Correlation Between Vasogenic Edema And Blood Pressure In Posterior Reversible Encephalopathy Syndrome

Objective:To investigate the correlation between vasogenic edema and blood pressure in posterior reversible encephalopathy syndrome(PRES).Methods:The clinical and radiologic data were retrospectively analyzed in forty-five patients.Bartynski vasogenic edema score standard was used to score vasogenic edema, mean arterial blood pressure that patients with blood pressure levels. The correlation between vasogenic edema and mean arterial pressure in PRES was analysed.Results:Forty-five patients with hypertension was 88.9%, over the upper limit of cerebrovascular autoregulation was 20.0%.No correlation existed between vasogenic edema and mean arterial pressure in PRES (r= 0.158, p=0.3, N=45).No correlation existed between vasogenic edema and mean arterial pressure in PRES with hypertension (r=0.517, p=0.19, n=9), No correlation existed between vasogenic edema and mean arterial pressure in PRES with pre-eclampsia/eclampsia (r=0.161, p=0.462, n= 23).Conclusion:Vasogenic edema resolves spontaneously without blood pressure management, systemic toxicity and endothelial cell injury might confer the susceptibility to vasogenic edema.
