目的探讨颈动脉颅外段狭窄支架成形术的手术方法、并发症及安全性。方法选择有症状性颈动脉狭窄≥50%的患者,无症状性颈动脉狭窄≥70%的患者为其适应证。使用自膨胀式支架和保护装置,进行支架置入成形术。结果61例患者,置入70枚支架,配合28个保护装置。支架成功率100%,术中无中风并发症出现,即刻血管造影显示满意,平均术后血管残留狭窄约8%。所有患者均获随访,分别采用颈部X线及超声波检查及血管造影,再狭窄1例,其余支架形态好,位置无移位,血流通畅,无再狭窄。结论血管内支架成形术治疗颈动脉颅外段狭窄有效、并发症少、安全性高。 Objective To investigate the surgical methods, complications and safety of extracranial carotid stenosis stenting. Methods Patients with symptomatic carotid stenosis ≥50%, asymptomatic carotid stenosis ≥70% were selected as indications. Stent placement is performed using a self-expanding stent and protector. Results In 61 patients, 70 stents were placed with 28 protection devices. Stent success rate of 100%, intraoperative non-stroke complications, immediate angiography showed satisfactory, the average postoperative vascular residual stenosis of about 8%. All the patients were followed up. Neck X-ray, ultrasonography and angiography were performed respectively. One case was restenosis. The rest of the stent was in good shape with no displacement of position, blood flow was smooth and no restenosis. Conclusion Endovascular stenting is effective in the treatment of extracranial stenosis of carotid artery with less complications and high safety.
