Visceral artery aneurysms (VAAs) are rare but dangerous. Aggressive treatment is essential due to a high rupture risk and a 25% mortality rate in ruptured cases.

Area of Science:

  • Vascular Surgery
  • Abdominal Imaging
  • Interventional Radiology

Background:

  • Visceral artery aneurysms (VAAs) are infrequently encountered.
  • Often found incidentally, VAAs are presumed to have a benign clinical course.
  • Characterizing the clinical course of VAAs is crucial for management.

Purpose of the Study:

  • To characterize visceral artery aneurysms (VAAs).
  • To review the clinical course and outcomes of VAA management.
  • To evaluate the incidence and presentation of VAAs at a single institution.

Main Methods:

  • Retrospective analysis of all diagnosed VAAs over 10 years.
  • Examination of patient presentation, management, and therapeutic outcomes.
  • Review of associated aneurysms in patients with VAAs.

Main Results:

  • Thirty-four VAAs in 26 patients were identified.
  • Splenic artery aneurysms were most common (17 cases).
  • Rupture occurred in 42% of patients, with a 25% mortality rate for ruptured VAAs.

Conclusions:

  • Visceral artery aneurysms (VAAs) are rare but significant vascular lesions.
  • Associated aneurysms are frequently observed in patients with VAAs.
  • An aggressive treatment approach for VAAs is essential due to rupture risk and potential for fatal outcomes.
