目的观察冠状动脉(冠脉)造影时顺路行肾动脉造影的可行性,并分析肾动脉狭窄(RAS)的相关危险因素。方法选择临床明确诊断冠心病和疑诊冠心病同时合并糖尿病和(或)高血压2级以上;同时确定造影前查肾功能均正常的住院患者在冠脉造影同时行选择性肾动脉造影共72例,分析RAS的相关危险因素。结果 50例冠心病中合并RAS占14.0%,冠心病单支、双支、3支病变合并RAS的发病率分别为4.0%,13.3%,40.0%;22例非冠心病中合并RAS占9.1%;同时未有造影剂肾病(CIN)发生。结论冠脉造影顺路肾动脉造影是可行的,而年龄、高血压、高血脂、糖尿病是RAS的相关危险因素,同时植入支架是安全有效的。
Objective To observe the feasibility of bypass renal artery angiography during coronary angiography (coronary angiography) and analyze the related risk factors of renal artery stenosis (RAS). Methods The clinical diagnosis of coronary heart disease and suspected coronary heart disease were simultaneously combined with diabetes mellitus and / or hypertension more than grade 2. At the same time, the inpatients who had normal renal function before angiography were examined under coronary angiography with selective renal artery angiography Cases, analysis of RAS related risk factors. Results The incidence of RAS complicated by coronary artery disease was 4.0%, 13.3% and 40.0% respectively in 50 patients with coronary heart disease and 14.0% ; No contrast nephropathy (CIN) occurred at the same time. Conclusions Coronary artery angiography is feasible for renal artery angiography, while age, hypertension, hyperlipidemia and diabetes mellitus are risk factors of RAS. At the same time, stent implantation is safe and effective.
