Objective:

To report a rare case of mycotic pseudoaneurysm in the common femoral artery resulting from septic ankle arthritis and discuss management strategies, emphasizing its significance in the context of existing literature.

Key Findings:

• Mycotic aneurysms are rare and can arise from remote infections like septic ankle arthritis, highlighting the need for awareness among clinicians.
• Surgical management with autologous vein grafts shows favorable outcomes in infected cases, suggesting a shift in management strategies.
• Endovascular techniques can be safely utilized post-surgery with careful planning, emphasizing the importance of multidisciplinary approaches.

Interpretation:

This case highlights the complexity of managing mycotic pseudoaneurysms and the importance of a multidisciplinary approach in surgical and endovascular treatment, reinforcing the need for clinician awareness.

Limitations:

• The rarity of the condition limits generalizability of findings, and potential biases or confounding factors should be acknowledged.
• Long-term outcomes of the combined surgical and endovascular approach require further study.

Conclusion:

The successful management of this mycotic pseudoaneurysm illustrates the potential for effective surgical and endovascular strategies in complex vascular infections, underscoring the importance of clinician awareness.
