Percutaneous Transhepatic Stenting for Post-Transplant Hepatic Venous Obstruction Shows Durable Patency

In 27 post-living-donor liver transplant patients with hepatic venous outflow obstruction, transhepatic percutaneous stenting achieved 100% technical success, 92.6% clinical success, and 5-year primary patency of 95.2% (95% CI ~76–99%) with no major procedural complications.

• Retrospective single-center study (n=27; 21 adults, 6 pediatric) from 1,228 LDLTs over 13 years; 26/27 treated with primary stenting, 1 with angioplasty alone; mean follow-up 33.7 months.
• Kaplan-Meier overall survival was 88.9% (95% CI ~70–96%) at 1 year and 84.8% (95% CI ~65–93%) at both 3 and 5 years, supporting favorable long-term outcomes after recanalization.
• Key limitation: small retrospective single-institution cohort (n=27) limits generalizability; no comparator arm (e.g., surgical or transjugular approaches) was included.
