【摘要】 目的探讨血管内自膨式支架技术治疗症状性颈内动脉起始段狭窄的临床效果。 方法对26例患者颈内动脉起始段狭窄的患者行全脑血管造影,依照北美有症状颈动脉内膜切除试验测量标准,判断颈动脉狭窄程度,对狭窄率>50％的患者置入自膨式支架,术中5例行球囊预扩张,3例应用保护装置。结果 26例支架置入均获成功,血管残余狭窄程度<30％。术后随访23例(10-22个月),1例发生再狭窄(狭窄率>55％)。结论 血管内支架成形术是治疗颈动脉狭窄的一种有效方法,至于术后存在的血栓形成、再狭窄等问题还有待于今后进一步研究。更多还原

【Abstract】 Objective To discuss the value of percutaneous transluminal stenting in treating extracranial carotid stenosis. Methods The course and results of treatment of percutaneous transluminal stenting forextracrarial carotid stenosis were analysed retrospectively. 26 patients were received cerebral angiography to comprehend the condition of cerebral vessels, then they were treated with percutaneous transluminal self-expanding stenting. During the operation, predilation with the balloon was used in 5 patients, cerebral protection of filter devices were used in 3 patients. Results All the stents were successfully placed and residual stenosis was < 30%. The heart ratesdecreased in 16 patients, hemiplegia and aphasia happened in 4 patients, cerebrovascular spasm were noticed in 2 patients. Restenosis occurred in 1 patient. Conclusion Percutaneous transluminal stenting is a hopeful method to treat extracrarial carotid stenosis, and further study is need to be done on postoperative thrombosis and restenosis.更多还原
