Abstract:
Mycotic aneurysms of the internal carotid artery (ICA) are rare and often difficult to diagnose. They can have nonspecific signs and symptoms, an unclear etiology, and can lead to severe morbidity and mortality if left untreated. We present a case of a 47-year-old woman with an apparent mycotic aneurysm of the extracranial ICA associated with Klebsiella pneumonia. We discuss the various clinical findings and radiographic imaging that lead to this unusual diagnosis and the details of our surgical treatment, which included excision of the mycotic aneurysm and reconstruction with a greater saphenous vein interposition graft. We also review the literature on mycotic aneurysms of the ICA, including the radiologic modalities available to diagnose this condition, epidemiology, pathophysiology, and treatment options.
Insights
This case report details a rare mycotic aneurysm of the internal carotid artery (ICA) caused by Klebsiella pneumoniae. Surgical intervention with vein grafting proved successful in treating this life-threatening condition.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Radiology
Background:
- Mycotic aneurysms of the internal carotid artery (ICA) are uncommon and challenging to diagnose.
- They pose significant risks of morbidity and mortality if untreated due to nonspecific symptoms and unclear origins.
Observation:
- A 47-year-old woman presented with an extracranial ICA mycotic aneurysm.
- The condition was linked to Klebsiella pneumoniae infection.
Findings:
- Diagnosis was established through clinical evaluation and advanced radiographic imaging.
- Surgical treatment involved aneurysm excision and reconstruction using a saphenous vein interposition graft.
Implications:
- This case highlights the importance of considering infectious etiologies in arterial aneurysms.
- Effective management requires prompt diagnosis and appropriate surgical intervention, as reviewed in the literature.
