Posterior reversible encephalopathy syndrome after thoracoabdominal aortic replacement

Abstract

 Posterior reversible encephalopathy syndrome (PRES) presents with symptoms such as headache, seizure, and visual disturbances. On computed tomography or magnetic resonance imaging, PRES is characterized and diagnosed by high intensity areas in the occipital and temporal lobes. This is the first report of an adult patient with PRES due to iatrogenic hypertension because of spinal cord protection. Though the hypertension-induced PRES is treated by lowering blood pressure, in this case, maintaining cerebrospinal perfusion pressure was necessary for spinal cord protection. Earlier diagnostic imaging is important to assess the neurological symptoms after thoracoabdominal aortic replacement.
