Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Hepatobiliary Surgery

Background:

  • Aberrant hepatic arteries, particularly those originating from the superior mesenteric artery (SMA), represent rare anatomical variations.
  • Aneurysms in these aberrant vessels are exceptionally uncommon, presenting unique diagnostic and therapeutic challenges.
  • The liver's sole arterial supply originating from an aberrant SMA necessitates meticulous surgical planning.

Observation:

  • Selective superior mesenteric artery angiography revealed an aneurysm.
  • The aneurysm was located in an aberrant hepatic artery.
  • This aberrant artery was the single source of arterial blood supply to the liver.

Findings:

  • The aneurysm was successfully excised.

Related Experiment Videos

  • Arterial continuity was restored using a short segment of autogenous long saphenous vein.
  • The surgical intervention preserved hepatic blood flow via the reconstructed aberrant artery.

    • Implications:

    • This case demonstrates the feasibility of surgical management for aneurysms in aberrant hepatic arteries.
    • Successful reconstruction highlights the potential for autogenous vein grafts in complex vascular repairs.
    • Highlights the importance of detailed preoperative angiography for identifying and managing rare vascular anomalies.
