Primary mycotic aneurysm of the common carotid artery: Case report

Background: Aneurysms of the common carotid artery are relatively rare. Mycotic aneurysms in such location occur even less frequently. Causative factors can be sepsis, recent surgery, or dental procedures. Immunosuppression may also be a burdening factor. Case report: The authors present the case of a 70-year-old male patient with primary mycotic carotid artery aneurysm. The patient was diagnosed with ultrasound and multidetector spiral computed tomography and treated operatively with a PTFE prosthesis. Culture-appropriate antibiotic therapy was administered during the perioperative period. Discussion: The rarity of extracranial carotid artery aneurysms might cause diagnostic and treatment difficulties. Open surgery is the recommended method, although the endovascular approach is gaining more acceptance. The choice of treatment modality might be facilitated by a detailed morpho logic description of the aneurysm and its surroundings. Available methods of imaging are described.
