Percutaneous coil embolisation of congenital hepatic arteriovenous malformations in two patients with congenital heart disease and review of the literature

Congenital hepatic arterio-venous malformations (AVM) are rare vascular anomalies and have rarely been reported in the presence of congenital heart disease. The reported cases are mostly hemangiomas fed either by the hepatic artery itself or by one of its branches. We present two unique hepatic AVM cases in the presence of congenital heart defects in which the AVM was not fed by the hepatic arterial system. Transcatheter coil embolisation was successfully carried out in both of them by using non-detachable Gianturco coils. Complete occlusion was achieved without any sequel.
