Özet
This study reports experience with segmental and subsegmental bile duct embolization using n-butyl cyanoacrylate (nBCA) in patients with isolated biliary obstruction after living donor liver transplantation refractory to conventional interventional treatment. Eleven liver transplant recipients with refractory biliary obstruction, despite successful external biliary drainage but failed guide wire passage across the obstructed bile duct, underwent nBCA embolization. Procedural success, adverse events, laboratory, and clinical outcomes were evaluated. Changes in embolized segment and total liver volume were assessed using paired volumetric analysis. Technical success was achieved in all patients, with 1 initial technical failure requiring repeat embolization. Major adverse events were not observed. Minor adverse events occurred in 2 patients (18.2%) and were treated with antibiotics. Volumetric analysis showed significant atrophy of embolized segments (P = .005), whereas total liver volume remained preserved (P = .206). nBCA embolization may represent a salvage option for isolated biliary obstruction after liver transplantation.
