Management of Delayed Hepatic Artery Pseudoaneurysm with Arterioportal Fistula

Background

Hepatic artery pseudoaneurysm (HAP) is a rare but serious complication of liver trauma, often leading to severe outcomes if not identified and managed promptly. This case highlights the need for vigilance in monitoring patients after liver injuries, especially those with penetrating mechanisms.

Data Highlights

No numerical data available.

Key Findings

• A 25-year-old male developed a hepatic artery pseudoaneurysm after a stab wound.
• Initial Gelfoam embolization was unsuccessful in managing the pseudoaneurysm.
• Definitive coil embolization via the femoral artery successfully excluded the lesion.
• The patient experienced symptomatic improvement and was discharged in stable condition.
• Delayed vascular complications following penetrating liver trauma require careful monitoring.

Clinical Implications

Healthcare professionals should maintain a high index of suspicion for vascular complications in patients with liver trauma.

Conclusion

This case highlights the importance of recognizing delayed vascular complications in liver trauma.
