Amplatzer Vascular Plug (AVP) has been utilized to occlude a congenital portosystemic venous shunt (CPSVS) that is a rare splanchnic venous anomaly. We present a case of a 12-year-old boy in whom device migration and portal vein thrombosis occurred after transcatheter closure of CPSVS using AVP type2. We reviewed the published literatures regarding with complications of CPSVS closure using AVP. Among 23 patients, we identified 5 complications including hypovolemic shock, hypoxia, liver dysfunction, device migration, and thrombosis. It is recommended to choose a device more than twice the diameter of the shunt, and to treat with an anticoagulant after closure.
