  • 三例肺肿瘤血栓性微血管病的临床、影像及病理分析

    目的观察肺肿瘤血栓性微血管病(PTTM)的临床、影像学及病理特点,提高临床医生对该病的认识。方法回顾性分析南京大学医学院附属鼓楼医院 2013 年 10 月至 2016 年 8 月根据临床、影像学及病理特点确诊的 3 例 PTTM 的临床资料,总结其临床、影像学以及病理特征。结果3 例 PTTM 中男 2 例,女 1 例,年龄 29~51 岁,均为亚急性起病,主要临床表现为干咳、进行性呼吸困难。实验室检查示 D-二聚体明显增高,血气分析提示低氧血症。超声心动图肺动脉收缩压中重度增高。高分辨率 CT 均表现为双肺弥漫性小结节影、小叶间隔增厚。正电子发射计算机断层显像均证实原发肿瘤部位。3 例患者原发病均为胃癌,其中 2 例经支气管镜肺活检证实胃癌肺转移,另一例骨活检证实胃癌伴骨转移。患者入院时均未明确诊断为肿瘤,病情进展迅速,于入院后 2 周内死亡。结论PTTM 临床症状无特异性,一旦肿瘤患者出现进行性的呼吸困难及血液高凝状态,出现不明原因的肺动脉高压,而 CT 下肺动脉造影未显示肺栓塞时,应警惕 PTTM 的可能。PTTM 诊断困难,容易漏诊、误诊,缺乏有效的治疗手段,预后极差。

  • Renal toxicity of intravitreal injection of anti-vascular endothelial growth factor drugs in the treatment of retinopathy

    Anti-vascular endothelial growth factor (VEGF) drugs have been widely used in clinic by inhibiting angiogenesis to treat ocular diseases such as malignant tumors and diabetic retinopathy. However, recent studies have shown that intravitreal injection of anti-VEGF drugs may have significant systemic absorption, leading to a series of renal damages such as worsening hypertension, proteinuria, new glomerular disease, and thrombotic microangiopathy. This article reviews the renal toxicity of intravitreal injection of anti-VEGF drugs in the treatment of diabetic retinopathy and other ocular diseases, aiming to provide recommendations for clinicians.
