NEJM:一例沙门氏菌感染致假性动脉瘤案例报道

2016-05-26 MedSci MedSci原创

男性患者,66岁,既往有高血压病史,因发烧4天和声音嘶哑1天而入院就诊。据该患者称,他没有出现胸痛、咳嗽和呼吸困难等症状。

男性患者,66岁,既往有高血压病史,因发烧4天和声音嘶哑1天而入院就诊。据该患者称,他没有出现胸痛、咳嗽和呼吸困难等症状。 



常规体格检查,其体温为38.7°C,其他的检查项目未见异常。

血清学检查结果显示血白细胞计数升高。

胸片结果显示主动脉弓扩大,随着气管右侧偏移(如图A,箭头)。

胸部计算机断层扫描显示主动脉弓假性动脉瘤(如图B和C,箭头),且被广泛的气体包裹(如图B,C,D,箭头所示)。

血培养结果发现有沙门氏菌感染,最后,会诊医师根据该患者的临床症状及检查结果诊断其为沙门氏菌感染导致的主动脉弓假性动脉瘤。

随即,会诊医师对其应用哌拉西林钠/他唑巴坦钠药物进行抗感染治疗。

不久,该患者因感染形成的假性动脉瘤破裂而坍塌,接受了紧急人工血管置换手术。

术后早期患者康复良好,但在术后几个月内死亡,死因不明。

通常情况下,感染沙门氏菌导致主动脉弓假性动脉瘤的案例是非常罕见的,而一旦患者确诊,发病率和死亡率都非常高。
