Carotid blowout is a devastating complication in patients with head and neck malignancy. A covered stent offers an alternative to treatment of a carotid blowout patient thought to be at high risk for surgery or carotid occlusion. Stent placement in the common carotid artery or carotid bulb is a technical challenge because of large luminal diameter and luminal calibre discrepancy between internal carotid artery and common carotid artery. We present four patients with common carotid rupture and massive bleeding who were treated with self-expanding covered stents, among them, two cases were treated with newly designed self-expanding polytetrafluoroethylene (PTFE)-covered nitinol stents.
颈动脉破裂是头颈部恶性肿瘤患者的一种毁灭性并发症。对于被认为手术风险高或有颈动脉闭塞风险的颈动脉破裂患者，覆膜支架提供了一种治疗选择。由于颈总动脉管腔直径大以及颈内动脉与颈总动脉之间的管腔口径差异，在颈总动脉或颈动脉球部放置支架是一项技术挑战。我们报告了4例颈总动脉破裂并大出血的患者，他们接受了自膨式覆膜支架治疗，其中2例使用了新设计的自膨式聚四氟乙烯（PTFE）覆膜镍钛合金支架。
