目的探讨血管内支架置入术对于鼻咽癌放疗后的颈动脉狭窄的疗效。资料与方法对2例鼻咽癌患者放疗后出现严重狭窄的血管行球囊成形术及支架置入术并进行随访。结果2例患者中1例为男性,1例为女性,其中1例有双侧颈内动脉起始段严重狭窄,分期对2侧病变血管进行了血管内支架治疗;1例左颈内动脉起始段严重狭窄,右椎动脉起始段严重狭窄,同时对2处严重狭窄进行了血管内支架治疗;经过随访并未发现有支架内再狭窄。结论血管内支架置入术对于鼻咽癌放疗后颈部血管重度狭窄是一种有效的治疗手段。
Objective To investigate the effect of endovascular stenting on carotid artery stenosis after radiotherapy of nasopharyngeal carcinoma. Materials and Methods 2 cases of nasopharyngeal carcinoma patients with severe stenosis after balloon angioplasty and stenting were followed up. Results One patient was male and one patient was female. One patient had severe stenosis at the beginning of bilateral internal carotid artery and endovascular stenting was performed on the 2-vessel lesion in one patient. One patient developed left carotid artery Serious stenosis at the beginning, severe stenosis at the beginning of the right vertebral artery, and endovascular stenting of two severe stenoses at the same time; no in-stent restenosis was found after follow-up. Conclusion Endovascular stent placement is an effective treatment for severe stenosis of cervical vessels after radiotherapy of nasopharyngeal carcinoma.
