Single-phase CT angiography predicts ASPECTS decay and may help determine when to repeat CT before thrombectomy.

Objetives: Time is relative in large-vessel occlusion acute ischemic stroke (LVO-AIS). We aimed to evaluate the rate of inter-hospital ASPECTS decay in patients transferred from a primary (PSC) to a comprehensive stroke center (CSC); and to identify patients that should repeat computed tomography (CT) before thrombectomy.

Materials And Methods: This was a retrospective cohort study of consecutive anterior circulation LVO-AIS transferred patients.

Posterior reversible encephalopathy syndrome in a patient submitted to extracorporeal membrane oxygenation for COVID-19.

A 63-year-old woman presented to the emergency department with an acute history of fever, prostration and dyspnea. She was diagnosed with severe COVID-19 acute respiratory distress syndrome and, despite optimized critical care support, met the indications for veno-venous extracorporeal membrane oxygenation. On day 34, after 7 days of wean sedation with a positive evolution of neurologic status, she presented a limited generalized tonic-clonic seizure not related to hydroelectrolytic or metabolic imbalance, which led to a diagnostic investigation; her brain imaging tests showed a posterior reversible encephalopathy syndrome.
