Acute Infarction in the Artery of Percheron Territory During Cerebral Angiography: A Case Report

We present a case of a 51-year-old man with a history of hypertension and diabetes who underwent cerebral angiography for evaluation of spontaneous subarachnoid hemorrhage. The procedure was unremarkable, but the patient did not wake up and remained minimally responsive afterward. Imaging studies showed bilateral medial thalamic and midbrain infarctions consistent with an artery of Percheron infarction. The patient received antiplatelet therapy and had minimal improvement in his cognitive function. He was discharged to a rehab center after one week of hospitalization. We shortly discuss this rare complication including the risk factor, clinical presentation, and the management.
