目的探讨血管内支架置入术治疗鼻咽癌放疗后的颈动脉狭窄或闭塞病变的疗效。方法对3例鼻咽癌患者放疗后出现严重动脉狭窄或闭塞病变的颈部血管行球囊成形术及支架置入术并进行随访。结果 3例患者均为男性,其中1例为双侧颈动脉闭塞,进行了一侧颈动脉闭塞病变再通术;1例为双侧颈动脉重度狭窄,进行了左侧颈动脉支架成形术;1例右颈内动脉起始段严重狭窄,左侧颈动脉闭塞,对右侧颈动脉严重狭窄处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是治疗鼻咽癌放疗后颈部血管重度狭窄或闭塞病变的有效手段。
Objective To investigate the therapeutic effect of endovascular stenting on carotid artery stenosis or occlusion after radiotherapy of nasopharyngeal carcinoma. Methods Three cases of nasopharyngeal carcinoma patients with severe arterial stenosis or occlusion after balloon angioplasty and stenting were performed and followed up. Results All 3 patients were male, including 1 case of bilateral carotid artery occlusion and one case of recanalization of carotid artery occlusion. One case was severe bilateral carotid stenosis with left carotid stenting. One case had severe stenosis at the beginning of the right internal carotid artery, occlusion of the left carotid artery, and endovascular stent placement on the right carotid stenosis. No stent stenosis was found after follow-up. Conclusion Endovascular stenting is an effective method for the treatment of severe stenosis or occlusion of the neck in patients with nasopharyngeal carcinoma after radiotherapy.
