Their median ages at Kasai portoenterostomy and LT were 1 and 11\u00a0months, respectively. Types of LT were living\u2010donor LT in 13, deceased\u2010donor split LT in 15, and deceased\u2010donor whole LT in three patients. PV interposition using an iliac vein homograft was performed in 28 patients receiving partial liver grafts. Side\u2010to\u2010side PV unification venoplasty was performed in three patients undergoing whole LT. All patients underwent ligation of collateral veins. IOCP was performed in 6 (19.4%) patients. Four showed no or faint residual venous collaterals. Collateral vein embolization and endovascular stenting were performed in one patient each. PV insufficiency\u2010free survival rate was 100% at 1\u00a0year and 93.8% at 3\u00a0years.
