近年来胸主动脉腔内修复术(TEVAR)在Stanford B型主动脉夹层的治疗中取得了显著的疗效.主动脉弓结构复杂、曲度大、弓上分支血管负责脑部和上肢等重要区域的血供,其中左锁骨下动脉包含椎动脉等重要分支,负责左上肢、后脑部等的血供.为了保证足够的锚定区,当近端裂口距左锁骨下动脉开口距离＜1.5 cm时需对左锁骨下动脉做相应处理,现对Stanford B型主动脉夹层腔内修复术中左锁骨下动脉的处理予以综述.“,”In recent years,thoracic endovascular aortic repair (TEVAR) has shown promising results for Stanford type B aortic dissection.The aortic arch has a complex structure,with non-planar curvature and its supra-aortic arch branches are supplying vessels of the brain,upper limbs and other important areas,in which the left subclavian artery gives offimportant branches that include the vertebral artery perfusing the left upper limb and posterior portion of the brain.For ensuring sufficient landing zone,some special treatments should be made if the distance between proximal entry tear and the opening of the left subclavian artery is less than 1.5 cm.Here,the authors address the treatments of the left subclavian artery during endovascular repair of Stanford type B aortic dissection.
