Endovascular Treatment of Infectious Pseudoaneurysm of Internal Carotid Artery.

Abstract

Infectious pseudoaneurysm of the intracavernous carotid artery is rare, often caused by sphenoid sinusitis or transsphenoidal surgery. Management of intracranial infectious aneurysms (IIAs) remains a controversial topic lacking randomized controlled trials to guide clinical decision making. For this case, we used an antibiotic to treat the patient in the initial stage. Because IIAs enlarge rapidly, endovascular treatment was performed in the emergency department. Unfortunately, the patient died because the IIA recurred and ruptured. Therefore we speculated that stent-assisted coil placement for the treatment of ruptured infectious pseudoaneurysms of the internal carotid artery may not be safe.
