摘　　要：TEVAR术现已是治疗胸B型主动脉夹层(TBAD)的一线治疗,在基层医院,在TEVAR术中,血运重建未得到开展,其他的手术方法都会覆盖LSA,会导致LSA血运减少,进而使左椎动脉(LVA)优势型TBAD患者左上肢缺血,出现左上肢血压相比右上肢下降,左上肢麻木或功能障碍等症状。TEVAR surgery is now the first line treatment for aortic dissection (TBAD). In grassroots hospitals, TEVAR surgery routinely covers part or all of the left subclavian artery, and many techniques have not been developed;In TEVAR surgery, except for revascularization, other surgical methods will more or less cover a portion of the left subclavian artery, which will lead to a decrease in blood sup-ply to the left subclavian artery, leading to ischemia in the left upper limb of patients with left ver-tebral artery dominant type TBAD, resulting in a decrease in blood pressure in the left upper limb compared to the right upper limb, numbness or dysfunction in the left upper limb.

关 键 词：B型主动脉夹层 左椎动脉 左锁骨下动脉 左上肢
