Acute complicated type B aortic dissection (TBAD) is a potentially catastrophic, life-threatening condition. If left untreated, there is a high risk of aortic rupture, irreversible organ or limb damage, or death. Several risk factors have been associated with acute complicated TBAD, including age and refractory hypertension. In the acute phase, even uncomplicated patients are more prone to develop complications if hypertension and pain are left medically untreated. Innovations in stent graft technologies have incrementally improved outcomes since their first use for this condition in 1999, though improvement is needed in mitigating periprocedural complications, adverse events, and mortality. In the past decade, endovascular repair has become the preferred treatment because of its superior outcomes to open repair and medical therapy. The Valiant Captivia Thoracic Stent Graft System is a third-generation endovascular stent graft with advancements in minimally invasive delivery, conformability to the anatomy, and the minimization of adverse sequelae. Herein, this stent graft is briefly reviewed and its 3-year outcomes are presented. Freedom from all-cause and dissection-related mortality was 79.1% and 90.0%, respectively. The Valiant Captivia Stent Graft represents a safe, effective intervention for acute complicated TBAD. Continued surveillance is needed to verify its longer-term durability.
急性复杂性B型主动脉夹层(TBAD)是一种潜在的灾难性、危及生命的疾病。如果不进行治疗,主动脉破裂、不可逆转的器官或肢体损伤或死亡的风险很高。几个风险因素与急性复杂性TBAD相关,包括年龄和难治性高血压。在急性期,如果高血压和疼痛不进行药物治疗,即使是未并发的患者也更容易出现并发症。自1999年首次用于治疗这种疾病以来,支架移植物技术的创新逐步改善了治疗效果,不过在减轻围手术期并发症、不良事件和死亡率方面仍需改进。在过去十年中,血管内修复因其优于开放修复和药物治疗的效果而成为首选治疗方法。Valiant Captivia胸主动脉支架移植物系统是第三代血管内支架移植物,在微创输送、对解剖结构的顺应性以及不良后遗症的最小化方面取得了进展。在此,对这种支架移植物进行简要综述并介绍其3年的治疗效果。全因死亡率和与夹层相关的死亡率分别为79.1%和90.0%。Valiant Captivia支架移植物是治疗急性复杂性TBAD的一种安全、有效的干预措施。需要持续监测以验证其长期耐用性。
