目的探讨腔内修复术治疗右椎优势的Stanford B型胸主动脉夹层时完全封闭左锁骨下动脉后对患者的影响。方法对16例接受腔内修复术治疗,并在术中完全封闭左锁骨下动脉的右椎优势的Stanford B型胸主动脉夹层患者进行回顾性分析,观察右椎优势的Stanford B型胸主动脉夹层在术中完全封闭左锁骨下动脉后的临床不良反应。结果 16例患者中3例有短暂的头晕症状,13例无临床不良反应。结论腔内修复术治疗右椎优势的Stanford B型胸主动脉夹层时完全封闭左锁骨下动脉不会引起的急性后循环缺血造成严重的并发症。
Objective To investigate the impact of occlusion of left subclavian artery on patient with right vertebral advantage who were underwent endovascular therapy for thoracic aortic dissection of the type of Stanford B. Methods Retrospective analysis of the clinical data of 16 patients with right vertebral advantage who were underwent endovascular therapy for thoracic aortic dissection of the type of Stanford B were carried out, and the outcomes were analyzed. Results Three patients whose left subclavian artery were occluded completely had symptom of syncope, and the left 13 cases showed no clinical symptoms. Conclusion It is safe to completely occlude the left subclavianartery in patients of Stanford B thoracic aortic dissection with right vertebral advantage when performing endovascular therapy.
