Endovascular Treatment of Infectious Pseudoaneurysm of Internal Carotid Artery

BACKGROUND: 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. CASE DESCRIPTION: 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. CONCLUSIONS: 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.
