Teaching NeuroImages: Visual loss as a rare complication of mechanical thrombectomy.

A 46-year-old womanwas admitted to the emergency department with a severe left hemispheric syndrome (NIH Stroke Scale [NIHSS] 11). CT showed an occlusion of the left middle cerebral artery, reaching from the distal main trunk (M1) to the inferior division (M2) (figure 1). IV thrombolysis was started and mechanical thrombectomy performed successfully. Postinterventional clinical examination showed mild aphasia (NIHSS 1). However, the patient also complained about impaired (“foggy”) vision of the left eye.
