Abstract Purpose To compare the clinical outcomes between patients that underwent transjugular intrahepatic portosystemic shunt (TIPS) via the left and right portal veins (PVs). Materials and methods All relevant studies in the Pubmed, Embase, and Cochrane Library databases published as of June 2020 were identified by searching, after which RevMan v5.3 was used to conduct the present meta-analysis. Relevant endpoint data were extracted from each study, related to postoperative hepatic encephalopathy (HE) rates, TIPS dysfunction, re-bleeding, and mortality. Results A total of eight studies were identified as being relevant for inclusion in this meta-analysis. These studies included 2592 total patients suffering from liver cirrhosis that underwent TIPS treatment via the left (n = 1500) or right (n = 1092) PVs.
