Background Arterioportal shunts (APS) are well-known critical complications after liver transplantation (OLT). The aims of this study were to assess the frequency and causes of APS after OLT and to analyze APS patients with poor outcomes. Patients We evaluated 1415 OLT recipients retrospectively investigating APS cases. Results APS were detected in at least 9 patients (0.6%). All patients with APS had a history of posttransplant invasive procedures; percutaneous transhepatic cholangio drainage (n = 6) or needle biopsy (LNB; n = 3). Two patients with poor outcomes showed proximal APS caused by LNBs. The other 7 patients with distal APSs, showed stable conditions. Imaging findings in the 2 proximal APS patients revealed drastic changes in graft hemodynamics. Although they finally underwent re-OLT, their outcomes were poor, owing to fatal complications associated with advanced collaterals. Conclusion We concluded that even careful LNBs can cause APS at unexpected points. Earlier, more aggressive treatments are required, especially for proximal APS patients.
