例1患者男,50岁,因左侧面部阵发性放射痛5年、左听力下降3年,加重伴头晕、视物旋转、双下肢无力2天入院.既往高血压史10年.入院后颅脑CT平扫+增强:左侧延髓旁、脑桥腹侧偏右基底池内多个层面粗大的圆点或条形血管影,有轻度的占位效应,压迫脑桥,双侧额项叶白质区见对称性斑片状低密度影,边界模糊,见于多个层面.CTA显示基底动脉延长、增粗、扭曲,基底动脉上段直径为9mm,并超过床突平面12 mm.诊断为椎基底动脉扩张延长症.例2患者女性,64岁,发作性头晕、视物旋转3年,加重7天.高血压史多年.颅脑CT平扫示:延髓右前方、脑桥腹侧偏左基底池内及第三脑室后方多个层面粗大的圆点或条形血管影,有轻度的占位效应,脑干轻度受压.

目的:分析早期强化降压治疗对高血压脑出血患者血肿扩大的影响.方法:选择本院2011年6月到2012年6月急诊入院的高血压脑出血患者80例,按降压方式不同随机分为早期强化降压组(40例)和指南标准降压组(40例),分别给予强化降压和标准降压治疗.观察2组患者入院时及治疗24小时后2次头颅CT血肿体积变化情况.结果:早期强化降压组发病0～24h平均收缩压控制在145mmHg,24h内血肿体积扩大3例(
