【摘要】 对老年单纯收缩期高血压腔隙性脑梗塞发病情况进行研究，61例老年收缩期高血压（ISH组）和59例老年对照组（NT组）进行脑CT扫描。两组年龄分别为67.85±5．55和66.85±6.03岁。两组病例均无有相关临床症状和神经定位体征。结果表明腔隙性脑梗塞（LCI）者ISH组占31．11％，NT组占15．25％，两组对比有显著性差异（P＜0.05）。LCI部位两组均以基底节为多见，说明无症状LCI多见于高血压。更多还原

【Abstract】 We investignted silent lacunes in 61 elderly potientswith isolated systolic hypertension (ISH) and 59 normotensive elder-ly subjects. The mean ages of the two groupe are 67. 85±5. 55 and66. 85± 6. 03 years respetively. Although none of the ase hadany relating symptoms or sigu, silent lacunes were detected by cere-btal computerized tomography scanning in 19 petients (31.11% ) inhypettensive group and in 9 subjects (15. 25%) in normotensivegroup (P< 0. 05). The mest common site of silent lacunes was thebasal ganglia in both groupe, 78- 94% and 77. 77% respectively.These findimp indicate that silent lacunes are frequent in ISH in theelderly.更多还原
