摘要

Objectives:To present a case series of modified transjugular intrahepatic portosystemic shunts(TIPS)and percutaneous transhepatic intrahepatic portosystemic shunts(PTIPS)in cirrhotic patients with variceal bleeding(VB).In addition,the scientific literature pertaining to PTIPS was reviewed.Methods:This retrospective clinical case series included six cirrhotic patients with VB who were treated with PTIPS after the failure of endoscopic band ligation or endoscopic injection sclerotherapy combined with vaso-active drugs.The treatment was conducted between January 2017 and June 2019 at a single institution.Three patients suffered from severe atrophy of the right or left lobar of the liver as well as the main right or left branch of the portal vein.The remaining three patients showed severe atrophy of the whole liver and portal vein,resulting in widening of the liver fissure.A paired t-test was used to compare the changes in portal pressure gradient between before and after the PTIPS operation.The rebleeding rate,treatment efficacy,complications,and technical success rate were all assessed during follow-up.Results:All six PTIPS procedures were performed successfully,with no severe procedural-related complications observed.None of the patients experienced VB during a mean follow-up of 22.8(range,18.0-28.0)months.The mean portosystemic pressure gradient decreased from 28.3±4.3 mmHg pre-procedure to 12.3±2.6 mmHg immediately post-procedure(P＜0.001).At follow-up,one patient was found to have developed grade 2 hepatic encephalopathy thrice during the first year,according to the West Haven criteria.However,this was resolved following medical treatment.Conclusions:When the patient's portal venous anatomy is unconducive to the performance of TIPS using the transjugular approach,PTIPS can be considered as a safe,effective complementary surgical approach for patients with VB.
