Remarkable recovery following prolonged out-of-hospital cardiac arrest: hypoxic-ischemic encephalopathy (HIE) versus posterior reversible encephalopathy syndrome (PRES)—a case report

Cardiac arrest is the most dramatic event that compromises the cerebral blood flow with fatal outcomes. Factors like the presence of bystander cardiopulmonary resuscitation, initial rhythm, and arrest time significantly influence outcomes. However, despite these known factors, there are still aspects of cardiac arrest-related neurological complications that remain less understood. As evidenced by limited case reports, the association between posterior reversible encephalopathy syndrome (PRES) and cardiac arrest is not widely known.
