Abstract
Hepatic artery pseudoaneurysms (HAPs) are rare but life-threatening complications associated with hepatic artery infusion pump (HAIP) therapy for unresectable liver metastases. Traditional management options include open surgery or stent placement, but these approaches have drawbacks. We present a unique case of a dislodged stent embedded in a HAP, resulting in delayed type-I endoleak. To address this, we employed a novel technique using multiple overlapping tapered stents to reconstruct the hepatic artery. This approach successfully excluded the pseudoaneurysm without endoleak. Stent-graft placement emerges as a safer and more effective option for managing HAP, preserving hepatic arterial flow, and reducing morbidity compared to other methods. However, further research is needed to evaluate this technique's long-term outcomes and potential complications.
