OVERVIEW ON POSTERIOR REVERSIBLE ENCEPHALOPATHY SYNDROME AND PREGNANCY IMPLICATIONS.

Posterior reversible encephalopathy syndrome (PRES) is a clinical radiologic syndrome characterized by visual deficits, altered consciousness, headache, confusion, seizures and focal neurological signs. Its pathophysiology is still uncertain, with vasogenic edema being the most frequent incriminated mechanism. It was described in correlation with hypertensive encephalopathy, eclampsia, use of cytotoxic and immunosuppressive drugs and renal diseases. Regarding its association with pregnancy, it is important to deliver the baby as soon as possible, to administer proper medication for hypertension, with labetalol being first choice and combat seizures or any signs of status epilepticus. A clear diagnosis can be established by combining clinical presentation with imaging techniques, especially T2 images of MRI. It has a rapid progression and good prognosis is obtained by early recognition and prompt treatment of associate condition. [ABSTRACT FROM AUTHOR]
