放疗后颈动脉狭窄的研究进展

Progress in the Research of Carotid Stenosis After Radiotherapy

随着治疗手段的进步，肿瘤患者治疗后的存活期明显延长。但同时，头颈部肿瘤患者放疗后颈动脉狭窄的发现率日益增高。研究表明，放疗后颈动脉狭窄是放疗的多种破坏作用与其他危险因素共同作用所致。目前最主要的诊断手段为颈部多普勒超声。随着血管成形和支架置入术的应用，放疗后颈动脉狭窄的治疗效果也得到了改善。文章综述了放疗后颈动脉狭窄的病理学、发病机制、诊断和治疗。

With the irnprovement of therapeutic tools, the survival time in patients with tumor is prolonged significantly. Hov, ever, at the same time the discovery rate of carotid stenosis after radiotherapy in patients with head and neck tumors is increasing. Studies have suggested that carotid stenosis after radiotherapy results from the interaction of various destructive effects of radiotherapy and other risk factors. At present, the most important diagnostic means is cervical Doppler ultrasound. With the application of carotid angioplasty and stenting, the therapeutic efficacy of carotid stenosis after radiotherapy has been also improved. This article reviews the pathology, pathogenesis, diagnosis and treatment of carotid stenosis after radiotherapy.
