（BA）粥样硬化性疾病的血管内介入治疗决策。
3 例有症状的 BA 粥样硬化性疾病患者在 3.0T 磁共振扫描仪下行 BA 管壁 HRMRI。然后根据 HRMRI 结果进行血管内介入治疗，以指导治疗并协助规划介入。
HRMRI 清楚地识别了 1 例患者对侧毗邻的右侧小脑前下动脉的偏心性粥样硬化斑块和 1 例患者对侧毗邻的左侧大脑后动脉的偏心性粥样硬化斑块，以及剩余 1 例患者对侧毗邻的右侧小脑前下动脉的偏心性粥样硬化斑块突向 BA 管腔。在 3 例患者中，BA 狭窄均采用支架置入术治疗，而不影响毗邻的分支动脉。
HRMRI 可用于描绘 BA 的偏心性粥样硬化斑块和主要侧支动脉的开口。HRMRI 结果似乎有助于指导 BA 支架置入术，降低并发症风险。
