Visceral artery aneurysms (VAA) require prompt treatment. Aggressive surgical intervention for VAA offers low morbidity and mortality, making it preferable over endovascular methods for most cases.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Abdominal Imaging

Background:

  • Visceral artery aneurysms (VAA) are rare but can lead to severe complications.
  • Prompt diagnosis and treatment are crucial for managing VAA effectively.

Purpose of the Study:

  • To review the institution's experience with the treatment of visceral artery aneurysms.
  • To compare the outcomes of surgical versus endovascular VAA treatment.

Main Methods:

  • Retrospective review of 31 VAA cases treated between 1988 and April 2002.
  • Analysis of patient demographics, aneurysm location, treatment modalities (open surgery, endovascular), and outcomes.
  • Comparison of perioperative morbidity and mortality rates between treatment groups.

Main Results:

  • The most common VAA locations were the splenic (16) and hepatic (7) arteries.
  • Open surgery was performed in 25 patients (22 elective, 3 emergency) with a 3.6% mortality and 7.1% morbidity.
  • Endovascular treatment was used in 7 patients, with 0% mortality but 14.3% morbidity and 42.9% procedure failure rate.

Conclusions:

  • An aggressive surgical approach for VAA is recommended due to low morbidity and mortality.
  • Endovascular treatment for VAA should be reserved for highly selected cases.
  • Even asymptomatic VAA may warrant surgical consideration given the risks of rupture.
