Abstract

AbstractEndovascular management of intracranial aneurysms has become the mainstay of treatment in recent years; however, retreatment rates remain as high as 1 in 5. High‐frequency optical coherence tomography (HF‐OCT) is an emerging imaging modality for the assessment, treatment and follow‐up of cerebral aneurysms. EMBASE and SCOPUS databases were searched for studies relating to the management of intracranial aneurysm with OCT. A combination of keywords were used including ‘cerebral aneurysm’, ‘intracranial aneurysm’, ‘high‐frequency optical coherence tomography’, ‘optical coherence tomography’, and ‘optical frequency domain imaging’. There were 23 papers included in this review. For the assessment of intracranial aneurysm, OCT was able to accurately assess aneurysm morphology as well as detailed analysis of arterial wall layers. During IA treatment, OCT was used to assess and troubleshoot stent placement to optimise successful isolation from the circulation. In the follow‐up period, endothelial growth patterns were visualised by OCT imaging. OCT shows promise for the treatment of IAs at all stages of management. Due to the novel development of HF‐OCT, there is limited longitudinal data in human studies. Further research in this area is required with a focus specifically on long‐term treatment outcomes in humans.
