[摘要] 胸主动脉内膜血管支架置入术(TEVAR)治疗急性/亚急性非复杂性Stanford B型主动脉夹层优于最优内科治疗。TEVAR实施的最佳时间窗为2周~6个月。TEVAR可以用于治疗慢性非复杂性Stanford B型主动脉夹层。虽然TEVAR存在操作并发症,但仍是相对安全有效的治疗非复杂性Stanford B型主动脉夹层的方法。

[Abstract] Thoracic endovascular aortic repair (TEVAR) treatment is superior to the best medical treatment for acute/subacute uncomplicated Stanford type B aortic dissection. The best time window of TEVAR treatment is from 2 weeks to 6 months. TEVAR can be used for treatment of chronic uncomplicated Stanford type B aortic dissection. Although there are complications of TEVAR, but it is still relatively safe and effective in the treatment of uncomplicated Stanford type B aortic dissection.

主動脉夹层是循环中血液经主动脉内膜病变进入主动脉壁造成动脉壁分离及血肿形成的疾病。目前主动脉夹层根据解剖学特点有两种分类方法,Stanford和DeBakey分型。根据发病时间分为急性(<14 d)及慢性(≥14 d)。根据复杂性分为非复杂性和复杂性。非复杂性Stanford B型主动脉夹层中的“非复杂性”是指无动脉瘤扩展、破裂或频临破裂、灌注不良综合征、疼痛和难于控制的高血压存在。目前对于Stanford B型主动脉夹层的治疗手段包括内科药物治疗、腔内治疗及外科手术。Stanford B型主动脉夹层累及降主动脉,占主动脉夹层的25%~40%,接近75%的患者为非复杂性。对于非复杂性Stanford B型主动脉夹层根据时间分期不同选择治疗不同。以往主动脉夹层分期只有急性和慢性,但近年来的许多临床研究将其分为急性、亚急性及慢性期。对于急性/亚急性期患者主要治疗手段为胸主动脉内膜血管支架置入术(thoracic endovascular aortic repair,TEVAR)和最优内科治疗(best medical treatment,BMT)[1]。慢性期患者如果存在动脉瘤变性则需考虑外科手术。TEVAR对于非复杂性Stanford B型主动脉夹层是否作为首选治疗存在争议。……
