A hepatic pseudoaneurysm (HPA) after blunt or penetrating liver injury is an unusual but potentially lethal complication that can develop from an injured hepatic artery branch [1–5]. Endovascular intervention with coil embolization to treat HPA is a safe and effective method and has become the standard first-line treatment, with a success rate achieving 70–100 % [13,14,15]. Infrequently the pseudoaneurysm is fed by collateral vessels and endovascular intervention may be unsuccessful. Other minimally invasive treatment options that can be considered include image guided percutaneous thrombin injection, endovascular placement of covered stents and injection of liquid agents such as fibrin glue [10,11]. We present a case of a young female who developed a post-traumatic persistent hepatic pseudoaneurysm requiring a total of nine interventions, including six endovascular interventions with angiography, three endoscopic procedures for bleeding, one percutaneous injection, and two re-admissions to the hospital. Although she avoided initial operative management, her three-month hospital course can be considered a failure of conservative management of blunt hepatic trauma due to the accrued health care costs and resources. The literature on the management of persistent pseudoaneurysm is limited. The decision to treat a persistent HPA that are found incidentally and stable in size needs further investigation.
