可逆性后部脑病综合征患者血压与临床表现、脑水肿程度的关系

目的探讨可逆性后部脑病综合征患者血压与脑水肿程度及临床表现之间的关系。方法收集15例存在典型可逆性后部脑病综合征临床表现和MRI改变患者15例,分析血压高低与脑水肿的程度、临床症状之间的关系。结果应用SPSS16．0软件进行统计学分析,平均动脉血压的高低和脑水肿的分布呈中度相关性（Spearman’SPtest,r=0．409,P=0．004,P〈0．05）,但与临床症状的表现无明显相关性。结论通过血压的高低可以预测病灶的大小及弥漫程度,这对早期治疗,提示预后有明显帮助。

The relationship between blood pressure and cilinical manifestations,degree of encephaledema in posterior re-versible encephalopathy syndrome

Objective To investigate the associations between blood pressure and clinical manifestations, degree of enceph- aledema in patients with posterior reversible encephalopathy syndrome （PRES）. Methods Fifteen patents with typical clinical symptoms and characteristic MR imaging findings of PRES were included in this study. Correlation analysis between blood pressure and the scores of encephaledema .clinical manifestations was performed. Results Mean arterial pressures were moder- ately correlated with the scores of encephaledema distribution （Spearman＇s p test, r--0. 409, P~0. 004, P~0. （/5）, but not correlated with clinical manifestations. Conclusion The size and extent of diffusion of lesions may be predicted by ＊he level of blood pressure in patients with PRES, which has great benefit for early treatment and judging prognosis.
