Visceral artery aneurysms, particularly hepatic artery aneurysms, are rare but dangerous vascular conditions. Increased diagnostic imaging and minimally invasive treatments are improving their management.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Gastroenterology

Background:

  • Visceral artery aneurysms (VAAs) are uncommon vascular diseases with a high risk of rupture and hemorrhage.
  • Hepatic artery aneurysms (HAAs) are now the most frequently reported type of VAA.
  • Increased use of percutaneous biliary procedures and CT scans for trauma contribute to the rise in HAAs.

Purpose of the Study:

  • To review the current understanding of visceral artery aneurysms.
  • To highlight the increasing incidence of hepatic artery aneurysms.
  • To discuss advancements in diagnostic and therapeutic approaches for VAAs.

Main Methods:

  • Review of recent literature on visceral artery aneurysms.
  • Analysis of trends in diagnosis and management.

Related Experiment Videos

  • Focus on the role of percutaneous catheter-based therapies.
  • Main Results:

    • Hepatic artery aneurysms represent the most common type of VAA.
    • Percutaneous diagnostic and therapeutic biliary procedures are associated with increased HAA diagnosis.
    • Computed tomography after blunt abdominal trauma also contributes to higher detection rates.

    Conclusions:

    • Visceral artery aneurysms require an aggressive diagnostic and management strategy.
    • Percutaneous catheter-based therapies are increasingly important in managing VAAs.
    • Continued vigilance and research are necessary for these rare but serious conditions.
