Remembering Dr. Jim Gillespie as a world adventurer, master surgeon, and invaluable mentor

Introduction

Polytetrafluoroethylene (PTFE)-covered transjugular intrahepatic portosystemic shunt (TIPS) stents purportedly provide superior patency. This study was undertaken to determine whether covered stents provide better long-term patency and outcomes after TIPSs.

Methods

Patients with portal hypertension undergoing TIPS at a large teaching hospital from 2001 to 2010 were studied. Median data are presented.

Results

Two hundred forty-six patients underwent TIPS; 70 received uncovered stents, and 176 received covered stents. Patients who received uncovered stents had more severely impaired liver function (41% were Child class C cirrhotics). The follow-up was longer with uncovered stents (48 vs 24 months, P < .01). Reinterventions for stenosis were undertaken in 33% with uncovered stents versus 19% with covered stents (P = .01). Shunt dysfunction occurred in 57% with uncovered stents versus 21% covered (P = .05). A deterioration of hepatic function occurred in 31% with uncovered stents versus 30% with covered (P = .32). Survival with uncovered stents was 31 months versus 33 months with covered stents (P = .55, Kaplan-Meier).

Conclusions

Covered stents may improve patency but do not mitigate postshunt hepatic dysfunction and do not improve survival.
