Abstract

PurposeThis case report aims to describe the rare and severe complication of carotid artery stent expulsion via an oropharyngeal fistula (OCF) in a 59-year-old male with head and neck cancer. The study emphasizes the unique interplay between oropharyngeal cancer and carotid artery blowout and highlights a novel presentation of OCF in a patient with advanced comorbidities.CaseA 59-year-old male with oropharyngeal squamous cell carcinoma, carotid artery stenosis, and multiple comorbidities underwent chemotherapy, pseudoaneurysm embolization, and carotid artery stenting. Four months after carotid artery stent placement, the patient expelled the carotid stent through an oropharyngeal fistula. Imaging confirmed a chronic fistula and occlusion of the right carotid artery. Remarkably, the patient remained hemodynamically stable due to collateral circulation, allowing for safe discharge without further intervention.ConclusionsThis case illustrates an exceedingly rare presentation of carotid artery stent expulsion through an oropharyngeal fistula in a patient with severe carotid stenosis and head and neck cancer. This case underscores the importance of vigilance in patients with high-risk comorbidities undergoing vascular interventions for head and neck cancers. It also adds to the literature by highlighting a potential, albeit rare, complication of carotid stenting in the context of oropharyngeal malignancy.

晚期头颈癌患者颈动脉支架经口咽瘘排出一例罕见病例研究。
目的本病例报告旨在描述一名59岁男性头颈癌患者经口咽瘘(OCF)取出颈动脉支架的罕见且严重的并发症。该研究强调了口咽癌和颈动脉爆裂之间独特的相互作用,并强调了OCF在晚期合并症患者中的新表现。病例1:59岁男性,口咽鳞状细胞癌,颈动脉狭窄,并有多种合并症,接受化疗,假性动脉瘤栓塞,颈动脉支架植入术。颈动脉支架置入4个月后,患者通过口咽瘘排出颈动脉支架。影像学证实慢性瘘管和右颈动脉闭塞。值得注意的是,由于侧支循环,患者血流动力学保持稳定,无需进一步干预即可安全出院。结论:本病例为颈动脉严重狭窄合并头颈癌患者罕见的颈动脉支架经口咽瘘排出。本病例强调了高危合并症患者在接受头颈癌血管介入治疗时保持警惕的重要性。它也增加了通过强调潜在的,虽然罕见的,颈动脉支架置入口咽恶性肿瘤的背景下并发症的文献。
