血管内支架治疗鼻咽癌放疗后颈部血管狭窄2例并文献复习

Endovascular Stents Treatment Cervical Artery Stenosis of Nasopharyngeal Carcinoma after Radiotherapy in 2 Cases and literature Review

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 therapeutic effect of the endovascular stents for the cervical artery stenosis of nasopharyngeal carcinoma（NPC）after radiotherapy.Materials and Methods The balloon angioplasty and endovascular stent implantation had been used successfully to treat severe carotid stenosis of 2 patients with NPC after radiotherapy and then patients had been followed-up.Results Among 2 cases.1 is a male,the other is a female.We used the balloon angioplasty and endovascular stent implantation by stages for the patient（male） who had bilateral internal carotid artery severe stenosis.The woman suffered from the left carotid artery stenosis and right vertebral artery stenosis,we used the endovascular stent treatment for 2 stenosis at the same time.After following-up,we did not find restenosis in stents.Conclu-sion The endovascular stent implantation is an effective treatment method for cervical artery stenosis of NPC after the radiotherapy.
