血管内支架治疗鼻咽癌放疗后颈动脉狭窄6例分析

目的 探讨血管内治疗鼻咽癌放疗后颈动脉狭窄的有效性及安全性.方法 选取2010-01-2011-12治疗的6例鼻咽癌患者,已行放射治疗,经脑血管造影检查颈动脉重度狭窄（狭窄率＞50%）,行颈动脉球囊扩张及支架置入治疗,并随访至少12个月.结果 随访发现支架内再狭窄1例,再狭窄率16.7%.结论 血管内治疗是鼻咽癌放疗后颈动脉狭窄的有效治疗手段,其创伤小,围手术期并发症少,随着技术的进步及器材的改进,其疗效及安全性正逐渐提高.

Endovascular stents in treating cervical artery stenosis after radiotherapy in 6 cases of nasopharyngeal carcinoma

Objective To investigate the therapeutic effect of endovascular stents for cervical artery stenosis after radio- therapy in patients with nasopharyngeal carcinoma （NPC）. Methods Six cases of nasopharyngeal carcinoma patients, suffering severe carotid artery stenosis （stenosis〉50%） after radiotherapy, examined by cerebral angiography from January 2010 to De-cember 2011, were treated with carotid artery balloon angioplasty and endovascular stent implantation, and took follow-up for at least 12 months. Results During the following-up, only one restenosis in stents was found in all the patients, and the restenosis rate was 16.7%. Conclusion Endovascular stent implantation is effective for treating patients with NPC suffering cervical artery stenosis after radiotherapy, which is less invasive, fewer perioperative complications, increasing efficacy and safety with advances in technology and equipment.
