目的
2
报道1例鼻咽癌(nasopharyngeal carcinoma,NPC)放疗后发生颈动脉重度狭窄合并严重直立性低血压(orthostatic hypotension,OH)的病例,并探讨其病理生理机制。
方法
2
总结1例以反复头晕、直立不耐受为突出表现的NPC放疗后患者的诊疗经过及长期随访结果,通过检索相关文献,对本病例潜在的病理生理机制进行分析。
结果
2
本例患者因NPC颈部放疗导致放射性颈动脉狭窄(radiation-induced carotid artery stenosis,RICS)及颈动脉窦区压力感受器衰竭,单纯行左侧颈内动脉支架置入术未能缓解患者的直立不耐受。入院后确诊为OH合并低钠血症,予以静脉补钠扩容及活动前口服盐酸米多君片治疗,头晕及直立不耐受症状显著改善并顺利出院。长期随访提示患者虽仍有直立性头晕症状,但程度较前减轻,未再出现晕厥前兆。
结论
2
放射性动脉狭窄常与自主神经压力感受器功能衰竭协同致病,临床诊治有头颈部放疗史的脑梗死或头晕患者时,应常规行卧立位血压及脑血流动力学监测以指导综合干预。
Objective
2
To report a case of severe carotid artery stenosis comorbid with profound orthostatic hypotension(OH) after radiotherapy for nasopharyngeal carcinoma(NPC),and to investigate its underlying pathophysiological mechanisms.
Methods
2
The diagnosis and treatment process and long-term follow-up results of a patient with recurrent dizziness and orthostatic intolerance after radiotherapy for NPC were summarized,and related articles were searched to analyze the potential pathophysiological mechanisms of this case.
Results
2
In this case,neck radiotherapy for NPC led to radiation-induced carotid artery stenosis (RICS) and baroreceptor failure in the carotid sinus region,and consequently,internal carotid artery stenting at the left side alone failed to alleviate orthostatic intolerance. After admission,the patient was diagnosed with OH and hyponatremia and was treated with intravenous sodium supplementation for volume expansion and oral administration of midodrine hydrochloride tablets before activity. The symptoms of dizziness and orthostatic intolerance were significantly improved,and the patient was discharged successfully. Long-term follow-up showed that although orthostatic dizziness persisted,there was a reduction in its severity,and no pre-syncope episodes occurred.
Conclusion
2
Radiation-induced arterial stenosis and autonomic baroreceptor failure often act synergistically to cause disease,and for the diagnosis and treatment of patients with cerebral infarction or dizziness and a history of head-and-neck radiotherapy,active supine-to-standing blood pressure monitoring and cerebral hemodynamics assessments should be performed as routine screening modalities to guide comprehensive intervention.
