Liver transplantation as a rescue surgery after failure of embolization of a giant hepatic artery pseudoaneurysm.

We present the case of a male diagnosed with a giant hepatic artery aneurysm, which first presented with pain and hemorrhage due to a partial rupture of the aneurysm. After discarding treatment with a stent or surgery due to the wide extension, we chose to embolize the hepatic artery with coils. However, the progress was unfavorable after the procedure, with the appearance of liver failure that was resolved by an urgent liver transplantation. Giant hepatic artery pseudoaneurysms are an infrequent entity and their management is a great challenge. The diagnosis is usually delayed due to non-specific clinical signs and the life of the patient may be threatened in the case of rupture. Thus, endovascular or surgical treatment is recommended. Aneurysm embolization or ligation has been described in the literature as a valid treatment option in cases where revascularization by stent or bypass is not possible, as it preserves the viability of the liver due to the portal flow and collateral arteries. However, in the case of the failure of these treatments, liver transplantation is a rescue option.
