Use of a dedicated open transcarotid access system for neurovascular disease.

BACKGROUND: Transcarotid artery revascularization (TCAR) is an increasingly popular technique for the management of extracranial carotid stenosis. Its off-label use in the treatment of intracranial neurovascular disease is poorly described. Our objective is to describe the use of a dedicated open transcarotid access system for the treatment of neurovascular pathologies other than extracranial carotid stenosis.

METHODS: We conducted a retrospective review of a prospectively maintained database of consecutive patients who underwent treatment of neurovascular disease at a single academic center using the ENROUTE Transcarotid Arterial Sheath. Demographics, procedural characteristics, and patient outcomes were reported.

RESULTS: Twenty patients were included in the study between September 2017 and March 2023. The following pathologies were treated: intracranial atherosclerotic disease (ICAD, nine patients), complex cervico-petrous carotid disease (five patients), intracranial aneurysms (three patients), and large vessel occlusion-acute ischemic stroke (three patients). Eighteen of the 20 cases were performed with active carotid flow reversal. All cases were successfully completed. There were no access-related complications. One periprocedural complication was incurred: a microguidewire perforation during an exchange maneuver for the treatment of ICAD.

CONCLUSION: An open transcarotid approach using a dedicated transcarotid system may offer a safe alternative access strategy for the endovascular treatment of complex neurovascular pathologies when a traditional transfemoral or transradial approach is contraindicated or failed.
