Abstract：Objective To explore the clinical manifestations of perforator artery infarction following the treatment of intracranial dissecting aneurysm(IDA)with flow diverter(FD),and to summarize the clinical management strategies for such complications.Methods A patient with a right vertebral artery V 4 segment dissecting aneurysm was treated with flow diverter,and developed perforator artery infarction postoperatively.This study summarized the case report.Results The patient presented with clinical symptoms of numbness and weakness in the left limbs.After the right vertebral artery V 4 segment dissecting aneurysm was confirmed with cerebral angiography,an intracranial aneurysm flow diverter placement procedure was performed.Intraoperatively,the patient experienced poor local stent deployment,balloon expansion molding,and subsequent poor deployment of a balloon-expandable stent which was resolved.Postoperatively,the patient developed perforator artery infarction and was transferred to the Neurological Intensive Care Unit(NICU)for conservative treatment.Conclusion For complex aneurysms with high treatment difficulty,flow diverter treatment has good efficacy,but its complications should not be overlooked.Strict adherence to technical points during surgery and enhanced perioperative management can reduce the incidence of ischemic events and improve patient prognosis.
