Ruptured Infected Pseudoaneurysms of Bilateral Carotid Artery Treated with Viabahn Stent Graft: A Case Report

A 74-year-old man who had received Bacillus Calmette-Guérin therapy for bladder cancer developed vasovagal syncope. Contrast-enhanced computed tomography showed multiple pseudoaneurysms in the left internal carotid artery, aorta, and right common femoral artery, which were considered to be infected aneurysms. Parent artery occlusion was planned for the left internal carotid artery, but the balloon occlusion test was not possible because of the patient's restlessness; therefore, the patient was treated with a Viabahn stent graft. Approximately 1 month later, another ruptured pseudoaneurysm occurred in the right internal carotid artery, which was also treated with a Viabahn stent graft. The patient did not experience rebleeding or complications such as cerebral infarction. Viabahn may be an effective alternative for the management of carotid artery-infected aneurysms.
