Objective:

To compare the postoperative effectiveness of different embolization techniques for splenic artery aneurysms (SAAs), specifically the sandwich technique and mushroom technique.

Approach:

Key Findings:

• Technical success rate for both techniques was 100%.
• 30-day mortality, splenic infarction rate, and aneurysm recanalization rate were all 0.
• The number of aneurysms and the embolization method were identified as independent risk factors for PES.

Interpretation:

Limitations:

• Single-center study may limit generalizability.
• Retrospective design may introduce selection bias.

Conclusion:

The mushroom technique achieves favorable short-term outcomes comparable to the sandwich technique.
