Abstract
背景与目的急性脑梗死是Trousseau综合征(Trousseau syndrome, TS)的一种表现形式,但相对少见,往往容易被临床医师忽视。本研究探讨非小细胞肺癌(non-small cell lung cancer, NSCLC)合并TS以急性脑梗死为表现的临床、实验室检查及影像学特点。方法回顾性收集25例以急性脑梗死为表现的NSCLC合并TS患者的临床资料、实验室检查和影像学资料,进行分析总结。结果25例患者中男性18例,女性7例,年龄39岁-78岁,其中腺癌22例、鳞癌2例和大细胞癌1例;所有患者均有急性脑梗死的临床症状和体征;血浆D-二聚体明显升高,凝血酶原时间及活化部分凝血活酶时间均有不同程度的缩短;所有患者在头部磁共振成像(magnetic resonance imaging, MRI)[扩散加权成像(diffusion-weighted imaging, DWI)序列]平扫上均表现为累及多个颅内动脉供血区的急性多发性脑梗死灶,头磁共振血管成像(MR angiography, MRA)上梗死灶对应的供血血管管腔未见中重度狭窄。结论NSCLC合并急性多发性脑梗死是TS的少见表现类型,其特点是累及多个动脉供血区的急性多发性脑梗死灶伴有明显高凝状态;提高对该病的早期认识可以为临床诊疗提供一定的帮助。
