Liver cirrhosis is associated with higher morbidity and reduced survival with appearance of portal hypertension and resultant decompensation. Portal decompression plays a key role in improving survival in these patients. Transjugular intrahepatic portosystemic shunts are known to be efficacious in reducing portal venous pressure and control of complications such as variceal bleeding and ascites. However, they have been associated with significant problems such as poor shunt durability, increased encephalopathy, and unchanged survival when compared with conservative treatment options. The last decade has seen a significant improvement in these complications, with introduction of covered stents, better selection of patients, and clearer understanding of procedural end-points. Use of TIPS early in the period of decompensation also appears promising in further improvement of survival of cirrhotic patients.
肝硬化与较高的发病率以及门静脉高压出现后导致失代偿从而降低生存率相关。门体分流减压在改善这些患者的生存率方面起着关键作用。经颈静脉肝内门体分流术在降低门静脉压力以及控制诸如静脉曲张出血和腹水等并发症方面已知是有效的。然而,与保守治疗方案相比,它们存在诸如分流耐久性差、肝性脑病增加以及生存率未改变等重大问题。在过去十年中,随着覆膜支架的引入、更好的患者选择以及对手术终点更清晰的认识,这些并发症有了显著改善。在失代偿期早期使用经颈静脉肝内门体分流术在进一步提高肝硬化患者的生存率方面似乎也很有前景。
