Endovascular stenting of symptomatic innominate artery stenosis under distal balloon protection of the internal carotid and vertebral artery for cerebral protection: a technical case report.

The use of cerebral protection devices in endovascular treatment for innominate artery (IA) stenosis is not well established. We describe a novel technique for cerebral protection during endovascular stenting of symptomatic IA stenosis. An 82-year-old man presented with acutely scattered brain infarction by artery-to-artery embolism due to IA stenosis. Endovascular treatment for symptomatic IA stenosis was planned to prevent recurrent attacks. Endovascular stenting for IA stenosis via the right femoral artery approach was performed under simultaneous distal balloon protection of the right internal carotid artery (ICA) and vertebral artery (VA) via the right brachial artery approach. Successful treatment of symptomatic IA stenosis was achieved with no complications. The technique with simultaneous distal balloon protection of the ICA and VA provided excellent cerebral protection in stenting of IA stenosis.
