Post-traumatic hepatic artery pseudoaneurysms in children are rare but can present late after blunt or penetrating trauma. Transcatheter embolization is the preferred treatment for these hepatic artery pseudoaneurysms.

Area of Science:

  • Pediatric Surgery
  • Interventional Radiology
  • Vascular Surgery

Background:

  • Post-traumatic hepatic artery pseudoaneurysms are uncommon in pediatric patients.
  • These pseudoaneurysms can arise after both blunt and penetrating abdominal trauma.

Observation:

  • Three pediatric cases (ages 5-13) with hepatic artery pseudoaneurysms are presented.
  • Presentation varied from immediate to 2 months post-trauma.
  • Symptoms included fever, gastrointestinal bleeding, hyperbilirubinemia, and widened mediastinum.

Findings:

  • Computed tomography (CT) and angiography were used for diagnosis.
  • Transcatheter embolization was the primary treatment modality.
  • Initial technical success was achieved in all cases, with one recurrence that resolved with conservative management.

Implications:

  • Hepatic artery pseudoaneurysms in children require a high index of suspicion due to delayed and unsuspected presentations.
  • Endovascular embolotherapy is a safe and effective treatment for pediatric hepatic artery pseudoaneurysms.
  • Conservative management can lead to spontaneous resolution in select cases.
