    • 三例肺腫瘤血栓性微血管病的臨床、影像及病理分析

      目的觀察肺腫瘤血栓性微血管病(PTTM)的臨床、影像學及病理特點,提高臨床醫生對該病的認識。方法回顧性分析南京大學醫學院附屬鼓樓醫院 2013 年 10 月至 2016 年 8 月根據臨床、影像學及病理特點確診的 3 例 PTTM 的臨床資料,總結其臨床、影像學以及病理特征。結果3 例 PTTM 中男 2 例,女 1 例,年齡 29~51 歲,均為亞急性起病,主要臨床表現為干咳、進行性呼吸困難。實驗室檢查示 D-二聚體明顯增高,血氣分析提示低氧血癥。超聲心動圖肺動脈收縮壓中重度增高。高分辨率 CT 均表現為雙肺彌漫性小結節影、小葉間隔增厚。正電子發射計算機斷層顯像均證實原發腫瘤部位。3 例患者原發病均為胃癌,其中 2 例經支氣管鏡肺活檢證實胃癌肺轉移,另一例骨活檢證實胃癌伴骨轉移。患者入院時均未明確診斷為腫瘤,病情進展迅速,于入院后 2 周內死亡。結論PTTM 臨床癥狀無特異性,一旦腫瘤患者出現進行性的呼吸困難及血液高凝狀態,出現不明原因的肺動脈高壓,而 CT 下肺動脈造影未顯示肺栓塞時,應警惕 PTTM 的可能。PTTM 診斷困難,容易漏診、誤診,缺乏有效的治療手段,預后極差。

    • 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.
