Abstract
BACKGROUND: 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. CASE DESCRIPTION: We present a case study of out-of-hospital cardiac arrest (OHCA) involving a patient with multiple comorbidities and factors that could complicate her neurological outcome. Despite experiencing a delayed recovery following the cardiac arrest event and an initial insult to the brain, the patient exhibited remarkable neurological recovery. There has been a complex individualized targeted management that contributed to the favorable outcome. CONCLUSIONS: This case study provides valuable insights into the complexities of managing OHCA patients, the factors influencing recovery, and the importance of a multidisciplinary team for early diagnosis and treatment of conditions like PRES to prevent permanent neurological damage. Further research into this area is necessary to better understand the mechanisms and implications of such associations for improving patient care and outcomes following cardiac arrest.
