Objective: We report a patient in whom symptomatic delayed cerebral vasospasm was suspected after mechanical thrombectomy, and medical treatment led to an improvement.
Case Presentation: A 52-year-old female. To treat embolic cerebral infarction related to occlusion of the left internal carotid artery (ICA), mechanical thrombectomy was performed, and the recanalization of the occluded blood vessel was achieved. Immediately after treatment, findings suggestive of vasospasm of the left middle cerebral artery (MCA) were noted, but subsided 2 days after admission. Transient right hemiplegia occurred 5 days after admission, and restenosis at the same site was observed. Medical treatment resulted in the disappearance of stenosis 6 days after admission.
Conclusion: Considering the risk of delayed cerebral vasospasm after mechanical thrombectomy, follow-up should be carefully conducted.
