A retrospective study of magnitude of cases of posterior reversible encephalopathy syndrome and its correlation with preeclampsia

Introduction: PRES is a clinico-radiological entity also known as a posterior leucoencephalopathy syndrome. PRES has been associated with many condition including eclampsia, severe hypertension and auntoimmune disorders. Global incidence of PRES is unknown. Incidence of PRES amongst eclampsia patient is 17.4% and common in primigravida. Purpose of this study is to know the magnitude of PRES cases and its correlation in pre eclampsia. Aims and Objectives: To find out the magnitude of PRES cases in KIMS hospital Bangalore and its correlation with pre eclampsia. Materials and Methods: This retrospective study was performed in the department of obstetrics and gynaecology in KIMSH and data was collected from medical record section over a period of 18 months from June 2017 to October 2019. Detailed history and appropriate data was collected from the records and case file after selecting the cases based on inclusion and exclusion criteria. Each patients case record was analyzed with regard to age, parity, antenatal history, intrapartum and postpartum period, complications if any and further investigations. Results: In our study 360 patients were pre eclamptic out of which 21 of them had eclampsia and 8 of them were diagnosed as PRES on neuro imaging (2.2%). Conclusion: Hence we find that there is association between PRES and pre eclampsia and timely intervention is required to prevent further permanent complications and neurological deficits.
