Transjugular intrahepatic portosystemic stent shunt (TIPS) implantation is an intervention to reduce elevated portal pressure by implantation of a stent shunt between hepatic and portal vein by transjugular approach. Elevated portal pressure is mostly caused by cirrhosis of the liver but Budd-Chiari-syndrome, venoocclusive disease, and portal vein thrombosis can also be responsible. The main indications for TIPS implantation are intractable variceal hemorrhage, prophylaxis for recurrent variceal bleeding after failure of endoscopic prophylaxis, and prophylaxis for recurrent variceal bleeding from gastric varices in the fundus. New data show that treatment of refractory ascites using TIPS implantation also leads to improved patient survival. Primary bleeding prophylaxis is not an indication for TIPS implantation. Absolute contraindications are progressive liver failure, decompensation of the right ventricle, pulmonary hypertension, and higher degree hepatic encephalopathy. The main problems after TIPS implantation are a high rate of restenosis, which frequently requires reintervention with TIPS dilatation or reimplantation, and undesirable side effects in patients after TIPS implantation for indications without proven benefit. Due to a number of prospective randomized controlled trials, the indications and contraindications for TIPS are now well defined, thus leading to a reduction of side effects and a more precise use of this important therapeutic modality for portal hypertension.
经颈静脉肝内门体分流术(TIPS)植入是一种通过经颈静脉途径在肝静脉和门静脉之间植入支架分流装置来降低门静脉压力升高的干预措施。门静脉压力升高主要由肝硬化引起,但布加综合征、肝静脉闭塞病和门静脉血栓形成也可能是其原因。TIPS植入的主要适应证为难治性静脉曲张出血、内镜预防失败后预防复发性静脉曲张出血以及预防胃底静脉曲张复发性出血。新数据表明,使用TIPS植入治疗难治性腹水也能提高患者生存率。原发性出血预防不是TIPS植入的适应证。绝对禁忌证为进行性肝功能衰竭、右心室失代偿、肺动脉高压和重度肝性脑病。TIPS植入后的主要问题是再狭窄率高,这常常需要通过TIPS扩张或再次植入进行再次干预,以及在因未证实有益的适应证而进行TIPS植入的患者中出现不良副作用。由于多项前瞻性随机对照试验,TIPS的适应证和禁忌证现已明确,从而减少了副作用,并更精确地使用这种治疗门静脉高压的重要治疗方式。
