Stent retriever angioplasty for acute atherosclerotic occlusion of internal carotid artery: A case report

Surg Neurol Int. 2022 Oct 21;13:482. doi: 10.25259/SNI_729_2022. eCollection 2022.

ABSTRACT

BACKGROUND: Despite the proven benefit of stent retriever thrombectomy for acute ischemic stroke caused by large-vessel embolic occlusion, acute revascularization in the setting of underlying intracranial, atherosclerosis-related, and emergent large-vessel occlusion remains to be a challenge. In this case report, we present a novel revascularization technique that can be used to treat acute ischemic stroke caused by suspected intracranial, atherosclerosis-related, and emergent large-vessel occlusion of the internal carotid artery (ICA).

CASE DESCRIPTION: This case report presents two patients with intracranial, atherosclerosis-related, and emergent large-vessel occlusion of the ICA: a 73-year-old man with a right-sided hemiparesis and aphasia and a 60-year-old man with altered level of consciousness. These patients were treated using the prolonged deployment and partial resheath method with a stent retriever, using the following devices: Solitaire Platinum, Trevo Trak 21, and AXS catalyst 6 for suction. On prolonged deployment of the Solitaire Platinum device, underlying focal atherosclerotic disease was noted. The device remained in place for more than 10 min, until the blood vessel was occluded. Next, the device was partially resheathed into the Trevo Trak 21 to reduce the radial force and minimize vessel injury during the pull. The partially constrained device was then retrieved under continuous aspiration at the lesion site and blood flow was successfully restored. Both patients recovered without any new deficits.

CONCLUSION: The prolonged deployment and partial resheath method using a stent retriever may be safe and effective in the treatment of intracranial, atherosclerosis-related, and emergent large-vessel occlusion of the ICA.
