凝血系统异常和血小板功能障碍常见于肾病综合征和肾小球肾炎。很多学者报告肾病综合征伴高凝状态,肾病综合征和肾小球肾炎血小板凝聚加速。增加凝血和减少纤溶在心、脑和周围血管动脉硬化中起重要作用。因凝血和纤溶障碍和肾小动脉硬化关系还未见报道,作者报告2例 IgA 肾炎伴血纤维蛋白溶酶原(plasminogen,PS)病变,并讨论其与肾血管血栓 Coagulation abnormalities and platelet dysfunction are common in nephrotic syndrome and glomerulonephritis. Many scholars report nephrotic syndrome with hypercoagulable state, nephrotic syndrome and accelerated glomerular nephritis platelet aggregation. Increases coagulation and reduces fibrinolysis in the heart, brain and peripheral vascular atherosclerosis play an important role. Because of the relationship between coagulation and fibrinolysis and renal arteriosclerosis has not been reported, the authors report two cases of IgA nephritis with plasminogen (PS) lesions, and discuss its relationship with renal vascular thrombosis
