Type B aortic dissection (TBAD) is a rare but catastrophic complication of endovascular aneurysm repair (EVAR). We report two cases of TBAD occurring in the perioperative period of EVAR. The intraoperative and postoperative courses were unremarkable. Routine postoperative computed tomography angiography (CTA) revealed TBAD. Conservative treatment was successful, and no adverse aortic events occurred. TBAD that occurs in the perioperative period is likely to be iatrogenic in origin, uncomplicated, and managed with medical therapy: its prognosis is better than when the condition develops in the midterm postoperative period.
B型主动脉夹层（TBAD）是血管内动脉瘤修复术（EVAR）一种罕见但灾难性的并发症。我们报告两例在EVAR围手术期发生的TBAD。术中和术后过程均无异常。术后常规计算机断层扫描血管造影（CTA）显示为TBAD。保守治疗成功，未发生不良主动脉事件。围手术期发生的TBAD可能起源于医源性，不复杂，采用药物治疗：其预后优于术后中期发生的情况。
