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.
一名74岁男性因膀胱癌接受卡介苗治疗后发生血管迷走性晕厥。增强计算机断层扫描显示左颈内动脉、主动脉和右股总动脉有多个假性动脉瘤，考虑为感染性动脉瘤。计划对左颈内动脉进行母动脉闭塞，但由于患者躁动无法进行球囊闭塞试验；因此，患者接受了Viabahn覆膜支架治疗。大约1个月后，右颈内动脉又出现一个破裂的假性动脉瘤，同样接受了Viabahn覆膜支架治疗。患者未发生再出血或脑梗死等并发症。Viabahn可能是治疗颈动脉感染性动脉瘤的一种有效替代方法。
