肾动脉粥样硬化性高血压(附13例临床分析)

Atherosclerotic Renal Hypertension(13 Cases Analyses)

目的 :总结动脉粥样硬化导致的肾血管性高血压患者的临床特点 ,为临床鉴别诊断提供参考。方法 :回顾性分析 13例动脉粥样硬化导致的肾血管性高血压患者的临床、造影及分侧肾静脉取血测定肾素比值资料。结果 :病变主要影响肾动脉近端或主动脉分叉部位 ,很少累及肾动脉分支。单侧肾动脉受累 8例 (6例左侧 ,2例右侧 ) ,双侧受累占 5例。动脉狭窄程度多重度为主。据 4例分侧肾静脉肾素比值测定 (RVRR)结果 ,病侧狭窄远端血肾素活性均比正常高 >1.5 ;健侧近端与远端肾素的比值均 <1.3。结论

Objective:To investigate the clinical characterstics of atherosclerotic renal vascular hypertension. Method:l3 cases atherosclerotics renal vascular hypertension were enrolled. renal arteries stenosis were detected by angiography. Two side renal venous blood were colected for renin activity examination.The demography of these cases were monitored Results:The origin of renal arteries is the frequent locations of atherosclerotic stenosis. Single lesion was observed in 8 cases(6 in left,2 in right). Two side involved in 5 cases. The arteries stenosis were always heavy or occlusion. Two side renal venous renin monitoring were exceeds 1.5 of RVRR in examined 4 cases, and the renin activity in health side is normal or less than 1.3. Conclusion:Atherosclerotic renal vascular hypertension is differentiated from other forms of renal vascular hypertension such as aortoarteritis or renal arteries fibromuscular dysplasia.
