摘要(Abstract)：
目的观察冠状动脉造影及介入治疗术后胆固醇结晶栓塞的发生情况、临床特点及治疗情况。方法6例动脉粥样硬化患者因急性肾衰竭、外周皮肤缺血性损害,诊断为胆固醇结晶栓塞,收集其临床资料,并随访预后情况。结果6例患者中5例为男性,平均年龄72岁,多数伴有高血压、糖尿病、吸烟等动脉粥样硬化的危险因素。6例患者均在冠状动脉造影后出现血肌酐水平进行性升高,皮肤损害表现为肢端蓝紫色淤斑。1例患者的足趾皮肤活检见到胆固醇结晶栓子。所有患者应用他汀类药物治疗,2例患者给予肾替代治疗。随访有3例患者死亡,3例患者仍为慢性肾衰竭。结论医源性胆固醇结晶栓塞的发病率逐渐增高,临床医生对此病应有足够的认识。
