【摘要】 目的 :初步了解肾动脉狭窄在高危人群中的发生率、狭窄程度、部位以及肾动脉狭窄的相关危险因素。方法 :右冠状动脉造影结束后 ,将右冠造影导管顺序置于左右肾动脉开口内 0 5cm ,边注射造影剂边撤导管。结果 :15 0例患者中 ,2 1例发现有不同程度的肾动脉狭窄 ,肾动脉狭窄的发生率为 14%。在 2 1例患者中 ,14例男性 ,7例女性 ;15例合并冠心病、高血压和吸烟 ,8例有糖尿病 ,4例曾经发生过脑血管意外。狭窄部位 :7例为开口处狭窄 ,12例为近中段狭窄 ,2例为远段狭窄 ;狭窄程度 :狭窄直径≥ 5 0 %的重度狭窄 8例 ,其中 1例近段狭窄 85 %以上 ,其余 13例肾动脉狭窄在 2 0 %～ 49%之间 ;15例为单侧肾动脉狭窄 ,6例为双侧肾动脉狭窄。结论 :肾动脉狭窄在高危人群中的发生率为 14%。更多还原

【Abstract】 Aim:To evaluate the prevalence of angiographically determined renal artery narrowing in the high risk patient population undergoing routine cardiac catheterization,and to identify the risk factors for renal artery stenosis.Methods:A total of 150 patients(106 males,44 females)were studied and the mean age was 58 years.After right coronary arteriography,renal arteriography was performed to screen for the presence of renal artery stenosis.Results:Renal artery narrowing was identified in 14% (21/150) of the patients.Significant (≥50% diameter narrowing) renal artery stenosis was found in 8 patients (5 3%) and insignificant stenosis was found in 13 patients (8.7%).The unilateral stenosis was present in 10%(15/150) of the patients and bilateral stenosis was present in 4%(6/150).The stem of the renal artery was a more common site of stenosis in 57.1% of the patients than that in the ostium (33.3%).Conclusion: The prevalence of angiographically determined renal artery narrowing in the high risk patient population undergoing cardiac catheterization is 14%.更多还原
