Percutaneous transluminal angioplasty vs. stenting for hepatic artery stenosis after liver transplantation in adults: a systematic review and meta-analysis

However, stenting offers lower reintervention rates and longer recurrence-free intervals, suggesting better long-term outcomes. Treatment selection should be individualized, considering anatomical factors, stenosis morphology, and operator expertise.
