Figure 4 Therapeutic effects of balloon angioplasty and stent implantation during interventional treatment for portal vein stenosis (PVS) in pediatric liver transplantation (pLT) patients. (A, B) PVS in an 8-month-old patient after deceased donor liver transplantation for biliary atresia. (A) Stenosis of the PV is depicted (arrow). (B) Portography after balloon angioplasty shows resolution of the stenosis (arrow). (C, D) PVS in a 1-year-old patient after living donor liver transplantation for biliary atresia. (C) Initial portography shows stenosis of the PV (arrow). (D) Portography after stent placement (8 mm×4 cm), which was performed because of restenosis after balloon angioplasty, shows resolution of the stenosis (arrow).
