Objectives To assess the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation using PTFE-covered stents in liver transplant (LT) recipients and to analyze the technical result of TIPS creation in split grafts (SG) compared with whole liver grafts (WG). Methods and materials Single-center, retrospective study, analyzing LT patients who underwent TIPS using PTFE-covered stents. Clinical and technical variables were analyzed. Results Between 2005 and 2021, TIPS was created using PTFE-covered stents in 48 LT patients at a median of 43 months (range, 0.5-192) after LT. TIPS indications were refractory ascites (RA) in 33 patients (69%), variceal bleeding (VB) in 9 patients (19%), others in 6 (12%). Ten patients (21%) received a SG. Technical success rate was 100% in both groups: in two WG recipients, (5%) a second attempt was required. An unconventional approach (combined transhepatic or transplenic access) was needed in 2 WG (5%) and 2 SG recipients (20%). Two procedure-related death occurred in the WG group. After a median follow-up of 22 months (range, 0,1-144), 16 patients (48%) in the RA group did not require post-TIPS paracentesis, in the VB group rebleeding occurred in 3 patients (33%). Fifteen patients (31%) underwent TIPS revision. Overt hepatic encephalopathy occurred in 14 patients (29%). Patient survival at 6 months, 1 year, and 3 years was 77%, 66%, and 43%, respectively. Conclusions The feasibility and safety of TIPS creation in SG are comparable to that of WG. TIPS creation using PTFE-covered stents represents a viable option to treat portal hypertensive complications in LT recipients.

Abstract

Objectives To assess the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation using PTFE-covered stents in liver transplant (LT) recipients and to analyze the technical result of TIPS creation in split grafts (SG) compared with whole liver grafts (WG). Methods and materials Single-center, retrospective study, analyzing LT patients who underwent TIPS using PTFE-covered stents. Clinical and technical variables were analyzed. Results Between 2005 and 2021, TIPS was created using PTFE-covered stents in 48 LT patients at a median of 43 months (range, 0.5-192) after LT. TIPS indications were refractory ascites (RA) in 33 patients (69%), variceal bleeding (VB) in 9 patients (19%), others in 6 (12%). Ten patients (21%) received a SG. Technical success rate was 100% in both groups: in two WG recipients, (5%) a second attempt was required. An unconventional approach (combined transhepatic or transplenic access) was needed in 2 WG (5%) and 2 SG recipients (20%). Two procedure-related death occurred in the WG group. After a median follow-up of 22 months (range, 0,1-144), 16 patients (48%) in the RA group did not require post-TIPS paracentesis, in the VB group rebleeding occurred in 3 patients (33%). Fifteen patients (31%) underwent TIPS revision. Overt hepatic encephalopathy occurred in 14 patients (29%). Patient survival at 6 months, 1 year, and 3 years was 77%, 66%, and 43%, respectively. Conclusions The feasibility and safety of TIPS creation in SG are comparable to that of WG. TIPS creation using PTFE-covered stents represents a viable option to treat portal hypertensive complications in LT recipients.
