Teaching NeuroImage: Etiologic Investigation Using Optical Coherence Tomography During Thrombectomy

Year: 2023

Type: article

Abstract: A 24-year-old man with an acute left middle cerebral artery occlusion underwent a thrombectomy.A filling defect was observed in the culprit lesion after the first clot retrieval (Figure , A). Intraoperative optical coherence tomography (OCT) was then performed to investigate the etiology, Figure Intraoperative Findings (A) A filling defect after the first clot retrieval.(B and C) OCT revealed a fibrous plaque with intact fibrous cap (lowattenuating, signal-rich lesion, star) and white thrombi (intralumenal low-attenuating, signal-rich masses, arrowhead).(D) A successful second clot retrieval.(E and F) Repeated OCT confirmed the unruptured plaque and residual white thrombi.OCT = optical coherence tomography.
