Summary
Mycotic aneurysms of the internal carotid artery are rare. This case highlights challenges in diagnosis and treatment, with endovascular balloon occlusion leading to fatal thromboembolic complications.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Neuroradiology
Background:
- Mycotic aneurysms of the intracavernous internal carotid artery are uncommon vascular pathologies.
- Management strategies are highly individualized based on patient presentation and aneurysm characteristics.
Observation:
- A patient presented with a symptomatic, expanding proximal internal carotid artery aneurysm.
- Treatment involved antibiotics and endovascular balloon occlusion.
Findings:
- The patient experienced severe thromboembolic complications post-treatment.
- This led to a fatal outcome, underscoring treatment risks.
Implications:
- Diagnosis of mycotic aneurysms can be challenging.
- Endovascular treatment, while an option, carries significant risks like thromboembolism.
- Careful patient selection, surveillance imaging, and sepsis management are crucial.
