Summary
This case study highlights bacterial endocarditis complicated by fungal aneurysms in the superior mesenteric and popliteal arteries. Prompt diagnosis and a combined medical-surgical approach, prioritizing autologous vein grafts, are crucial for managing these rare vascular complications.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Cardiology
Background:
- Bacterial endocarditis can lead to rare but severe complications, including mycotic aneurysms.
- Fungal aneurysms are uncommon sequelae of infective endocarditis, posing diagnostic and therapeutic challenges.
Observation:
- A single case presented with bacterial endocarditis complicated by fungal aneurysms in both the superior mesenteric and popliteal arteries.
- Diagnosis of the popliteal aneurysm was straightforward, whereas the superior mesenteric aneurysm presented diagnostic difficulties.
Findings:
- Arteriography is essential for diagnosing such aneurysms and should be employed liberally.
- Optimal management involves a combination of medical therapy and carefully considered surgical intervention.
- Surgical strategy should favor restoring vascular continuity using autologous venous material via an extra-anatomic bypass.
Implications:
- This case underscores the importance of high clinical suspicion for mycotic aneurysms in endocarditis patients, particularly with atypical presentations.
- It emphasizes the critical role of advanced imaging and a multidisciplinary approach in managing complex vascular infections.
- The preferred surgical technique offers a potentially safer and more durable solution for these challenging aneurysms.
