摘要 目的:探讨以重度或恶性高血压为主要表现的并经肾活检病理证实的血栓性微血管病(TMA)患者的临床病理特点。方法:回顾性分析10例重度或恶性高血压伴肾脏损害,肾活检病理表现为血栓性微血管病的患者。结果:男8例,女2例,年龄23岁~49岁。患者均存在蛋白尿,2例为大量蛋白尿。9例患者表现为镜下血尿,1例患者为肉眼血尿。肾脏肿大、肾衰竭、贫血、乳酸脱氢酶升高、血小板减少的发生率依次为100%、100%、80%、40%和30%。肾脏病变累及小叶间动脉和入球小动脉,肾小球呈缺血性改变。2例患者行肾脏替代治疗。结论:重度或恶性高血压引起的TMA病变患者,微血管性溶血性贫血、血小板减少的发生率较低,预后较好。胃肠道及神经系统症状罕见。恶性高血压引起的TMA其发病机制可能和经典溶血尿毒综合征的发病机制不同。
