Between 6th and 14th weeks afteconstricted bilateral renal arteries, the blood pressure in the majority of RHRSP with cerebral infarction was obviously higher than in RHRSP without cerebral infarction (28. 8±2. 24kPa～32. 3 ±2. 88kPa, 26. 2±2. 01～28. 3±2. 33kPa respectively). Severe hyalinosis, fibrosis, wall hypertrophy, lumen stenosis, and even microaneurysm formation in cerebral small arteries in RHRSP with cerebral infarction were found, while slight to mild arteriolosclerosis in RHRSP was found without cerebral infarction.

本实验发现，RHRSP在经受不同水平的低血压后，产生脑梗塞的大多数（32/38只）在肾动脉狭窄术后第六周至第十四周，血压为28.8±2.24 kPa～32.3±2.88 kPa（216±17mmHg～242±22mmHg），显著高于无脑梗塞的RHRSP，并且发现这些RHRSP的脑内小血管呈严重的透明样变、纤维素样变性，管壁增厚，管腔狭窄，部分有微动脉瘤形成；而无脑梗塞的RHRSP的血压为26.2±2.01kPa～28.3±2.33 kPa（200±15mmHg～212±17.5mmHg），其脑内小血管呈轻至中度的动脉硬化改变。
