Patients with type B aortic dissection (TBAD) often present as an emergency. Operative repair of TBAD can be indicated for selected patients in the setting of hemodynamic instability or rupture. Thoracic endovascular aortic repair of TBAD has achieved significant popularity. Variant aortic arch anatomy can present a significant clinical challenge in patients with an inadequate proximal landing zone for thoracic endovascular aortic repair. A three-stage, hybrid aortic arch debranching and endovascular repair of a ruptured TBAD in a patient with a bicarotid trunk and an aberrant right subclavian artery was successfully performed using a unique technical approach.
B型主动脉夹层(TBAD)患者常以急症形式出现。对于血流动力学不稳定或破裂情况下的部分患者,可考虑对TBAD进行手术修复。TBAD的胸主动脉腔内修复术已颇受欢迎。在胸主动脉腔内修复术近端锚定区不足的患者中,主动脉弓解剖变异可能带来重大临床挑战。采用独特的技术方法,成功地为一名具有双侧颈总动脉干和迷走右锁骨下动脉的患者实施了破裂TBAD的三阶段杂交主动脉弓去分支和腔内修复术。
