Hepatology:肝内门静脉系统分流术后肝硬度增加与炎症相关,并可预测死亡率

2018-04-24 MedSci MedSci原创

研究表明,系统炎症出现后,TIPS术后,患者肝脏硬度增加的风险增高;是器官衰竭和死亡的预测因素。

研究背景:经颈静脉内门静脉分流术(TIPS)可以有效治疗门静脉高压症并发症。肝脾僵硬可能能够预测门静脉高压症的出现与否。这项前瞻性研究调查了接受TIPS的患者的肝脏僵硬程度,无论患者是否存在门静脉高压的指征。

研究方法:在83例患者中,16例患者(急性组)在TIPS术前和TIPS后30分钟内进行了瞬时弹性成像检测;67例患者(慢性组)在TIPS术前1天和TIPS术后7天进行了肝、脾横波弹性成像检测。在TIPS术前,从门静脉、肘静脉、肝静脉获得样品,检测这些样品中的IL1b, IL6, IL8, IL10, IL18和γ-干扰素等水平。

研究方法:27例患者(5例急性组的患者,22例慢性组的患者)肝脏硬度增加大于10%。56例患者,肝脏硬度下降或保持不变。重要地是,全部慢性组患者,脾脏硬度降低。肝脏硬度增加的患者与肝脏硬度未增加的患者,两组患者在临床和实验室参数上没有差异。肝脏硬度增加的患者,TIPS术时,促炎细胞因子水平增高;在TIPS术后,发生器官衰竭的风险增高,生存率降低。C反应蛋白和肝硬度增加超过10%是患者发生死亡的独立预测因素。

研究结论:研究表明,系统炎症出现后,TIPS术后,患者肝脏硬度增加的风险增高;是器官衰竭和死亡的预测因素。

内镜技术来了,TIPS该走向何处?

  经颈静脉途径肝内门体静脉支架分流术(TIPS)是治疗门静脉高压症食管胃静脉曲张出血的介入治疗技术之一。经过20余年的基础和临床研究,人们对TIPS的临床应用价值已经有了比较一致的认识。   与外科治疗(分流和断流术)相比,TIPS具有创伤性小、技术成功率高、可控制分流道直径、能同时栓塞静脉曲张以及并发症发生率低等优点。   但关于TIPS的应用也存在一些争议。尤其是随着内镜技术应用的日益广

  概述   肝硬化门静脉高压是形成门静脉血栓的主要原因之一,约24%~32%的门静脉血栓患者存在肝硬化血栓形成。血栓形成可减少流向肝脏的血液量,加重肝损害。门静脉压升高可引起出血、腹水、淤血性肠坏死,甚至可导致门静脉高压性胆管病和儿童发育迟缓。   目前研究表明,门静脉血栓形成可能与门静脉阻力增加,血流状态改变有关。最新研究证实,血栓形成与患者的肝功能密切
