Type B aortic dissection (TBAD), is defined as a dissection involving the aorta distal to left subclavian artery with the ascending aorta and the aortic arch not affected. TBAD is classified due to the time frame and presence of complications. Complicated TBAD (co-TBAD) patients have a greater mortality rate than uncomplicated TBAD (un-TBAD) and thoracic endovascular aortic repair (TEVAR) is considered the gold-standard intervention for these clinical challenges.

TEVAR 用于复杂性和非复杂性 B 型主动脉夹层——系统评价和荟萃分析

B型主动脉夹层（TBAD），定义为涉及左锁骨下动脉远端主动脉的夹层，升主动脉和主动脉弓不受影响。TBAD 根据时间范围和并发症的存在进行分类。复杂性 TBAD (co-TBAD) 患者的死亡率高于非复杂性 TBAD (un-TBAD)，胸主动脉腔内修复术 (TEVAR) 被认为是应对这些临床挑战的金标准干预措施。
