title: The difference of each angiographic finding after multiple stent according to stent type in bilateral vertebral artery dissection.
abstract: We report a case of spontaneous bilateral intracranial vertebral artery dissecting aneurysms with subarachnoid hemorrhage. One dissecting lesion was treated with a coronary balloon-mounted stent (BMS) technique; however, due to differences in access route tortuosity, the other lesion was treated with a self-expandable stent (SES) technique. After 2 months, the angiographic outcome showed complete healing of the dissected segment on the side that was treated with BMS; in contrast, the dissection lesion appeared to be re-growing on the side that was treated with SES. Complete treatment of the aggravated lesion was achieved by additional deployment of BMSs. Therefore, we have provided a discussion of the possible reasons for this difference in outcome according to the stent type.
