Summary

Splenic and hepatic artery aneurysms are rare but dangerous. Prompt intervention is recommended for symptomatic cases and specific asymptomatic lesions to prevent life-threatening complications and improve outcomes.

Contemporary outcomes of open conversion after failed endovascular aortic aneurysm repair from a high-volume aortic center.

Journal of vascular surgery·2026

Area of Science:

  • Vascular Surgery
  • Interventional Radiology

Background:

  • Splenic and hepatic artery aneurysms account for 80% of visceral artery aneurysms.
  • These lesions are rare but can be life-threatening, with high mortality from emergent repair.

Purpose of the Study:

  • To define indications for intervention in splenic and hepatic artery aneurysms.
  • To compare open surgical and endovascular treatment approaches.

Main Methods:

  • Review of indications for repair of symptomatic and asymptomatic aneurysms.
  • Discussion of open surgical techniques (ligation, reconstruction) and endovascular methods (embolization, endograft placement).

Main Results:

  • Intervention is mandated for symptomatic aneurysms and specific asymptomatic lesions (e.g., >2.0 cm, in pregnant patients, or those with specific comorbidities).
  • Endovascular techniques offer alternative approaches but haven't significantly altered the risk-benefit ratio for asymptomatic lesions.
  • Both open and endovascular repairs are viable for elective treatment.

Conclusions:

  • An aggressive approach is indicated for splenic and hepatic artery aneurysms.
  • Endovascular techniques show promise for improving outcomes in symptomatic patients, though further research is needed.
