    摘 要:目的 为评价原发性高血压和急性期深部脑梗塞的脑血流动力学状况. 方法 采用脑血流动力学分析仪(CVA)对深部脑梗塞60例(左侧n=29，右侧n=31)和CT(-)而有头晕，半身麻木，无力等症状，即时测血压增高含临界高血压的患者和血压在正常范围内的患者各30例，以及健康对照组24例进行脑血流动力学检测. 结果 脑深部梗塞组和原发性高血压组较血压正常组及健康对照组的脑血流量、流速明显降低，各组分别为:vmean (cm·s-1 )，14.0±6.0;13.7±4.5vs20.5±6.1;20.5±4.6;Q mean (mL·s-1 )8.0±2.5;8.3±2.2vs9.4±1.9;10.0±1.8(P<0.01);血管外周阻力和动态阻力明显增高，R(Pa·s·mL-1 )，2179±1192;1996±617vs1354±266;1274±197;CVR(Pa·s·cm -1 )，702±273;750±229vs503±176;481±127(P<0.01).右侧梗塞梗塞侧与对侧脑血流有显著差异(P<0.05). 结论 提示原发性高血压与深部脑梗塞对脑血流动力学有相似的不良影响.
