A patient with hypopharyngeal cancer developed carotid blowout syndrome (CBS) treated by self-expandable stent-graft in the left carotid artery. CT scan for progressive right hemiparesis 4 months later showed multiple left cerebral abscesses and left carotid thrombosis. Although deployment of stent-grafts for CBS can achieve initial hemostasis in patients with head-and-neck cancer, the placement of a stent-graft in a field of necrosis and infection is associated with poor long-term outcome. We recommend the use of prophylactic antibiotics if endovascular foreign materials are placed in a contaminated field.
一名下咽癌患者发生了颈动脉破裂综合征（CBS），通过在左颈动脉置入自膨式覆膜支架进行治疗。4个月后，因进行性右侧偏瘫行CT扫描显示左侧多个脑脓肿及左颈动脉血栓形成。尽管为CBS置入覆膜支架可使头颈癌患者实现初始止血，但在坏死和感染区域置入覆膜支架与远期预后不良相关。如果在污染区域放置血管内异物，我们建议使用预防性抗生素。
